copper smelting and refinery process

Copper Smelting and Refining Process Pan Pacific

The copper concentrates are fed through the flash smelting furnace with oxygen-enriched air. In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron

12.3 Primary Copper Smelting

2015-9-10 · A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.

If a blast furnace is used, this copper is charged to a converter, where the purity is increased to about 80 to 90 percent, and then to a reverberatory furnace

Copper Smelting and Refining at Saganoseki Smelter

Abstract. In 1996 Saganoseki Smelter & Refinery integrated its two flash furnaces to one in order to reduce the operating cost and maintain the global competitiveness. And then many improvements were carried out to expand the smelting capacity. However, the copper content in concentrates had been decreased and also the anode production was limited.

Copper Refining Electrolyte and Slime Processing

Copper electro-refining (Cu-ER) is the principal method for producing >70% of high or 99.97% pure copper cathodes from 97-99% pure blister/fire refined-scrap copper anodes. While the inert and most of less soluble impurities settle as anode slime/sludge, other soluble impurities, particularly the metalloids (group VA/15 elements or Q: As, Sb and Bi) and some transition metals (Mt) co-dissolved
