Copper Production: How Is Copper Made?

Manufacturing Process of Copper. Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.

Extracting Copper from Ore: A Step-by-Step Guide

Heap Leaching. Heap leaching is a method for extracting copper from ore by piling it into an outdoor pile, then sprinkling acid over the heap. The acid reacts with the copper sulfide in the ore and slowly dissolves it away as a solution of sulfuric acid and copper sulfate. This process can take up to several months, depending on the size of …

Copper Extraction and Purification | ChemKey

Copper can be extracted from non-sulfide 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 sulfuric acid to produce a very dilute copper (II) sulfate solution. Concentration of the copper (II) sulfate solution by solvent extraction.

Solvent Extraction

LIX ® Reagents . BASF's copper extraction reagents are based on oxime chemical structures. These reagents give up a proton (hydrogen cation) and exchange it for the Cu +2 ion. The structure of the resultant complex, called a chelate, is very specific to copper at a pH <2.5 and will reject every other metal except from a small amount of iron.
