Deep processing process of high-purity ultra-white potassium feldspar material

Abstract

The invention relates to a deep processing process of a high-purity ultra-white potassium feldspar material. The deep processing process is implemented through the following key steps: mineral resources are selected and configured; in the state after coarse crushing and before sand making, screening is performed without washing, so as to reduce the loss of fine powder materials; as for rinsing after sand making, if the mica content is high, classified rinsing by water power is performed only once after fine crushing and sand making, so as to float and separate mica and other lightweight substances, and enough upwelling water flow can allow the mica and the other lightweight substances to drift away; a method of secondary classified falling-back and precipitation is used to subject most offine powders to classified falling down and recovery, so as to maximally ensure no or minimum loss of the powder materials and thus to ensure less losses of substances including silicon, aluminum, potassium, sodium and calcium which can indicate whiteness; repeated trials are performed to accurately set a ratio of water to powder of a slurry; and between two times of magnetic separation, ultrasonic waves are used for separating weakly-magnetic substances by vibration before electrical separation. The deep processing process has the advantages as follows: a high-grade high-purity ultra-white product material can be produced, the whole process adopts a full-physical processing method, and zero emission, no pollution and environmental friendliness are achieved.

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...
