Copper metal dissolves as cupric ions (since cuprous are generally unstable, particularly in sulfuric solution), while hydrogen ions are discharged as hydrogen gas. With an inert anode, the sulfuric acid (or sulfate ion if using a reasonably alkaline salt) is oxidized to

Copper recovery using leach/solvent extraction

Copper recovery using leach/solvent extraction

Copper recovery by L/SX/EX in 1968. In 1968 there were only two widely practiced copper leaching processes using dilute sulphuric acid. The first process, vat leaching of high grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at

12.3 Primary Copper Smelting

12.3 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.

Copper Mining and Processing Processing of Copper Ores

Copper Mining and Processing Processing of Copper Ores

Copper processing is a complicated process where it dissolves the copper from the ore. The resulting pregnant leach solution of sulfuric acid and copper sulfate is collected in a small pool. The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue. Chemical
