A kind of high-purity ultra-white potassium feldspar material deep processing technology

Abstract

The invention relates to a high-purity ultra-white potassium feldspar material deep processing technology, which is implemented through the following key steps: selecting and configuring mineral resources; only screening without water washing in the stage from coarse crushing to sand blasting, so as to reduce the loss of fine powder; For rinsing after sand blasting, if there is a lot of mica content, the only hydraulic grading rinsing for fine sand blasting is to float and separate light substances such as mica, so that there is enough upwelling water to float away mica and light substances; take secondary grading and settling The method is to recycle most of the fine powder by classification, to keep the powder material to the maximum extent without loss or to minimize the loss, and to keep the material showing the whiteness index of silicon, aluminum, potassium, sodium and calcium with little loss. Repeated trials, precise configuration of water-powder-slurry ratio; between magnetic separation, ultrasonic waves before electric separation vibrate and separate weak magnetic materials. The invention has the advantages of being able to produce high-grade, high-purity ultra-white product materials, and at the same time adopting a full physical treatment method in the whole process, with zero discharge, no pollution, and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of deep processing of potassium feldspar, and in particular relates to a deep processing technology of high-purity ultra-white potassium feldspar material. Background technique [0002] Potassium feldspar is an aluminosilicate mineral of potassium, sodium, calcium and other alkali metals or alkaline earth metals, also called feldspar minerals. Potassium feldspar (K2O-Al2O3-6SIO2) is usually called orthoclase, belongs to the monoclinic crystal system, and is usually flesh red, white or gray. Potassium feldspar series are mainly orthoclase, microcline, sanidine, etc., aluminosilicate minerals. [0003] Potassium feldspar materials are mainly used for ceramic glaze materials and body materials, accounting for about 30%; basic materials for glass manufacturing account for about 45-50%, high-quality potassium feldspar materials are used in high-end ceramics, electronic ceramics, electronics There is a wide rang...
