Combined mineral separation and purification method for kaolin ore or kaolin tailings

Abstract

The invention discloses a combined mineral separation and purification method for kaolin ore or kaolin tailings. The combined mineral separation and purification method comprises one or more of a kaolin separation process, a mica separation process, a feldspar separation process, a quartz sand separation process and a magnetic product separation process. Through physical size grading, mineral separation and sorting of optical color sorting, mineral separation and sorting of flotation, mineral separation and grading and sorting of ultrasonic acoustics and the like in the mineral separation technological process, the purposes that grading is accurate, separation is sufficient, sorting is easy, the quality and purity of produced products are high, the application field is wide, and the product quality of the application field is improved are achieved. By adopting the method, the blank of extracting a high-purity material from kaolin ore (or kaolin tailings) in China can be filled, and a high-purity raw material quality foundation is laid for further deep processing of a silicon material of a product. The value output level of domestic kaolin ore (or kaolin tailings) is greatly improved, a large amount of solid waste generated by mining and mineral separation of the kaolin ore is solved, and the method is green, environmentally friendly, cyclic and energy-saving.
