Precious metal refining equipment for extracting gold and silver from electronic waste

Chemical refining in e-waste mainly refers to the treatment of toxic substances and pollutants in it to ensure that the treated materials will not cause pollution to the environment. Specifically, the steps of chemical refining of e-waste can be divided into the following aspects.

Acid washing: The separation of valuable metals in e-waste can be done by acid washing. The metal part of the e-waste is put into the acidic solution, and the corrosiveness of the acidic solution is used to separate the metal from other impurities.

Dissolution: Dissolution can be used to treat some toxic substances and pollutants that are difficult to recover. Put the toxic substances and pollutants in electronic waste into chemical solvents and use the principle of chemical reactions to separate them out. Commonly used chemical solvents include nitric acid, hydrofluoric acid, sulfuric acid, hydrochloric acid, etc.

Filtration: In the process of chemical treatment, it is usually necessary to filter the solution after the reaction. The purpose of filtration is to remove impurities and solid particles from the solution to obtain a pure solution.
