Antimony has the characteristics of oxidation resistance and corrosion resistance, which is widely used in various industrial fields, such as flame retardants, battery alloy materials, biomedicine, and plastic stabilizers [1, 2].Stibnite is the most important mineral raw material for antimony beneficiation and smelting [].In mining production, …
The antimony layer is then removed, and the puri-fied antimony is dissolved in a more dilute mineral acid solution. Overall, leaching with mineral acids remains one of the most established methods for extracting antimony metal [14,15]. Alkaline leaching involves using alkaline solutions to dissolve antimony. Sodium hy-
This process contains multiple steps including desulfurization in the fluid-bed roaster, sintering after burden, reduction smelting of calcine with coal in a BF to produce …
There are many varieties of antimony ore, including antimony ore, antimonyite, antimony ore, antimony ocher, etc.The selection of antimony ore beneficiation processes is not unique.

Gold beneficiation projects worldwide have demonstrated the successful implementation of advanced techniques. One notable case is the mine in Yanacocha, Peru, the largest gold mine in Latin America. This project illustrates the application of cyanidation and other modern processes, alongside stringent environmental protocols.
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 …
In both cases, these couplings can be used in conjunction with hydride generation (HG) to improve sensitivity. [24] The successful separation by HPLC-ICP-MS of Sb III, Sb V and TMSb has already ...
The separation of antimony and bismuth in copper electrorefining is somewhat difficult and costly. An ion-exchange technique for the removal of the metals from the electrolyte has been practiced recently, although the metals recovered require further processing. Sumitomo Metal Mining has developed a process to recover antimony and bismuth …
The mining and smelting of antimony will inevitably have a significant impact on the surrounding and downstream farmlands of the mining area, Therefore, it is necessary to understand the pollution ...
They are basically a mixture of two or more substances. Interestingly, mixtures tend to also come in different forms. Therefore, there are several types of separation techniques that are used in segregating a mixture of substances. As for the need for separation, it is usually done to remove all the unwanted materials and obtain useful components.
Mining residues often contain embedded antimony, posing environmental risks. Deep eutectic solvents, known for being low in toxicity, cost-effective, and environmentally friendly, present a promising avenue for sustainable antimony extraction.
The techniques used in antimony mining vary based on the deposit. Open-pit mining is commonly used for extracting larger deposits, while underground mining might be employed for deeper ore bodies. The extraction process typically involves crushing and grinding followed by gravity separation or flotation to concentrate the ore. It is then ...
Thus, extracting and recovering these metals from copper production has become increasingly important. In recent years, several methods have been tested for removing these impurities from ...
