bearing ores antimony

Techniques for the processing of antimony-bearing ores encompass a wide range of techniques from traditional hand sorting, which is dependent on plentiful and cheap labour, to technologically advanced, capital-intensive mineral processing. The main antimony products in international trade are stibnite and subordinate stibnite-berthierite …

Hydrometallurgical methods can be used to treat gold, arsenic, antimony, tin, and mercury contained in minerals, concentrates, and ores, as well as in complex compounds bearing any number of metals. Tetrahedrite leaching can be divided into two important dissolution mechanisms: alkaline and acid leaching [32,33].

Written documents must speak of antimony-bearing ores (e.g., stibnite) rather than metallic antimony. Thus, while referring to textual records in the following paragraphs, this distinction should be noticed. Antimony was not among the goods imported from Aššur, though it was traded by Assyrians in Anatolia [62: p.85].

The main methods used for the hydrometallurgical selection of gold and antimony are based on alkaline sulfide leaching. Alkaline sulfide leaching can also be used to extract chemically active antimony minerals from gold-bearing ores and concentrates before their cyanation.

Orogenic antimony-gold deposits contribute significantly to the global antimony resource base. China's orogenic antimony-gold deposits are primarily in southern Tibet. Investigations indicate that antimony combines and migrates with sulfur hydroxides in ore-forming fluids. Previous research on fluid inclusions in orogenic …

The largest Russian antimony ore deposits are reviewed analytically. The present-day physicochemical methods (nuclear quadrupole resonance, X-ray electron spectroscopy, multinuclear (13C, 15N, 31P) NMR) are used to develop innovative technologies. The innovative process for treatment of Au-Sbores of the Sarylakhsky and …

ASL technology was successful in the selective removal of mercury, antimony and arsenic from the Eskay Creek whole ores and concentrates. This provide a clean copper smelter feed.

Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb2S3), the antimony (Sb) forms stable ...

Antimony leaching from tetrahedrite-bearing ores was typically carried out by using Na 2 S-NaOH solutions. In the current paper, the detail mechanism of antimony leaching from tetrahedrite-rich concentrate via K 2 S and BaS lixiviants was investigated for the first time. Sample was characterized in terms of chemical, mineralogical, and …

Depending on the concentrations of gold and antimony, different categories of Au-Sb-containing sulfide ores can be distinguished: (1) ores in which gold is the main valuable component and antimony is a harmful impurity, (2) gold-bearing ores in which the amount of antimony is considerable and for which it is economically viable to recover ...

Approximately 36% of antimony was bioextracted by fungus from antimony bearing ferric oxyhydroxide after 14-day cultivation when the 8.9 mg·L −1 antimony concentration was used for pre-adsorption. However, no statistically significant change of antimony content in ferric oxyhydroxides was observed after cultivation when initial 48 …

The processing of persistent gold-bearing ores includes collective flotation of the sulfide minerals in the ore, bacterial oxidation of the concentrates, and cyanation of the cakes obtained by leaching. ...
