A kind of differential beneficiation and upgrading method of feldspar minerals

Abstract

The invention provides a sorting method for differential separation and purification of feldspar minerals, which is to divide the raw feldspar ore into two parts under coarse grinding according to the natural characteristics of feldspar mineral embedding and uneven particle size. Grade, there is a quality difference between the two grades, the iron content of the coarse grade is low, and the iron content of the fine grade is high, and the high-quality feldspar raw ore is selected by a simple and practical method Concentrate, after desliming the feldspar raw ore with relatively low quality and particle size, it is sorted by flotation method suitable for fine-grained impurity removal, and relatively low-quality feldspar concentrate is obtained. This invention makes full use of the characteristics of natural inhomogeneity of minerals. The invention has the characteristics of simple process, good product quality, high product value, high recovery rate, low environmental pollution, energy saving and consumption reduction, etc. It is suitable for high iron content, feldspar It is suitable for the purification of feldspar ore with slightly coarser mineral embedded particle size.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of resources, and relates to a method for differential beneficiation and quality improvement of feldspar minerals. Background technique [0002] Feldspar is a potassium-containing framework silicate mineral with a long melting interval and good chemical stability. It is widely used as a raw material for glass, ceramics, chemicals, abrasives, glass fibers, welding rods and other industries; Stone raw materials have accounted for more than 50% of the entire raw material formula of ceramic glazes, polished tiles, and sanitary porcelain. The quality of feldspar raw materials directly affects the quality grade of ceramic and glass products. The technical indicators for evaluating the quality of feldspar products are mainly Fe content and K 2 O, Na 2 O content. In the production of white glass, the iron in the raw material will have adverse effects on the light transmittance and color of the ...

Problems solved by technology

[0005] The above-mentioned traditional feldspar iron removal and upgrading process all emphasize the degree of dissociation between minerals, and process the feldspar ore itself without distinction, that is, it emphasizes that all ores are broken and ground to the same particle size for sorting Purification, while ignoring the natural inhomogeneities among the feldspar minerals themselves

A large number of studies have found that the quality of feldspar minerals with different particle sizes is quite different after grading in the state of coarse grinding, that is, the quality of feldspar has a difference in particle size.
