AN INTRODUCTION TO COPPER EXTRACTION
AN INTRODUCTION TO COPPER EXTRACTION

2.2 OVERVIEW OF COPPER EXTRACTION The copper extraction process begins at an open cut mine where Copper Ore is blasted and removed via Excavators and Tip Trucks. The ore is fed to a Crusher where it is broken down to a specified maximum size and passed through to a conveyor. When the crushed ore falls onto the

Solvometallurgical process for extraction of copper from

Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals chalcopyrite, bornite, chalcocite and digenite was developed by usinganic lixiviant FeCl 3 as oxidizing agent and ethylene glycol EGanic solvent.

Copper extraction is distinctly profitable when the selling price of copper is above $6/kg. It is unprofitable for some operations when the selling price falls below $3/kg. At the former price, the industry tends to expand. At the latter, it begins to contract. The selling price of copper in mid 2011 was $9/kg.

Copper extraction

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated concentrated.

7/6/2021· The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite C u F e S 2 are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite also known as copper pyrites and similar sulfide ores aremonest ores of copper.
