Abstract

A disclosed zirconite tailing and coal gangue ceramic grinding ball is prepared from the following components in percentage by mass: 40-80 percent of zirconite tailings, 5-30 percent of coal gangue, 5-20 percent of aluminum oxide, 2-10 percent of feldspar, 1-5 percent of dolomite, 1-5 percent of talc, 1-5 percent of calcite, 1-5 percent of barium carbonate and 1-10 percent of quartz. The inventionfurther discloses a preparation method of the zirconite tailing and coal gangue ceramic grinding ball. The ceramic grinding ball prepared by taking the zirconite tailings and the coal gangue as mainraw materials is suitable for the related fields of mine metal mineral grinding, white mineral grinding, petroleum fracturing propping agents and the like, solid waste resource utilization is realized, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of ceramic grinding balls, in particular to a zircon tailings and coal gangue ceramic grinding ball and a preparation method thereof. Background technique [0002] The main producing countries of zircon in the world are Australia, the United States, Brazil, etc. my country's zirconium resource reserves rank fifth in the world, about 500,000 tons, accounting for only 1% of the world. The main producing areas are Guangdong, Hainan, Guangxi and other provinces, of which 94% of the production comes from seaside placer mines in Hainan. There are not many sources of zircon in my country, and Hainan sand has also been scarce in recent years. Therefore, the tailings produced by enriching zircon are also increasing year by year, the mining cost is getting higher and higher, and the tailing waste is also increasing. Environmental pressure is increasing. [0003] Coal gangue is the solid waste discharged during the process of co...
