“…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). In their experiments, they mixed ATO with pyrite and conducted a two-stage process: (1) heating the mixture up to 550 The antimony recovery rate of >94% and arsenic removal rate of ~93% were obtained under a set of experimental conditions (5 wt% pyrite addition, 90 min holding time, and air flow rate of 200 mL/min).…”

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.
