26/03/2009· It can be extracted a few different ways. One way would be to heat the silver ore in the presence of a carbon compound like coal or coke. The carbon steals the sulfur off of the silver sulfide ore to reduce it to silver metal plus carbon disulfide. This is a redox (oxydationreduction reaction) Ag2S + C = Ag + CS2. Another way would be to dissolve the powdered ore/rock mixture in hot ...
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. Chat With Sales. Extractive metallurgy Wikipedia.
