Chapter 6 Copper Production Technology

Chapter 6 Copper Production Technology

ized in all phases of copper production. Both ma-chine and human productivity have increased dramatically. This chapter briefly describes the technology for producing copper, from exploration, through mining and milling, to smelting and refining or solvent extraction and electrowinning. The chap-ter begins with an overview of the history of cop-

BACKGROUND REPORT SECONDARY COPPER

BACKGROUND REPORT SECONDARY COPPER

Leaching is used to recover copper from slime, a byproduct of electrolytic refining. In this process, sulfuric acid is circulated through the slime in a pressure filter. Copper dissolves in the acid to form a solution of copper sulfate CuSO 4, which can then be either mixed with the

123 Primary Copper Smelting

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4

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.

Environmental Guidelines for Copper Smelting

Environmental Guidelines for Copper Smelting

The smelting process typically produces less than three tons of solid waste per ton of copper produced. Pollution Prevention and Control Process gas streams containing SO2 are processed to produce sulfuric acid, liquid sulfur dioxide, or sulfur. The smelting furnace will generate process gas streams with SO2 concentrations ranging 0.5-80 percent

Current Distribution in Modern Copper Refining

The copper industry was based essentially on the use of a copper starter sheet as the substrate for the refined copper deposition. In the 1970s operating current densities with this technology were typically around 220-250 amps per square metre. There was a clear recognition that the maintenance of
