The principal ore minerals of antimony are stibnite and jamesonite, but it can also be a byproduct of certain other minerals. Eighty percent of the world's antimony is produced from two types of deposits — carbonate replacement deposits and gold-antimony epithermal deposits. There are two types of the ore, oxide and sulfide . The […]
In this work, a two-step vacuum metallurgy method was proposed to produce Sb2S3 from complex lead-antimony sulfide ore.

China is the biggest antimony ore producer but production has declined to 40,000 tons in 2023 from 61,000 tons in 2020 as a result of falling ore grades and more stringent environmental requirements.
In 2023, after four years of decline, there was growth in the global antimony ore and concentrate market, when its value increased by 2.4% to $1.9B. In general, consumption, however, recorded a deep reduction. Over the period under review, the global market hit record highs at $4.4B in 2012; however, from 2013 to 2023, consumption failed to regain momentum.

Antimony is an important mineral commodity used widely in modern industrialized societies. The element imparts strength, hardness, and corrosion resistance to alloys that are used in many areas of industry, including in lead-acid storage batteries. Antimony's leading use is as a fire retardant in safety equipment and in goods, such as mattresses.
The African antimony ore and concentrate market skyrocketed to $11M in 2023, rising by 37% against the previous year. In general, consumption, however, continues to indicate a abrupt contraction. The level of consumption peaked at $40M in 2012; however, from 2013 to 2023, consumption stood at a somewhat lower figure.
Antimony is mainly sourced from stibnite ore and as a byproduct of lead and copper smelting. Antimony's unique properties make it invaluable in numerous applications, from fire retardants to alloys.
