Ilmenite beneficiation method and equipment

Abstract

The invention provides an ilmenite beneficiation method and equipment, and is suitable for comprehensive utilization of low grade ilmenite resources. The method and the equipment provided by the invention can be used for separating materials by fully using three kinds of physical differences of useful components in ilmenite magnetic iron and ferrotitanium and useless gangues, such as magnetism, density and surface hydrophilicity, as well as the property of the stage degree of dissociation. In the whole separating process, by using a magnetic-gravity separation-flotation combined process, the magnetic iron which is the strongest in magnetism is separated by using a magnetic separating method firstly, and then the ferrotitanium is selected by using a method of gravity separation combined with strong magnetic combined flotation. In the whole separating process, a graded ore grinding and graded beneficiation method is adopted, and in the process of separating the ferrotitanium, ore is secondarily ground, so that the ferrotitanium containing part of impurities after strong magnetism in the first stage is further dissociated, and therefore, relatively good beneficiation indexes are obtained.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to an ilmenite beneficiation method and equipment, which are suitable for comprehensive utilization of low-grade ilmenite resources. Background technique [0002] The quality of iron concentrate is directly related to the cost of blast furnace smelting, and domestic and foreign mineral processing circles regard improving the grade of concentrate as the focus of scientific research. Most ores need grinding and beneficiation, and fine-grained iron concentrate is known as the leading product in the iron ore industry; currently its production is mainly based on wet separation. The disadvantage of wet beneficiation is that a large amount of water resources are required in the production process, and the discharged wastewater seriously pollutes the environment; tailings storage still requires a huge investment in the construction of tailings ponds, and the existence...
