Description
Technical field
The invention belongs to field of constructional engineering material, more particularly to a kind of method of CHARACTERISTICS OF TAILINGS SAND brickmaking.
Background technology
Mine tailing is the solid or powdered scrap that can not be utilized discharged after exploitation, sorting ore and temporary transient, including
Mill tailings and plant tailing, wherein mill tailings include the poor value that the association country rock that oneself produces is rejected with midway；
Plant tailing includes using certain technique, the mineral waste (mine tailing) discharged after mechanical washing ore, these tail pipe used in mine
It is delivered to Tailings Dam storage.
Mine tailing not only occupies cultivated land, and causes environmental pollution, and such as designing improper tailing dam and caving in can also cause personnel to hinder
Die, while Tailings transportation discharge needs a large amount of plant equipment and electric power facility.At present, due to earth resource shortage, countries in the world
All mine tailing is treated as secondary resource, field of comprehensive utilization is wide.In addition to useful component is extracted from mine tailing, also mine tailing is used
Make the casting resin of mine, be used to improve soil or be directly used in traffic, civil engineering in agricultural, while be also used for building materials neck
Domain, various construction materials etc. are produced as raw material.
At present, the comprehensive utilization ratio of China's mine tailing waste residue is only 7% or so, either using scale, makes value and economy
Benefit is all not fully exerted far away.A considerable amount of mine tailing waste residues do not find new purposes, can only for a long time stack, tie up agriculture
Field, destroy ecology, pollution environment, the serious sustainable development that govern mining industry.Research shows that mine tailing is kind of a complex mineral raw material,
For mine tailing in addition to containing a small amount of metal component, it is gangue mineral that it, which wants mineral composition, such as quartz, pyroxene, feldspar, garnet, hornblend
And its alteration ore deposit, clay, mica group aluminium silicate mineral, and the calcium carbonate and magnesium carbonate mineral such as calcite, dolomite；It studies part
Mainly based on the oxides such as silicon, aluminium, calcium, magnesium, iron, and with a small amount of sulphur, phosphorus etc.；It spends raw materials used very with building materials field
It is close, it is a kind of natural mixing material for having been processed into particulate.
The prior art development level and trend handled according to mine tailing waste residue resource, with reference to resource of tailings feature and future
Environmentally friendly demand for development, the very big all kinds construction material of research and development wide market, Tailings utilization amount, is to make mine tail
Ore deposit solves puzzlement, realizes an effective way of recycling.
Brick-making method traditional at present has following 3 kinds：Clay brick is ripe with 50% mild-clay and 50% hard paste
Material, including the powder such as shale, flyash, gangue carry out dispensing by certain granularity requirements, handle, are molded through pug, drying
Afterwards, it is calcined and forms at a high temperature of 1300-1400 DEG C.The drawbacks of its is maximum is that its production process will expend substantial amounts of clay,
And large area soil is taken so that it produces needs, cause a large amount of losses of cultivated land.To protect land resource, at present, China
Land occupation has been forbidden to produce clay brick.Dinas brickes is lime, quartz sand, sand or packsand in appropriate proportions, through overground
Carefully, plus water mix, semidry method are compressing, and are formed through steam press maintenance, and flyash brick is the incorporation using flyash as main material
Colliery powder, or the cementing material such as clay, are made through dispensing, shaping, drying, roasting, and both brick-making method raw material are complicated
It is various, it is necessary to by steam press maintenance and roasting can be made, complex process.
The content of the invention
It is an object of the invention to provide one kind make it is simple, easy to operate, without steam press maintenance and roasting process, can be with
Save the energy, reduce brick making cost, accomplish waste secondary use the method using CHARACTERISTICS OF TAILINGS SAND brickmaking.
The preparation method of the present invention is as follows：
1st, raw material
Portland cement, CHARACTERISTICS OF TAILINGS SAND, HWR types water reducer and water, the mass percent of above-mentioned raw materials are：Cement 60-
65 parts, CHARACTERISTICS OF TAILINGS SAND 15-20 parts, HWR type water reducer 0.5-0.7 parts, water 17-20 parts；
2nd, brickmaking
Above-mentioned raw materials are added while stirring, after water all adds, continue to stir 2min；The compound being stirred is put
In the mould for entering advance oiling, and the 1min that vibrates is placed on the platform that vibrates, is put into natural curing in fog room, form removal after 24h.
The present invention has the following advantages that compared with prior art：
1st, manufacturing process is simple, and mode of operation is easy, conserves after shaping, is supported without steam pressure under field conditions (factors)
Shield, roasting process, the energy can be saved, reduce brick making cost.
2nd, raw material are done with industrial waste tailings sand, can not only alleviates a large amount of land occupations of CHARACTERISTICS OF TAILINGS SAND, difficult management,
The present situation of environment is polluted, also accomplishes the secondary use of waste, turns waste into wealth, while substitutes a certain proportion of cement, is substantially reduced
Cement consumption and cost.
3rd, the compression strength 52.9Mpa of the brick prepared, rupture strength 3.95Mpa, is satisfied by JC/T422-2007《It is non-sintered
Rubbish tailing-bricks》Code requirement.
