Copper Mining Factshow Is Copper Extracted

copper extraction and purification - chemguide,copper can be extracted from non-sulphide ores by a different process involving three separate stages: reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(ii) sulphate solution. concentration of the copper(ii) sulphate solution by solvent extraction..copper mining and processing: processing copper ores,when it is economically feasible, a mine may extract both types of copper minerals; when it is not possible, mines will only process either the copper oxides or the copper sulfides. the first steps of copper processing are the same for both ores: mining and transporting..

Purification Of Copper By Electrolysis Metal Extraction

purification of copper by electrolysis metal extraction

copper is extracted from its ores by chemical processes that involve heat or electricity (roasting ores in a smelter–furnace and purification by electrolysis – all the details below). because of its position in the reactivity series of metals, less reactive copper can be extracted using carbon in a smelting furnace. copper is well below carbon (less reactive) and so can be displaced by carbon from its compounds eg
