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.

obsolete at U.S. primary copper smelting facilities. The traditional reverberatory smelting process as it exists in the U.S. involves the charging of concentrate and a siliceous flux to an externally fired smelting furnace maintained at a temperature as high as 1500 EC (2730 EF). Impurities in the charge oxidize with the flux to form a

Copper Smelting an overview ScienceDirect Topics

Copper smeltingplants separate elemental copper from copper concentrates through multiple sulphide oxidizing stages. The considered smelting process includes a continuously functioning flash smelting furnace (FSF) and several Pierce-Smith converters operated in batches. Automating scheduling provides advisory information to operators.

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

Copper processing Roasting, smelting, and converting

Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or

Copper Compendium, Part 3: Primary Copper Production

Copper smelting is a pyrometallurgical process. Copper is also extracted from low grade ores by a two-stage hydrometallurgical technique known as the SX‐EW Process, solvent extraction (SX) followed by electrowinning (EW).

for copper production. The traditional process is based on roasting, smelting in reverbatory fur-naces (or electric furnaces for more complex ores), producing matte (copper-iron sulfide), and con-verting for production of blister copper, which is further refined to cathode copper. This route for production of cathode copper requires large

2.1 Process description 2.1.1 Primary copper production The traditional pyrometallurgical copper smelting process is illustrated in Figure 3.1 (EPA, 1993). Typically, the blister copper is fire refined in an anode furnace, cast into ‘anodes’ and sent to an electrolytic refinery for further impurity elimination.

Process Description Smelting Home

The products of the smelting ISASMELT™ process are tapped from the bottom of the furnace through a water-cooled taphole. Tapping of the furnace is by semi-automated machinery. The furnace can be tapped intermittently or continuously. The products flow into a settling furnace, where the matte or metal separates from the slag.
