Abstract

The invention discloses a beneficiation method for copper-lead sulphide ore, and belongs to the technical field of beneficiation. The method comprises raw ore grinding, copper-lead mixing flotation and copper-lead separation. Copper-lead mixing flotation comprises primary copper-lead roughing, tertiary copper-lead fine selecting and secondary copper-lead scavenging. Copper-lead separation comprises primary copper roughing, tertiary copper fine selecting and secondary copper scavenging. Lime, calcium hypochlorite, zinc sulfate, sodium sulfite, sodium sulphide, dimethyl dicarbonate, sodium pyrophosphate, sodium citrate, ethionine ester, ethyl thio carbamate, sodium n-butylxanthate, aniline aerofloat, diphenyl amino phosphorodithioic acid and sodium carbonate are added in the copper-lead roughing and copper-lead scavenging processes. Lime, water glass, sodium phosphate starch, carboxymethyl starch, phthalic acid, thiosalicylic acid, ethionine ester and sodium ethylxanthate are added in the copper roughing and copper scavenging processes. The beneficiation method solves the problem that in the process of beneficiation of the copper-lead sulphide ore through a traditional flotation method, the copper and lead recycling rate is low.

Description

technical field

[0001] The invention relates to the technical field of mineral processing, in particular to a method for selecting copper-lead sulfide ore. Background technique

[0002] The separation of copper and lead is one of the main problems in the beneficiation of complex sulfide ores. The use of cyanide to suppress copper and float lead or dichromate to suppress lead and float copper are two typical copper-lead separation schemes commonly used in production practice. However, both cyanide and dichromate are highly toxic agents, which will cause damage to the environment; in addition, there are disadvantages of low recovery of copper and lead in the selection process of copper-lead sulfide ore by traditional flotation; therefore , it is necessary to provide a method for selecting copper-lead sulfide ore to solve the above problems.
