definition of electrolytic iron ore refining

definition of electrolytic iron ore refining

Apr 29, 2020 Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.

Electrolytic Refining

Electrolysis or electrolytic refining is a technique used for extraction as well as purifiion of metals obtained by any refining method. In the electro refining process, a block of impure metal is made the anode and a thin sheet of metal is made the hode.

Metal extraction

 · The metal ions in the ore compound are forced by electrical energy into accepting electrons and producing free metal atoms. o Another definition of reduction is electron gain. o during the electrolysis of molten aluminium oxide the following reaction happens. Al3+ (aq) + 3 e – ==> Al(s) Al3+ + 3e– ==> Al So, once again the metal ore compound is reduced to the metal.

The metallurgy of copper, bauxite and iron ore are founded on the same principle of progressive ore refining to obtain the metal. (Uranium technology, however, is very specific.) Both copper and bauxite metallurgy encompass two distinct phases: smelting the ore in order to obtain a product with very high metal content; and the electrolytic refining of this product to obtain pure metal.
