How to select antimony ore reselection method in actual processing! [Jiangxi Ganzhou Shicheng mine e

1, what is antimony ore!

Antimony ores can be divided into 3 types: oxidized ore, mixed ore and primary ore, and the standard is based on the oxidation rate of antimony (%): the oxidized ore is >50%, the mixed ore is from 30% to 50%, and the original ore is <30%. The industrial type of antimony ore, according to the characteristics of the material composition of antimony deposits in China, some of the single antimony ore deposits, more is a multi component associated deposits, some antimony and gold, mercury, tungsten, etc.. Therefore, there are several types of antimony ores, such as antimony, antimony, antimony, mercury, antimony, tungsten and antimony.

2, heavy medium separation

In the heavy medium separation is a new technique of gravity. In 1975, Guangxi Dachang Changpo tin concentrator, 1966 China plant completed the heavy medium separation of antimony ores. On the basis of gravity is not the same in the mineral medium flow, has not the same settlement or motion velocity discontinuity sorting approach, including jigging and tabling (straight activities) (bevel activities) and centrifugal separation (rotation) and heavy medium separation, namely ore in heavy suspension continuous sorting. Stibnite density is 4.26g/cm3, the gangue density is 2.6 ~ 2.65g/cm3, the drop ratio is 2.19 to 2.26, according to easy ore density sorting. Huang Tihua (5.2g/cm3), red antimony (7.5g/cm3), valentinite (5.57 g/cm3), and gangue falling ratios were 2.55 ~ 2.63, 3.93 ~ 4.06 and 2.76 ~ 2.86, the three antimony ore is very simple to according to the density separation of ore. Only the water antimony calcium ore density of 3.14 g/cm3, the ratio of its only fall to 1.29, attributed to the more difficult to separate ore.

3, what gravity ore dressing?

The cost is usually higher than the low gravity flotation, and can be used as a pre process in flotation used to remove a lot of gangue. Because of the difficulty of antimony oxide ore flotation, at this stage still from gravity.
