Abstract
Based on the feature that iron ions exist in the surface of and inside the cracks in the quartzite and water exists on the surface of quartzite to shield the iron ions inside cracks, quartzite is stoved to remove water, mixed with concentrated hydeochloric acid to make hydrochloric acid enter into cracks. The method can product high grade quartzite.
Description
The present invention relates to a kind of higher quartz sand deironing working method of ferric oxide that contains.
The method of the quartz sand deironing of China adopts the magnetic ore dressing at present, and dilute hydrochloric acid is washed the method for washed ore, but can not remove the intracrystalline iron ion of quartz sand, its this method cost height, and contaminate environment can not reach satisfied de-ferrous effect.
The objective of the invention is the quartz sand deironing that iron-holder is high and be processed into highly purified quartz sand.
The present invention realizes according to following method.
The iron of quartz sand mainly is with Fe
+ 2, Fe
+ 3Ionic species is present between quartz sand plane of crystal and the crystalline crack; under the surface tension protection of water; general pickling can't reach between the crack; present method is: moisture content is removed in the quartz sand oven dry after, will eluriating; add concentrated hydrochloric acid; hydrochloric acid enters among the slit and crystalline crack between quartz sand crystal and the crystal, and concentrated hydrochloric acid at first is the dissolved iron ion, generates the volatilization of iron protochloride and iron trichloride then.Two, with twenty four hours behind the mixed concentrated hydrochloric acid of dry sand or 48 hours, not evaporable iron(ic) chloride, aluminum chloride, calcium chloride, magnesium chloride etc. were removed in the water flushing, reach highly purified silicon-dioxide (quartz crystal).
The inventive method can make iron-holder by 1.2% yellow quartz sand, and iron-holder drops to below 0.02%, reaches the purpose of deironing.Quartz sand after the deironing can be used for making high glass, crystal glass, optics, laboratory glass wares, pharmaceutical glass, advanced ceramic glaze, frit etc., helps reducing environmental pollution, reduces production costs, and is very practical in the area that does not have high-quality quartz sand.
Claims (3)
1, the working method of this quartz sand deironing, its feature is that it comprises must dry (dry, all can dry) and remove moisture content, and is mixed with concentrated hydrochloric acid then, stack for some time after, water flushing, the purpose that reaches deironing and produce high-quality quartz sand.
2, the working method by the described quartz sand deironing of claim 1 is a basis: iron ion is present among the surface, crack, slit of quartz sand; wet quartz sand water molecules is under the effect of plane of crystal tension force; protected the iron ion among crack, the slit; quartz sand is removed moisture content; the principle that hydrochloric acid can be reacted with the iron ion among crack, the slit reaches the deironing purpose.
3, by the described quartz sand method for removing iron of claim 1, it is characterized in that dewatered quartz sand, must be mixed with concentrated hydrochloric acid, for some time is stacked in mixed back, makes its iron(ic) chloride volatilization and allows iron ion and hydrogenchloride react fully, water washes then, reaches the purpose of abundant deironing.
