Embodiment 1

[0014] Example 1: Take 70kg of Karin-type gold tailings and 30kg of shale, and pass them together on a pair of rollers with a spacing of 2mm, stir with two shafts, adjust the moisture content to 18-23%, age for 24 hours, and extrude to form a solid embryo body. After drying, place the green body in a tunnel kiln and sinter at 1050°C for 1 hour to obtain a Karin-type gold tailings sintered brick with a compressive strength of 35.8Mpa.

Embodiment 2

[0015] Example 2: Take 60kg of Karin-type gold tailings and 40kg of shale, put them together on the pair of rollers with a spacing of 2mm, stir with two shafts, adjust the moisture content to 18-23%, age for 48 hours, and extrude to a hollow rate of 35% The green body was dried naturally, and then the green body was placed in a wheel kiln and sintered at 1000°C for 1 hour to obtain a Karin-type gold tailings sintered brick with a compressive strength of 23.8Mpa.

Embodiment 3

[0016] Example 3: Take 70kg of Karin-type gold tailings and 30kg of coal gangue, and pass them together on a pair of rollers with a spacing of 2mm, stir with two shafts, adjust the moisture content to 18-23%, age for 36 hours, and extrude to form a solid embryo body. After drying in a tunnel kiln, the green body was sintered at 950°C for 1 hour to obtain a Karin-type gold tailings sintered brick with a compressive strength of 17.2Mpa.

Abstract

The invention discloses a Carlin-type gold mine tailing sintered wall material and a preparation method thereof. The wall material is prepared by sintering the following components, by weight: 10-90 parts of Carlin-type gold mine tailing, 90-10 parts of auxiliary materials, and 18-30 parts of water. The auxiliary materials are one or more than two selected from clay, shale and gangue. Compared toprior art, according to the invention, the sintered wall material is prepared by using a main material of Carlin-type gold mine tailing. The method is advantaged in high slag take, low production cost, good product property, and the like. The strength of the wall material satisfies requirements. The preparation method provided by the invention is compatible with that of traditional sintered bricks, and can be popularized in traditional sintered brick factories.

Description

technical field [0001] The invention relates to the technical field of wall materials, in particular to a Karin-type gold tailings sintered wall material and a preparation method thereof. Background technique [0002] my country is a populous country, which consumes a lot of building materials every year. The sintered wall material has the advantages of good durability, convenient material acquisition, simple process, and cheap price, making it a widely used building material. In the process of producing clay sintered wall materials, a large amount of clay resources are consumed and farmland is destroyed. Therefore, my country needs to use a large number of various waste residues to replace clay to produce sintered wall materials. [0003] Gold mine tailings is a kind of waste residue from the gold mining and dressing industry, and it is also the second largest metal tailings discharged in my country. In my country, the utilization rate of gold tailings is very low, an...
