Gold Mining Extraction and Purifiion# Because of gold's inertness some 80% of gold within ore is in its elemental state. There are several processes used in gold mining for extracting, and then purifying it. Amalgamation is a mercury based process which works because of gold's willingness to be dissolved by mercury.
· Traditional extraction costs 1,520 for one kilogram of gold. The experimental method costs 66 for one kilogram and leaves behind reusable waste. Besides the monetary value, the technology weighs in by solving one big problem posed to ecyclers and other scrap metal recyclers: the fact that gold is traditionally hard to dissolve without rendering other metals unusable.
