Future development trend of non-metallic mineral powder processing
PTMS magnetic separation
How is magnetic separation used in everyday life?
Common non-metallic minerals of reality include graphite, quartz, kaolin, mica, talc, diatomaceous earth, smectite, wollastonite, barite, rutile, bentonite, fluorite, sillimanite, andalusite, blue Spar, tourmaline, etc.
There are many factors affecting non-metallic minerals. Most people now pay attention to structure, purity or chemical composition, particle size and shape, surface or interface physicochemical properties.
For non-metallic minerals, purity in many cases refers to its mineral composition, while non-chemical composition is precisely the mineral composition that determines the structure of the mineral. There are many non-metallic minerals with similar chemical composition, but the mineral composition and structure are far apart, so their function or application properties are very different. For example, quartz and diatomaceous earth, although the chemical composition is silica, the former It is a crystalline structure of silicon oxytetrahedrons, which are amorphous structures with complex structures, and therefore their application properties or functions are very different. The influence of mineral composition, chemical composition and structure on the function of non-metallic mineral materials is also related to the purity of minerals. In many cases, in order to fully fluoresce the function of non-metallic mineral materials, mineral raw materials must be beneficiated and purified, especially when there are many impurities in the mineral raw materials, and such impurities have an adverse effect on a major function of the non-metallic mineral materials. . Therefore, the beneficiation and purification technology is very necessary for the function of non-metallic mineral powder. In the 21st century, both the emerging high-tech and new materials industries, environmental protection industries and traditional industries will place higher demands on the purity of non-metallic mineral powder materials. With the improvement of the purity requirements of non-metallic mineral powder materials, the difficulty of selecting and purifying technologies will also increase. In addition, the depletion of resources, the improvement of resource comprehensive utilization requirements and the increasing environmental protection requirements will also increase the selection and purification technology. Difficulty. Therefore, fine-grain beneficiation purification and selection technology, comprehensive utilization technology or no tailings processing technology will become the main development trend of future non-metallic ore purification technology.
When some of our enterprises develop resources and projects, they often do not pay attention to carefully study the market, how to meet market requirements from product functions, and adapt to the needs of related industries. How to mine and enhance product functions and application performance through application research, how to Pay attention to the protection of the ecological environment during the processing. The development of modern high-tech and new materials is premised on higher technological content, lower environmental load and more adaptable to the needs of social development. Non-metallic mineral powders and materials are no exception. Only non-metallic mineral powders or deep-processed products that have clear functions or outstanding functions and can meet the technical progress and industrial development requirements and environmental protection requirements of relevant application fields can win a stable market. Therefore, the future development trend of non-metallic mineral powder materials will be cross-distribution, fusion mineralogy, powder processing, materials science and related fields of different fields, collaborative research, continuous exploration and upgrading of non-metallic mineral powder products and applications Performance, promote technological advancement and industrial development in related application areas.
