Suphidic Gold Ore Pretreatment

01-03-2013· In this paper, the selective and bulk flotation methods are considered as primary sulphidic refractory gold ore pre-treating options. The results show that it is impractical to remove arsenic (As) and antimony (Sb) from downstream processes by using selective flotation.

Refractory gold ores with low grades, fine dissemination, and high impurity content have become the main ore source of gold in China, limiting the ease of gold ore processing.

01-03-2013· Abstract. In sulphidic refractory gold ores, fine gold particles may be highly disseminated and locked up in sulphide minerals such as pyrite and arsenopyrite. Hence, pre-treating processes are necessary to extract gold for further processing methods like cyanidation. In this paper, the selective and bulk flotation methods are considered as,

01-04-2021· Typically, gold is encapsulated or finely disseminated in refractory gold ores and the direct cyanidation is not effective for gold extraction from these ores, even after the ore is ground to exceeding small particles (Nazari, 2017, Corrans and Angove, 1991).Especially for sulfide refractory gold ores, in order to recover gold, many oxidation pretreatment

Gold ores are considered refractory if gold extractions from a conventional cyanidation process are less than 80% even after fine grinding. 1) Arsenic-bearing refractory gold ore has stones extremely difficult to deal with. In the stones, gold is locked up in arsenic mineral matrix as the form of microscopic or submicroscopic lattice.
