Gold Ore Processing Decantation Tanks

The gold bearing liquid is then separated from the leached solids in thickener tanks or vacuum filters and the tailings are washed to remove gold and cyanide prior to disposal the separation and washing take place in a series of units by a process referred to as counter current decantation ccd gold is
