Abstract

The invention provides a wet processing method for mica iron oxide. The method comprises the following steps: (1) adding a mica iron oxide raw material into a ball mill, adding water as a grinding medium, wherein solid content is allowed to be 55 to 60% in terms of the weight percentage of mica iron oxide, and adding 5 to 8% of a grinding aid; and (2) carrying out ball milling by using the ball mill in the step (1), wherein a ball-material ratio is 8: 1 to 10: 1, a rotating speed is set to be 300 to 500 r / min and ball milling time is 60 to 120 min, then carrying out drying at 30 to 40 DEG C in a vacuum drying box and then carrying out dispersion so as to obtian ultrafine mica iron oxide powder. Through optimization of the operation parameters of the wet processing method for mica iron oxide, the prepared mica iron oxide has a great amount of flaky structures, finer average granularity and a narrower granularity scope.

Description

technical field [0001] The invention relates to the technical field of mica iron oxide processing, in particular to a wet 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 and iron oxide red prepared by crushing, ultra-fine processing, and sorting are mainly used as fillers for anti-corrosion coatings. The current pulverization process of mica iron oxide is complex, the pulverization effect is not good, the particle size range is relatively wide, and the flake structure of mica iron oxide will be destroyed during the pulverization process. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to provide a mica iron oxide wet p...
