Differential separation and upgrading method for feldspar minerals

Abstract

The invention provides a sorting method for differential feldspar ore separation and purification of feldspar minerals. According to the sorting method, raw feldspar ore is divided into two size fractions in a coarse grinding state according to the natural feature that the dissemination granularity of the feldspar minerals is uneven, the two size fractions are different in quality, the coarse fraction raw feldspar ore is low in iron content, the high-quality fine fraction raw feldspar ore is high in iron content, the fine fraction raw feldspar ore is sorted to obtain high-quality concentrates through a simple and practical method, slurry is removed from the low-quality coarse fraction raw feldspar ore, and the coarse fraction raw feldspar ore is sorted to obtain low-quality feldspar concentrates through a flotation method suitable for fine fraction purification. The sorting method for differential feldspar ore separation and purification of the feldspar minerals has the advantages that the process is simple, the product quality is good, the product value is high, the recovery rate is high, environmental pollution is low, and energy conservation and consumption reduction are realized, thereby being suitable for purification of feldspar ore with high ion content and coarse feldspar mineral dissemination granularity.

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.
