antimony ore impact

Antimony: will China continue to control supply?

Once mined, antimony ore needs to be processed into metal ingots, which are then used to produce antimony xide for flame retardants. This entire processing capacity is predominantly located in China. However, the new roaster plant being built in Oman, according to the company in charge of the project, Strategic and Precious Metal …

In this series of tests, batch pressure leach tests were conducted with a low-arsenic, low-antimony concentrate (Concentrate C) blended with antimony sulphide (0 to 12%). These concentrate blends were added to the laterite ore at about 23.0% of the total solids to provide the acid required for the leaching of the concentrate and the laterite ore.

RELEVANCE TO PUBLIC HEALTH

Antimony (Sb) is naturally present in the earth's crust at levels of about 0.2–0.3 mg/kg (ppm), but these levels vary by location (Telford et al. 2008). It can be transported into streams and waterways from natural weathering of soil, as well as from anthropogenic sources (EPA 1979; Mok and Wai 1990). Antimony enters the environment during the …

Economic geology and environmental characteristics of antimony …

Antimony is commonly listed as a critical mineral, particularly in the United States and European Union [1]. Its criticality, or supply risk, is derived from a combination of economic vulnerability, disruption potential of supply, and trade exposure [2].Disruption potential relates a country's ability and willingness to supply a commodity.

INTRODUCTION. Antimony (Sb) (atomic number 51; atomic mass 121.75 g/mol; density 6.684 g/cm 3; melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3).The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure antimony …
