Extract gold from the particles by some gold beneficiation methods. Ⅰ. Crushing and screening stage. The crushing and screening stage in the industry is mainly composed of three-stage and a closed-circuit process. Gold ores need to go through coarse, medium, and fine crushing processes to be reduced into smaller pieces.

Though found in only very small quantities, the concentration of gold in electronic waste, such as computers and mobile phones, is 80 times higher than that found in natural gold ore. In fact, electronic waste is thought to contain as much as 7% of the world's gold, and up to 300 t of gold is used to produce new electronics every year.
