Copper Mining and Processing Resources and Glossary ,For copper sulfide ore, electrolysis is the final stage in the process of pyrometallurgy, in which anode copper slabs are hung in a large tank full of a copper based electrolyte solution and an electric current is applied, resulting in the plating of copper onto 999% pure copper cathodPreconcentration for Low Grade Copper Ore frjigThere is copper oxide and copper sulfide for copper ore with main beneficiation method of floatation separation to gain the ideal beneficiation efficiency However, many copper mines are not profitable to enrich by floatation separation And other treatment has to be taken into consideration before floatation separation Here is some preconcentration method for some low grade copper oreLeaching characteristics of copper refractory ore in ,Refractory copper ores (CROs) in central Africa contain copper minerals that are locked up in a micacious solid matrix or associated with carbonate, sulfide and phosphate mineralsEXTRACTING METALS FROM SULFIDE ORES Electrochemical ,Another example is the treatment of ores containing copper sulfide (chalcocite) and copper iron sulfide (chalcopyrite), together with molybdenum disulfide (molybdenite) The usual practice is to float both copper and molybdenum minerals in the first stage, leaving ,Copper(II) sulfide | CuS PubChemGroups of 30 32 rats were given single im injections containing 20 mg of cupric oxide (16 mg copper), cupric sulfide (133 mg copper), and cuprous sulfide (16 mg copper) into the left and the right thigh of each rat All animals were observed for up to 20 months, ,Effect of Seawater on Sulfide Ore Flotation A Review ,Effect of Seawater on Sulfide Ore Flotation A Review , At a salt concentration of 13% virtually all levitating bubbles disappear , Frothing in the flotation of copper sulfide ores in sea .123 Primary Copper SmeltingPyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrat Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining 1232 Process Description2 4 Mining produces ores with less than 1 percent copper Concentration is accomplished at the

Mineral deposit Immiscible melts | Britannica

Immiscible sulfide drops can become segregated and form immiscible magma layers in a magma chamber in the same way that cumulus layers form; then, when layers of sulfide magma cool and crystallize, the result is a deposit of ore minerals of copper, nickel, and platinum group metals in a gangue of an iron sulfide mineral Among the ore deposits .
