Gold Extraction - an overview ScienceDirect Topics

The decrease in gold extraction only occurred on leaching the blend. After 12 months of laboratory investigation, three options were identified to solve the problem: leaching at pH value lower than 10, increasing the DO of the slurry, or using lead nitrate. The significant effect of pH on gold leaching pointed to stibnite as the origin of the problem.

Equilibrium and mechanism studies of gold(I)

2020-8-11  Although these extractants exhibit excellent extraction performance for gold(I) (extraction efficiency of E > 99%), fluorine-containing anions in the ionic liquid are exchanged into water because of anion exchange reactions, and highly toxic fluorine-containing ions in water cause serious environmental problems [23, 24]. Therefore, ILs that contain fluorine cannot be called truly green solvents.
