Embodiment Construction

[0028] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0029] see figure 1 , the invention provides a method for making a red mud ceramic product, comprising the steps of:

[0030] Step 1, providing wet red mud lumps, mixing the wet red mud lumps with water and then dispersing to form dispersed raw red mud slurry;

[0031] Specifically, in the wet red mud lump, the particle size of the red mud powder is below 200 nanometers; the weight ratio of the wet red mud lump to water is 1:1˜0.5:1.

[0032] Specifically, in the step 1, ball milling is used to disperse the mixed wet red mud lumps and water to obtain raw red mud slurry.

[0033] Specifically, the pH value of the raw red mud slurry is 9-12.

[0034] Step 2, adjusting the pH value of the original red mud slurry to form a modulated red mud slu...

Abstract

The invention provides a manufacturing method of a red mud ceramic product, which comprises the following steps: carrying out a series of treatment on wet red mud blocks to obtain the red mud ceramicproduct. The problem that the red mud generated in the aluminum ore production process occupies space for storage is solved, and waste of manpower and material resources is avoided; the red mud whichis originally used as a waste material is used as a raw material for producing the red mud ceramic product, so that the utilization of the waste material is realized, the production cost is saved to agreat extent, the environmental pollution caused by the storage of the red mud can be avoided, and the requirements of green and sustainable development are met.

Description

technical field [0001] The invention relates to ceramic products, in particular to a method for making red mud ceramic products. Background technique [0002] The industrial solid waste produced in the production process of aluminum ore is called red mud because it contains a large amount of iron oxide and its appearance is similar to red soil. Because of its small particle size, usually below 200 nanometers, and its cohesiveness is extremely poor , the prior art cannot reuse this red mud, so it has to be stored as waste. And in order to prevent it from floating into the air and causing air pollution, it needs to be watered to keep a certain humidity so that it is stored in a wet mud block mode. Therefore, the red mud produced in the production process of bauxite has the problem of occupying storage space and consuming manpower and material resources; and with the increasing stockpiling of red mud, the pollution to the environment is becoming more and more serious. The uti...
