The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound. Electrolysis Electrolysis is the most powerful extraction method. But it takes a lot of electricity and that makes it expensive. Hence, electrolysis is only used for the most reactive metals.

Electrolysis of copper. In this process, the positive electrode (the anode) is made of the impure copper which is to be purified. ... The metals copper, silver gold and platinum are less reactive than hydrogen and they do not replace hydrogen from water or acid. ... The extraction is done by electrolysis.

Apr 24, 2017· At this point, treated high grade ore is leached with cyanide and gold is collected onto activated carbon with the cyanide solution being recycled. The goldcarbon mixture is put in a vessel where the gold is removed chemically. The carbon is then recycled. The gold is then extracted from the solution by electrolysis or chemical substitution.

I n examining the electrolytic extraction of aluminium from bauxite and alumina, we must first briefly explain the element called aluminium and the minerals and ores that contain this very important metallic element. Aluminum is the third most plentiful element in the earth's crust, being found abundantly as trioxosilicates(IV) in rocks and clays. . The main source of aluminum is the mineral ...

Electrolysis is widely used for Electroplating. Implementation of Electrolysis: In medieval times, aluminium was almost as precious as silver. Its extraction was not known and pure aluminium was extremely hard to come by. The application of electrolysis turned aluminium from a precious metal to one of the most largely used metals by humans.

This attractive method of separating gold from silver has made some headway, and will in many cases replace other methods of parting. The electrolyte used is a solution of silver nitrate, or it may be started with dilute nitric acid. The cathode consisting of thin silver plate and the anode of the silvergold alloy usually in plates about 3/8 inch in thickness.
