Five Common Gold Separation Methods You Have to

This method is called adding Hg in the ball mill that is to say while grinding the minerals, the Hg will be added to extract the gold. Another method is adding the Hg outside the ball mill to extract the gold. The Hg spreads in the gold particles to form the solid solution finally. When heating the solid mercury, the sponge gold will be got. 03

The Campbell mill treats both free milling and refractory gold ore at a rate of 1,850 t/d. Run-of-mine ore is crushed in three stages to 19 mm and then enters a two-stage rod and ball mill circuit. The slurry is pumped to a bank of eight cyclones, the overflow going to the flotation circuit and the underflow going to the ball mill.
