The recovery of gold from leached calcine residues
Refractory pyrite telluride concentrates were examined and the mineralogical association of residual gold was investigated.
Possible ways to improve recovery, including fine milling, gravity concentration, magnetic separation, acid leaching and digestion, pressure leaching and retreating were examined.
Includes a Literature Review of the technology of extraction of gold from refractory ores.
