copper zinc ore flotation
In the flotation of copper–zinc massive sulfide ores, the flotation properties of copper and zinc are determined by the nature and composition of the ore Selectivity between chalcopyrite andCopperZinc ores Usually chalcopyrite, sphalerite and iron sulphides are present with this type of ore Gangue minerals are typically various silicates, carbonates, and often talc the latter which presents flotation challenges The flotation separation and recovery approach is quite similar to the PbZn sulphide separation process Sphalerite is depressed with zinc sulphate addition toCopperZinc ores Danafloat
CopperLeadZinc ores The CuPbZn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage In this case, as a general rule because both copper and lead minerals tend to float well, these are14/04/2016· The Problem with separating Copper from Zinc by flotation The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high The method of oreChalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation
In the flotation of copper–zinc massive sulfide ores, the flotation properties of copper and zinc are determined by the nature and composition of the ore Selectivity between chalcopyrite and29/09/2021· Flotation method is mostly used in the separation of nonferrous metal (copper, lead, zinc, etc) ores, especially for finegrained, intergrowth and complex ores such as copperleadzinc ore The flotation of copper, lead, and zinc generally adopts the differential flotation process, which means separate the copper concentrate, lead concentrate, zinc concentrate and tailings according to theThe Flotation Reagent Selection in Copper, Zinc and Lead
and commissioned in November 2008 During the initial stages of sulphide operation, high copper (Cu)low zinc (Zn) ore was fed to the plant Marketable copper concentrate at 9195% recovery was produced utilizing a highpH bulk sulphide rougher flotation and 2 cleaning stages Because of increased levels of ZnThe known method of flotation of copperzinc ores with the use of regulators flotationproduct of the interaction of alkali cellulose, monochloracetic acid or its sodium salt, and sodium sulfate [1] The method is characterized by use of scarce reagents and does not always produce high minerals) Closest to the present invention is a method of flotation of sulfide copperzinc ores, includingMethod of flotation of sulfide copperzinc ores
It is reported that more than 90% of nonferrous metal ores (copper, lead, zinc, etc) adopt flotation process, especially for those with fine grain and complex symbiosis Flotation process can achieve ideal separation effect, and separately recover lowgrade ore then enrich multiple highgrade concentrates Different ore properties means different flotation process According to theSulphide ores are the major sources of base metals like Copper, Lead, Zinc, Nickel and Cobalt Beneficiation of these base metal sulphide minerals is predominantl y through the froth flotation(PDF) A Review of the Flotation of Copper Minerals

Chapter 15: Flotation of CopperLeadZinc Ores 151 GENERAL OVERVIEW OF THE ORIGIN OF COPPERLEADZINC ORES The 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 metals29/09/2021· Flotation method is mostly used in the separation of nonferrous metal (copper, lead, zinc, etc) ores, especially for finegrained, intergrowth and complex ores such as copperleadzinc ore The flotation of copper, lead, and zinc generally adopts the differential flotation process, which means separate the copper concentrate, lead concentrate, zinc concentrate and tailings according to theThe Flotation Reagent Selection in Copper, Zinc and Lead
