Embodiment 1

[0023] Referring to Figure 1, the production process of gold mine tailings concrete colored tiles adopts a fully automatic cement tile filter press molding machine and its production line, which completely changes the shortcomings of roughness and poor compactness of tiles produced by traditional extrusion or rolling production lines. , the new process adopts the method of 120 tons of high-pressure molding, using gold tailings as aggregate, cement, sand and other plastic concrete as raw materials, using a special mold, after drainage and filtration, automatic demoulding, natural maintenance, automatic spraying And other processes to make it shape.

[0024] The raw materials for the production of cement tiles must use a wheel-type quantitative forced mixer, equipped with a mixer with a capacity of 350 liters, a motor power of 4KW, and a mixing time of 5-10 minutes to make the materials evenly mixed and the concrete to achieve good workability.

[0025] Raw material ratio:

[0...

Embodiment 2

[0047] The difference from Example 1 is that the ratio of raw materials for gold ore tailings concrete colored tiles is

[0048] Cement 40%, gold mine tailings 40%, yellow sand 20%, plasticizer rock sand crystal quality is one thousandth of the material gold mine tailings, cement, sand, fiber quality is the material gold mine tailings, cement, Five thousandths of the sand, the cement-bone ratio (cement: aggregate) is 1:1.5, and the water-cement ratio (water:material) is 1:0.25.

Embodiment 3

[0050] The difference from Example 1 is that the ratio of raw materials for gold ore tailings concrete colored tiles is

[0051] Cement 30%, gold mine tailings 55%, yellow sand 15%, plasticizer rock sand crystal quality is 6 / 1000 of materials gold mine tailings, cement, sand, fiber quality is materials gold mine tailings, cement, Ten thousandths of the sand, the cement-to-bone ratio (cement: aggregate) is 1:2.0, and the water-cement ratio (water:material) is 1:0.35.

Abstract

The invention discloses a gold ore tail sand concrete coloured tile and preparing craft in architectural materials production technique domain, which comprises the following steps: choosing gold ore tail sand, cement and sand as main material; allocating mass matching at 40%-55%, 30%-40%, 15%-25% separately; 1. stirring the raw material; extrusion forming; 2. curing; demoulding; half-finished product stowing; adding into water; curing; 3. drying; spraying; finishing product. This invention adopts high-pressure compression molding method, which possesses merits of dense tile body and polish surface.

Description

1. Technical field [0001] The invention relates to a gold mine tailings concrete colored tile and a production process, belonging to the technical field of building material production. 2. Background technology [0002] According to relevant reports, my country produces 600 million tons of mine tailings every year, with a cumulative inventory of more than 7 billion tons, which has become a major pollution source. At present, the comprehensive utilization rate of domestic tailings is less than 7%, and a large number of tailings have been piled up. seriously polluted the environment. In this regard, we can carry out comprehensive utilization in at least three ways, one is to recover useful components from the tailings, the other is to make full use of the tailings to make new building materials, and the third is to fill the goaf with the tailings. [0003] Concrete tiles produced by traditional extrusion or rolling production lines have shortcomings such as roughness and poor ...
