Hematite ore, the commonly iron ore used the industrial raw material for iron ore making, with certain magnetism, so most of the hematite process contains a magnetic link. According to the anhydrous medium, the magnetic extracting iron from hematite can be divided into dry magnetic separation and wet magnetic separation.3. Hematite ore gravity separation process. Hematite ore gravity separation process mainly includes coarse grain gravity separation process and fine grain gravity separation process . Coarse grain gravity separation process is a kind of hematite separation process used to treat the deposit with high geological grade (about 50 ), but the ore body with thin or multiple layers.
Characteristics of the iron ore processing technology in recent years. 1. Pre separation process (1) Pre separation of low grade magnetite ore. The successful development and application of big lump ore dry permanent magnetic separators and high efficiency magnetic drums (magnetic pulleys) have enabled the beneficiation of low grade magnetite ore to discard 10 to 30 of tailings in advance.Hematite recovery was feasible at a pH of around 3. In microflotation tests, the iron grade and recovery reached approximately 37 and 30 , respectively. These values increased in batch flotation circuits, specifically in the cleaner stage, the iron grade reached approximately 44 and the recovery was approximately 65 .

Iron ore beneficiation technology and process. 12 17 20 201 Views icon 0 . Iron ore is one of the important raw materials for the production of pig iron and steel in the iron and steel industry. There are many types of iron ore. According to the magnetic properties of the ore, it is mainly divided into strong magnetism and weak magnetism.The process of simultaneously roasting and magnetic separation was developed to treat the low grade siderite and hematite ores without adding any reductant. Effect of mass ratio of S to H (siderite ore to hematite ore) on the separation indexes of iron concentrate was discussed.
Nov 02, 2018 The following is an introduction to these four types of iron ore, magnetite, hematite, limonite and siderite. Iron ore property. Iron is widely distributed in nature (the crust), but since iron is easily combined with other elements to form various iron minerals (compounds), there is little natural pure iron in the earth’s crust.The combined iron ore processing technology only used for limonite, includes magnetization magnetic separation process, flotation strong magnetic separation process, gravity separation strong magnetic separation process, etc., which are used for the extraction of iron from limonite with relatively complex composition.
