Embodiment 1

[0025] In the embodiment of the present invention, the method for producing ceramic products by using spent rock powder, comprises the following steps:

[0026] 1) Mix granite waste stone powder with water at a high speed, and then separate it with a 60-mesh vibrating screen, and directly enter the separated stone slurry below 60 mesh into the electromagnetic beneficiation process;

[0027] 2) Electromagnetic separation process: Use a separation machine with a magnetic field strength of 6000-15000 Gauss to conduct magnetic separation on the separated stone pulp with a concentration of about 30%. After 6000 high magnetic separation, the whiteness reaches about 53 degrees, and then after 15000 magnetic separation, the whiteness increases to 62 degrees, and the iron content is less than 0.2%. High white potassium albite powder containing 4.5% potassium, 4% sodium, 16% aluminum, 0.18% iron, 73.5% silicon, 0.033% titanium, 0.067% magnesium, and 1.5% calcium silicate;

Abstract

The invention discloses a method for producing ceramics through purified granite powder waste. 10-35 parts by weight of zircon sand, 5-30 parts by weight of high-whiteness potassium-sodium feldspar powder, 3-25 parts of kaolin, 5-25 parts of pyrophyllite, 3-25 parts of gypsum, 3-20 parts of nutshell powder, 2-20 parts of iron mine milltailings, 1-15 parts of zinc oxide, 1-15 parts of magnesium oxide, 1-15 parts of barium oxide, 1-10 parts of pentalyn, 1-10 parts of ammonium citrate and 1-10 parts of calcium hypophosphite are weighed; kaolin, pyrophyllite and gypsum are taken to be mixed and crushed, and wet ball milling, drying, calcining, water quenching, drying and crushing are carried out; zircon sand, high-whiteness potassium-sodium feldspar powder and iron mine milltailings are taken to be mixed and crushed, and size mixing, microwave treatment, size mixing, ultrasonic treatment and drying are carried out; the prepared powder and the remaining raw materials are stirred, mixed, subjected to compression moulding and sintered, and the ceramics are obtained. The ceramics have the very prominent mechanical property, the production cost is reduced, the service life is prolonged, and the method is widely applied to producing whiteware, domestic ceramics and craft ceramics.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a method for producing ceramic products by utilizing waste rock powder. Background technique [0002] my country's production of daily-use ceramics accounts for more than 60% of the world, and that of building ceramics accounts for 50% of the world. According to the current output and production level of ceramics (including building and sanitary ceramics), the national ceramic industry consumes more than 100 million tons of mineral raw materials every year. After long-term mining and consumption, the ceramic raw material resources in various domestic ceramic production areas are becoming increasingly exhausted. The original China Jingdezhen, the capital of porcelain, was listed by the State Council as a resource-exhausted city in 2009. The increasingly tense supply of high-quality raw materials is a common problem faced by all ceramic production areas. Huayan is a wid...
