high-grade iron ore supply to struggle to meet demand as china decarbonizes: mi | s&p global platts

The S&P Global Platts 62% Fe index, IODEX, reached a record $233.1/dmt on May 12 driven by a resurgence in global demand, tightening supply and runaway steel prices. Although the IODEX eased back slightly in early June, iron ore and steel will be key beneficiaries of the infrastructure investment drive in China and the US, as well as from the global renewable energy transition over the medium to long term, through the rollout of new infrastructure for power generation, electric vehicle charging and high-speed electric rail networks. With a global steel production recovery underway, S&P Global Market Intelligence expects the iron ore seaborne trade deficit to deepen in 2021 and remain in deficit to 2025.

The Chinese steel industry aims to reach peak carbon emissions by 2025 and achieve a 30% reduction from the peak by 2030. These targets are set in accordance with the country's overall plan to see carbon emissions peak by 2030 and achieve carbon neutrality by 2060.

The decarbonization push is expected to boost demand for direct feed iron ore products pellet and lump. Unlike iron ore fines, which need to be sintered with coke breeze and anthracite coal first, direct feed ores are directly charged to blast furnaces, emitting less pollution including carbon. Therefore, the Tangshan government has embarked on a scheme to reduce emissions at 23 local mills by 30%-50% by the end of 2021, with sintering operations bearing the brunt. Other Chinese regions may adopt similar measures to reduce carbon emissions in future.

Demand for high-grade ore is also expected to benefit from decarbonization due to its lower impurities and the higher productivity that it offers. Impurities such as alumina and silica in ore need to be removed using coke and limestone in iron making. Iron ore with lower impurities consumes less coke and limestone and therefore emits less carbon. Furthermore, the decarbonization push could constrain steel supply. The Ministry of Industry and Information Technology has called on Chinese mills to reduce crude steel output in 2021, citing this as the most effective way to constrain carbon emissions. Amid strong steel demand, pockets of steel production curbs helped to propel Chinese steel margins to historical highs in May 2021, boosting demand for high-grade ore, including pellet, concentrate, lump and high-grade fines.

Australia is the single biggest source of iron ore supply to China, accounting for 61% of Chinese imports in 2020. The escalating political tensions between the two countries, however, have driven China to look for alternative supply sources.

Indian iron ore exports over recent years have helped to fill shortages in the seaborne market. Surging coronavirus cases in India, however, are fueling fears of a supply crunch in 2021, while rising domestic demand is expected to reduce exports in coming years. A moratorium on mining in Goa is limiting the upside for Indian exports.

Global iron ore supply will struggle to keep pace with demand. Major producers with operations in the low-cost mining hubs of Australia and Brazil are expected to dominate export growth, with a shift towards increasing supply of high-grade ore to help meet tightening carbon emissions standards in the global steel sector. With few greenfield projects in the pipeline and ESG hurdles steepening, S&P Global Market Intelligence expects most of the seaborne supply growth to derive from restarts of shuttered capacity in Brazil, following the Brumadinho dam disaster in early 2019, and brownfield expansions.

Vale's first quarter iron ore production annualized to 327 million mt but the company is targeting 400 million mt/y at the end of 2022. The company continues to make steady progress on its operational stabilization and resumption plan. This has led to gradual restarts at Fbrica, Timbopeba and Serra Leste mines and at the Vargem Grande pellet plant. Three additional beneficiation lines at Timbopeba will boost capacity from 7 million mt/y to 12 million mt/y in the second quarter of 2021. Northern System mine supply is expected to rise by 24 million mt by 2023, with S11D increasing from 83 million mt in 2020 to 100 million mt from the second half of 2022, while the commissioning of the Gelado project will convert iron tailings into high grade products. Itabira and Mutuca mines, however, are operating under temporary tailings disposal restrictions, despite Vale targeting 50 million mt of supply growth from mines in the Southern and Southeastern Systems by 2023.

