Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. Additionally, the protection scope of the present invention should not be limited only to the following specific structures or components or specific parameters.
[0024] Ilmenite is composed of magnetic iron, ilmenite and gangue, because there are multiple components in the mineral, so there are different degrees of dissociation. The main difference between magnetic iron, titanium iron and gangue is that magnetic iron has strong magnetism, titaniu...

Provided is an ilmenite beneficiation method and equipment, which are suitable for comprehensive utilization of low-grade ilmenite resources. The present invention makes full use of the useful components of ilmenite, magnetic iron and ferro-titanium, and the three physical differences of magnetism, density, and surface hydrophilicity of the useless gangue, as well as the stage dissociation degree and other physical properties to process the material. sorting. The entire separation process adopts the combined magnetic-gravity-flotation process. First, the magnetic iron with the strongest magnetism is selected by magnetic separation, and the most magnetic iron is selected by re-election combined with strong magnetic flotation. ferro-titanium. The stage-by-stage grinding and stage-by-stage beneficiation methods are adopted in the whole separation process, and the secondary grinding is adopted in the process of separating titanium ferro-titanium to further dissociate the ferro-titanium containing some impurities after a period of strong magnetic field, thus obtaining Better beneficiation indicators.
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...
