Description
One, technical field
The present invention relates to a kind of production method of extracting potassium sodium aluminium from grouan, particularly a kind of biotite moyite waste material that utilizes is by the special flow process of removal of impurities, purification and the production method of technology acquisition potassium sodium aluminium ceramic raw material.
Two, background technology
Potassium sodium aluminium is widely used in ceramic industry, is the main raw material that porcelain making is produced.Traditional preparation method overwhelming majority is by directly exploiting in the potassium felspar sand mineral deposit, and shortage of resources poorness, the raw ore iron content is too high, whiteness is low, this type of ore directly enters ceramics factory after the fragmentation after exploitation is come out, without the removal of impurities purification processes, quality is lower, majority does not meet the technical requirement of producer, has seriously influenced ceramic quality.
At present, the ceramic production line of various places, Wuzhou enlarges day by day, and there are Teng County, Cenxi City etc. in fairly large production base, estimates ton surplus the various ceramic raw materials 200,000 of daily requirement, and wherein potassium sodium aluminum feedstock is tens thousand of approximately tons, and consumption is very big.And Teng County, Cenxi almost do not have the potassium felspar sand mine, and ground such as required potassium albite leans on far away from the Hunan substantially, Sichuan, Xinyi, Guangdong, He Prefecture are supplied with, and the transportation cost costliness has increased product cost.
Three, summary of the invention
The biotite moyite contains useful matteies such as abundant potassium, sodium, aluminium.After purification, removal of impurities, can make the important source material of Production of Ceramics.
The purpose of this invention is to provide a kind of biotite moyite waste material that utilizes and concentrate the production method that obtains potassium sodium aluminium ceramic raw material through broken, system sand, removal of impurities, purification, the grouan waste disposal become be available advanced ceramic raw material, one is sharp environmental and ecological, two profits are made rational use of resources, three sharp energy-saving and emission-reduction meet the development trend of following Production of Ceramics raw material sources.
The production method of utilizing the grouan waste material to extract potassium sodium aluminium ceramic raw material of the present invention is characterized in that utilizing biotite moyite waste material to be raw material, concentrates through broken, system sand, removal of impurities and purification, obtains potassium sodium aluminium ceramic raw material stone flour, the steps include:
