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. 12.3.2 Process Description2-4

Recycling of Copper

Secondary copper can be used for the manufacture of these materials, though still within stipulated quality limits for impurities. Where scrap copper is associated with other materials, for example after having been tinned or soldered, it will frequently be more economic to take advantage of such contamination than try to remove it by refining.

Copper Scrap - an overview ScienceDirect Topics

Recycling of copper is based on a large variety of raw materials, ranging from low-grade copper scrap containing only a few percent Cu to very high-grade copper as well as pure copper close to 100% Cu (Table 7.1). Thus there are several options for recycling processes, within both primary plants and secondary plants treating only scrap material.

Copper - Essential Chemical Industry

Secondary production. Copper and alloys with a high copper content are recycled to obtain pure copper. The metals are heated with oxygen-enriched air, which oxidizes most of the metals, but not the copper or any precious metals, forming a slag that can be removed. The Isasmelt process described above is often used for secondary copper production.
