Problems solved by technology

[0003] The application of monazite in China is mainly to use monazite as raw material for rare earth smelting and separation, and the main problem of monazite smelting is: a large amount of tailings produced by smelting and separation are accumulated, which is difficult to recycle, causing damage to the environment. extreme pressure
In addition, monazite has a certain radioactivity, which greatly limits its application in other fields.

Embodiment 1

[0039] The method for utilizing monazite to produce negative oxygen ion powder comprises the steps:

[0040]Step 1. Preparation and pretreatment of monazite: add water to the monazite and grind it with a ball mill until the D98 in the particle size distribution of the material is less than 4 μm. The mass ratio of the material to water during grinding is 1:0.5, and then add a dispersant for dispersion. The added dispersant The mass ratio of monazite and monazite is 1:0.008 to obtain monazite dispersion, add surfactant in monazite dispersion, stir and disperse to obtain modified monazite dispersion slurry; wherein the monazite dispersion and surfactant The mass ratio is 1:0.008; the surfactant is a mixture of stearic acid and silicone oil in a mass ratio of 2 to 3:1;

Abstract

The invention relates to a method for producing negative oxygen ion powder by using monazite and application of the negative oxygen ion powder, and belongs to the technical field of monazite processing. By modification treatment of monazite material, tourmalinite and barium salt, the negative oxygen ion powder is obtained by modification coating. The application fields of monazite are broadened. The raw materials used in the invention include monazite, tourmalinite and common natural barium salt undergo pretreatment and coating compounding to form the product. The production process is simpleto operate, and can be promoted in the field. The environmental problem of tailing stacking due to monazite refinement can be alleviated, and high economic value can be created.

Description

technical field [0001] The invention belongs to the technical field of monazite processing, and in particular relates to a method for producing negative oxygen ion powder by using monazite and an application of the negative oxygen ion powder. Background technique [0002] Monazite is one of the main rare earth metal mines. India, Australia, South Africa and other countries are all important producing areas of monazite. Its chemical composition is mainly light rare earth, and the content of rare earth oxide is about 65%. It also contains thorium oxide and Uranium oxide is therefore often radioactive. Its crystal form belongs to monoclinic monoclinic columnar crystal. At present, the sources of monazite ore used in China mainly include: imported placer and tailings produced by domestic mineral processing enterprises. [0003] The application of monazite in China is mainly to use monazite as raw material for rare earth smelting and separation, and the main problem of monazite...
