The principle of tin smelting is the chemical reduction of tin oxide by heating with carbon to produce tin metal and carbon dioxide gas. In practice, the furnace feed contains the tin oxide concentrate, carbon in the form of anthracite coal or coke, and limestone to act as a flux and a slag-producing agent. In a typical reverberatory process ...

Electrolysis. Electroplating. Electrolysis refers to the breaking apart of a molecule by the means of the electrochemical reaction. Electroplating refers to the passage of current through the solution with metal such that it gets deposited on one of the electrodes. Electrolysis is good for carrying out the non-spontaneous chemical reactions.

Apr 23 2014. Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. In the electro-refining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode. Both the cathode and anode are dipped in an electrolytic cell ...
