Problems solved by technology

[0002] At present, only a small number of copper tailings have the economic value of re-selection in my country, and more copper tailings do not have the economic value of re-selection, and the area of ​​the same tailings without re-selection economic value is increasing day by day, which increases the cost of the enterprise. The economic burden has caused a waste of land and resources, especially the existence of copper tailings heap leaching waste, which is the source of wind and sand during drought and harmful leachate during rain, and the surrounding vegetation is exhausted or even extinct, which brings environmental damage Great harm

preparation example Construction

[0084] According to a third aspect of the present invention, the present invention provides a method for preparing the above-mentioned vegetation composite substrate, comprising the steps of:

[0085] Portland cement, copper tailings heap leaching waste residue, lime, zeolite powder, peat soil, optional polyvinyl alcohol, optional hydrogen peroxide and water are evenly mixed, then poured into a mold to form, molded, and dried to obtain Vegetated composite substrates.

[0086] The preparation method of the vegetation composite base material provided by the invention has the advantages of simple process, convenient operation, easy realization of industrialized large-scale production, and further reduction of preparation cost.

[0087] In a preferred embodiment of the present invention, in terms of parts by mass, in the process of preparing the vegetation composite substrate, the amount of water added is 20-25 parts, preferably 22-24 parts.

[0088] In the process of preparing t...

Embodiment 1

[0120] like figure 1 As shown, the present embodiment provides a vegetation composite substrate 100, the vegetation composite substrate 100 is formed with a plurality of continuously superimposed holes, the holes include large holes 101 and small holes 102, and the small holes 102 are arranged in the large holes 101 In the center and / or around the center, the large hole 101 and the small hole 102 communicate with each other to form internal pipelines for plant growth to store water, repel water, and keep water.

[0121] In this embodiment, the small hole 102 is arranged in the center and / or around the large hole 101, which means that the small hole 102 can be arranged in the center of the large hole 101, or can be arranged around the large hole 101, and can also include multiple Some of the small holes 102 are set in the center of the big hole 101 , and some of the small holes 102 are set around the big hole 101 .

[0122] In this embodiment, the vegetation composite substrat...

Embodiment 2

[0128] This embodiment provides a vegetation composite base material, its structure is as embodiment 1, and the vegetation composite base material provided by this embodiment includes the following raw materials in parts by mass: 35 parts of 42.5 ordinary Portland cement, copper tailings 50 parts of heap leaching waste residue, 5 parts of free lime, 5 parts of zeolite powder, 3 parts of peat soil, 0.5 part of polyvinyl alcohol, wherein the particle size of copper tailings heap leaching waste residue is 200 mesh, and the particle size of free lime is 200 mesh, The particle size of zeolite ash is 200 mesh.

Abstract

The invention provides an application of copper tailings heap leaching waste slag, a vegetation composite substrate and a preparation method, and relates to the technical field of comprehensive utilization of waste slag. The application of the copper tailings heap leaching waste slag in the preparation of composite materials for environmental restoration, the invention provides The vegetation composite substrate includes the following components in parts by mass: Portland cement 30-40 parts, copper tailings heap leaching waste 40-50 parts, lime 5-10 parts, zeolite powder 2-5 parts, peat 1-5 parts of soil, the vegetation composite substrate provided by the present invention, through the cooperation of Portland cement, copper tailings heap leaching waste residue, lime, zeolite powder and peat soil, not only has excellent mechanical properties, but also has good weather resistance And ammonia nitrogen removal performance, but also reduces the preparation cost of preparing composite substrates, realizes the copper tailings heap leaching waste into treasure, and is more conducive to the coordinated development of the environment and economy.

Description

technical field [0001] The invention relates to the technical field of waste slag comprehensive utilization, in particular to an application of copper tailings heap leaching waste slag, a vegetation composite base material and a preparation method. Background technique [0002] At present, only a small number of copper tailings have the economic value of re-selection in my country, and more copper tailings do not have the economic value of re-selection, and the area of ​​the same tailings without re-selection economic value is increasing day by day, which increases the cost of enterprises. The economic burden has caused a waste of land and resources, especially the existence of copper tailings heap leaching waste, which is the source of wind and sand during drought and harmful leachate during rain, and the surrounding vegetation is exhausted or even extinct, which brings environmental damage. Great harm. [0003] Therefore, how to reduce the stock of copper tailings heap leac...
