Abstract
A kind of ceramic tile for building, with the gold ore tailing is the main raw material of blank, wherein the consumption of gold ore tailing accounts for 70-80% of batching total amount, blank medium clay soil consumption only accounts for about 20% of blank total amount, batching is simple, not only reduces the comprehensive utilization that the clay consumption more is mainly for gold ore tailing and has found an approach that industrial value is arranged, and has created wealth, reduced tailings and piled up and take up an area of and, and tangible economic benefit and social benefit arranged the pollution of environment.
Description
The present invention is relevant with building and ornament materials, is the improvement technology of producing about ceramic wall and floor bricks.
Gold ore tailing is the waste material that the gold mine ore is discharged after the fine grinding ore dressing, after the gold mine preparation of ore per ton, approximately needs to discharge 0.85～0.901 ton of tailings.For a long time, these tailings are adopted the sky mineral building except that part backfill down-hole, and a big chunk tailings will be built the mine tailing storehouse and pile up, and not only spends a huge sum of money.And to take large quantities of farmlands, line service is heavy in addition, brings heavy burden to mine production and operation, and brings pollution to surrounding environment.
This tailings contains multiple compositions such as silicon-dioxide, alchlor, ferric oxide, calcium oxide, magnesium oxide, is a kind of of great value natural resources.Though many R﹠D institutions are arranged for many years to be studied the comprehensive utilization of gold ore tailing.Do not utilize gold ore tailing to make the ceramic wall and floor bricks problem but all relate to.And common ceramic wall and floor bricks is to be main raw material with the clay, and the clay consumption accounts for about 50% of blank total amount, is equipped with auxiliary materials such as quartz in addition again.
The object of the present invention is to provide a kind of technology of utilizing gold ore tailing to make ceramic tile for building.
The production technique of the ceramic tile for building that the present invention proposes.Be to be that main raw material is equipped with clay and other additives again and fires and form with depleted tailings in the gold mine production, wherein the consumption of gold ore tailing accounts for the 70-80% of batching total amount, here the clay consumption only accounts for about 20% of blank total amount, other additive such as flint clay powder can not add or add less according to the Chemical Composition of gold ore tailing.Do not need to add again components such as quartz, so it is much simpler than blank formulations such as existing ceramic wall tile, three bent tiles that blank of the present invention is formed, the proportioning of blank of the present invention is formed (weight %): 70-80 part gold ore tailing, 12-25 part clay, 0-8 part flint clay powder.
The production technique of ceramic wall and floor bricks, process such as comprise batching, granulation, old, compression moulding and burn till, processing condition change because of the difference of batching.Because the present invention is with the main ingredient of gold ore tailing as blank, omitted operations such as mining in the common ceramic tile production, fine grinding and reduced energy consumption.This tailings is the product of flotation behind the ore ball milling, and particle diameter is thin, retaining power is strong, though there is plasticity to belong to low moulding material.The high loss on ignition of dioxide-containing silica is less in the tailings, so the principal feature of production technique of the present invention is:
A, blank granulation.Blank is pressed into the preceding dehydration earlier of base substrate of certain configuration.The blank that oven dry will be dried to required moisture again is prepared into suitable viscosity particle powder, generally all come granulation with crushing mill, blank is rolled over by wheel and is obtained closely knit false particle, make portion gas and moisture discharge in the blank, the particle of blank granulation in the present invention, granularity are controlled between 150 microns to 1 millimeter approximately.
B, old blank.Blank after the granulation also must be through an old process, and the effect by kapillary and vapour pressure of its objective is makes in the blank moisture uniform distribution more.Abundant aquation of blank particle and ion-exchange in old process, thus plasticity-improved, improve the processability of blank.Process characteristic of the present invention is that the old time of blank is longer, and the general old time is 36-48 hour, and blank is fully seeped water and exhaust.
C, extrusion forming.Ceramic tile is because shape is regular, dimensional requirement is strict, must use the pressing moulding, and along with pressure increases, gas is excluded in the loose powder in the compression moulding process, and solid particulate is compressed to be drawn close, and blank forms base substrate.The water ratio of blank is 5-6% in the present invention, with a kind of uneven pressure that increases progressively granular blank is done repeatedly extrusion forming with 100 tons of pressing machinees, make pressure uniform distribution in base substrate, pressurized air is fully discharged in the base substrate, obtain fine and close adobe, its maximum forming pressure is 500kg/cm
2
D, burn till.After the base substrate drying after the moulding, adopt double-firing process to burn till.The control firing temperature is 1050-1180 ℃, and base substrate enters the mouth from stove, and beginning slowly heats up gives heat, slowly cools to the stove outlet after burning till again, uses than long firing time to improve the qualification rate of finished product.
By prescription provided by the invention and technology, can produce products such as ceramic wall and floor bricks or three bent tiles with gold ore tailing.
Detect through construction sanitary ceramic quality inspection station, Shandong Province according to production technology products obtained therefrom performance of producing ceramic wall and floor bricks with gold ore tailing provided by the invention, reach the GB11947-89 requirement, its flexural strength is greater than 30MPa, and water-intake rate is 4.3%.
Use a simple technical flow synoptic diagram below again, the invention will be further described.
Accompanying drawing is a process flow diagram of the present invention.
I is that blank mixes process among the figure, gets 75 parts of CHARACTERISTICS OF TAILINGS SAND and 25 parts of clays mix, and the consumption of flint clay powder is decided according to the CHARACTERISTICS OF TAILINGS SAND composition, and what have can not add flint clay. The blank that mixes is delivered to take turns in 2 to roll over and is played the powder granulation, impels portion gas in the blank Discharge with moisture. Placed old about 48 hours, and made blank continue the infiltration exhaust. The 4th, the blank moulding. With 100 tons of repeatedly extrusion formings of friction press, the base substrate after the moulding is sent in the roller kilns after super-dry, 1120 ℃ of lower biscuitings through old blank. Glaze mixes 10 with raw material through batching in addition, behind grinding 11 and the glaze old 12, sends to the base substrate after the biscuiting is carried out glazing 6, thereafter again through a glaze firing 7, obtains building ceramic wall ground brick product and meets the GB11947-89 standard.
Advantage of the present invention is clearly, and the present invention makes the gold ore tailing resource again obtain being utilized as rationally to utilize gold ore tailing to find a new approach that industrial value is arranged. Make ceramic tile for building with tailings, both created wealth, also reduced the pollution of tailings to environment, for the descendants benefits. After tailings is utilized, saved the investment of building Tailings Dam, can reduce again tailings and pile up occupation of land. Substituted 80% ceramic raw material energy efficient with tailings in addition in ceramic tile production, minimizing clay consumption also can reduce the destruction to the soil, and the present invention has obvious economic benefit and social benefit in a word.
Further specify the present invention with several examples more below, but be not confined to this several example ranges.
