Method for preparing stone-like floor tiles from bauxite waste ore dressing tailings

Abstract

The invention belongs to the technical field of stone-like floor tiles, and particularly relates to a method for preparing stone-like floor tiles from bauxite waste ore dressing tailings. A plate brick mold comprises a base; a lower mold bin is fixedly connected into a cavity of the base; sliding grooves are evenly formed in the inner wall of the lower mold bin, and sliding blocks are connected into the sliding grooves in a sliding mode; lower mold plates are evenly arranged in the lower mold bin; an interlayer is fixedly connected between every two lower mold plates; and the lower mold platescorrespond to each other and form a lower mold cavity. The method is mainly used for solving the problems that most of existing molds for manufacturing floor tiles are used for compacting raw materials in the molds, but the floor tiles manufactured by the mode are in a solid state, so that the material consumption of the floor tiles is increased to cause waste, and meanwhile, when bubbles exist in the raw materials or compaction among the raw materials is insufficient in the injection molding process of the raw materials, cavities exist in the manufactured floor tiles, so that the service life of the floor tiles is shortened.

Description

technical field [0001] The invention belongs to the technical field of imitation stone floor tiles, in particular to a method for preparing imitation stone floor tiles by using bauxite waste ore dressing tailings. Background technique [0002] With the industrialized production of the "new technology for producing alumina by beneficiation Bayer method", the production cost of alumina has been effectively reduced, showing more and more significant technical advantages. However, due to the production of alumina by the Bayer method of ore dressing, the dressing tailings accounting for about 20% of the weight of the raw ore should be produced during the dressing process, and a processing plant with an annual processing capacity of 1.8 million tons of raw ore should produce nearly 400,000 tons of tailings on a dry basis. The stockpiling of these tailings brings a series of problems such as environmental impact and land occupation. Bauxite beneficiation tailings is a kind of soli...

AI Technical Summary

Problems solved by technology

The product performance is excellent, and the production process is simple, but the floor tiles are made of too much material, resulting in waste, and at the same time, the degree of compaction of raw materials and the content of gas cannot be guaranteed.
