What is the role of silica in the extraction of copper from copperpyrite ore? Share with your friends. Share 6. During the roasting of pyrite ore, a mixture of FeO and Cu 2 O is obtained. The role of silica in the metallurgy of copper is to remove the iron oxide obtained during the process of roasting. ...
The roasted ore is mixed with coke and silica (sand) SiO 2 and is introduced in to a blast furnace with 1200oC. The hot air is blasted and FeO is converted in to ferrous silicate (FeSiO 3). FeO + SiO 2 FeSiO 3 Cu 2 O + FeS Cu 2 S + FeO FeSiO 3 (slag) floats over the molten matte of copper. A matte of 60%Cu containing has been produced ...

Jan 09, 2017· Limestone is used in iron extraction to remove impurities from the iron and becomes molten slag. The calcium carbonate (CaO3) in limestone catabolically reacts, forming calcium oxide(CaO) and carbon dioxide(CO2). CaO is highly reactive when subjec...
Avoiding the pollution problems in the extraction of iron from the ore. Not having to find space to dump the unwanted iron if it wasn''t recycled. (Offsetting these to a minor extent) Energy and pollution costs in collecting and transporting the recycled iron to the steel works.
Alumina Extraction Problem. In the standard Bayer Process for refining bauxite to produce alumina, the dissolution of the alumina in the ore to form sodium aluminate is accomplished in autoclaves under high pressures varying from 70 to 200 pounds per square inch.
Magnesium: extraction; Brife introduction; Magnesium is found in solution in seawater (about kg m3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (). Both of the two types of resources can be used as raw materials to manufacture magnesium metal.
The method used to extract metals depends on the reactivity of the metal. Metals are used for a variety of purposes. An alloy is a mixture of a metal and another element.
Concentration of the copper(II) sulfate solution by solvent extraction. The very dilute solution is brought into contact with a relatively small amount of an organic solvent containing something which will bind with copper(II) ions so that they are removed from the dilute solution. The solvent must not mix with the water.
