The TISCO Yuanjiacun Mine is a large iron ore deposits, maintain the reserves is over 13 billion tons. Deposit ore types can be divided into the oxidation of iron ore and native iron ore. Oxidation of iron ore can be divided into the quartz type mirror (network) iron ore type, amphibole type and type conglomerate; native of iron ore can be divided into the quartz and amphibole type type. Each ore based iron taste different, there are points of lean iron ore and sub-depleted iron ore. As the Yuanjiacun iron ore type is more, structure, structure complex and the various mineral disseminated coexistence fine, causing great difficulty to the beneficiation process, resulting so far has not been a comprehensive development and utilization.
Quartz and amphibole multi-element chemical analysis of the oxidation of iron ore and iron phase analysis results. The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer crusher, impact crusher, roll crusher, crusher compound. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. Two oxidized ores of iron ore Yuanjiacun metallic minerals are mainly illusion of hematite semi martite, hematite, limonite, magnetite, pyrite specularite: gangue minerals are quartz, amphibole minerals (through idle stone, mafic amphibole, a small amount of iron amphibole) and calcite. The two oxidized Owers are banded structure-based, there is a fine-coarse-grained gangue minerals embedded in the metallic minerals striped cloth, there is a fine-coarse-grained metallic minerals disseminated in a gangue mineral bands. The grain size of the metallic minerals and gangue minerals are very fine. Quartz-type ore metal ore grain is more than 0.044 mm or less, a part of the very fine particle size in the following O.O1mm; the gangue minerals coexistence thicker than the metallic minerals, and more, including a considerable number of particle size less than 0.05 mm in 0. 01 mm below. Amphibole mineral ore grain is a little thicker than the quartz-type ore mineral amphibole more fiber structure, and the fiber diameter is usually only child micron to cause difficulties to the magnetic beneficiation dissociation.
