When crushing bentonite, the output can be increased by 30-40%. And more energy saving in the crushing process. The particle size of bentonite fragments can be changed by adjusting the wedge or gasket adjustment device between the two rollers. Ftmmachinery roll crusher for sale: $3,500/ Set (the lowest price) Bentonite drying process

Step 5: Refining and Smelting. The eluate solution is pumped through electro-winning reactors where gold is plated onto cathode steel mesh or wool. (Electrowinning is a process of recovering metals from a solution by passing a current through it). The plated gold is then washed off and dried in cylinders called calciners, inside heated furnaces.
