Gold Recovery And How To Choose The Right Process ...

In many cases, portions of sulfide-associated gold can be considered free-milling and can be recovered using the gravity recovery process described above. For the portion of sulfide-associated gold that is not free-milling, different tactics are needed to extract the gold. Typically, this type of gold is recovered with froth flotation.

Recovery of gold from sulfide refractory gold ore ...

2021-4-1  Sulfide gold ores account for a large proportion of refractory gold ores, therefore, it is very meaningful to recover gold from sulfide gold ores (Ubaldini and Vegliò, 2000, Saba, 2011, Hammerschmidt, 2016). Moreover, the major gold leaching process for extracting gold from ores and concentrates is still cyanide leaching.

Processing technologies for gold-telluride ores

2016-9-12  Ellis provided a very detailed plant cyanide leaching process for gold telluride minerals. About 23% of the gold in a KCGM concentrate was gold tellurides, mainly calaver-ite (AuTe2) with small amounts of petzite (Ag3AuTe2). Ellis introduced an extra oxidative step using hy-pochlorite leaching immediately after leaching with 0.1wt% NaCN at a pH value of 9.2 for 24 h. Lime was used to adjust pH, and the leaching conditions were changed to a lower cyanide concentration. According to the report, several re-peated oxidation steps were needed for particle sizes larger than 10 µm. Pleysier et al. also examined the leaching process of gold telluride ores from a KCGM flotation con-centrate sample. The leaching