With Vale seeking to remediate numerous shuttered tailings dams, the supply recovery is constrained by difficulties in obtaining necessary safety approvals to reopen, amid Brazilian legislators' heightened safety consciousness following two major disasters. Finding a lasting waste disposal solution is key to the ramp up of Samarco's pellet facility, which restarted in December 2020 having been offline since the Fundo tailings dam collapse in November 2015. Samarco is targeting production at 7-8 million mt in 2021, before ramping up to 22-24 million mt in 2029. CSN plans to increase capacity at its Casa de Pedra mine from 30 million mt in 2020 to 108 million mt/y by 2033. The company is at fund-raising stage, helped by a recent IPO of its mining unit, and consequently will see most of the supply growth arriving post 2025. Brazilian ores typically have high iron content and low levels of silica and alumina. Brazil is also the world's biggest producer of pellet and direct reduction-grade iron ore.

Australian iron ore shipments are expected to increase to 977 million mt in 2025, with the average iron content expected to rise thanks to more supply from high-grade mines and a reduction in lower grade product. BHP has recently started production at its South Flank sustaining mine project, located at the company's Western Australian Iron Ore hub, with a capacity of 80 million mt/y. South Flank will replace its Yandi mine, which is nearing the end of its mine life, and will lift average Fe grade from 61% to 62%, along with raising the share of lump output from 25% to 30%-33%.

Rio Tinto's $2.6 billion Gudai-Darri mine replacement project in the Pilbara is expected online in early 2022. The first phase has a 43 million mt/y capacity and will lift the lump to fines ratio for its Pilbara Blend shipments to 38%. The company has also approved a pre-feasibility study for a second phase expansion to 70 million mt/y and will see increased supply from its operations at Robe Valley, West Angelas and Tom Price following recent growth-targeted investments. While the Pilbara boasts huge potential for future supply growth, producers require the necessary 'social license' to develop new sites, as highlighted by the fallout from Rio Tinto's destruction of the Juukan Gorge caves, an aboriginal heritage site, to facilitate an iron ore expansion project.

FMG aims to produce higher grade iron ore products lifting its average Fe content from 58% to 60-62%. The company is developing the Western Hub in the Pilbara, this includes its recent high-grade replacement mine start, Eliwana, with a capacity of 30 million mt/y. The company's 22 million mt/y Iron Bridge magnetite concentrate project is under development and will deliver 67% Fe content product, with low alumina and phosphorus. Significant expansion potential could be in the pipeline at the Chinese backed CITIC Sino Iron high-grade magnetite operation at Cape Preston, in Western Australia. A long running dispute over land access to store mine residue will need to be resolved, however, while being a high cost operation remains an ongoing problem for Sino Iron.

Iron ore supply concerns have prompted calls from China's National Development and Reform Commission for more exploration in China and for a diversification of the country's imports, with shipments from Russia, Kazakhstan, Mongolia and South East Asia likely increasing over the medium term a similar trend was seen in 2009-2013.

Amid heightened political tensions between China and Australia, West Africa will provide the best opportunities for China to diversify its supply over the long term. The Simandou deposit in Guinea can potentially yield 200 million mt/y of high-grade iron ore. SMB-Winning - a Chinese-Singaporean-Guinean consortium is aiming to commission production from Blocks 1-2 in 2025, although S&P Global Market Intelligence anticipates a 2027 earliest likely start. Blocks 3-4 are under a consortium of Rio Tinto, China Aluminum Corp. and the Guinean government. However, major capital expenditure will be required to build mine, rail and port infrastructure given Simandou's greenfield status.

In Liberia, meanwhile, ArcelorMittal is mooting a second phase expansion project at its Yekepa mine which is aimed at boosting exports from 5 million mt/y to 15 million mt/y from 2023 onwards. The expansion will be focused on exports of high-grade concentrate.

In summary, restarts, brownfield expansions and replacement mines are expected to support global iron ore supply growth. However, S&P Global Market Intelligence expects the market to remain in deficit in the medium term with supply growth hampered by steepening ESG hurdles and lack of greenfield projects, while demand is expected to rise as global steel production recovers from the 2020 low. The decarbonization drive in the steel industry is expected to reinforce the premiums of direct feed and high-grade iron ore, favoring miners with such options in their supply pipelines.

iron ore beneficiation plant, iron ore crushing and grinding machine

SBM is a iron ore machine manufacturer in China, and supplies rock crushers and grinding mills for iron ore beneficiation plant. The most commonly used crushers and grinding mills in iron ore crushing and grinding process for iron ore mining are Jaw Crusher, Cone Crusher, Hammer Crusher and Ball Mill, SCM Super-Micro Mill, etc. In iron ore mining, miner usually choose a complete iron ore crushing plant for metallurgy.

