Actually, there are many non-cyanide gold recovery chemicals such as amino acids, hydroxynitrile and other substances can also be used as non-cyanide gold recovery chemicals for gold extraction. As people attach more and more importance to ecological protection, the use of non-cyanide gold recovery chemicals will be more and more extensive.
The extraction process, known as urban mining, involves several steps. First, the electronic components are sorted and dismantled. Then, through a combination of mechanical and chemical processes, the gold is separated from other materials.

This causes gold to collect on the negative terminals. Smelting, which results in nearly pure gold, 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, the gold separates from the metal used to make the terminals. Workers ...
