Embodiment 1

[0027] A method for producing quartz sand for ceramic glazes by utilizing quartz tailings, comprising the following steps:

[0028] (1) Washing: Put the quartz tailings with a particle size of 100-300 mesh into a hydrocyclone for cleaning until there is no obvious dirt on the surface;

[0029] (2) magnetic separation for the first time: put the cleaned quartz tailings obtained in step (1) into a magnetic separator to remove magnetic metal impurities in the material;

[0030] (3) Classification for the first time: separate out 100-200 mesh and 200-300 mesh quartz tailings from the quartz tailings obtained in step (2) and dehydrate for subsequent use;

[0031] (4) acid leaching: the quartz sand tailings raw material obtained in the step (3) is put into the sand washing cylinder respectively, and the inorganic acid is uniformly spread therein simultaneously, and after adding water, the concentration of the solid-to-liquid ratio is 40%, adding industrial hydrochloric acid, Indust...

Embodiment 2

[0037] A method for producing quartz sand for ceramic glazes by utilizing quartz tailings, comprising the following steps:

[0038] (1) Washing: Put the quartz tailings with a particle size of 100-300 mesh into a hydrocyclone for cleaning until there is no obvious dirt on the surface;

[0039] (2) magnetic separation for the first time: put the cleaned quartz tailings obtained in step (1) into a magnetic separator to remove magnetic metal impurities in the material;

[0040] (3) Classification for the first time: from the quartz tailings that step (2) obtains, screen out 100-200 purpose quartz tailings and then dehydrate for subsequent use;

[0041] (4) Acid leaching: Put the raw material of quartz sand tailings into the sand washing cylinder, and at the same time spread inorganic acid evenly in it, add water to make the concentration of solid-liquid ratio at 50%, add industrial hydrochloric acid, industrial sulfuric acid and industrial nitric acid, three The ratio of acid le...

Abstract

The invention discloses a method for producing quartz sand for ceramic glaze by using quartz tailing, relates to the technical field of quartz sand production. Through the steps of washing, performing primary magnetic separation, performing primary grading, performing acid pickling, performing secondary magnetic separation, performing secondary grading, drying and bagging, the quartz sand for the ceramic glaze, which can ensure good product performance, a unique decorative effect, less impurities, high purity, and avoidance from lead, cadmium and other harmful substances in the glaze, is obtained. By the method, the problems that in the conventional quartz sand producing process, pollution is caused by waste disposal of the tailing, and a product prepared by the conventional quartz tailing disposing method is not high in quality and has a limited application range are solved.

Description

technical field [0001] The invention relates to the technical field of quartz sand production, in particular to a method for producing quartz sand for ceramic glazes by utilizing quartz sand tailings. Background technique [0002] Quartz tailings are precious mineral resources, and the annual discharge in my country is tens of millions of tons, so resource utilization has become an inevitable trend. The annual discharge of quartz tailings and mine tailings in the country is more than 10 million tons. Discharging such a large amount of quartz tailings and mine tailings will directly cause serious environmental pollution, occupation of cultivated land, silting of rivers and reservoirs and other adverse consequences. Many enterprises are still relatively backward in technology and dust prevention, especially during the dry processing of quartz sand, a large amount of dust is generated, and the production environment is quite harsh, which seriously endangers the health of employ...
