Problems solved by technology

It can increase the viscosity and chemical stability of enamel, and can also be used to make enamel raw materials, and can also be used as insulating electrical porcelain materials, but potassium feldspar minerals are often accompanied by some dark minerals and some pigment ions are adsorbed on the surface of potassium feldspar particles, affecting the original ore and The whiteness of the product reduces the quality of the product and limits the application range of the product, which becomes the main obstacle for the potassium feldspar processing industry to adjust the product structure and expand the market

Embodiment 1

[0024] A kind of production method of potassium feldspar, specifically comprises the following steps:

[0025] S1. Desliming: Excavate the low-grade potassium feldspar raw ore, and transfer the raw ore to the cleaning machine through the screw conveyor with a pitch ratio of 3:1 between the pitch of the helical blade in the first half and the helical blade in the second half, and then put it on the cleaning machine There is a spiral cleaning pipeline, and high-pressure nozzles are evenly arranged around the cleaning pipeline. The outlet of the high-pressure nozzle faces the inside of the cleaning pipeline. The water inlet of the high-pressure nozzle is connected to the water pipe, and the water pipe is connected to the high-pressure pump. Turn on the high-pressure pump, and water is sprayed from the high-pressure nozzle to wash the raw ore in the cleaning pipeline to remove the sludge on the surface of the raw ore;

[0026] S2. Ball milling: dehydrating the raw ore treated in s...

Abstract

The invention belongs to the technical field of mineral dressing and particularly discloses a potassium feldspar production method, comprising the specific steps of S1, removing mud; S2, ball milling;S3, magnetically removing impurities; S4, drying, to be specific, adding concentrate pulp into a drying furnace, and drying to obtain solid concentrate; S5, calcining, to be specific, transferring the solid concentrate to a calcining furnace for calcining at 1300-1500 DEG C, and adding a mixed gas of nitrogen and argon in a volume ratio of 1:2 to fill the calcining furnace during calcining; S6, removing impurities, to be specific, subjecting the calcined mineral to ball milling to the particle size of 0.5 cm so as to obtain pulp; S7, carrying out floatation, to be specific, adding sulfuric acid solution, adjusting pH of the pulp to 6.2-6.8, adding a collecting agent and a foaming agent, and collecting finished foam to obtain concentrate pulp II; S8, removing oil. The method herein helps extract main effective ingredients of potassium feldspar and also helps effectively remove the impurities that affect the color of potassium feldspar powder.

Description

【Technical field】 [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a production method of potassium feldspar. 【Background technique】 [0002] Potassium feldspar is a natural mineral containing K2O, Al2O3, SiO2 and impurities such as Fe2O3, and its molecular formula is K2O·Al2O3·6SiO2. Potassium feldspar is the main raw material for porcelain glaze in the ceramic industry; it is a kind of glass mixture. It can increase the viscosity and chemical stability of enamel, and can also be used to make enamel raw materials, and can also be used as insulating electrical porcelain materials, but potassium feldspar minerals are often accompanied by some dark minerals and some pigment ions are adsorbed on the surface of potassium feldspar particles, affecting the original ore and The whiteness of the product reduces the quality of the product, limits the application range of the product, and becomes the main obstacle for the potassi...
