subject: Unfully Development And Utilization Of The Iron Ore [print this page] The TISCO Yuanjia Village belongs to large-scale iron ore deposit maintaining reserves of more than 13 billion tons. There are many types of ore which can be divided into the oxide ore and native iron ore. Oxidation of iron ore can be divided into a type of quartz, iron ore microscopy (red) type, amphibole, and conglomerate type; native iron ore can be divided into quartz-and amphibole type. Due to each different grade of ore in accordance with iron, and it can be divided into depleted iron ore and depleted iron ore points. Because of its many types of iron ore, structure and construction are complex, various mineral dissemination size is tiny, and caused great difficulty for the beneficiation of the flotation machine, resulting in an incomprehensive development and utilization.
Metallic minerals are two kinds of oxidized ores in Yuanjia Village martite, which are mainly composed of halfillusion of hematite, hematite, specularite-based, followed by magnetite, limonite, pyrite,etc.; gangue minerals are mainly quartz, the mineral of the amphibole (tremolite, magnesium
and iron amphibole, a small amount of iron amphibole) and calcite. These two kinds of oxide ores are mainly banded structure , disseminated metallic minerals stripe fine gangue minerals disseminated in the gangue minerals with fine metallic minerals . The grain size of metallic minerals and gangue minerals are very fine.The metal mineral grain in the quartz-type ore are mainly under 0 044 mm F, part of the fine particle size under 0.01 mm; the granularity of gangue mineral grain is thicker than the metal minerals, mostly are under 0.05mm, of which a considerable number of particles are under 0. 0I, mm. The granularity of amphibole ore is a little thicker than the quartz-type. But the amphibole ore possesses more fiber structures , and only a few microns, which usually results in difficult dissociation.
