Processing technologies for gold-telluride ores

2016-9-12 · The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].

Everything about Gold Processing, Smelting, Refining ...

2020-12-4 · Gold Smelting. The smelting process is about extracting the precious metal from its ore. The process yields about 90% of pure gold. However, this percentage of gold is not acceptable in the industry, as it comes with other minerals, such as copper, silver, iron, or aluminum. Smelting comes as the most crucial step of the entire gold mining.
