12.3 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 Smelting Process Furnaces Used, By-Products, and

Sulphuric dioxide gas is created in smelting copper process and is converted sulphuric acid which is used in some of the smelting processes or sold as a by-product. Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace.

Economic Impacts of Air Emission Standards: Primary Copper

Primary copper smelting is a single part of the copper production process, which produces a single product: 99.9 percent pure copper, which can then be refined and fabricated. 2.3 MAJOR BY-PRODUCTS, CO-PRODUCTS, AND SUBSTITUTION POSSIBILITIES The copper smelting process generates slag (waste materials remaining after the copper is concentrated and

Hong Yong Sohn, Bart Blanpain, in Treatise on Process Metallurgy: Industrial Processes, 2014. 2.1.1.6.1 FeO–Fe 2 O 3 –SiO 2 Slags. It has been customary since early times in copper smelting, when acid refractories were used universally, to add SiO 2 to form a slag with the iron that has been oxidized. This is still the most common practice today, though many furnaces now use basic

What Is Copper Smelting? (with pictures)

Dec 06, 2020· The resulting copper from this step is known as blister copper. Blister copper undergoes further firing and purification to remove any remaining impurities. One of the main side effects of the copper smelting process is the production of waste. Refining copper results in three and a half times as much waste as the amount of copper produced.
