antimony ore oxide process

Antimony | ToxFAQs™ | ATSDR

Antimony ores are mined and then mixed with other metals to form antimony alloys, which are used in lead storage batteries, solder, sheet and pipe metal, bearings, castings, and pewter. Antimony oxide is an antimony compound that is added to textiles and plastics to prevent them from catching fire.

Generally, the separation process including manual, gravity, flotation separation, most of the time, use unite processes . No matter oxide ore or sulfide ore, they all heavier than matrix, so we could choose gravity separation for most of the antimony ore . For the ore with thick grain, manual separation is more useful .

Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.

General Discussion on Smelting.—Practically all of the shaft furnaces mentioned for the volatilization process are of the same type, except with minor differences in details as to the form of the grate- bottom and as to size. The ideal ore for treatment in such furnaces is one containing antimony from 15 to 25 per cent.; ore above 40 per cent.

Antimony Trioxide

General Information. Antimony trioxide (Sb 2 O 3) is a slightly soluble, white crystalline powder. [] It is produced by smelting antimony-containing ores [] or reacting antimony trichloride with water. [] Antimony is not abundant in the earth''s crust. [] Antimony trioxide may also be referred to as diantimony trioxide (DAT), antimony oxide, or in manufacturing as antimony white. []

Antimony Trioxide | Applications and Specifications

Antimony oxide can be prepared by two processes, the direct and the indirect process. Indirect process. In this process, antimony metal or ores is melted in a furnace to give ATO vapors. The vapors are quenched with air and cooled to convert the vapor to white powder. These powders are further filtered to give antimony trioxide powder.

Antimony Mining

Many minerals contain antimony; however, stibnite and antimonial lead ores are the main sources of the metal. Stibnite (Sb2S3) and its alteration oxide, stibiconite (Sb 3+ Sb 2 5+ O 6 (OH)), were the only minerals mined in Arkansas for this metal. Stibnite is steel-gray, has a relatively high specific gravity (4.6), and has a metallic luster.
