(1) Aminodithioformate. It is a compound in which diethylamine (or dibutylamine) reacts with carbon disulfide and sodium hydroxide: C 2 H 5 S \ ∥ N — C        / \      C 2 H 5 SNa (sodium diethylaminodithioformate) C 4 H 4 S \ ∥ N — C / \ C 4 H 9 SNa (dibutylaminodithioformate) Ethylsulfide is a white powder. Due to the small amount of xanthate produced during the reaction, industrial products are often pale yellow. Soluble in water, easy to decompose in acidic medium. Diethyldithiocarbamate can also be the case with the formation of insoluble precipitate heavy metal, stronger than the xanthate collector capacity. It is the other lead from the ore, collecting capability strong brass ore pyrite collector of weak, good selectivity, high flotation rate, with less than xanthate, strong coarse-grained sulfide ore of the living body Collective. When it is used for the separation of copper-lead sulfide ore, it can obtain better sorting effect than xanthate.

(2) Thiazolyl ester. Its general formula is RNCSSR ËŠ, which is the reaction product of sulfur nitrogen and acrylonitrile. Esters such as diethyl dithiocarbamate eyes [(C 2 H 5) 2 NCSSCH 2 CN] tan oily liquid, slightly fishy, insoluble in water, soluble in organic solvents, there is foaming. When flotation of copper sulfide ore, sulphur nitrogen ester can replace butyl xanthate and pine oil, but its solidification is low, and it is necessary to take insulation measures when adding.
