AUA chemical patent summaryIron sulfide (iron pyrites) is typically, in copper sulfide bearing ores being concentrated by the froth flotation process, an undesirable element in the final ore concentrate In the first place, it is generally deleterious to the equipment employed in the reduction of the copper sulfide ores to copper and adds significantly to the air pollution problems at the smelter Accordingly, it is FLOTATION OF COPPER SULFIDE ORES STEPHAN CHEM CO,US30/12/2017 From a flotation feed assaying 27% Cu, a copper concentrate assaying about 235% Cu at a recovery of 915% was obtained in only one roughing and one cleaning stages EFFECT OF THE COLLECTOR DOSAGE(PDF) Flotation of an Oxidized Copper Sulfide Ore
Copper Sulfide an overview ScienceDirect Topics
The concentrates of copper from sulfides ores are generally performed by flotation and then processed by pyrometallurgic or hydrometallurgic routes to extract copper from the concentrates Although the pyrometallurgic process is the major route to produce copper, more and more attention has been paid to hydrometallurgic and bioleaching processing routes due to their 30/12/2017 Copper ores are known to contain copper i ron sulfide, copper sulfide minerals or both Examples of such minerals include chalcopyrite (CuFeS2), bornite (Cu5FeS4), chalcocite (Cu2S) and covellite (PDF) Flotation of an Oxidized Copper Sulfide OreAUA chemical patent summaryFlotation of upper zone copper sulfide ores Patent AU
Current Situation of Flotation Process and Reagents of Cu
Flotation Collector for Copper Sulfide Ore Xanthate Xanthate which contains xanthate, xanthate esters and xanthate anionic collectors are effective collectors for sulfide ores It is widely used as flotation collector for sulfide ores because it is cheap and easy to manufacture The stability of xanthate is poor When the xanthate meeting heat, water and acid, it will decompose The A sequential flotation process for the recovery of highgrade concentrates of copper, lead and cobaltnickel from sulfide ores is provided A primary grind ore pulp is conditioned with SO 2 as H 2 SO 3 under intense aeration, and the conditioned pulp subjected to sequential flotation, with regrinding and conditioning of a copper rougher concentrate obtained in the first flotation USA Sequential flotation of sulfide ores Google A method for the flotation of nickel and copper sulphide minerals from talcose bearing ores using an alkaline circuit in which at least one of the alkaline reagents is soda ash or ammonium hydroxide and following conditioning of the pulp with a collecting agent of the xanthate family to activate the nickel and copper sulphide materials, the pulp is conditioned with a flocculating USA Flotation of copper and nickel sulfides from
