sino iron project, cape preston, western australia - mining technology | mining news and views updated daily

The Sino iron project will be the worlds biggest magnetite iron ore mine when fully operational. The open-pit mine, located in Cape Preston, about 100km south-west of Karratha, Pilbara, Western Australia, will produce magnetite concentrate and pellets.

CITIC Pacific Mining Management purchased the mining rights over the property from Mineralogy, a company owned by popular entrepreneur Clive Palmer, in 2006 and initiated construction in the same year. The project employed 4,000 people during the peak construction phase.

The project was completed in 2014, approximately four years behind schedule. It consists of six production lines, of which the first two lines were operational by end of 2013. First shipment of fine iron ore from the mine was made to China in December 2013 and the project delivered 74Mt of high-grade product since exports commenced.

The project has not only suffered significant delays and consequent cost overruns but was also entangled in legal disputes with Mineralogy as the latter filed a case to cancel CITIC Pacifics mining rights over the property citing the failure of royalty payment as the reason.

Conventional open-cut mining methods including drilling, blasting, loading and hauling are used to mine iron ore from the Sino deposit. The pit will be approximately 500m-deep. Processing facilities at the mine site include a crusher, a concentrator, and a 6mt pelletising plant.

Sino Iron employed some of the worlds biggest haul trucks and excavators. Weighing 260t, the haul truck has a capacity of 340t while the main excavator weighs 1,000t and has a load capability of 4,500t of ore an hour.

The crushed ore enters grinding mills where fine ore stream is produced and transferred to magnetic separators to produce a concentrate. The concentrate is thickened and stored before pumping to the port. It is filtered to reduce moisture and exported for use in steel making.

The four in-pit crushers from Germany have a crushing capacity of crushing 4,250t of ore an hour a unit. The conveyer belt bearing crushed ore from the mine to the concentrate area is approximately 1.7km.

The main AG mill with 28MW gearless motors has a diameter of 12.2m and a length of 11m. The ball mill, the second stage grinding unit, is 7.9m in diameter and 13.6m-long. It is equipped with two 7,800kW motors.

Each of the processing lines used 52 magnetic separators, each containing seven press filters and four dewatering buildings. Each press filter has a production capability of 154t of concentrate an hour.

A 480MW power station consisting of seven SGT-800 gas turbines of 44MW each by Siemens supplies power to the plant. It also comprises three steam turbines with 58MW of capacity each and two heat recovery steam generators.

Ancillary facilities at the mine include a 140,000m a day desalination plant and a dewatering pit with a filtration area of approximately 5,600m. The EPC contract for the desalination plant was awarded to Ausenco.

Forge Group Construction was contracted for the design and construction of several facilities at the mine, including filter building structures, foundations for equipment such as stackers and tanks, as well as the main control building at the port.

Golder Associates was involved in various stages of the project right from the exploration stage to the development stage, in activities such as reviewing the reserves, on-site drilling, GIS services and tailing studies.

VDM Group subsidiary Wylie and Skene was awarded a contract by MCC for the construction of accommodation and warehouse facilities at the project site. Under a $240m 50:50 JV with NRW Civil & Mining, VDM performed earthworks at the mine.

Structural, mechanical and piping (SMP), electrical, and concrete works were carried out by Thiess. BGC Contracting built the foundations for six trains of autogenous grinding (AG) mills and pebble crushers under an $80m contract. Reinforced Earth constructed the walls for crushers three and four under a contract from BGC Contracting.

Murphy Pipe and Civil constructed concentrate, desalination and return pipelines for the mine using the equipment and personnel supplied by Orion Pipeline. MCC contracted Monadelphous for pipeworks associated with the concentrator. CADS assisted in the construction of the $20m slurry and return water pipelines.

Metso Minerals supplied mineral processing equipment for the mine. Iron ore processing equipment comprising two PE jaw crushers, one PY Cone crusher, one ball mill, one ZSW vibrating feeder, one YK vibrating screen and one conveyor belt were delivered by DSMAC.

