“…The method of processing antimony concentrates [23] formed as an intermediate product of lead production containing 47.77 mass % Sb and 0.17 mass % As is aimed at obtaining metallic antimony with a low arsenic content at the first stage of reduction melting. To do this, the authors suggest melting antimony concentrate with sodium Na + or lead oxide PbO.…”

The article presents the results of scientific developments in the field of pyro-and hydrometallurgical processing of antimony-containing mineral and technogenic raw materials. Important industrial antimony products are metallic antimony and antimony trioxide of various grades. Methods of reducing melting and sulfide-alkaline leaching of antimony sulfide concentrates to obtain metallic antimony and antimony trioxide are discussed, and methods of refining antimony from impurities are also analyzed.

“…Terlikbayeva et al [88] developed, in lab-scale, an arsenic removal route from a sodium hexahydroxoantimonate (mopungite) concentrate containing 0.34% arsenic during the reduction smelting process for production of antimony with low arsenic concentration 0.07-0.1 wt%. In this process, smelting-refining of antimony concentrate was carried out via addition of sodium plumbite (Na2PbO2) or lead oxide (PbO) which oxidized arsenic Terlikbayeva et al [88] developed, in lab-scale, an arsenic removal route from a sodium hexahydroxoantimonate (mopungite) concentrate containing 0.34% arsenic during the reduction smelting process for production of antimony with low arsenic concentration 0.07-0.1 wt%.

“…Direct reduction of sodium antimonate to metallic antimony was achieved, and arsenic deported to the slag phase [88]. In 2021, Li et al [89] proposed removal of arsenic upstream of the conventional refining process (i.e., directly from ATO, before charged into the reduction smelting furnace).…”

Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology selection for a greenfield plant is a significant and delicate task to maximize the recovery rate of antimony and subsequently precious metals (PMs), mainly gold, from the concentrates. The current paper reviews the conventional pyrometallurgical processes and technologies that have been practiced for the treatment of antimony concentrates. The blast furnace is the most commonly used technology, mainly because of its adaptability to different feeds and grades and a high recovery rate. In addition, several other more environmentally friendly pyrometallurgical routes, that were recently developed, are reviewed but these are still at laboratory- or pilot-scales. For example, decarbonization of antimony production through the replacement of carbonaceous reductants with hydrogen seems to be feasible, although the process is still at its infancy, and further research and development are necessary for its commercialization. At the end, available refining methods for removal of the most important impurities including arsenic, sulfur, lead, iron, and copper from crude antimony are discussed.

“…Due to the lack of practical and economical treatment technology, arsenic-alkali residue produced by more than 95% of the enterprises in the smelting industry can only be stored in warehouses, exceeding 500000 tons. The clean utilization and harmless disposal of arsenic-alkali residue is the key factor in determining the sustainable development of the smelting industry [3]. The traditional arsenic-alkali residue treatment process is mainly wet treatment, and the arsenic in the arsenic-alkali residue is produced by sodium arsenate but alkali as sodium carbonate (or sodium hydrogen carbonate), meanwhile the resource utilization rate is low and secondary pollution will be easy to occur.…”

Arsenic-alkali residue is a kind of waste residue produced by removing the arsenic with alkali in the process of refining crude antimony. It is basically stored in the warehouse due to the lack of practical and economic treatment technology. In order to achieve clean utilization and harmless disposal of arsenicalkali residue, a new process of the clean utilization technology of arsenic-alkali residue with Sb efficient enrichment and As conversion stabilization was proposed. Compared with the traditional process, the new one can significantly reduce the As leaching concentration of curing object, and the unit treatment cost will be reduced by 50%. Herein we present a case of industrial application of the clean utilization technology.
