The sulfide ore beneficiation method mainly uses flotation or other combined process to extract valuable minerals from sulfide ore.
In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation …
Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from …
Mineral ore beneficiation and value addition has become a key factor for economic growth in Africa. Froth flotation process is used to concentrate relatively low grade ores.

Lead-zinc ore usually exists in the form of sulfide ores, such as sphalerite and galena. Flotation is the most commonly used method.. The lead-zinc ore processing solution is adjusted and used in combination according to ore characteristics, metal grade and other factors, such as gravity-flotation, magnetic-flotation, and gravity-magnetic-flotation, in …
Results obtained from studying the material and mineral compositions of the ore, the behavior of the minerals in the beneficiation process, and the electrochemical interactions that those minerals undergo were used to develop a technology for extracting antimony in sulfide flotation concentrate KSUF-4.
The flotation process is a material separation method with air bubbles as the medium, and is suitable for mineral processing plants of metallic minerals and non-metallic minerals.
From the mid 1950s the Sunshine mill produced these two concentrates from the flotation process; ... In ancient times, in extracting antimony from sulfide ore by the addition of iron, a starlike fern shaped crystalline pattern appeared during the course of solidification. This was dubbed the "Philosopher's Signet Star" in 1610 and until ...
Once mined, the ore is then concentrated using techniques like gravity separation or flotation to increase its antimony content. The concentrated ore is further processed through smelting, where it is heated in a furnace to separate antimony from other impurities, resulting in antimony metal or antimony oxide, depending on the …
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.
Antimony ore samples (mean assay 187 per cent antimony) from Endeavour Inlet, Marlborough Sounds New Zealand, were tested for upgrading by flotation to a saleable product (60 per cent antimony).The effects of activating agents, collectors, frothers, pH, conditioning time, and particle size on the recovery and grade of a stibnite flotation …

In our existing operations in Montana, we produce antimony oxide, sodium antimonate, antimony metal, and precious metals. Antimony oxide is a fine, white powder that is used primarily in conjunction with a halogen to form a synergistic flame retardant system for plastics, rubber, fiberglass, textile goods, paints, coatings and paper.
Flotation is often used to increase antimony recovery by selectively attaching air bubbles to mineral particles. Another innovative method is magnetic …
Introduction: The flotation machine is important for realizing the flotation process. It can process metal or non-metal minerals, such as copper, lead-zinc, lithium, antimony, fluorite, talc, etc. After the minerals undergo wet grinding, the minerals dissociated into monomers are adjusted into a slurry of a certain concentration.