Almost all of the iron ore that is mined is used for making steel. So we need the extraction of a pure metal from its ore. The extract the metal from ores, several physical and chemical methods are used. The method used depending upon chemical properties and nature of the ore from which it is to be extracted. It involves four main steps:

iron ore crushing plant, iron ore beneficiation and mining equipment video, pic, pdf used in india,china, malaysia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red.

According to the various sources of iron as well as certain economic and safety aspects in regards to its extraction is included, we provide you with a suitable iron ore mining equipment. The course we provide information of Iron ore processing includes comprehensive information on the beneficiation of iron ore including comminution, sintering, upgrading, and pelletizing aspects.

The iron ore is distributed in Algeria,Egypt,Ghana,Kenya,Nigeria,South Africa,Sudan,Zambia,Zimbabwe,China,Russia,Australia,New Zealand,France,Germany,Iceland,Italy,Luxembourg,Netherlands,Norway,Spain,Sweden,Switzerland,Ukraine,United Kingdom,Canada,Cuba,Mexico,United States,Brazil,Chile,Peru,Venezuela,

Iron ores are typically used for the production of iron. Then the iron produced is to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.

Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse. Common iron ore crushers are jaw crusher, cone crusher and fine jaw crusher.

You will obtain three kind of iron ore particles after screening, respectively of 75~12mm, 12~2mm, 2~0mm in size. The largest ore particles pass to dry magnetic separation with shaking chute, the middle ones are moved to dry magnetic separator with coarse jigging, and the smallest to wet magnetic separator with fine jigging. The middlings produced by three processes are moved to screening process. The tailings of wet magnetic separation will be discharged directly.

After the second crushing machine, iron ore particles are moved to secondary crushing and the first ball mill grinding. With fine ore particles, it is more efficient to upgrade iron ore. Wet ball mill and fine ore crushers are used during this process.

The obtained iron ore mines materials are moved to flotation desulfurization process, then to weak magnetic separation. The obtained product is iron ore concentrate. And low iron content material is discharged as tailings. You will also obtain sulphide concentrate as by-product through flotation desulfurization.

In the United States, almost all of the iron ore that is mined is used for making steel. The same is true throughout the world. Raw iron by itself is not as strong and hard as needed for construction and other purposes. So, the raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks, trains and train tracks.

While the other uses for iron ore and iron are only a very small amount of the consumption, they provide excellent examples of the ingenuity and the multitude of uses that man can create from our natural resources.

Powdered iron: used in metallurgy products, magnets, high-frequency cores, auto parts, catalyst. Radioactive iron (iron 59): in medicine, tracer element in biochemical and metallurgical research. Iron blue: in paints, printing inks, plastics, cosmetics (eye shadow), artist colors, laundry blue, paper dyeing, fertilizer ingredient, baked enamel finishes for autos and appliances, industrial finishes. Black iron oxide: as pigment, in polishing compounds, metallurgy, medicine, magnetic inks, in ferrites for electronics industry.

In accordance with the characteristics of mineral composition, structure, construction and mining, sorting, Metallurgical and process iron ore is divided into two major categories of the type of natural and industrial type.

1) According to the iron-bearing mineral species can be divided into: magnetite ore, hematite iron ore, the illusion, or semi martite iron ore, vanadium-titanium magnetite ore, limonite, siderite iron ore as well as by one of two or iron mineral composition of two or more kinds of mixed ore.

2) Press the harmful impurities (S, P, Cu, Pb, Zn, V, Ti, Co, Ni, Sn, F, As) content of the high and low, can be divided into high-sulfur iron ore, iron ore of low sulfur, high phosphorus iron ore, low phosphorus iron ore.

