The specific process is as follows: the products after grinding enter the jig for a re-election. The overflow part goes into the pump box for storage. The underflow part is pumped into the shaker by the slurry pump for secondary and tertiary reselection. Gold particle products can be obtained after reselection.

Outotec BIOX® Process. The Outotec BIOX process was developed for the pre-treatment of refractory ores and concentrates ahead of conventional cyanide leach for gold recovery. The gold in these ores is encapsulated in sulphide minerals such as pyrite, arsenopyrite, and pyrrhotite, thus preventing the gold from being leached by cyanide.

Most methods of water-based gold extraction are dependent on gold's lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
