Lead-zinc ore slime beneficiation

The cross section of the spiral concentrator is mostly 1/4 of an ellipse, suitable for sorting mineral particles of 2 to 0.07 mm; the cross section of the spiral chute is cubic parabolic, suitable for sorting ore particles of 0.3 to 0.02 mm. The spiral concentrator and spiral chute have low investment in infrastructure, low energy consumption, simple and reliable equipment, easy operation, high enrichment ratio, and can obtain a variety of products. But the ore must be fed evenly.

Compared with other mineral processing methods, gravity separation has the advantages of large processing capacity, wide particle size range, simple equipment structure, no consumption of precious production materials, low operating costs, and no pollution. Therefore, it is widely used in the mineral processing of tungsten and tin ores. . It is also widely used in the separation of ferrous metals (iron, manganese, chromium), rare metals (tantalum, niobium, thorium, zirconium, titanium, etc.) and precious metal ores.

Maintenance and storage method of vibrating screen motor and common troubleshooting

The service life of the vibration motor determines the operating life of the entire screen. Therefore, in the normal production, we must always pay attention to whether the working state of the vibrating screen equipment is normal, whether the vibrating motor is in good working condition, timely check and solve some small abnormalities and faults, and do a good job of cleaning and maintenance, because this can greatly increase the vibration screening. Machine and vibration motor life. dewatering screens supplier Maintenance storage precautions during vibrating screen motor operation The equipment can not be completely dust-free, but also has a harsh environment and dusty conditions. The vibration motor is airless and heat-cooled. It relies on natural cooling, so it must be specially maintained. The following is the maintenance content. 1. It is necessary to pay attention to whether the vibration is abnormal during the use process; 2. Always check if the bolts used in the m

300t per hr chalcopyrite washing equipment

Chalcopyrite is a copper-iron sulfide mineral. It often contains trace amounts of gold and silver. Crystals are relatively rare and are tetrahedral-shaped, mostly irregular granular and dense massive aggregates, as well as kidney-shaped and grape-shaped aggregates. Copper yellow, often dark yellow or mottled. The streaks are black with a greenish tint. Chalcopyrite is a relatively common copper mineral, which can be formed in different environments, but it is mainly the product of hydrothermal action and contact metasomatism, and it can often form deposits of a certain scale. The origin is all over the world. In industry, it is the main raw material for copper smelting. In the field of gemology, it is rarely used alone, occasionally as a substitute for pyrite. In addition, it often participates in the composition of some colored stones, inkstones and jade. The high-efficiency spiral chalcopyrite washing machine is mainly used in the washing, grading, impurity removal, and the washing o
