11. Extracting Metals (V2.0) metals less reactive than carbon can be extracted from their ores by reduction using carbon, coke or charcoal. platinum, gold, silver and copper can occur native and do not need to be extracted. the reactivity of a metal determines how it is extracted. metals are often found combined with oxygen as oxides.

A method and apparatus for extraction of precious metals from their ores and the product thereof. Oxidized ore comprising a precious metal is exposed to a leaching solution (lixiviant) comprising a relatively high concentration (fugacity) of dissolved hydrogen sulfide gas, a relatively high concentration (activity) of bisulfide ions, and a relatively low concentration (fugacity) of dissolved ...

2006-6-27 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.

2016-4-11 Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes.. Bauxite is the general name given to the hydrated oxides of aluminum.
