It is the rock from which metallic iron can be economically extracted. iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (fe). the iron ore, usually, very rich in iron oxides (fe3o4 and fe2o3). iron ores are mostly dark grey to rusty red in color and high specific gravity. two main types.
Iron minerals are homogeneous natural solids (molecules) with an ordered atomic structure and a defined chemical composition. for example, hematite (fe 2 o 3) and magnetite (fe 3 o 4) are iron minerals. the ore treatment process is a set of physical techniques that releases and separates mineral grains from the ore to make useful mineral.
Magnetic separation is the main iron ore dressing methods. common iron ore magnetite (belongs to the strong magnetic minerals), hematite, limonite, specularite, siderite (belong to weak magnetic minerals) and so on, they are raw materials of iron and steel industry, our country's iron ore grade is low, impurities content mostly is higher, therefore, more than 80% magnetic separation is.
