Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.
This is the same process for both copper and molybdenum porphyries. The smelter is basically a large furnace which melts the concentrate and drives off the sulfide to leave molten copper metal this is still contains impurities and it needs to be refined further to make it a salable product.
The Process. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage).
Flash smelting is a closed process and, consequently, offgas emissions can be efficiently controlled. Flash converting had its first appliion in the expansion and modernization of Kennecott''s copper smelter near Salt Lake City, Utah, which was implemented during 199295.
