Cu-Pb-Zn, Copper-Lead-Zinc Ores, Copper Lead Zinc
Xinhai separates two useful minerals that with similar floatability into the mixed concentrate, and then floats each concentrate. That is, copper sulphide and lead ore with similar floatability are selected as mixed concentrate, and copper and lead is separated. Then the tailings were reactivated to separate the zinc concentrate.

New Non-Cyanide Technology for Processing Massive
This paper presents the results of studies on the development of an efficient non-cyanide technology for processing massive, finely disseminated, copper-zinc ores of the Urals deposits. Copper is mainly represented by chalcopyrite and zinc - by sphalerite. The main ore mineral is pyrite, with its content in ores varying from 50 to 80 per cent.
