Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.
At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as fine as powder.
The iron ore jaw crusher is a new generation of crushing machinery newly developed by Machinery in combination with large scale crushing machinery manufacturers at home and abroad. It specializes in the crushing of iron ore and overcomes the hardness and variable nature of iron ore materials.
Iron ore dressing and crushing process According to the kind and characteristic of ore, there are many different processes for iron ore dressing. In general, ore dressing plant may use primary, secondary and tertiary crushing processes for crushing iron ore.
We recommend that you begin by screening the iron ore to separate fine particles below the crushers CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
Production Process of Iron Ore Generally, the processing of iron ore needs several processing stages, including crushing, grinding, ore beneficiation, concentrating, drying, etc. The equipments for iron ore beneficiation is consisted of Jaw Crusher, Ball Mill，Classifier, Magnetic Separator, Flotation Machine, Concentrator Machine and Dryer.
