WO2007115377A1 - Process for recovery of antimony and ...

A process for recovery of antimony and metal values from antimony- and metal value-bearing materials is provided. A coarse (typically >250-µm) concentrate of the antimony- and metal value-bearing materials is provided. The coarse concentrate is then subjected to a process for selective recovery of antimony in the form of solid antimony or an antimony containing solution.

27-07-2018  The process of reductive smelting of the antimonate concentrate on black antimony was carried out in an oven with silicate heaters in alundum crucibles with batches of charge of 100–150 grams. The content of impurities and the base metal in antimony was determined by chemical and atomic absorption methods.

Cupellation - Wikipedia

Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the ...

Lead Ore - an overview ScienceDirect Topics

Arsenic, antimony, and bismuth are three metalloids that usually occur together in association with copper, lead, tin, and gold ores. Bolivia is the only country in the world where bismuth is found in sufficient concentration to justify mining for bismuth alone, while in Morocco both arsenic oxide and metallic cobalt are recovered from a unique deposit of cobalt arsenide mineral, skutterudite ...

Antimony also is used as an alloy, because it hardens other metals. Alloyed with lead, it greatly improves the strength and hardness of lead. It also is used in semiconductors, diodes, infrared detectors, batteries and bullets. Antimony compounds are used in paint pigments, enamels, Limestone and pottery.

Antimony alloys are also used in batteries, low friction metals, type metal and cable sheathing, among other products. Antimony compounds are used to make flame-proofing materials, paints, ceramic enamels, Limestone and pottery. The ancient Egyptians used antimony, in

Antimony Sb - PubChem

Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However, there are companies in the United States that produce antimony ...

CHAPTER 5. POTENTIAL FOR HUMAN EXPOSURE

Antimony is also produced as a byproduct of smelting primary lead ores. Primary smelter outputs were 19,675 metric tons in 1992. Almost as much antimony is produced from scrap as from ore. Antimony produced from secondary sources is primarily derived from "old scrap," generally consisting of lead battery plates, type metal, and bearing metal.
