How Gold Is Extracted By Cyanidation Process Refresh Science

Jun 17, 2020 The chemical that is used in the separation of gold from a rock is mercury. After the rock containing gold has been crushed to powder form, mercury is added to get the gold from the powder. Gold is dissolved in mercury to form an amalgam, just like the other minerals. In addition to that, using the cyanide solvent, gold is dissolved from its ore.

Extraction Of Gold Using Cyanide

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

This process does not result in gold that is 100 pure, but it does eliminate the bulk of the impurities.

Extracting Gold Howstuffworks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
