converting metal from antimony ores - jackhiggins.co.za
Ores of metals including antimony, copper, nickel, and zinc are often compounds of sulfur. The metals are conventionally extracted by converting the ore into oxides by roasting at high temperatures, during which carbon and sulfur dioxide are emitted. The oxides are then converted to metals by heating them at temperatures over 1000°C. 05-May

from antimony and other nonferrous metal from antimony ore is rough of antimony leaching from oxidizing-converting slag of Pb Flotation concentration of the sulfide antimony-arsenic The technology of concentration of the sulfide antimony-arsenic of the sulfide antimony-arsenic gold-bearing ore of Ores of Nonferrous Metals),
Extraction of Antimony
Chemically pure antimony has been prepared by converting antimony trichloride, purified by distillation, into chlorantimonic acid, which, after purification by recrystallisation, is hydrolysed to antimonic acid. The antimonic acid is finally reduced to metal by fusion with potassium cyanide.

Conversion of Ore into Metal Oxide
To convert the concentrated ores into metal oxides, two processes are used. calcination (heating in inadequate quantity of air) and roasting the ore (heating in adequate quantity of air). Calcination:Carbonate ores are heated in absence of air. The absence of air and heat converts the CO3into CO2and O.
Direct sulfide electrolysis extracts metal using less energy
Ores of metals including antimony, copper, nickel, and zinc are often compounds of sulfur. The metals are conventionally extracted by converting the ore into oxides by roasting at high temperatures, during which carbon and sulfur dioxide are emitted. The oxides are then converted to metals by heating them at temperatures over 1000°C.

Metal Converter - The Calculator Site
Use this metal conversion tool to convert between different units of weight and volume. Please note that this type of conversion requires a substance density figure. A list of some common metal density approximations is provided below.
antimony | Definition, Symbol, Uses, & Facts | Britannica
The metal can also be obtained by conversion of stibnite to the oxide, followed by reduction with carbon. Sodium sulfide solutions are effective leaching agents for the concentration of stibnite from ores. Electrolysis of these solutions produces antimony. After further purification of the crude antimony, the metal, called regulus, is cast into cakes.
The exposure to and health effects of antimony
Antimony may enter the environment as a consequence of mining and processing of its ores and in the production of antimony metal, alloys, antimony oxide, and combinations with other substances. Antimony released from smelters may remain in particulate quantities in the air, some of which reaches the soil during rainfall where it attaches ...

concentrating antimony ores - frontemare.eu
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.
Chemie der Erde - stuff.mit.edu: students portal
The liquated product, called crude, liquated or needle antimony, is sold as such for applications requiring antimony sulfide, or is converted to metallic antimony by iron precipitation or careful roasting to the oxide followed by reduction in a reverberatory furnace.
Manufacturing Process of Copper - ThoughtCo
Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.
