Antimony - Wikipedia
Production process. The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue minerals.

Bioleaching - Wikipedia
Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt
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
Metallurgy - Definition & Process | Principles of Metallurgy
The free elemental form of sulphur, arsenic, and antimony are removed as SO 2, AS 2 O3, and Sb 2 O 3, respectively. 4. Calcination: The process of heating a concentrated ore in the absence of air to melt the ores is called calcination. This process is done for carbonate ores. ZnCO 3 → ZnO + CO 2. CaCO 3 → CaO + CO 2. Al 2 O 3.2H 2 O → Al,
Chemistry: Properties and Application of Sb-Antimony | by,
Sep 15, 2018· Antimony is found in trace quantities in nature but is chiefly obtained from mineral ores such as valentinite (Sb2O3) and stibnite (Sb2S3). Pure refined antimony is used to make semiconductor,
What is the Process of Metallurgy - A Plus Topper
Dec 03, 2020· In this process the ore is heated very strongly in the absence of air, keeping the temperature below its melting point so that volatile impurities are driven off. Examples: (i) Oxide ores are calcined to remove moisture and other volatile impurities. Al 2 O 3. 2H 2 O → Al 2 O 3 + 2H 2 O (ii) Carbonate ores are calcined to expel carbon dioxide.
silver processing | Britannica
A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.
Gold Smelting & Refining Process
Feb 28, 2016· Other process used for a long time is the Wohlwill Process and is considered as the second part of the Miller process due to refine its product. This is an electrolytic process based on the dissolution of gold in an acid bath prepared with chlorine gas and hydrochloric acid. The final product is a gold cathode with 99.99% purity.

How lead is made - material, used, processing, product,
Lead is extracted from ores dug from under-ground mines. More than 60 minerals contain some form of lead, but only three are usually mined for lead production., it is usually found with traces of other metals in it, including silver, copper, zinc, cadmium, and antimony as well as arsenic. Two other, The flotation process collects the,

Polonium. Polonium is a radioactive, extremely rare semi-metal. It is reactive, silvery-gray, it dissolves in dilute acids, but it is only slightly soluble in alkalis. it is fairly volatile: about half of a sample of it will evaporate within 3 days (unless it is kept in a sealed container).
