Tailings Storage Facilities
Many gold operations process ore that contains sulfide minerals, which have the potential to oxidize over time and generate acid. This process can, in turn, lead to the concentration and mobilization of heavy metals, which may be present in very low concentrations in the tailings, leading to contamination of the local groundwater.

Beneficiation of Gold and Silver Ores | SpringerLink
Flotation of ore at a top-size of 3 mm, followed by gravity concentration of the flotation tailings, has been applied previously in South Africa to treat Witwatersrand gold ores resulting in the production of a 40% mass pull at an overall gold recovery of 98% (Lloyd, 1979). Coarse particle flotation of particle ranging from 3 to 5 mm is common ...

Alternative Lixiviants to Cyanide for Leaching Gold Ores
Chlorine, bromine, and iodine are well-known lixiviants for leaching gold, as reviewed by Tran et al. (2001). Chlorination was applied extensively in the late 19th century before the introduction of the cyanidation process. Bromine/bromide for leaching gold from ores was reported as early as 1846.
