Abstract
The present invention utilizes iron ore beneficiation depleted tailings, an amount of glass of admixture and a small amount of additive, through founding moulding, crystallization and thermal treatment makes the crystal glass series of dark color or green keynote, its crystallization phases＞50%, crystalline particle size 4-15 μ, the physical strength height, wear-resisting, chemical resistance, frost resistance is good, the coefficient of expansion is little, is a kind of novel building decoration and anti-chemical corrosion and high-abrasive material.
Description
A kind of method of utilizing iron ore tailings to make crystal glass relates to the manufacturing technology of crystal glass.
The report Soviet Union is arranged aspect the research and production of cinder microcrystalline glass, being developed into the blast furnace slag is the devitrified glass of main raw material, and has been used widely.In recent years, countries such as Britain, Japan, the U.S. are also obtaining remarkable progress aspect the research of cinder microcrystalline glass, for example, Britain done a large amount of research work in cinder microcrystalline glass crystallization mechanism and with cinder microcrystalline glass as aspect such as anti-corrosion pipeline.Slag glass ground, roofing and wall covering etc. have been studied in the research centre of Paris, FRA by Corning Incorporated.
At home,, be mainly used in and make wall floor tile and roofing tile, also carried out the preparation concrete in addition respectively with gathering materials the research and development of building sand aspect in the past to the comprehensive utilization of iron ore tailings.
The depleted tailings was made the fine crystal glass after the object of the invention was to utilize iron ore dressing.Through the analysis to adopting iron ore tailings, the chemical ingredients of iron milltailings is more stable, and it removes to contain and forms the required SiO of glass
2, also contain a large amount of ferric oxide outward,, can design the crystal glass prescription of a series of dark themes as long as add an amount of glass industry with common raw material such as quartz sand with after containing the raw material of alkali, alkaline-earth oxide and adding a small amount of additive.Contain abundant TiO in the tailings
2, sulfide and non-ferrous metal element, not adding under the nucleus agent condition, also can make the iron milltailings crystal glass of excellent performance.The fusible component that contains in the iron milltailings can make the reduction of glass smelting temperature and be easy to clarification, homogenize, saves the consumption of soda ash in the preparing glass charge.
Adopt iron ore stone sand tail to make crystal glass, for making selected glass ingredient that appropriate processing condition can be arranged and making the crystal glass that makes have the technical indicator and the application performance of specified requirement, the chemical composition range of iron milltailings crystal glass is:
Form SiO

Founding and moulding of glass:
Glass melting temperature is 1450-1500 ℃,
Mold temperature 1200-1350 ℃,
This glass is applicable to cast, multiple moulding process such as compression moulding
Crystallization and thermal treatment:
The fs nucleation temperature is 660-710 ℃, is incubated 1.5 hours
The subordinate phase crystallization temperature is 760-820 ℃, is incubated 1 hour
Be warming up to subordinate phase by the fs and need 1 hour approximately, finishing crystallization time is 4-5 hour.
Its crystallization phases of crystal glass＞50% that adopting iron ore tailings is made, crystalline particle size 4-15 μ, its performance is as follows:
Density 2.7g/cm
3
Folding strength 85-125MPa
Ultimate compression strength 600-700MPa
Resistance to impact shock＞2.5kg.cm/cm
2
Mohs' hardness 6-7, wear resistance＜0.03g/cm

Acid resistance (HCL37%))＞98%
Alkali resistance (NaOH20%)＞98%
Frost resistance-20 ℃-+20 ℃, freeze-thaw cycle＞15 time
Water-intake rate 0
Thermal expansivity (65-80) * 10

Embodiment one:
82 parts of iron ore tail sands
65 parts of quartz sands
30 parts of feldspars
26 parts of rhombspars
54 parts in Wingdale
5 parts of lithium marbles
5 parts of soda ash
Mix the back and melt at 1450 ℃ and promptly enter heat treatment furnace after making the glass metal casting, the fs nucleation temperature is 680 ℃ of insulations 1 hour, and heat up at a slow speed (3 ℃/minute) to 820 ℃ of insulations 1 hour, cooling was the uniform crystal glass of quality then.
The composition of glass is
SiO
