Abstract
The present invention's gold concentrator tailings producing building material, make main raw material with gold concentrator tailings, add unslaked lime and gypsum behind a small amount of grinding, adding water in stirrer stirs, through digestion, secondary stirring, compression moulding, through heating up, boosting, the steam press maintenance of constant temperature and pressure and decrease temperature and pressure promptly makes needed plastics products for building in autoclave.Adopt difform mould can make difform goods, as building standard brick, hollow brick, paving brick, building block, kerb etc.
Characteristics of the present invention are directly to use to select the industrial waste that produces in the golden process---gold concentrator tailings, save land, energy-conservation, and the protection environment has good economic and social benefit.
Description
What the present invention relates to is the material of construction preparation field.
At present, the materials for wall of material of construction mainly contains two big classes: the one, by gelling material such as cement, magnesia, resin, all kinds of caking agent adds light skeletal or fiber is made; Another kind of is to make by hydration reaction with basic material (as cement, lime) and acid material (as flyash, sand, slag etc.).Above-mentioned materials for wall desired raw material mostly is manually to be made, and expense is higher, and minority (as clay brick) will expend a large amount of soils and fuel though do not use artificial raw material.
Aspect non-burning brick, existing slag, flyash and the cinder etc. of using are as raw material.The objective of the invention is to be to develop a kind of new industrial waste-gold concentrator tailings and produce material of construction.In selecting golden process, produce a large amount of mine tailings.The stacking of generally need building a dam of these mine tailings.Like this, not only need the huge fund of building a dam, lost a large amount of soils simultaneously, and surrounding environment is polluted, the present invention tries hard to address the above problem.
Originate in the gold mine in grouan and the shatter belt thereof, grade is generally less than 3～5 gram/tons, and the composition of gold concentrator tailings almost completely is equal to raw ore, and its granularity accounts for 40～70% for what account for 30～60%, 0.15～2.0mm less than the particle of 0.15mm.Its main component is a quartz 40～70%, feldspar 20～30%, mica 3～5%, landwaste 5～10%.Wherein quartz generates C with lime generation hydration reaction in the hygrothermal environment of High Temperature High Pressure
2The SH needle-like crystal makes goods have certain mechanical strength.
Raw material weight proportioning of the present invention is as follows: gold concentrator tailings 85～90%, unslaked lime 10～14%, gypsum 0～1%.
The technical process that the present invention adopts is as follows:
1, feedstock production: unslaked lime (effective CaO content is greater than 60%) and gypsum grinding to granularity 0.088mm square hole sieve are tailed over less than 10%.
2, batching stirs: by proportioning gold concentrator tailings, unslaked lime, gypsum are mixed, add 8～15% water (weight percent) and stirred in biaxial rneader 1～3 minute.
3, digestion: the material that stirs was digested in slaking silos 2～4 hours.
4, secondary stirring: will digest good material and carry out secondary stirring with biaxial rneader, churning time 1～3 minute, and add suitable quantity of water, total water ratio is controlled to be 6～10%.
5, compression moulding: be pressed into needed goods on shaper, forming pressure is 10～20MPa.
6, quiet stopping: moulded products is placed on the dolly, stopped leaving standstill in the chamber 1～2 hour quiet.
7, steam press maintenance: goods are pushed in the autoclave, feed saturated vapor, increasing temperature and pressure 1～3 hour, constant temperature and pressure 4～6 hours, decrease temperature and pressure 1～3 hour.Keep interior 174 ℃ of still during constant temperature and pressure, vapor pressure is 8atm.
8, go out still: when reducing to air pressure in the still when being 1atm, open the still door, release finished product, place and to dispatch from the factory in 7 hours.
As requested, adopt different shaper and moulds can produce standard square for building, hollow brick, building block, floor tile, kerb, stepped plate, windowsill, highway isolated mound etc.
Because the present invention directly adopts the gold concentrator tailings that results from grouan and the shatter belt thereof to prepare material of construction, therefore, has saved the expense of constructing the gold concentrator tailings dam, has saved the soil, has eliminated the pollution of gold concentrator tailings to surrounding environment; Again owing to adopting the steam press maintenance technology in the preparation process, so energy consumption has also reduced.The present invention saves 3,000 ten thousand yuan of the expenses of building a dam if only in area, northern Shandong, Shandong general implementation, can economize 1500 mu of mine tailing storehouse occupations of land in 1 year, saves 15,000 ten thousand yuan of land requisition expenses, saves 4,000,000 yuan of effluent charge; Save clay brick simultaneously and ruin 3000 mu on ground, reduce 10000 mu in mine tailing infringement soil, saving the energy is 60,000 tons of standard coals.Therefore, the present invention is saving land, higher benefit is being arranged aspect the energy-saving and environmental protection.
When producing holllow building block, can reduce cost 20% than solid brick with the volume Master Cost with gold concentrator tailings.
Most preferred embodiment of the present invention:
1, steaming pressuring tailing brick
Per distribution ratio is a gold concentrator tailings 87% by weight, unslaked lime 12%, and the ratio of gypsum 1% cooperates raw material, and wherein the granularity of unslaked lime and gypsum tails over less than 10% for the 0.088mm square hole sieve.Effective CaO is greater than 60% in the unslaked lime.Through stirring, digestion, secondary stirring, compression moulding, quiet stopping and process such as steam press maintenance, make 240 * 115 * 53mm Modular building solid brick, technical indicator is as follows:
10 mean compressive strengths are 35.8MPa, and the monolithic minimum value is 32.1MPa; Folding strength is 5.87MPa, and the monolithic minimum value is 5.31MPa.
