Processing method of mica iron oxide

Abstract

The invention provides a processing method of mica iron oxide. The processing method of the mica iron oxide includes the following steps that, (a) raw materials are broken; (b) the materials in the step (a) are subjected to ball-milling through a ball mill, and overflow generated after classification of a spiral classifier is fed into a first hydrocyclone for the first time of separation; (c) a second hydrocyclone is used for performing the second time of separation; (d) the third time of separation is performed in a third hydrocyclone, and fine grinding is further performed; (e) the overflow separated through a fourth hydrocyclone is iron oxide red, settled sand of the fourth hydrocyclone is iron oxide grey crude products, and the iron oxide grey crude products are concentrated through table concentrators at two times; and (f) concentration, dewatering and drying are performed on iron oxide grey and the iron oxide red, and iron oxide grey finished products and iron oxide red finished products are obtained. By means of the processing method of the mica iron oxide, prepared mica iron oxide products are large in content of sheet structures and smaller in average particle size, the particle size range is small, the purpose of producing the iron oxide red and the iron oxide grey at the same time can be achieved, and industrial production can be easily achieved.

Description

technical field [0001] The invention relates to the technical field of mica iron oxide processing, in particular to a processing method of mica iron oxide. Background technique [0002] Mica iron oxide is a special iron ore in nature with ferric oxide as the main chemical composition. Its crystallization state is similar to mica, and its structure is scale-like, gray-black, with metallic luster. Due to its unique scaly structure, iron oxide ash (light gray or dark gray) and iron oxide red (rust red) prepared by crushing, ultra-fine processing, and sorting are mainly used as pigments and fillers for anti-corrosion coatings. The traditional mica iron oxide crushing process is complicated, the crushing effect is not good, the particle size range is relatively wide, and the sheet structure of mica iron oxide will be destroyed. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to provide a method for pr...
