not to be missed mineral ball mill for gold mining

how to replace the ball mill liner?

After successfully purchasing a ball mill, it is necessary to carry out daily maintenance and servicing of the ball mill, and the replacement of the ball mill liner is one of the essential maintenance work.

Ball mill is indispensable equipment in the beneficiation operation because it is necessary to grind the ore to suitable particle size to extract high-grade concentrate from the ore. Thus, choosing a suitable ball mill, from the pre-purchase consultation to the smooth installation of the ball mill, the test run, takes a lot of time and effort. Moreover, the price of ball mills is relatively expensive among many mineral processing equipment. Therefore, after successfully purchasing a ball mill, it is necessary to carry out daily maintenance and servicing of the ball mill, and the replacement of the ball mill liner is one of the essential maintenance work.

Under normal conditions, if it is not improperly operated and maintained, the ball mill will not be easily damaged. Of course, the ball mill will work for a long time, and the barrel and the lining of the ball mill will also wear. When the lining wear depth is serious, which will seriously affect the efficiency and safe operation of the ball mill.

At this time, it is necessary to replace the new ball mill liner. The ball mill liner is intended to protect the barrel of the ball mill in order to reduce and avoid direct impact and friction of the body and abrasive minerals on the barrel of the ball mill. The form of the ball mill liner is not uniform. Different types of liners can be used to adjust the movement state of the grinding body, improve the efficiency of the grinding operation of the ball mill, and reduce the consumption of metal. Therefore, the protective effect of the ball mill liner on the ball mill cannot be ignored. Xinhai mining companys dressing experts with more than 20 years of mineral processing experience believe that when the wear of the ball mill liner is very serious, replacing the ball mill liner is an effective method to solve the problem of liner wear.

The replacement of the ball mill liner is a very cumbersome and technically high-quality work. In addition to the above-mentioned replacement techniques, its particularly necessary and important to guarantee the personal safety of operation workers. Correct ball mill liner replacement operation can improve the use time of the ball mill and ensure the safe operation of the ball mill.

grinding - mineral processing

The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.

In order to separate the concentrate from the ore, the ore should be ground fine enough to release the target mineral from the non-mineral grains. The degree of grinding required for this depends on the size of the mineral particles in the ore. A laboratory-scale flotation test is usually required on materials of different particle sizes to determine the grinding particle size required to release the target minerals.The fineness of the ore particles produced by grinding is crucial to recover the minerals by flotation. The most common grinding machines are semi-automatic (SAG) and automatic (AG) mills and ball mills.

Determining an optimal grinding size can maximize the recovery of target minerals in the subsequent flotation process.The grinding size is too large, and some ore particles and non-ore particles cannot be separated, thus preventing their flotation. If the particle size is too fine, the bubbles that rise during the flotation will push the very fine ore-containing particles away, preventing them from contacting the bubbles, thereby reducing their ability to be recovered into the concentrate.In addition, extremely fine rock and iron sulfide particles may agglomerate with extremely fine sulfide ore particles, preventing the ore particles from floating.

According to the test, the particles usually need to be ground to a diameter of about 100 mm to release minerals from each other. When the particles are less than about 10 mm, this is not conducive to the flotation effect.Grinding operations are very power-hungry, which is another reason to avoid excessive grinding.

The crushed products are ground in SAG or AG mills. The self-grinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.A large vibrating screen is used to sieve the ground products to separate the oversized particles. A small cone crusher to recover the oversized material, and then sent them return to the SAG or AG mill for re-grinding. The correct size material is sent to the ball mill for final grinding.

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.Grinding is always carried out under wet conditions, with about 70% solid mixture in water.This procedure maximizes ore production and minimizes power consumption.

wet pan mill gold mining - crushers, ball mills and flotation cells for mining and mineral beneficiation

CGN wet pan mill gold mining also called wet gold grinding machine is used for amalgamation gold extraction of sulfide-free gold mines and is suitable for operations in field areas without power supply by equipped with a diesel generator.

1. The Application of Wet Pan Mill gold mining CGN wet pan mill also called wet gold grinding machine is used for amalgamation gold extraction of sulfide-free gold mines and is suitable for operations in field areas without power supply by equipped with a diesel generator. This machine, which has functions of crusher and ball mill, can crush the ores once for all in the purpose of gold extraction in amalgamation method.

3.Working principle of Wet Pan Mill The diesel generator is responsible for power supply in operation. The reducer and the interlocked main shaft are driven via the belt to run the grinding wheel and grind the ores. When crushed to 0.05-1mm, the ores are added for mercury cycle operations. When extracting mercury cream, the machine should be stopped.

4. Principle of Amalgamation for gold Amalgamation method is to extract gold particles in the ores. When crushed to 0.05-1mm grain size or more, most of the gold particles can be separated and drift in the water. The gold particles in 0.05mm-1mm grain size are surrounded by mercury, and compound reaction occurs to generate mercury paste of AuHg2, Au2Hg and Au3Hg, which is also known as gold amalgam. Since gold and silver are usually associated, there is silver in the mercury paste in addition to gold, and is separated from other metallic minerals. The amalgamation process takes place under the infiltration effect of water, gold and mercury. The recovery of gold depends on grinding size, cleanliness of gold particle, ore pulp concentration, temperature, and pH value. To save the consumption of mercury, the ores are usually ground to 0.05-1mm before added to mercury. The mercury per ton of ore depends on the grade of raw ores. 2% of lime should be added to reduce the viscosity of the ore pulp, the pH value of the ore pulp should be adjusted to PH8-9, and the concentration should be in 30%-40% for amalgamation operations. After amalgamation, water is added to dilute the ore pulp for mercury deposition and accumulation. The mercury paste can be recycled after the gold particles treated and removed.

