Very low grade Iron ore cannot be used in metallurgical plants and needs to be upgraded to increase the iron content and reduce the gangue content. A process adopted to upgrade ore is called Beneficiation. Iron ore is upgraded to a higher iron content through concentration. Iron ore is being beneficiated all round the world to meet the quality requirement of Iron and Steel industries. However, each source of Iron ore has its own peculiar mineralogical characteristics and requires the specific beneficiation and metallurgical treatment to get the best product out of it. The choice of the beneficiation treatment depends on the nature of the gangue present and its association with the ore structure. Several techniques such as washing, jigging, magnetic separation, advancedgravity separation and flotation are being employed to enhance the quality of the Iron ore.
Due to the high density of hematite relative to silicates, beneficiation usually involves a combination of crushing and milling as well as heavy liquid separation. This is achieved by passing the finely crushed ore over a bath of solution containing bentonite or other agent which increases the density of the solution. When the density of the solution is properly calibrated, the hematite will sink and the silicate mineral fragments will float and can be removed.
The extract the metal from ores, several physical and chemical methods are used. The method used depending upon chemical properties and nature of the ore from which it is to be extracted. It involves four main steps:
1. Crushing and grinding of the ore.
2. Concentration or dressing of the ore.
3. Reduction to free metal.
4. Purification or refining of the metal.

Hongxing is a iron ore machine manufacturer in China, and supplies rock crushers and grinding mills for ore beneficiation plant such as iron ore crusher, copper ore crusher, manganese ore crusher. Hongxing provides iron ore mining equipments for sale with best price in Australia, Brazil, India, Canada, USA, Ukraine, Liberia, Russia, Sweden, France, South Africa and other countries.
The most commonly used crushers and grinding mills in iron ore crushing and grinding process for iron ore mining are jaw crusher, cone crusher, hammer crusher and ball mill, ultrafine grinding mill, etc. In iron ore mining, miner usually choose a complete iron ore crushing plant for metallurgy. At present, the most popular iron ore production line consists of two jaw crushers. After beening crushed, the material will be transported for the magnetic separation, and then into the ball mill for grinding.
As the professional manufacturer of complete sets of mining machinery, such as classifier, Henan Hongxing is always doing the best in products and service.
