Dec 05, 2019· The safest way toextract goldfrom rocks at home is to crush the rocks. However, you might use mercury toextractthegoldif you’re able to obtain some, though this is dangerous. While both mercury and cyanide can be used toextract goldfrom rock, it's hazardous to both your health and the environment to use them.
Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
Apr 24, 2017·Goldis an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this.

Nov 28, 2016· Scientists capture minute particles of gold during the burning process. To secure the precious metal, smoke generated during combustion passes through a 100-fold purifying filter. The contaminants are washed out with water and the gold is captured by the filter. For every ton of coal burned, one-half gram of gold can be recovered.
This causesgoldto collect on the negative terminals. Smelting, which results in nearly puregold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, thegoldseparates from the metal used to make the terminals. Workers ...
