Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations were …

We focus on the leaching of a number of potentially toxic elements (PTEs) from residues from the processing of antimony ore. The PTE content of ore processing waste and solutions generated by leaching experiments were determined for a suite of PTEs associated with the ore mineralization. These were Sb, As, Hg, Pb, Cd and Zn.

Based on these findings, a cleaner production process was proposed to selectively remove antimony in the form of sodium pyroantimonate from refractory gold ore. In this work, the complete process is presented in detail so as to provide guidance for the extraction of antimony from antimonial refractory gold ores.

Antimony Beneficiation process. 1. Hand Selected. Antimony ore is often produced as coarse monomer crystals or massive aggregate crystals. Due to the large differences in color, luster, and shape between antimony …

The Reefton sulfide concentrate was transported 700 km to the Macraes orogenic gold mine (active from 1990) for processing through a pressure oxidation autoclave at 225 °C. The Macraes ore has low Sb contents, so the temporary introduction of a Sb-rich component produced a short-term Sb signal in the autoclave system and …

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 …

Up to now, studies on pollution form antimony ore extraction and processing are mainly focused on Sb in waste water, waste gas and waste solid residues from antimony beneficiation and metallurgy, the distribution and spatial characteristics of pollution, the factors affecting its migration and release, transformation of chemical forms and its ...

This mixture was then combined with the laterite ore to give between 25.1% and 25.5% of the total solids as concentrate in each test to provide the necessary acid for leaching of both the concentrate and laterite ore. ...

The powdery crude antimony trioxide is reduced by a carbonaceous reductant in a reverberatory furnace at 1,000–1,200 °C to produce crude antimony. Crude antimony can be produced by the precipitation smelting process. The typical pyrometallurgical antimony production process using sulfide ore is shown in Fig. 1.

The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony.
