In this paper, the selective and bulk flotation methods are considered as primary sulphidic refractory gold ore pre treating options. The results show that it is impractical to remove arsenic (As) and antimony (Sb) from downstream processes by using selective flotation.
CARBON ADSORPTION RECOVERY. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution. The CIL process is frequently used when native carbon is present in the gold ore. This native carbon will adsorb the leached gold and prevent
More sophisticated gold ore beneficiation technologies were developed in the 20th century and accounted for the surface properties of finely dispersed gold. Today, flotation, which relies on the attachment of particles to suspended bubbles, plays an important role in modern gold ore beneficiation.

GOLD RECOVERY BY FLOTATION. A test on a sample, crushed to pass a screen of 120 holes per linear inch, containing $37 gold and 4.8% copper, gave a recovery by flotation alone of 90% of the gold and 98.5% of the copper, but left $8 gold in the tailing. The concentrate carried 44% insoluble matter, which could be reduced by re treatment.
