The early development of the reverberatory furnace for smelting copper ores was the work of the Welsh smelters, particularly those of Swansea. The first record of a reverberatory furnace is made by Jars, who states that copper-smelting was effected in reverberatory furnaces at Middleton-Tyas, in Yorkshire, England. The first patent, of any importance, for improvements in reverberatory furnaces ...

Although the unit cost of power is not available, the cost of electric smelting of copper concentrates and converting to blister is 800 Finnish marks, or about $17.50 per ton of copper. With regard to the price of power in large quantities, Edvard Svanoe, Oslo, Norway, stated in The Engineer ( London ) for dune 18, 1937, that electric power in ...
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. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised ...
A final heating in an anode furnace is used to burn off the remaining oxygen. An interesting aside is that for every ton of copper produced, 1.5 tons of slag and 2 tons of sulfur dioxide are also produced as waste products. The final step is the conversion of the impure copper to pure copper.

Equipment Used For Firing/Smelting Ore Furnace Or Oven For Firing/Smelting: It must heat to 1950 degrees F for gold and 2100 degrees F for silver. A muffle furnace is best. It fires to about 2300 degrees F and the ingredients can be easily added to the ore while firing. Crucible: Clay or graphite crucible to use in a muffle furnace.
Smelting furnaces produce liquid Cu–Fe–S matte (usually 60–70% Cu), which must have its sulfur and iron removed to make copper metal. This is most frequently done in submerged-tuyere Peirce–Smith (Fig. 4) and Hoboken converting furnaces using air (often slightly O 2-enriched) as the oxidant.The process is similar to submerged-tuyere smelting except that the feed is molten matte, not ...
