Extracting a metal from its ore - chymist

2006-6-27  Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis. Metals with low chemical activity, such a gold and silver are normally found in their pure ...
