Abstract
The invention relates to limestone tailing-bricks and a preparation method thereof, which solves the problem of the maximization comprehensive utilization of the limestone tailings. The preparation method of the limestone tailing-bricks is as follows: dehydrating the limestone tailings and controlling water content thereof to be less than or equal to 15%; again dehydrating and controlling water content thereof to be less than 5%; clearing lumps with grain size larger than or equal to 5 millimeter; blending and controlling silt content to be 20-50% of the total weight; blending the limestone tailings with grain size less than 5 millimeter, the limestone coarse aggregate or the coal ash, and the firming agent; watering and uniformly stirring; controlling the weight percentage of the blended raw materials thereof to be 6-11%; brick making and maintaining. The invention enlarges the raw material source of the brick making, causes the limestone tailings to be fully used, solves the problem of stockpiling occupying land resources; and the prepared building bricks are in line with the national standard, has simple technique, stable quality control and low production cost.
Description
Technical field
The present invention relates to a kind of building brick, specifically belong to the brick and the preparation method that adopt limestone tailing to make.
Background technology
In the recovery process of limestone mine, because of containing earth in the ore, in order to obtain to have the limestone finished product ore deposit of certain particle diameter and concentrate grade, often to carry out operations such as fragmentation, screening, washup to the limestone raw ore of exploiting, there is the limestone tailing of raw ore output about 5~10% to produce approximately, these mine tailing compositions also contain compositions such as a certain amount of earth based on limestone.These mine tailings can only be stored up in the mine tailing storehouse, have not only taken land resources, and environment has also been caused certain harm.In order to ensure the safe operation in mine tailing storehouse, also need to drop into great amount of manpower and material resources it is monitored and safeguards.
The utilization of limestone tailing has two approach, and the one, increase the ore dressing dynamics, improve the rate of recovery of concentrate, reduce the productive rate of mine tailing; The 2nd, isolate in the limestone tailing+particle of 0.5mm, be applied in aspects such as building concrete, building mortar as building sand, also there are some mines to do concrete brick with above-mentioned building concrete, building mortar.But existing limestone tailing utilizes approach to have following problem:
After improving the rate of recovery of mine tailing and extracting the mine tailing coarse granule, still have the fine tailings more than 50% to produce, wherein mud content is up to 20~60%; Generally can only store up, be difficult to utilize in the mine tailing storehouse.
A spot of limestone tailing is applied in building concrete, the building mortar as building sand, its cost height, and can not solve fully the residue tailings discharging, store up problem.
Summary of the invention
The objective of the invention is to solve present limestone tailing utilization rate low, store up deficiencies such as serious, provide a kind of limestone tailing utilization rate can up to 95% or more until all, need not the land occupation resource, realization is made building brick and composition and the simple limestone tailing-bricks of preparation method and preparation method thereof with limestone tailing.
Realize the technical scheme of above-mentioned purpose:
A kind of method for preparing limestone tailing-bricks, its step:
1) limestone tailing is carried out processed, the water content of control limestone tailing is≤15%;
2) dewater once more, and the water content of control limestone tailing is<5%;
3) remove foreign material, promptly adopt sieve to remove the block of granularity 〉=5 millimeter;
4) carry out mixing, mixed mud content is controlled at 20~50% of gross weight;
5) be that 60~92% limestone tailing, percentage by weight are that 0~30% sandstone coarse aggregate or flyash and percentage by weight are that 8~10% sandy soil curing compound or HAS curing compound or HEC consolidating agent evenly mix with the percentage by weight of granularity<5 millimeter;
6) add water and stirring, the moisture content of controlling its mixed raw material is 6~11%;
7) carry out brickmaking and maintenance.
The present invention has compared with prior art not only enlarged the raw material sources problem of brickmaking, and limestone tailing-bricks is maximized the use, solved windrow land occupation problem of resource, the building brick of its making meets national standard, and technology is simple, quality control is stable, and cost of production is low.
