Advantages of exteraction of copper

from ore to finished product copper4. beneficiation of copper ore. the next step in processing is called beneficiation. this is the first step in concentrating the copper into a more useable form. 5. smelting and extraction. the next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.extracting metals with charcoal experiment rsc educationexperiment 2 copper(ii) oxide. transfer one spatula measure of copper(ii) oxide to a hard glass test tube. carefully add one spatula of charcoal powder on top of the copper oxide without any mixing. strongly heat these two layers for five minutes in a bunsen flame. allow to coolprocess of the extraction of coppercopper extraction in particular is of great interest in archeometallurgical studies since it dominated other metals in mesopotamia from the early chalcolithic until the midtolate sixth century bc.