6.Installation, Usage and Maintenance 1. The machine should be installed on a concrete foundation, placed on level and the anchor bolts should be tightened. 2. Operation steps: Shift the clutch handle to ON position to start the diesel generator. Engage the clutch to drive the host when the operation is normal, and feed materials and water for operation. Disconnect the clutch to stop the machine before cleaning up the mercury paste. 3. Add water, engine oil and diesel oil to the diesel generator on regular basis. See the instructions for details. Lubricate the clutch and upper bearing cover once and add engine oil into reducer once every 30 days. 4. The power section should be kept from sunlight and rain, and ore pulp infiltration to be avoided in operation.

ball mill used in minerals processing plant | prominer (shanghai) mining technology co.,ltd

This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

Compared with grid type ball mill, overflow type ball mill can grind materials finer even though its grinding time is usually longer. So it can make finer particle products. Hence the grid type ball mill is mainly used for primary stage of grinding while overflow type ball mill is mainly used for the secondary grinding.

Ball mill Advantages: 1Jack-up device, easy maintenance; 2The hydrostatic and hydrodynamic bearings ensure the smooth operation; 3Low speed transmission is easy for starting and maintenance; 4The oil-mist lubrication device guarantees reliable performance of bearings; 5The air clutch adopts the flexible start-up model./5According to the customer demand, manganese steel liner and wear-resistant rubber liner can be customized with good wear resistance, long service life and easy maintenance.

The grinding system uses either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of materials is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer ones and sent back for further grinding.

Prominer has been devoted to mineral processing industry for decades and specializes in mineral upgrading and deep processing. With expertise in the fields of mineral project development, mining, test study, engineering, technological processing.

golden minerals announces expansion drilling at rodeo gold mine

GOLDEN, Colo., March 21, 2021 (GLOBE NEWSWIRE) -- Golden Minerals Company (NYSE American and TSX: AUMN) (Golden Minerals, Golden or the Company) is pleased to announce it has begun an exploration drilling program at its operating Rodeo gold mine (Durango State, Mexico) aimed at expanding the resource.

The program will encompass approximately 2,000 meters of exploration drilling at selected near-surface targets located immediately adjacent to the current pit. The program has the potential to extend the life of the Rodeo mine well beyond the currently estimated life of around 2.5 years. Results should begin to be available within the next several months and any newly-added resources will be incorporated into the Companys production plans.

Recent mining activities at the Rodeo open pit gold mine have revealed very interesting expansion targets that, in my opinion, could potentially extend Rodeos life by a meaningful amount, said Warren Rehn, President and Chief Executive Officer of the Company. Based on our previous drilling, we thought the higher-grade mineralization was closed off to the north by two drill holes; however, it is now apparent that those drill holes likely missed the main mineralized zone. Our more complete understanding of the geology of the deposit based on the new open pit exposures lead us directly to the current drill targets.

The Company began mining at Rodeo in late December 2020 and announced it had begun processing at a rate of approximately 200 tonnes per day (tpd) in mid-January 2021, roughly two weeks ahead of schedule and on budget. Rodeos first gold pour took place at the end of January 2021. At that time, Golden announced it would be ramping up processing to the full run rate of around 450 tpd, which was anticipated to occur by the end of the first quarter 2021 when installation of a regrind ball mill was complete and brought online. These activities remain on track and are anticipated to occur by March 31, 2021.

The Company has continued to pour gold on a weekly basis, if not more frequently, as planned and has exported and sold its first batch of gold-silver bars. The Company is on track to complete its forecasted annual production of between 12,000 and 14,000 ounces of gold in 2021.

About Golden Minerals Golden Minerals is a Delaware corporation based in Golden, Colorado. The Company is primarily focused on advancing its Rodeo and Velardea properties in Mexico and, through partner-funded exploration, its El Quevar silver property in Argentina, as well as acquiring and advancing mining properties in Mexico, Argentina, and Nevada.

Forward-Looking Statements This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended, and applicable Canadian securities legislation, including statements regarding expectations surrounding the extended life of mine at Rodeo; timing of results for the current exploration drilling program at Rodeo; timing of processing Rodeo material and expected run rates; and expectations regarding annual production at Rodeo. These statements are subject to risks and uncertainties, including the reasonability of the economic assumptions at the basis of the Rodeo Preliminary Economic Assessment and technical report and the other economic projections of the Rodeo mine; changes in interpretations of geological, geostatistical, metallurgical, mining or processing information; interpretations of the information resulting from exploration, analysis or mining and processing experience; fluctuations in exchange rates and changes in political conditions, tax, royalty, environmental or other laws in Mexico; fluctuations in silver or gold prices; and the timing duration and overall impact of the COVID-19 pandemic, including the potential future re-suspension of non-essential activities in Mexico, including mining. Golden Minerals assumes no obligation to update this information.
