Problems solved by technology
For a long time, the comprehensive utilization of mine tailings has been a worldwide problem. Although a lot of research has been done on the comprehensive utilization of mine tailings at home and abroad, due to various technical and economic reasons, most of them have not been put into industrial realization.
[0003] In summary, it has been reported that mine tailings are used as auxiliary raw materials to produce cement, wall bricks, and road materials, but construction waste is used as the main raw material for the production of aerated blocks.

Embodiment Construction
[0014] A method for producing ore tailing insulation bricks. The raw materials are calculated in parts by weight: 70 parts of mine tailings, 12 parts of phosphogypsum, 6 parts of aluminum powder, 25 parts of fly ash, 55 parts of albite particles, Portland cement 35 parts, 5 parts of plant ash, 3 parts of foam stabilizer, 3 parts of styrene-acrylic emulsion, 110 parts of water;
[0015] Its concrete preparation method is as follows:
[0016] (1) Use a jaw crusher to crush mine tailings and albite into a size of 2mm to 3mm, heat it to 600-700°C in a resistance furnace, and keep it warm for 2-3 hours; after cooling, use a ball mill to grind 1.5-2 Hours, finally mixed with phosphogypsum, aluminum powder, fly ash, foam stabilizer, 30-40% water, mixed for foaming treatment;
[0017] (2) Mix the foamed mixture with Portland cement, plant ash, styrene-acrylic emulsion and the remaining water and stir evenly, put the mixture into the mold to make a green body, and the green body is in...

The invention discloses a method for preparing an ore tailing thermal-insulation brick. The ore tailing thermal-insulation brick comprises, by weight, 70 parts of ore tailings, 12 parts of phosphogypsum, 6 parts of aluminum powder, 25 parts of fly ash, 55 parts of albite particles, 35 parts of portland cement, 5 parts of plant ash, 3 parts of a foam stabilization agent, 3 parts of a styrene-acrylic emulsion and 110 parts of water. The method obviously relieves environment pollution and safety problems caused by ore tailing stockpiling, increases types of used waste materials, changes a waste ratio, has a low production cost and realizes full utilization of wastes in the premise of environmental protection.
Description
technical field [0001] The invention relates to the field of new building materials, and in particular belongs to a method for making ore tailing slag insulation bricks. Background technique [0002] Mine tailings are one of the products of sorting operations in mineral processing, and the content of useful components is the lowest among the products of this operation. Under the current technical and economic conditions, mines that are not suitable for further separation are called final tailings. For a long time, the comprehensive utilization of mine tailings has been a worldwide problem. Although a lot of research has been done on the comprehensive utilization of mine tailings at home and abroad, most of them have not been implemented in industry due to various technical and economic reasons. [0003] In summary, there have been reports on using mine tailings as auxiliary raw materials to produce cement, wall bricks, and road materials, but there have been no reports on u...
