Preparation technique of copper tail mud produced aerated brick

Abstract

The invention discloses a preparation technique of a copper tail mud produced aerated brick, which includes steps of S1, treatment of copper tail mud; S2, puling of coal ash; S3, coarse processing oflime and gypsum; S4, raw material mixing; S5, raw material pulping; S6, brick blank production; S7, brick blank cutting; S8, carbonization; S9, autoclaved curing. Compared with a conventional aeratedbrick production technique, the copper tail mud is added in the aerated brick; through carbonization and steaming maintenance, the pressure strength of brick can be increased, land waste is reduced, production cost is saved, and factory benefit is improved.

Description

technical field [0001] The invention belongs to the field of aerated brick manufacturing, and more specifically relates to a preparation process for producing aerated bricks from copper tailings. Background technique [0002] With the continuous development of social economy, the demand for energy and resources continues to increase, and the amount of mining of mineral resources is also increasing day by day, while the discharge of tailings is also increasing sharply. Since many types of mineral resources in our country are faced with the problem of less rich ore and more lean ore, the output of tailings is even more impressive. Copper ore is a major mineral in my country. A large amount of copper ore is mined and smelted every year, and a large amount of copper tailings are also discharged. The disposal of copper tailings has always been a difficult problem. Whether it is to cover soil for land reclamation or to shelve on the spot will cause environmental pollution. The ...

Whether it is to cover soil for land reclamation or put it aside on the spot, it will cause environmental pollution

The aerated bricks need to take soil during production, resulting in a reduction in land area
