All ores are calcined in a rotary calciner. The calcined ore is transported into the percolation tank with a mining cart. Lime is directly added to the ore, and the first cyanidation time is 12 hours.
A mercurygold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold that is 100% pure, but it does eliminate the bulk of the impurities.Mining Explained: A Detailed Guide on How ,Most people think of crypto mining simply as a way of creating new coins.
