Extracting a metal from its ore - chymist.com

Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction.

Extracting Metals by Electrolysis

extracting metals from their ores: reduction with carbon electrolysis (using electricity). The method of extraction which is most appropriate depends on the reactivity of the metal being extracted. Most metals are found combined with other elements, as compounds in ores. These metals must be extracted from their ores before they can be made useful.

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...

Extraction of Gold

The ore is reduced to a fine state of division and amalgamated simultaneously in a stamp-mill, the solid gold-amalgam separated from the liquid mercury by filtration through leather under pressure, and the mercury distilled. Complete extraction of the gold by amalgamation is impossible, a part remaining in the mud of the stamp- mills.
