Physical processing methods are widely applied in mineral separation. In the case of gold ores, physical separation can be employed to produce concentrates, and in the case of free-milling ores or to produce gold intermediate-enriched mineral products, by rejecting gangue material, which facilitates more effective hydrometallurgy.
However, these oxidized PGM ores are currently not mined or treated due to insufficient recoveries using established metallurgical techniques. The complex mineralogy and polymodal distribution of PGM in the oxidized ores pose a number of challenges to the metallurgist from a mineral liberation and extraction perspective.
Primary auriferous ores in terms of their mineral composition and textural and structural characteristics belong to the category of refractory mineral raw materials [1, 2].The extraction of gold from these ores is of particular importance for all gold-mining and processing countries in the world [], since the reserves of placer gold are depleted, …
Chemical beneficiation is a method that uses chemical reactions to dissolve gold from raw ore, and then recovers gold through precipitation, extraction and other methods.
The aim of this paper is to present a systematic review of the mineral processing of gold ores, with special focus on alternative leaching reagents to cyanide that can facilitate more sustainable extraction.
