    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

    The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Iron in Chalcopyrite is removed as Iron silicate slag. Most of the sulfur in Chalcopyrite turns into Sulphur dioxide (SO2).

    Extracting copper from other ores. Copper can be extracted from nonsulphide 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.

    Jan 18, 20190183;32;Extraction of Copper. Chalcopyrite (CuFeS 2) is the commonest copper ore. Copper is mainly extracted from the sulphide ore (Cu 2 S) by the self reduction process. The ores are often low grade (0.5% Cu) and require concentration (up to 1520% Cu). The process contains the following steps.
