3. Magnetic separation: After washing, the 02mm material flows into the drum magnetic separator to remove the magnetic ore, and then is stored in the slurry pool. 4. Gravity Separation: The 210mm material will flow to the gold sluice box, so the 210mm gold particles can be captured. And the +10mm material will be sent to the waste pile.

Step 5: Refining and Smelting. The eluate solution is pumped through electrowinning 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.
