Antimony in the environment comes from natural processes (ore weathering, volcanic activity) and human activities (mining and smelting, use of antimony containing products, fossil fuel combustion, etc.). Similar to many elements, the toxicity of antimony is closely related to its chemical form, and the toxicity of Sb(III) is much higher than Sb(V).

SEM analysis was carried out to complete the study of the phase change of compounds in the oxidation of mineral sulfides. Roasting of refractory gold ore with a composition of 180 kg NaClO 3 and 180 kg water/ton ore reached a temperature of 470 °C at a microwave power of 400 watts for 30 minutes. Total oxidized sulfur reached 90.6%, …

The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 metric tons per year.

Antimony has been known and used since ancient times, but its applications have increased significantly during the last two centuries. Aside from its few medical applications, it also has industrial applications, acting as a flame retardant and a catalyst. Geologically, native antimony is rare, and it is mostly found in sulfide ores. The main ore …

Another benefit of having a refractory-ore processing plant is the transfer of know-how and experience between different operations. Miners can tap into the opportunity for lower costs per ounce offered by higher-grade refractory gold reserves. However, when considering this potential, they need to factor in higher capital and operational costs.

The plant extracted antimony from stibnite ore, which was transported to the site from a mine at Dorrigo. Antimony was extracted from the ore by crushing and processing with numerous chemicals. Antimony was historically used in flame retardants for textiles, plastics, rubber and building materials. The metal was also used in alloys and batteries.