3) According to the structure, the structure can be divided into disseminated ore stockwork disseminated ores, striped ore, banded ore, the dense massive ore, brecciated ore and oolitic, bean-shaped, kidney-shaped honeycomb , powder, earthy ore.

wet beneficiation of low grade iron ores, or tailings of 35-54% fe grades in the fluidised bed reduction-roasting plant & subsequent pelletisation in the vertical shaft kiln goodrich magma industrial technologies limited

GoodRich offers a new technology from China, which can beneficiate low grades of hematite / limonite / goethite ores (including BHQ & BHJ) and also recover the left-over tailings from the conventional beneficiation plants, by converting them into magnetite ores, using the fluidised bed reduction-roasting method. Once the iron ore becomes magnetite, it is much easier to beneficiate & pelletise it.

The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) & the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants).

In the process, low grade iron ores are dry-ground, preferably to their liberation size & passed through a fluidized bed roaster. The process uses coal gas for pre-heating & for partial reduction. Hematite / limonite / goethite ores get converted into magnetite ore in 1-10 minutes depending on the size of iron ore, at temperatures of 500-600 degree C. The left-over heat, after reduction, is utilized for 3 stage pre-heating of iron ore.

After being converted into magnetite, the ore is quenched in water & passed through low gauss magnetic separators, to reach 60-65% Fe grades. If the silica content is high, floatation process may also be employed.

Coal consumption is 90 kgs per ton of raw material (60 kgs by way of coal gas for reduction & 30 kgs by way of heat for drying). Power consumption is 40 KWh per ton for dry grinding in the ball mill (or 28 KWh in Raymond mill) and 20 KWh for other processes. The available plant capacities are from 200,000 tons to 1,000,000 tons per year, based on the input. After 50 years of research in this area, China has built the first plant of 200,000 tons per year, which is currently running well.

The apparent disadvantages of the above process are in addition to iron ore, coal is also needed & the capital investment on the beneficiation plant is comparatively high. However, looking at the fact that the recovery is higher& subsequent pelletisation needs lower capital investment and has lower production cost, reduction-roasting technology can be the future of beneficiation & pelletisation in India.

The hematite ore (Fe2O3) is always associated with limonite & goethite ores, which cannot be attracted by high gauss magnetic separators in the conventional beneficiation plants. Such tailings have 30-50% left-over Fe, which is a waste of natural resources. Large quantities of tailings are also environmentally hazardous, as they occupy more space & cause heavy metal contamination in the ground water.

Such tailings can be re-beneficiated, using the fluidised bed reduction-roasting technology & employing both pyro-metallurgical (reduction-roasting) & hydro-metallurgical (low gauss magnetic separation) processes. After re-beneficiation, the secondary tailings will have only 10-15% left-over Fe. These can be sold to the cement factories (when alumina contents are high in the tailings) or used for clay brick making.

Pelletisation is the process of formation of green balls (9-16 mm) by rolling the iron ore powder with a small quantity of binder & hardening the same by heat treatment in oxidizing conditions, up to temperatures of 1,250-1,350C. As a result, binding occurs & sufficient pellet strength is developed. The process includes feed preparation (grinding & pre-drying), mixing with the binder, balling by a disc pelletiser & hardening by drying, pre-heating, firing & cooling. Magnetite ore concentrate gets re-converted into hematite ore in the pelletisation, as it is an oxidation process. The hardening of pellets can be done by the vertical shaft kiln or travelling grate furnace cum rotary kiln.

The vertical shaft kiln needs lower investments &is suitable for small capacities of 100,000 tons to 600,000 tons per year. The thermal efficiency of todays vertical shaft kiln is equal to or better than that of the chain grate furnace cum rotary kiln.

Investments on vertical shaft kiln pellet plants are approximately 50% of the investments on chain grate furnace cum rotary kiln type pellet plants. The cost of making pellets will be only Rs. 750 per ton in the vertical shaft kiln, as against to Rs. 1,500 per ton in the chain grate furnace.

The investment on a 4,00,000 tons per year reduction roasting beneficiation plant, combined with 2,50,000 tons vertical shaft kiln pelletisation plant will be Rs. 75 crores & the estimated turnover is Rs.150 crores. Larger capacity plants of 1,000,000 tons per year of beneficiation & 600,000 tons per year of pelletisation need Rs. 150 crores of investment, with a turnover potential of Rs. 360 crores. The payback periods on these investments are 2-3 years.
