Flotation is the most important extraction method for antimony deposits. Antimony sulfide deposits are easy-to-float deposits, and flotation methods are mostly used to improve the crystal position of the ore.
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 low (<100 mg/kg) …

Stibnite, the antimony sulphide mineral, responds much better to flotation after being activated with lead nitrate. The theory generally accepted on activation is that the activating substance, generally a metallic salt, reacts with the mineral surface to form on it a new surface more favorable to the action of a promoter.
antimony content starting from 1.5 to 8 g / t for gold and from 0.6 to 10% for antimony, but on the other side, it is difficult to cyanide. Antimony m inerals are leached in alkaline cyanide ...
The flotation concentrate is dewatered through thickeners and with filtration to produce a final antimony-gold concentrate product, which is bagged, packed into shipping containers and shipped to customers overseas. The feed to the plant during 2020 and 2021 was between 11.0 and 12.1g/t Au and 3.5 to 4.5% Sb.

Typical antimony content in the feed to flotation varies widely among stibnite froth flotation testwork carried out in the reviewed studies, which covers industrial operations as well as bench-scale studies on ore samples from stibnite-bearing deposits worldwide.
Most Chinese mineral processing plants use antimony arsenic gold and sulfur mixed flotation process program, and the mixed concentrate is directly produced as gold concentrate. However, the antimony content in the gold concentrate is …
The antimony ore beneficiation methods mainly include manual separation, gravity separation, flotation, and other methods. Select the beneficiation process of a specific ore based on the physical and chemical properties of the ore type (natural type and industrial type), mineral composition, structural structure, and process particle size of useful minerals.
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.

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings …
