Active carbons for selective flotation of primary gold

The results of a study on the flotation of gold-copper-porphyry ore are presented. The quality of the obtained concentrates is confirmed by the efficiency of using activated carbon to reduce the excess of reagents accumulating in the collective concentrates. Detailed studies of concentrates of copper selection using scanning electron microscopy revealed the presence of carbon in their composition.

Effect Of Ore Pulp On The Adsorption Rate Of Gold

The effect of the presence of ore pulp on the adsorption rate of gold on activated carbon has been studied. A substantial reduction in the rate occurs when the pulp is present. The reduction in rate appears to be caused by two effects: permanent carbon pore blocking by ore particles and temporary shielding of the carbon particle surface, slowing gold access to the carbon due to the physical

Leaching and recovery of gold from ore in cyanide

2020-11-1  When activated carbon was added to filtered PLS, it took only 4 h to recover all gold from the solution. Similar level (i.e. 95%) of gold uptake from solution onto the activated carbon was observed with carbon-in-leach approach; however, the holistic recovery of gold in presence of activated carbon was ca. 13% lower than carbon-in-PLS.
