processing copper sulphide concentrates

Copper extraction WikipediaNickel smelting producing Metalpedia

All primary sulfide ores of copper sulfides and most concentrates of secondary copper sulfides being chalcocite are subjected to smelting Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution but this is a minor part of the marketIn hydrometallurgical processes nickel sulfide ores undergo flotation differential flotation if Ni/Fe ratio is too low and then smelted After producing the nickel matte further processing is done via the Sherritt Gordon process First copper is removed by adding hydrogen sulfide leaving a concentrate of only cobalt and nickel Then

Copper Sulfide Flotation Mineral Processing Metallurgycopper processing Definition History Facts

Beneficiation of Copper Sulfide by Flotation Copper due to the present world demand and price is of foremost interest to the mining industryMany new properties are either in the process of being brought into production or are being given considerationThe smelting and converting of copper sulfide concentrates result in a “blister” copper that contains 97 to 99 percent of the silver present In its pure form or as an alloy copper Cu is one of the most important metals in society The pure metal has a face centred cubic crystal structure

USA Method of roasting copper sulphide A Review on Novel Techniques for Chalcopyrite Ore Processing

A method of roasting copper iron sulphide ore concentrate or mixture wherein the ratio of sulphur values to copper values is preferably at least one to yield a calcined product for the separation and recovery of copper values by acid leaching and electrolytic deposition having at least 99 percent of its copper values soluble in dilute sulphuric acid and no more than 10 percent of the iron The intec copper process is a proven patented hydrometallurgical process for the extraction of pure copper and precious metal from sulphide concentrat The process is based on the electrolytic deposition at the cathode of LME London Metal Exchange

New breakthrough copper recovery process developedThe cuprex metal extraction process Recovering copper

Nov 09 32 The process uses a series of stirred media reactors placed in tandem with conventional stirred leach tanks to achieve its high copper recoveries from sulphide concentrat The inter stage or intra stage placement of the reactors provides the advantage of mechano chemical activation processes while adding only minimally to baseline processing The Cuprex metal extraction process produces cathode grade copper using a hydrometallurgical process based on chloride leaching of sulfide ore concentrat The process incorporates several novel steps to overcome the major problems associated with earlier chloride based processes including mild leaching conditions using ferric chloride as

First Chalcopyrite Copper Concentrate Leaching using Dissolution of copper and iron from sulfide concentrates

the region and wanted to prove up the concept of sulphide copper leaching at a commercial scale using the Albion Process TM A very cheap retrofit was undertaken on the existing oxide leach circuit and then fed a predominantly chalcopyrite/bornite concentrate 28 30 Cu Jan 25 32 Sulfide concentrates were leached for 2 h under non oxidative conditions similar to those used in the first leaching stage of HydroCopper process It was shown that copper in bornite was the most active to dissolve in the studied environment Over 85 of copper in chalcopyrite could be leached when present with other secondary copper sulfid
