Flotation of CopperLeadZinc Ores ResearchGate

This paper reports the results of flotation tests conducted with a copperleadzinc sulphide ore The major sulphide minerals in the ore are chalcopyrite, galena, sphalerite, marmatite and pyriteTherefore the standard CuPbZn flotation practice involves an initial flotation of a CuPb bulk concentrate followed by two parallel circuit stages of copperlead separation and separate zinc flotation from the bulk flotation tails As described in the leadzinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyriteCopperLeadZinc ores DanafloatThe copperleadzinc ores have an origin similar to copperzinc and leadzinc ores, the exception being those ores that contain copper, lead and zinc as the principal economic minerals In addition, some of these ores contain significant amounts of precious metals and, more rarely, cobalt and nickelChapter 15: Flotation of CopperLeadZinc Ores

How to Process Copper Lead Zinc Ore with Gold and Silver

The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements A further separation of the leadcopper into their respective products by flotation is often economically advantageous if the crude ore contains 08% copperCommon Questions About CuPbZn Processing Technology Among the separation of copper, lead and zinc ores, copper ore is relatively easy to be sorted But in many cases, copper ore is symbiotic with leadzinc ore, and these three kinds of ores can be studied together inLead Zinc, Copper Lead Zinc, Copper Lead Zinc FlotationThe Qixia orebody is a complex lead–zinc sulfide system with pyrite gangue and minor amounts of copper In order to improve the flotation results, laboratory scale flotation testing of oreFlotation of LeadZinc Ores ResearchGate
