Indonesia is rich of mineral resources, which include coal, copper, gold, natural gas, nickel, and tin. Of these abundant minerals,tin output in Indonesia was ranked second after China. Because of the Government’s continued crackdown on illegal tin mining, small tin smelters received less tin ore. As a result, production of mined tin and tin metal was estimated to have decreased slightly. Tin mining industry development requires advanced technology and high performance tin ore processing equipment, including various types crushing machines.
The process of extracting tin from tin ore varies according to the source of the ore deposit and the amount of impurities found in the ore.Tin deposits in Indonesia are located in the gravel along streambeds and require the use of dredges or pumps to reach the ore. The ore in these deposits may contain as little as 0.015% tin by weight.
In tin ore processing operation, after extracted from mine, the raw tin ore mateirals will be delivered to a threestage crushing plant and reduced to about 12 mm followed by ball mill grinding to liberate the cassiterite (tin oxide) from the gangue, sulphideflotation to remove pyrite and any other sulphides, then concentration of the tin by a combination of hydraulic classification, gravity separation plant and fine tin flotation to produce concentrates acceptable to tin smelters.
Tin ore crushing is the first stage in tin ore processing operation;generally there are three crushing stage for tin ore size reduction, including primary crushing, secondary crushing and tertiary crushing. Between each crushing steps, there will be vibrating screen to separate different particle size, and belt conveyor to convey the materials to next stage. As for the specific projects, there will be customized crushing production line according to the ore deposit and properties.
The choice of crusher depends on the type and amount of material to be crushed. Gyratory and jawcrushers is usually used as primary crushers in mining and mineral processing operations today, although someoperations use impact crushers or other types of crushing machine. Cone crushers have been the most popular for fine crushing applications, although some mines use vertical impactcrushers for tertiary and quaternary crushing.
The main goal for the design of a tin ore crushing plant is to meetthe requiredproduction requirements, operateat competitive cost, comply with environmentalregulations, and gain maximized profits by lowest investment cost. In a standard tin ore crushing production line, several different types of crushing equipment are involved in tin ore processing plant, including primary jaw crusher, secondary impact crusher, cone crusher, mobile crusher etc.
