The Development History of the Iron Ore Beneficiation Technology

The continuous promotion of the industrialization, urbanization and modernization projects has led to several results: the increasing demand for the iron ore, the gradually aggravating imbalance between supply and demand of mineral resources like iron ore, and the growing environmental pressure. How to realize the comprehensive utilization of the natural resources and recovery of the renewable resources will be the primary matter people should focus on during the process of constructing saving type society and sustainable economy.

As for the iron ore beneficiation technology in China, most mining machinery manufacturers have learned to adopt different beneficiation techniques to make the most of the resources and the equipment according to the various properties of the iron ores. Here experts from our company will list three technological development of the iron ore beneficiation production line and we can have a brief knowledge of the developing history of the domestic beneficiation technology.

First, in order to complete the grading and separating processes of the low grade magnetic iron ore or the magnetite, the Chinese ore beneficiation plants tend to adopt the multi-stage grinding procedure.

Second, when it comes to the ore beneficiation of the weak magnetite with very low ore grade, fine embedded granularity and complex mineral composition, we will choose the technological process of weak magnetic- strong magnetic- flotation.

Third, as for the paragenic ore consisting of many kinds of metals, there are various beneficiation methods such as the reverse flotation to multi-gradient magnetic separation type, weak magnetic-reverse magnetic separation- strong magnetic type and weak magnetic-direct flotation type etc.
