Extraction Of Gold From A Lowgrade Double Refractory Gold

The treatment process of a low-grade refractory gold ore containing sulfide minerals and carbonaceous matters was studied in this work. The gold extraction of this ore by all-sliming cyanidation was only 11.75. Hence, a pretreatment was necessary. In this paper, a flotation-preoxidation-cyanide leaching process was developed.

Recovering Gold through the Froth Flotation Process

Recovering Gold Through The Froth Flotation Process

Feb 06, 2018 Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
