Abstract
The invention discloses a method for preparing a ceramic material by virtue of copper tailings, and belongs to the fields of industrial solid waste resource comprehensive utilization and environmental protection. The method comprises the following steps of ball-milling and mixing 35 to 55 parts by weight of copper tailings, 25 to 40 parts by weight of steel slag, 10 to 25 parts by weight of clay, 0 to 15 parts by weight of feldspar, 0 to 10 parts by weight of talc and the like, and executing the procedures of sieving, drying, pressing or extrusion molding, sintering and the like to obtain the ceramic material, wherein the firing temperature is 1,080 to 1,160 DEG C. According to the method, the ceramic material is synergistically prepared from the copper tailings and the steel slag, and the ratio of the using amount of industrial solid waste to the total weight of the raw materials in the ceramic material reaches 65 to 85 percent, so that the industrial solid waste can be resourcefully utilized in large scale, and obvious social benefits and environmental benefits can be achieved; the copper tailings and the steel slag are small in granularity, so that ball-milling energy consumption in a ceramic material production process can be reduced; the sintering temperature is lower, so that the sintering energy consumption of the ceramic material can be reduced, and economic benefits are achieved; the method is relatively simple in process and easy to popularize and use.
Description
Technical field:
The present invention relates to a kind of method utilizing copper tailing to prepare stupalith, belong to Industrial Solid Waste comprehensive utilization of resources and field of environment protection.
Background technology:
In China industry ore dressing and smelting process, the generation of solid waste constantly increases, but the level of comprehensive utilization of current China's industrial tailings and metallurgical slag is not high, causes the burden of China's mine tailing and metallurgical slag huge.Although mine and smelting enterprise constantly strengthen technological development, the effective way exploring extensive resource utilization Appropriate application Industrial Solid Waste is still current vital task.
Industrial Solid Waste is utilized to be the important channel that mass-producing utilizes Industrial Solid Waste as ceramic industry raw material.Copper tailing Shi Tong manufacturing enterprise chooses through the technique such as flotation or leaching the solid waste discharged after copper resource, containing a large amount of silicate mineralss, can be used as the main raw material preparing stupalith.At present, " secondary " mine tailing that copper tailing produces after selecting again is still main utilizes copper tailing to prepare stupalith to store up mode process, both can alleviate the burden of copper manufacturing enterprise process mine tailing, can expand again ceramic raw material source.Patent publication No. CN102924113A, CN103030341A and patent announcement CN100591635C, CN102674883B propose the method utilizing copper tailing to prepare porous ceramics or glass material, these methods are all for utilizing copper tailing to prepare porous material, technique all has feasibility, but preparation process all employs pore former, make the control difficulty in production process comparatively large, be therefore unfavorable for that technology popularization is applied.Not yet having at present utilizes copper tailing to work in coordination with the report of prepared from steel slag for stupalith.
Summary of the invention:
The object of this invention is to provide a kind of copper tailing that utilizes and work in coordination with the method for prepared from steel slag for stupalith, realize the comprehensive utilization of resources of copper tailing and slag, the method has obvious society, economy and environment benefit.
Concrete technical scheme of the present invention, comprise the following steps: take raw copper mine tailing, slag, clay, feldspar, talcum, each raw materials by weight portion consists of: copper tailing 35 ~ 55 parts, 25 ~ 40 parts, slag, clay 10 ~ 25 parts, feldspar 0 ~ 15 part, 0 ~ 10 part, talcum.Then in compound, add tamanori 0.01% ~ 0.1%, dispersion agent 0.05% ~ 0.3%, being added water by compound is milled to 250 mesh sieves and tails over and be less than 0.8%.After slurry drying, by compression moulding or extrusion molding.Finally the base substrate after shaping is sent in kiln and fire at 1080 DEG C ~ 1160 DEG C, the stupalith that to obtain with copper tailing, slag be main raw material.
The present invention has the following advantages:
(1) utilize copper tailing to work in coordination with prepared from steel slag for stupalith, in ceramic raw material, Industrial Solid Waste consumption accounts for gross weight ratio up to 65% ~ 85%, can realize the extensive recycling of Industrial Solid Waste, have obvious social benefit, environmental benefit.
(2) copper tailing used and slag raw material particle size are comparatively thin, can reduce stupalith production process ball milling energy consumption, and firing temperature are lower, can reduce stupalith and burn till energy consumption, have certain economic benefit.
