The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you're able to obtain some, though this is dangerous. While both mercury and cyanide can be used to extract gold from rock, it's hazardous to both your health and the environment to use them.

Mercury processing - Extraction, Refining, Recovery: The pyrometallurgical extraction of mercury from its ore is essentially a distillation process. When heat is applied to the sulfide ore in the presence of air, oxygen combines with the sulfur to form sulfur dioxide, and the metal is liberated at a temperature above its boiling point. The gases are then passed …

1. Introduction. Currently, cyanide is the predominant lixiviant used to extract gold due to its strong complexation with gold and the technical simplicity of the leaching process (Avraamides, 1982, Habashi, 1987, Marsden and House, 2006).However, the use of cyanide can bring challenges in terms of environmental, health and safety aspects …

Dredging was a large-scale means of extracting gold from extensive river-flat deposits. Dredges were like huge floating factories; operating in a pond, they excavated the gravels in front of them with large buckets, processed the gravels on-board, and dumped the treated material behind. By far the most successful employment of pump sluicing and ...

To extract, a sand breaker or an artificial dam is created to keep the water back. Then the river bed or sea is dug mechanically or manually, removing ores that are sent to the refinery for extraction. So diamond mining is a job that requires the removal of hills to surmount any chances of success. The procedure uses huge extraction machines ...
