example 1

[0029] Example 1, such as figure 2 As shown, the equipment used in coal series kaolin decarburization process includes raw ore conveyor belt A, crusher B, grading screen C, three-product dense medium cyclone D, ball mill E, flotation machine F, coal product conveyor belt G, kaolin Product conveyor belt H. The working process is as follows:

[0030] The raw ore 1 transported from the raw ore conveyor belt A enters the crusher B for crushing operation, and the crushed product 2 that is fully dissociated from coal and kaolin is obtained;

[0031] The crushed product 2 enters the grading sieve C through the chute for grading operation, and the coarse product 3 on the sieve and the fine product 4 under the sieve are obtained;

[0032] The coarse-grained product 3 on the sieve enters the three-product dense-medium cyclone D for sorting operation, and obtains three products: the re-selected low-density product 5, the re-selected intermediate density product 6 and the re-selected h...

Abstract

The invention discloses a decarbonization process for coal series kaolin. The decarbonization process comprises crushing, grading, reselection, reselected medium-density product crushing or ore grinding, and flotation and specifically comprises the steps of crushing coal series kaolin raw ore, and grading crushed products; feeding coarse particle products obtained by grading into reselection equipment for sorting to obtain reselected low-, medium- and high-density products; mixing the reselected medium-density products subjected to crushing or ore grinding with fine particle products obtained by grading and feeding into flotation equipment for sorting to obtain flotated foam products and products in a flotation tank; recycling the reselected low-density products and the flotated foam products which are coal resources, and recycling the reselected high-density products and the products in the flotation tank which are kaolin. According to the process, organic carbon in the coal series kaolin can be efficiently removed, and kaolin products which are higher in purity and more applicable to further deep processing are obtained; furthermore, the decarbonization process can efficiently recycle and use the organic carbon, so that waste of the coal resources is avoided, and the environment is protected.

Description

technical field [0001] The invention relates to a kaolin decarburization process, which is especially suitable for the decarburization process of coal series kaolin belonging to non-metallic ore. Background technique [0002] my country's coal-measure kaolin has large reserves, good quality, and wide distribution. Almost large coal mines have associated or paragenetic kaolin. According to incomplete statistics, the proven reserves are 1.673 billion tons, accounting for about 10% of the world's proven reserves of kaolin. Coal series kaolin is a precious natural resource and an important non-metallic mineral with high utilization value. After mining and deep processing, due to its special physical and chemical process properties, such as fire resistance, electrical insulation, chemical stability, Dispersion, etc., can be widely used in papermaking, rubber, paint, chemical industry, building materials, metallurgy, ceramics, glass, electric porcelain, petroleum and other indust...