Ball mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Besides, it is mainly applied in many industries, such as ferrous&non-ferrous metal mine, coal, traffic, light industry, etc.

The Ball mill can be divided into lattice type and overflow type according to different beneficiation methods, and this machine is two lattice-type ball mill. The materials from the feeding fittings enter the first bin of the milling machine via the feeding hollow axis evenly when it works. There is a ladder-like or ripple-like scaleboard in the first bin, and different specification steel balls are installed in the bin. When the cylinder rotates, which generating centrifugal force to carries steel balls to a certain height and then balls fall to strike and grind the material. After primary grinding in the first bin, the material then enters into the second bin via a single layer partition board. There is a scaleboard and steel balls in the second bin, so the materials are further ground. In the end, the powder is discharged by output material board.

Ball mill, a type of grinding mill, is a cylinder-shaped device used to grind materials like ores, chemicals, ceramic raw materials and paints. The ball mills are the key milling equipment after material has been crushed. It is divided into two rubbing ways-the dry and the wet. Ball mill is mainly composed of charging and discharging, cyclone and rotation parts.

Ball mill is key equipment to grind the crushed materials, and the ball mill with medium hard is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics etc. It is manufactured with the highest quality materials and workmanship and it has the advantages of high efficient, trouble free and economical combination of material ranging from (5-30mm) down to varying product sizes.

Ball Mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging materials.

According to the discharging type, ball mill could be divided into three types, overflow type ball mill, open-type ball mill and peripheral type ball mill. Overflow type ball mill is the most common one. As the first class open grinding equipment, ball mill is widely used for first class grinding equipment of concentrator, artificial sand stone and electricity sector of chemical plants. The ball mill rotation is based on deceleration motor and large gear deceleration rotation or large gear deceleration rotation which is driven by low speed synchronous motor, and then drives ball mill cylinder rotating. Steel bar, the grinding media is installed in cylinder; media is promoted to a certain height because of the joint action of friction and centrifugal force, and is dropping or falling off. The grinding materials are continuously feeding into the cylinder through inlet of ball mill, crushed by steel bar and discharge the finished products out of ball mill by overflow and continuous feeding strength then go to the next process.

China ball mills are widely used in the manufacturing industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and they can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.

Beneficiation is the process of crushing and grinding the ore according to the physical and chemical properties of different minerals in the ore to remove or reduce harmful impurities to obtain raw materials required for smelting or other industries.

Grinding and crushing are two important processes. The crushing process is usually a drying process in jaw crushers, rotary crushers and cone crushers. The grinding process is usually completed by wet grinding in rod mills and ball mills.

Cement grinding is the final process of cement manufacturing. Its main function is to grind cement clinker (and retarders, performance adjustment materials, etc.) to a suitable particle size to form a certain particle gradation and increase its hydration area. Accelerate the hydration rate to meet the requirements of cement paste coagulation and hardening.

Cement grinding can be divided into: 1, ball mill grinding system, 2, vertical mill final powder system, 3 vertical mill-ball mill combined powder system, 4. roller press final powder system, 5, roller press -Ball mill combined grinding system, 6. Horizontal roller mill grinding system.

Thermal power plants are abbreviated as thermal power plants, which are factories that use combustibles (such as coal) as fuel to produce electricity. Large thermal power plants burn pulverized coal in order to increase the efficiency of coal combustion, so the raw coal in the coal hopper must be sent to the coal mill to be ground into pulverized coal.

It is a rotating cylindrical or tapered roller with steel balls in the roller. When working, the steel ball in the cylinder continuously hits and squeezes the coal block, and the coal block is ground into pulverized coal.

Quarrying plants are mainly places where industrial sand is prepared, such as quartz sand plants and silica sand plants. Quarry equipment, including crushers, vibrating feeders, vibrating screens, sand washing machines, belt conveyors, etc. In this process, steel balls are also frequently used materials.
