Smelting - Wikipedia Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores including silver iron copper and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behind.
Scrap - Wikipedia It is cheaper to recycle steel than to mine iron ore and manipulate it through the production process to form new steel. Steel does not lose any of its inherent physical properties during the recycling process and has drastically reduced energy and material requirements compared with refinement from iron ore.Processing& 0183;& 32;
Dealing with Environmental Pollution in the Iron and Steel Steel plants with electric arc furnace release dust containing heavy metals and some organic compounds. Steel industry is also a source of carbon dioxide CO2 emissions which is generated during iron and steel making operations either as a result of the reaction of carbon coke with iron oxide in the blast furnace or from a power plant producing electricity used in the production of steel.
Heap leaching - Wikipedia This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores as high as 1000 kg of acid per tonne of oreProcess& 0183;& 32;
