Problems solved by technology

However, there are almost no potassium feldspar mines in Teng County and Cenxi, and the required potassium and albite feldspar are basically supplied in Hunan, Sichuan, Guangdong Xinyi, Hezhou and other places, and the transportation cost is expensive, which increases the product cost.

Embodiment Construction

[0018] 1. Material selection: choose biotite potassium long granite stone, no matter the meat red, orange red, pink of medium flower, fine flower and large flower, waste stone with biotite, try to avoid epidermis weathering stone and large Black gallstones, after being cleaned and removed, are reserved for use, and are required to be cleaned before entering the factory to prevent impurities such as burrs from entering the workshop;

[0019] 2. Crushing: divided into two stages of crushing. The first coarse crushing is to crush the raw material stone. After the first crushing, the medium stone with a diameter of 20-60mm is obtained; the second crushing is to crush the medium stone obtained from the first crushing. After the second crushing, small stones with a diameter of 10-15mm are obtained; in the secondary crushing, they must pass through a vibrating screen, and those smaller than 4mm are directly sent to the primary magnetic separation to remove iron and impurities;

Abstract

Invented a production method of using granite waste to extract potassium-nadium-aluminum ceramic raw materials, using biotite potassium feldspar granite waste as raw material, through crushing, sand making, fine grinding, impurity removal, purification and concentration, etc., to obtain potassium-sodium-aluminum ceramic raw material stone powder . The method can obtain high-quality ceramic raw materials containing 5-10% of potassium, 3.5-4.5% of sodium, 5-17% of aluminum, 60-74% of silicon, 0.2% of iron, 0.6% of calcium and 38-61% of whiteness. The present invention utilizes granite waste to produce potassium-sodium-aluminum ceramic raw materials, turns waste into treasure, solves the problems of serious environmental pollution and waste of resources due to the discharge of a large amount of granite waste, and at the same time ensures the sustainable development of the stone industry and makes the waste of the stone industry Transformation of matter into energy for new ceramic production.

Description

1. Technical field [0001] The invention relates to a production method for extracting potassium, sodium and aluminum from granite, in particular to a production method for obtaining potassium, sodium and aluminum ceramic raw materials by using biotite potassium feldspar granite waste through a special flow and process of impurity removal and purification. 2. Background technology [0002] Potassium sodium aluminum is widely used in the ceramic industry and is the main raw material for porcelain production. Most of the traditional obtaining methods rely on direct mining in potassium feldspar deposits, and the resources are scarce and poor. The iron content of the raw ore is too high and the whiteness is low. After mining, this kind of ore is directly crushed and then enters the ceramic factory without impurity removal. Purification treatment, the quality is low, and most of them do not meet the manufacturer's technical index requirements, which seriously affects the quality o...
