Processing of Gold Bearing Antimony Ore: Mineral

2018-6-9  The gold was almost selectively and fully dissolved in the leaching solution when an oxidizing ammoniacal pressure leaching was carried out. The antimony, on

Processing of gold-antimony concentrates

The common global practice of processing antimony sulphide concentrates (20–30% Sb) is based on alkaline sulphide leaching followed by precipitation of metallic antimony by electrowinning. However, application of this technique to process sulphide concentrates that, apart from antimony, also contain gold, can be difficult as, together with antimony, up to 10–15% of gold can leach to the solution.

Antimony & Gold Tri Star

Refractory gold is in the ground gold ore trapped in sulphide lattice structures that conventional processes are unable to unlock. The clean roasting antimony technology developed by Tri-Star sold to joint venture company, Strategic & Precious Metals Processing LLC in 2015 has opened the treatment again of these world gold resources, estimated to be 30% to 50% of remaining gold in the ground.

2020-9-1  Fig. 1 shows the typical diagram of gold–antimony flotation process. Rougher flotation is the first step of flotation after the gold–antimony ore is ground, mixed with water and classified. Rougher flotation products include the rougher froth and the pulp, and the froth is located above the pulp in the rougher flotation cell.

Refractory Gold Ore Treatment Methods

2016-7-14  An 80 per cent gold recovery was made by the method of treatment described. It is generally known that antimony can be readily volatilized, and by roasting stibnite (Sb2S2) in an oxidizing atmosphere, antimony oxide can be driven off and condensed. At the same time, anyone who has had experience with such roasting knows that it is a delicate process.

Optimization of Alkaline Sulfide Leaching of Gold

This article covers a hydrometallurgical method for processing of a gold-antimony flotation concentrate in alkaline sulfide solutions. Thermodynamic analysis of the reaction stibnite with sulfide sodium and sodium hydroxide was performed. The chemical and phase compositions of the investigated material, mainly represented by compounds of antimony,

Processing of Gold Bearing Antimony Ore: Mineral

2018-6-9  A wet chemical process was developed for the separation of gold from gold-bearing antimony sulphide ores. The ore sample was taken from the mine Urquidi from Oruro in Bolivia. It contained roughly 33% Sb in the form of antimonite. 24% Si in the form of quartz, small quantities of Pb, Fe, Cu, and Ni as well as 63 g/t gold, 60% of it as visible gold.
