Mineral processing method for various minerals

Iron : (1) ore crushing; (2) grinding process; (3) sorting technology; (4) sintering pellet technology;

Manganese : mechanical selection (including beneficiation , screening, re-election, strong magnetic separation and flotation), as well as fire method and chemical beneficiation.

Chromium : It is selected by a titanium jumping machine, a shaker, a spiral concentrator, a centrifugal concentrator and a belt chute. It is also sorted by hydraulics.

Titanium vanadium magnetite: It is carried out after magnetically selecting a magnetite concentrate through a magnetic separation process of a grinding, a coarse, a fine, and a sweep.

Copper : methods such as flotation, magnetic separation, re-election, or wet smelting.

Lead Zinc: General magnetic - floating, heavy - floating joint processing methods and the like - the floating weight - magnetic.

Aluminum : Generally used by hand.

Nickel : (1) flotation; (2) pre-removal of large-sized bedrock with low degree of differentiation and low nickel content by processes such as crushing and sieving.

Cobalt : Flotation is generally used.

Tungsten: According to the ore type tungsten ore dressing, it is divided into black tungsten and white tungsten . The ore dressing methods include hand selection, re-election, flotation, magnetic separation, and electrification.

Tin : The beneficiation method is gravity ore dressing and flotation process.

Molybdenum : mainly flotation.

Mercury : There are hand selection, re-election and flotation, among which flotation is widely used and most effective.

锑 : There are mainly methods such as hand selection, re-election, and flotation.

Platinum group: (1) Reasonable ball milling, using a suitable cyclone grading; (2) recovery rate;

Gold : Gold is extremely low in ore. To extract gold, it is necessary to crush and grind the ore and separate the gold by mineral processing. Mainly re-election and flotation.

Silver : (1) flotation method; (2) a joint process of single flotation method, float-re-election method, and flotation cyanidation method, among which flotation is the most important.

Niobium, tantalum, beryllium lithium: hand-selected method, flotation, or chemical - joint flotation method, warm election law, election law radioactive, mineral particles floating method.

锶 : The most common method used in the lapis lazuli beneficiation of the heavy stone society. The most common structural process is the jigging-shaker-based process.

Rare earth metal: Generally, magnetic separation and flotation are used to obtain about 60% of the concentrate containing rare earth oxide.

The Single Row Deep Groove Ball Bearing is the most representative structure of the rolling bearing, which is widely used. The raceway located in the inner ring and outer ring is slightly larger than the radius of the rolling ball. In addition to the radial load, it can also bear the axial load of two directions. Small friction torque, the most suitable for high speed rotation, low noise, low vibration use. Besides the way out, there is also a bearing with a steel cover, plus a rubber sealed bearing, or a ring with a retaining ring on the outer ring. Generally, the steel plate punching cage is usually used. The main application of the cage: steel plate stamping cage (wave, crown shape... Single column; S shape... Copper alloy or phenolic resin to cut the cage and synthetic resin forming cage.
