How Antimony is Processed by Flotation
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of …

Antimony Metallurgy
The powdery crude antimony xide 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.

Recovery of antimony from acidic and alkaline leaching
A process was developed to recover antimony from an Sb 2 O 3 ore source, using selective acidic or alkaline leaching followed by antimony electrowinning. Sb could be leached with an efficiency of 85 % using 5 M NaOH and 87 % using 5 M hydrochloric acid/5 M sulfuric acid as the digestion solution at 80 °C for 8 h.

Antimony Mobilization through Two Contrasting Gold Ore Processing
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 …
