Figure 23.3.1 23.3. 1: A Blast Furnace for Converting Iron Oxides to Iron Metal. (a) The furnace is charged with alternating layers of iron ore (largely Fe2O3) and a mixture of coke (C) and limestone (CaCO3). Blasting hot air into the mixture from the bottom causes it to ignite, producing CO and raising the temperature of the lower part of the ...

The next step in the extraction of zinc is called roasting. The concentrated ore is finely ground into small pieces and then suspended in a rising stream of air. The sulphur content can be reduced hugely with this process. This also converts the zinc blende to ZnO which is way more reactive. The reaction occurring here is.

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
