The Common Gold Mining Process – Gravity Separation
2019-12-4 · Chute for gold mining is an ancient and still used gravity separation method. And the chute is the main equipment used in the gold mining, which is a narrow wooden (or steel) chute with a dip angle of 3°-4° (maximum of 14°-16°). The working principle of chute: After the slurry is fed into the chute from the head of the trough, the ore ...
