antimony ore beneficiation plant

Metallic antimony is an extremely brittle metal of a flaky, crystalline texture. It is bluish white and has a metallic lustre. It is not acted on by air at room temperature, but burns brilliantly when heated with the formation of white fumes. It is a poor conductor of heat and electricity.Antimony and its compounds are toxic. It is found mostly with other minerals and in stibnite.

Antimony Concentrate

Cathay is one of the leading antimony chemicals producers in China, we supply antimony concentrate solutions for our customers.The Antimony Concentrate of antimony from ores depends on the quality of the ore, which is usually a sulfide. The sulfide is converted to an oxide and advantage is often taken of the volatility of antimony(III) oxide, which is recovered from roasting.This material is often used directly for the main applications, impurities being arsenic and sulfide. Antimony can be isolated from its ore by a reduction with scrap iron.

Lead zinc ore beneficiation

Lead zinc ore in lead-zinc ore is extracted from the earlier one of the metal. Lead and zinc are widely used in electrical industry, mechanical industry, military industry, metallurgy industry, chemical industry, light industry and pharmaceutical industry and other fields. In addition, lead metal in the nuclear industry, oil industry and other departments have more uses.Lead & Zinc Ore Beneficiation Plant

Lead zinc ore beneficiation methods

Lead in lead-zinc mine in 11 species of industrial minerals, industrial minerals zinc and six species, with galena, sphalerite, the most important. The chemical formula of galena PbS, the crystal structure of equiaxed crystal and sulfur ions to cubic closest packing, lead ions in all octahedral filling the gap. Fresh galena surface is hydrophobic, is not easily oxidized galena flotation, surface oxidation can be reduced float.

Xanthate or black drug is galena typical collector, xanthate on galena surface chemical adsorption, Baiyao and B-N-collector is also commonly used, including ammonium small black galena selective drug arrest income effect. Dichromate is an effective inhibitor of galena, but was activated galena Cu2 +, the inhibition effect decreased. Inhibited by dichromate had galena, it is difficult activation, use hydrochloric acid or in acid medium, after treatment with sodium chloride can be activated. Cyanide did not inhibit its flotation, sodium sulfide galena floatability of very sensitive, the presence of excess sulfur ions inhibit the flotation of galena; sulfur dioxide, sulfurous acid and its salts, lime, zinc sulfate or with other agents can inhibit the flotation of galena.
