More than two metal-rich sulfide ore flotation process should be chosen directly. For polymetallic lean ore, it is advisable to use a mixed or partially mixed flotation process. When there are differences in the floatability of some minerals in the three polymetallic sulphide ore, it is advisable to adopt a floatable process. 4 polymetallic sulphide ore with different ore floatability, low grade ore, fine mineral size, relatively difficult to select or high oxidation rate, consider branch flotation or equal float and branch float Selected joint process. 5 ore gold, silver, platinum, lead and other heavy minerals and ores easy to produce too brittle heavy mineral grinding in grinding, the flash flotation process may be employed. When the quality of 6 concentrates is high and the useful minerals are finely embedded, the multi-stage grinding process of concentrate should be used. 7 ore with high ore grade and good floatability. When the quality requirements of concentrates are not strict, it is advisable to use rough selection to produce the final concentrate and 1 to 2 sweeps. For ore with low grade ore and high quality of concentrate, multiple selected processes should be used. The return point of the 8 medium mines shall be determined by the test, and the design may be appropriately adjusted according to the quality requirements of the concentrate and the nature of the medium ore. 9 contains large amounts of ore flotation agent, slime and a large amount of hard mineral material, it should be used in the mine separate processes. Epichlorohydrin is a volatile and flammable, clear, colorless, liquid, chlorinated cyclic ether with an irritating, chloroform-like odor that emits toxic fumes of hydrochloric acid and other chlorinated compounds when heated to decomposition.

Epichlorohydrin is used in the manufacture of epoxy resins, synthetic glycerin and elastomers. Exposure to epichlorohydrin irritates the eyes, skin and respiratory tract, and can cause chemical pneumonitis, pulmonary edema, and renal lesions. This substance also affects the blood. Epichlorohydrin is reasonably anticipated to be a human carcinogen and may be associated with an increased risk of developing respiratory cancer. (NCI05)
Non-ferrous metal concentrator design process - flotation
A sulphide ore with finely divided fine particles should be selected for a period of flotation. For the sulfide ore with uneven coarse and fine grain, a multi-stage flotation process should be used.
Epichlorohydrin is an epoxide that is 1,2-epoxypropene in which one of the methyl hydrogens is substituted by chlorine. It is an organochlorine compound and an epoxide. It derives from a 1,2-epoxypropane.Mainly for the production of epoxy resin, synthetic glycerine, chlorohydrin rubber and glycidyl ether and other products, can also be used for synthesis of nitroglycerine explosive, glass fiber reinforced plastic, electric insulation, surface active agent, pharmaceutical, pesticide, coating, ion exchange resin, a variety of products such as plasticizer, used for cellulose ester, resin, cellulose ether solvents, used in the production of chemical stabilizer, dyes and water treatment agent, etc.
