Description

Mine-filling cementing material and preparation method thereof
Technical field
The present invention relates to a kind of agglutinate and preparation method thereof, especially relate to a kind of mine-filling cementing material and preparation method thereof.
Background technology
Mine cemented filling is protection mining area ecological environment and the effective means that improves the Mineral resources utilization ratio, meet the amphitypy social requirement, so its range of application more and more widely.Mine cemented filling need adopt agglutinate that discrete aggregates such as the sand of beneficiation tailing, barren rock or other types, stone are consolidated into the adhesive bond with certain supporting capacity.The agglutinate that adopts is generally: the one, and cement, the 2nd, be the agglutinate that major ingredient adds fine grinding addition materials such as flyash, volcanic ash or levigated smelted furnace cinder with cement.Cement is to use the most general mine-filling cementing material, but cement is the all-purpose gum ramming material of building trade, as the application cost height of mine-filling cementing material, and the glued weak effect that higher beneficiation tailing filling is gathered materials for sulfur-bearing, the planar water ability is low; Is that major ingredient adds addition material and can reduce application cost as mine-filling cementing material with cement, can partly improves the adaptability of high-sulfur tailings and partly improve the planar water ability, but major ingredient is a cement, so the effect of improvement is restricted.Be applicable to the gather materials agglutinate with low cost of characteristic of filling in mine, be significant for applying the filling in mine technology.
Summary of the invention
The object of the present invention is to provide and a kind ofly can make waste resource recovery, the resisting erosion of sulfate ability is strong, cementing power good, cost is low mine-filling cementing material and preparation method thereof.
This mine-filling cementing material provided by the invention, comprise following raw material by weight: through ironmaking Water Quenching Slag 75～85%, stimulator 15～22%, the toughener 0～5% of water quick cooling processing, described stimulator comprises unslaked lime or white lime, wherein CaO content accounts for 70～80% of siccative part by weight, described toughener comprises gypsum, and the levigate granularity of described raw material is no more than 12% for+0.071mm proportion.
A kind of method for preparing above-mentioned mine-filling cementing material provided by the invention comprises the steps:
(1) will smelt iron the oven dry of Water Quenching Slag, unslaked lime and toughener, the toughener that is 75～85% ironmaking Water Quenching Slag, 15～22% unslaked lime and 0～5% is by weight prepared burden, dry grinding is prepared into the agglutinate siccative, perhaps will smelt iron Water Quenching Slag, unslaked lime and toughener and dry grind respectively, again with the material after levigate by weight: 75～85% ironmaking Water Quenching Slag, 15～22% unslaked lime and 0～5% toughener are mixed with the agglutinate siccative;
(2) store described agglutinate siccative standby.
The method of the above-mentioned mine-filling cementing material of another kind of preparation provided by the invention comprises the steps:
(1) will smelt iron Water Quenching Slag, unslaked lime or white lime and gypsum in dry weight ratio batching, and wherein smelt iron Water Quenching Slag 75～85%, stimulator 15～22%, toughener 0～5%, adding the water wet-milling becomes the mine-filling cementing material slurry;
(2) described agglutinate slurry is used immediately.
The invention has the advantages that:
(1) the ironmaking Water Quenching Slag is the waste material that dumps in the iron manufacturing process, and its utilization can be saved cost as the main raw material(s) of agglutinate, realizes the efficient resource utilization of waste material.
(2) mine-filling cementing material of the present invention and metallic ore flotation tailings are mixed the cemented filling material slip that forms of system, have that higher characteristics of mechanical strength and absorption water retention capacity are strong, slip do not need good performance characteristics such as the low and slip good leveling property of the threshold concentration of dewatering.
(3) erosion of vitriol can cause the loss of cemented filling material intensity.The gel of calcium silicate that aquation generated of Water Quenching Slag agglutinate of the present invention is more, and the slurry density is good, thereby the resisting erosion of sulfate ability is strong.Therefore, adopting the Water Quenching Slag agglutinate to combine with high sulfur-bearing tailings material, have better cementing power than ordinary Portland cement, is a kind of agglutinate more even more ideal than cement gel ramming material in filling in mine.
(4) preparation method of mine-filling cementing material of the present invention does not need raw material is calcined, and has simplified preparation technology, has saved the energy and manufacturing cost.
