Characterization of Gold in Complex Historical Refractory Tailings for Enhanced Process Optimization

Mineral Processing and Extractive Metallurgy Review, 2023
Historical gold tailings show promise as a secondary resource amid declining primary deposits, yet conventional cyanidation falls short, resulting in recoveries below 90%. An essential pre-treatment process is crucial for optimal recovery, contingent on understanding the complex mineralogy of the tailings.

Flotation of mercury from the tailings of the Agh-Darreh gold processing plant, Iran [PDF]

Journal of the Southern African Institute of Mining and Metallurgy, 2017
The feed ore to Agh-Darreh gold processing plant (Takab City, Iran) contains 2 ppm Au, 7 ppm Ag, and 120 ppm Hg. After cyanide leaching of the feed at pH 10.4, 80% of the total mercury (in the form of cinnabar and metacinnabar) goes to the tailings dam. In this research, separation of mercury from the tailings by flotation was investigated. The effects
