Introduction

Iron ore is an important raw material for iron and steel production enterprises. Iron is gradually selected from natural ore (iron ore) by crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. It is a mineral aggregate containing iron or iron compounds that can be economically used. Any ore containing iron that can be economically used is called iron ore. There are many kinds of iron ores, mainly magnetite (Fe₃O₄), hematite (Fe₂O₃) and siderite (FeCO₃) for iron making. There are two characteristics of China's iron ore resources: one is that there are many lean ores, the reserves of which account for 80% of the total; the other is that there are more complex ores with multiple elements. In addition, the ore bodies are complex; some of the lean ore deposits are hematite and the lower part is magnetite. In view of the existing characteristics of iron ore in China and the higher requirements for iron concentrate in the iron and steel industry, new challenges have been posed to the Chinese ore dressing workers. Therefore, China's metallurgical mine beneficiation technology has a deeper development requirements, followed by the further improvement of mineral processing equipment.

Iron ore Processing technology

Iron ore beneficiation can be divided into several different processes according to the type and nature of ores. Ore dressing plants usually use coarse crushing, medium crushing and fine crushing three stages crushing process to crush iron ore. In the iron ore crushing production line, in order to improve the production efficiency of the iron ore crusher and reduce the production cost, it is often necessary to crush the iron ore as fine as possible and crush the iron ore to the smallest particle size in order to achieve more crushing and less grinding. After the practical experience of iron ore processing and user feedback, the industry believes that the cone crusher for fine crushing of iron ore is the best. Specific process of iron ore crushing production line: iron ore is evenly sent to jaw crusher of iron ore crusher by vibrating feeder for coarse crushing, coarse crushing materials are sent to cone crushing by belt conveyor for further crushing, crushed materials are transported to vibrating screen for screening, to meet the requirements of particle size of finished materials through Belt conveyor conveys to the finished product stack; materials that do not meet the size requirements of the finished product are returned from the vibrating screen to be crushed or finely broken cone, forming a closed-circuit cycle. The particle size of iron ore pulverizer can be combined and graded according to the needs of users.
Iron ore is an important raw material for iron and steel production enterprises. Iron is gradually selected from natural ore (iron ore) by crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. In theory, any ore containing iron or iron compounds can be called iron ore; however, in industry or commerce, iron ore is different from manganese ore, iron ore not only contains iron, but also must have the value of utilization. After being mined out of the mine, the iron concentrate is treated with mineral processing equipment into about 65% iron concentrate, which is then taken to smelt into sponge iron, and then steelmaking.

Application fields Through the deep processing, Iron ore can be widely used in the following industries.
