Professional Development And Production Of Hematite Mineral Processing Equipment
Professional development and production of hematite mineral processing equipment
The chemical composition of hematite is Fe2O3, the crystal belongs to trigonal system of oxide minerals. Western name is derived from the Greek "blood" means, means that this mineral is often red. It is an iron oxide , is the main ore mineral of iron, other metal instead of iron status, but the iron is still the most important metal.
One of the most economically important mineral is hematite. Only a few places, we can find the perfect metal flash rhombohedron crystal hematite, but the more the case, the crystal is often flat side, and even the formation of laminated, some sample plate clusters like a rose, called the Iron Rose. sometimes scaly aggregates, called specularite. all of these crystalline hematite good variant is black, but has the streak , that is, the mineral powder colors are red, the so-called kidney-shaped iron ore is the red, kidney-shaped iron ore is a collection of some of the radial, kidney-shaped surface. Red is the vast majority of crystalline morphology . Earthy red iron ore color ocher is this a red earthy hematite, it was as a pigment.
Hematite is widely distributed minerals in which all kinds of rocks, finely dispersed granular appearance in many igneous rocks, in exceptional circumstances, a huge block in the regional metamorphic rocks.
In red sandstone, hematite, quartz grains of the cement and the rock color is worth mining. To economically, it must contain thousands of tons of hematite, which may reserves large-scale sedimentation caused Precambrian strata , that have a lot of this iron ore, they are usually silicon impurities.
Rich iron ore, iron content of at least 50%, which is due to the rain silica leaching and rich integration of these high-grade ore, which is the source of iron in the world, but its reserves are dwindling. To compensate for this deficiency, Mining companies are turn their attention to the original iron to build the so-called iron quartzite. this rock only contains 25-30% iron, but it has enormous reserves mechanical way, you can make low-grade iron ore iron mineral enriched . So iron quartzite will be long-lasting iron ore resources.
In every continent , you can find and exploitation of large hematite deposits. In 1961, the Soviet Union replacing the United States become the largest producer after the United States, France, Canada, China, Sweden and Australia in the United States since the late 19th century. The largest producer of minerals is in the Precambrian rocks of the Great Lakes region.
The chemical composition of hematite is Fe2O3, the crystal belongs to trigonal system of oxide ore, and some called specularite, mica, hematite, ocher, was reddish-brown, gray, black iron or cherry red, magnetic susceptibility X = 88-220 10-8m3/kg, are weakly magnetic minerals, common in low magnetic field strength of the magnetic separator can not be sorting hematite mother hematite, ocher, was reddish-brown, gray, iron, black or cherry red than the magnetic susceptibility X = 88-220 10-8m3/kg are weakly magnetic minerals, common in low magnetic field intensity magnetic separator can not be sorting hematite.
Jiang Su Zhongbo processing machinery is professional development and production of hematite mineral processing equipment, used for a variety of grade hematite mineral. Strong magnetic field of dry-type permanent magnet roller high gradient magnetic separator, limonite processing equipment, hematite mineral processing equipment, The equipment used for the beneficiation of limonite and hematite mineral. The family of devices for the separation of low grade weak magnetic limonite, hematite, once to improve the grade of 3-7%, a good solution has always been low-grade limonite, hematite can not be into the smelting furnace, difficult to sell low-grade ore found a way out, can generate considerable economic benefits. The device has high return on investment, less investment and quick project.
