The gold-silver ore is fed into a ball mill with water and steel balls, reducing the size of the material, creating a slurry mixture. The solids in the mixture are roughly the same consistency as fine beach sand; the particle size required for the gold extraction process. Next, the slurry is thickened to remove a majority of the water.
