Process for smelting nickel - Toyo Engineering Corporation- nickel smelting and refining process ,The present invention concerns a process for smelting nickel which comprises treating nickel-containing material with a reducing gas to reduce the nickel component contained in the nickel-containing mCopper SmeltingThe smelting process typically produces less than 3 tons of solid12.3 Primary Copper Smelting,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.Copper, Lead and Zinc Smelting and Refining,Copper, Lead and Zinc Smelting and Refining,bismuth, iron, lead, nickel, selenium, sulphur and zinc,Table 2 lists environmental pollutants for various steps in lead smelting and refining.
