From Ore to Finished Product Copper
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze copper-tin alloy about 3000 BC, was the first engineering material known to man.

COPPER ELECTROWINNING THEORETICAL AND PRACTICAL DESIGN 213 Introduction The electrowinning of copper ions derived from leaching, or solvent extraction is a significant contributor to the global copper commodity supply. The process of electrolysis for copper was first developed in the late 19th century and despite numerous advancements in ...
Electrorefining of Copper
Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage either via electrorefining from impure anodes or electrowinning from leach or solvent-extraction liquors.

Extraction Of Copper Mining Concentration Smelting
The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers.

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. see figure 6-2. About 2500 B. C., copper was combined with tin to make bronzean alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
