Mineral processing WikipediaExtraction of gold using cyanide nzqagovtnz

Dewatering is an important process in mineral processing The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density This is done for a number of reasons specifically to enable ore handling and concentrates to be transported easily allow further processing to occur and to dispose of the gangue The water extracted from the ore by dewatering is This process of dissolving the gold using cyanide is known as leaching Sometimes some other precious metals can also be leached along wit h the gold for example silver This process of leaching is done in leaching tanks or by heap leaching where sodium cyanide is dripped onto a heap of gold ore and left to percolate its way through the heap of gold ore The dissolved gold in the form of
