Test of Comprehensive Recovery of Cyanide Residue
Kuangchan zonghe liyong, 2023 This is an essay in the field of mineral processing engineering. Cyanide tailings of a gold mine contain gold 0.45 g/t, and the gold mainly exists in the form of vulcanized gold and is mainly distributed in coarse particles.

Gold Recovery from Cyanidation Tailings Using Flotation Process
Archives of Metallurgy and Materials, 2021 The gold recovery from cyanidation tailings was only 4.01% with the general flotation process, the surface analyses of flotation products were performed, and the results showed that the poor gold recovery with general flotation process was due to the passive films covering the surface of the gold bearing pyrite.

Identification of pollution sources in closed mining sites with an Impact on the quality of surface water in the Brad area [PDF]
MATEC Web of Conferences, 2021 Pollution caused by closed mining activities is particularly difficult to treat because it dates back a very long time. Water contamination results from large-scale disturbance of the land on which the underground exploitation of the useful mineral ...

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.
