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 ...

A "refractory" gold ore is an ore that has ultra-fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. A refractory ore generally contains sulphide minerals, organic carbon, or both, generally leading to a …

If gold is found in the 200-300 or <325 mesh fractions, it is likely gold-bearing sulfides or free milling gold <~400 mesh. This gold is not practical to recover via gravity …
