How to Concentrate Copper Science

Dec 19 2003 P orphyry copper deposits supply nearly 60 of the worlds copper 11 They form as magmas in the upper crust cool crystallize and exsolve metalbearing hydrothermal fluids that precipitate copper sulfide minerals The deposits have been studied for over a century revealing a strikingly constant spatial and temporal relationship between copperbearing hydrothermal veins and

Concentration Of Ores Questions and Answers Toppr

In some sulphide ores of copper zinc and lead the concentration is brought by froth flotation processIn this method the advantage is taken of the preferential wetting of the ore by an oil The finely ground ore is taken in a tank containing water and 1 of pine oil or turpentine oil Collectors e g pine oils fatty acids xanthates etc enhance nonwettability of the mineral

Concentrating Resolution Copper

Concentrating In the second step of the production process we convert the ore from a lowgrade material into a concentrate of highgrade copper inside the Concentrator Complex The technique all begins with a wet grinding process that turns the crushed ore into a slurry and transports it to flotation cells When mixed with water reagents and air the copper minerals produce a bubbly froth

Copper Ore Processing Methods

Apr 11 2017 Copper Ore Processing Methods The four major steps in the production of marketable copper are mining concentrating smelting and refining In a few instances however leaching takes the place of concentrating smelting and refining At present although considerable leaching and directsmelting ores are produced the bulk of the copper ore mined is concentrated
