How to Melt Gold Out of Rocks Sciencing

Mar 13, 2018You can't actually melt gold from rocks; if you hold a rock over a flame hot enough to melt gold and expect the gold to dribble out, you're going to be disappointed. The process of extracting gold from ore is a multistep one, and historically it has involved the use of some dangerous chemicals, including cyanide and mercury.

Heap Leaching Mining Fundamentals

Heap leaching is an industrial mining process of separating precious metals, copper and other minerals from ores. It involves a series of chemical processes through which the mineral ores are piled in the form of a heap and a leach solution is spread over the ore surface to leach metal from the heap.
