12.3 Primary Copper Smelting
U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams Mg 1.6 millon tons of ore produced in 1991. 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
OVERVIEW OF MINERAL PROCESSING METHODS
The following are the major processing methods involved in ore dressing/ mineral processing: 1. Performance of certain crushed ores of copper are placed into a series of tanks. As a

3 The fundamental operations of ore-dressing processes are: a the breaking apart of the associated constituents of the ore by mechanical means severance and b the separation of the severed components beneficiation into concentrate and tailing using mechanical or physical methods which do not effect substantial chemical changes. 4.
