Virtually all the molten copper produced by smelting/converting is subsequently electrorefined. It must, therefore, be suitable for casting into thin, strong, smooth anodes for interleaving with ...
Fire-refined copper can be cast into either anodes, which are used during electrolysis, or billets. The anodes are submerged in a sulfuric acid solution containing copper sulfate. As copper is dissolved from the anodes, it deposits on the cathode. Then the cathode copper, which is as much as 99.99 percent pure, is extracted and recast.
Outotec Flash Smelting and Kennecott- Outotec Flash Converting for copper Outotec Flash Smelting combined with Kennecott- Outotec Flash Converting is an integrated solution for high-capacity smelters. Matte from the flash smelting furnace is granulated and fed to a flash converting furnace in the same fashion as concentrate.
The pyrometallurgical copper production route typically involves a three-step process from feed to anode: (s)melting, converting and fire refining.1 Two types of furnace are in use in the refining section: the rotary furnace type dominates in primary copper production, while secondary smelters tend to use hearth refining furnaces because they are more suitable …
reducing the furnace atmosphere, cuprous oxide (CuO) is converted to copper. Fire-refined copper can be cast into either anodes, which are used during electrolysis, or billets. The anodes are submerged in a sulfuric acid solution containing copper sulfate. As copper is dissolved from the anodes, it deposits on the cathode.
This oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining. At this point, the copper is cast into anodes, the shape and weight of which are dictated by the particular electrolytic refinery. Leaching

For copper metallurgy, bottom bowing furnace can treat copper oxide, copper sulfide ore, copper/nickel concentrates, copper scrap, brass and electronic waste material. The bottom blowing furnace has the advantages of less energy consumption, high utilization rate of oxygen and producing less off-gas amount with high SO 2 concentration.
The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining. The anode plates are approximately 1m x 1m x 0.05m in size, and weigh 380 kg per plate.
The conversion of liquid matte in a rotating converter is a batch operation, but newer continuous processes utilize stationary furnaces similar to those used in smelting. Continuous systems have the advantage of reducing the gaseous and particulate emissions normally produced during conversion. The final step consists of fire refining the blister copper to reduce the sulfur and …
Copper Anodes: In copper processing, a copper anode is an intermediate product from the smelting furnaces which is used as a copper source from which to make copper cathodes during electrolysis. In electrolysis, it is the positive terminal. Oxidation occurs at the anode. The anode is replaced when it's been eroded too far and risk falling apart.
99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into "anodes", and sent to an electrolytic refinery for further impurity elimination. Roasting is performed in copper smelters prior to charging reverberatory furnaces. In roasting, charge material of copper concentrate mixed with a siliceous flux ...
Characteristics. 1. Feed material copper grade as low as 10% and moisture up to 8% can be directly smelt; 2. Up-to-date forged copper jacket guarantees high safety for furnace operation and long campaign life; 3. Continuous smelting and converting/reduction process, high automated operation, stable SO 2 content (12-18%) in off-gas in favor of ...
The latest innovation with the ISASMELT™ technology is continuous copper converting. The ISACONVERT™ process offers an alternative to batch copper converting operations, such as Peirce-Smith (P-S) converting. It is an attractive option due to its flexibility to treat solid feed and efficiently capture SO2 and reduce in-plant fugitive emissions.
The blast furnace and converter may be omitted from the process if average copper content of the scrap being used is greater than about 90 percent. The process used by 1 U. S. facility involves the use of a patented top-blown rotary converter in lieu of the blast, converting, and reverberatory furnaces and the electrolytic refining process
