How Is Gold Mined in Australia Sciencing

The material can be pulverized and then exposed to lime, cyanide and other chemicals for purification. It can also be processed using a technique called flotation, in which gold ore powder is separated from other minerals by being placed in a liquid. The materials separate from one another since some sink and others will float in the liquid.
