Antimony is finding use in semiconductor technology for making infrared detectors, diodes and Hall-effect devices. It greatly increases the hardness and mechanical strength of lead. Batteries, antifriction alloys, type metal, small arms and tracer bullets, cable sheathing, and minor products use about half the metal produced. Compounds taking up the other half are oxides, sulfides, sodium antimonate, and antimony trichloride. These are used in manufacturing flame-proofing compounds, paints ceramic enamels, glass, and pottery.
Antimony is a very kind of important metal in the global economy with the annual output of 50 tons .And the main materials are mainly from China, Russia, Bolivia and South Africa .And the exploration of antimony need the crusher and grinding mill and we company will export large amount of crusher and grinding mill annually .And the world storage of antinomy is over 5 million tons and there also have a antinomy bed in Finland.
Antimony, while not abundant, occurs in over 100 minerals; 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. “New scrap,” which is derived from drosses and scrap generated during fabrication, constituted 8.6% of the secondary antimony in 1987 (Llewellyn 1988). Secondary antimony is chiefly consumed as antimonial lead; a small percentage goes into the production of other lead- and tin-based alloys.Antimony trioxide is produced by oxidizing antimony sulfide ore or antimony metal in air at 600-800!a
In this process, the antimony ore is heated in a crucible ore verberatory furnace in a reducing atmosphere. High-grade sulfide ores can also be reduced to the metal by iron precipitation, a technique in which the antimony ore is heated with iron scrap, which replaces the antimony. High-grade oxide ores are reduced with charcoal in a reverberatory furnace. An alkaline flux is used to reduce volatilization losses, which may be as high as 12-20X. The method of choice for low-grade sulfide ores is volatilizing roasting. In this process, the ore is heated to about 5OO”C, and the amount of oxygen is controlled, so that the Antimony Smelting Machine trioxide formed is volatilized and then recondensed.Intermediate-grade sulfide or oxide ores are generally handled by smelting. The impure metal may be refined by pyrometallurgical techniques or electrolysis. For further details on antimony mining, ore processing, recovery, and refining, see Carapella or Herbst et al.
Antimony crushers, including jaw crusher, ball mill, impact crusher and cone crusher, are widely used in the whole antimony mining process. And mobile antimony crushers are the good equipment choise to most of the animony ore concentrators. Primary antimony crushing is used twice in the antimony process. Our company would supply the most suitable antimony ore crushers and antimony mining mills for you.
