Description
Technical field
The present invention relates to a kind of gelling material, or rather, relate to pretreated mine tailing, be the travertine gelled material of main raw material preparation and their preparation method with this pretreated mine tailing.
Background technology
Mine tailing is one of solid waste of the present quantum of output maximum of China.Total quantum of output of the present annual mine tailing of China is 600,000,000 tons, and wherein 500,000,000 tons is iron tailings, and all the other are non-ferro metals debris, precious metal mine tailing and nonmetalliferous ore mine tailing.The accumulation volume of cargo in storage of China's mine tailing is 6,000,000,000 tons.Except that the mine tailing of the mine tailing of minority skarn type iron ore and part nonmetalliferous ore, SiO in the mine tailing of most iron ores and non-ferro metals debris and the precious metal mine tailing
2With Al
2O
3Therefore sum belongs to high sial system all greater than 50%.A large amount of tailings impoundment like this, not only occupy a large amount of farmlands, mountains and rivers, brought havoc for environment and ecology, but also can be because mine tailing storehouse overload operation or mismanagement cause dam-break accident, bring massive losses and catastrophic environmental accident to the people's lives and property.Utilize mine tailing to prepare the existing a large amount of patent application of cement class gelling material of high calcium system both at home and abroad.Chinese patent publication number 200310109672 relates to the method that a kind of metal tailings (skarn) is produced cement or cement products, wherein disclose and added in the cement manufacturing that 10～35% metal tailings (skarn) are produced cement as blended material and part replaces the method for manufacture of cement cement products, but still continued the basic manufacturing process of traditional high calcium system cement.Chinese patent publication number 011302336 relates to a kind of Portland clinker, wherein disclosing a kind of is the method that the raw material of the batching of raw material is made cement clinker with Wingdale, iron tailings, flyash, boiler bottom slag, still belongs to a kind of manufacture method of traditional high calcium system silicate cement.Chinese patent publication number 96109194 relates to a kind of recovery method of tailings of iron ore, wherein mine tailing is made FeCO by being calcined to 400～800 ℃
3Be transformed into Fe
3O
4The method of iron is reclaimed in magnetic separation again, simultaneously the CaCO in the mine tailing
3And MgCO
3Be converted to CaO and MgO, kaolinite is transformed into metakaolinite, thereby the remainder after the magnetic separation has hydraulically active, as the raw material of producing cement of low index.This technology of inventing disclosed production cement of low index has been continued to use in traditional cement with the thought of chainotte as active addition of cement.Chinese patent publication number 92106479 relates to and utilizes the copper mine tailing to produce cement clinker, wherein with copper mine tailing 5～9%, Wingdale 71～80%, clay 4.5～6.5%, hard coal 6% is produced cement clinker as the batching of raw material, and wherein the main effect of copper mine tailing is the instead of part clay, and SiO is provided
2, and have certain mineralizer effect, its technological line still to continue to use the technological line of traditional portland high calcium system.
Publication number is that 02158190 patent of invention " coagulating stone dualization wet cement and uses thereof " has been described and adopted big volume waste residue wet method to prepare the method for travertine gelled material, earlier material is not carried out pretreated technology but introduce the principle that adopts hydrothermal alteration, do not comprise with the mine tailing being the technology that main material production is coagulated stone yet.
The method of hydrothermal alteration of the present invention is invented according to hydrothermal alteration action principle in the geologic function.Hydrothermal alteration is ubiquitous in geologic process, is the most important effect that mineral composition changes in the earth's crust.Hydrothermal alteration on the fugitive constituent group just deviate from have strong polarity, advantage of high activity in a flash, act on the mineral grain surface, lattice surface is acutely destroyed, scission of link increases, reactive behavior improves, for subsequently corrosion, depolymerization, migration lays the first stone.The intensity of this hydrothermal alteration can also increase substantially under the compound synergistic effect effect of many components salt.
The present invention relates to a kind of the reaction mine tailing is carried out can using mine tailing (can reach more than 70%) by vast scale after the pre-treatment, mix (below 30%) or not water mixing mud grog less, produce the technology of travertine gelled material with cement of high index performance by hydrothermal alteration.
Summary of the invention
The present invention coaches with the stone theory of coagulating of imitative ground diagenesis, and the hydrothermal alteration process of particularly imitating in the geologic function is carried out pre-treatment to mine tailing.Pretreated method is: with mine tailing 30～90%, add 0.1～8% and contain K
