Iron ore types can be divided into two categories: natural and industrial. The natural type is a combination of ore minerals according to the material components, structure and structure of the ore; the industrial type is an ore type divided according to the different methods and processes of ore dressing and smelting in the industry.
Machine types: Dry Magnetic Separator and Wet Magnetic Separator. ① Dry Magnetic Separator: Separate dry magnetic minerals, such as crushed iron ore. ② Wet Magnetic Separator: Suitable for magnetic pyrite, roasted ore, ilmenite, coal ores, and other materials with a particle size of less than 3 mm. 3.
In order to improve the efficiency and production capacity of ore dressing and meet the smelting production requirements of iron and steel plants, appropriate and technology should be selected according to the different properties of different iron ore during beneficiation to achieve better beneficiation effects.

Preparation before Ore Dressing The preparation usually consists of two stages: crushing and mineral grading. In order to separate useful minerals from ore, the ore should firstly be crushed. Sometimes in order to meet the requirements of the material size of the subsequent work, it is necessary to add a certain crushing operation.
There are generally five requirements for iron concentrates: (1) High iron content. The iron content of magnetite concentrate should be more than 65%, hematite concentrate should be more than 60%, and limonite concentrate should be more than 50%. The fluctuation of iron content is less than ±0.5%. (2) Low moisture content.
