How to Melt Gold Out of Rocks | Sciencing

How to Melt Gold Out of Rocks | SciencingMar 13, 2018· You 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.

Gold Cyanidation Ground Truth Trekking

Gold Cyanidation Ground Truth TrekkingCyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock. This process usually takes place inside a mill or other mining facility.
