Example Embodiment

[0026] Example 1

[0027] Taking the fine-grained quartz sandstone minerals in a certain place in Sichuan as an example, see the pictures of the original ore. figure 2 .

[0028] The method of the present invention, namely a method for purifying fine-grained quartz sandstone to prepare materials for ultra-white glass, is characterized by comprising the following steps:

[0029] a) Crushing: crushing the quartz sandstone ore below the target size in preparation for sorting and further processing;

[0030] b) (hindered or) screening: control the upper limit of the particle size of the crushed products, and provide suitable grinding particle size for the grinding operation;

[0031] c) Grinding: fully dissociate the quartz sandstone minerals to meet the target particle size requirements;

[0032] d) Pre-screening or inspection: control the particle size of quartz sandstone below the upper limit of the target particle size;

[0033] e) Classification: control the lower limit ...

Abstract

The invention relates to a method for preparing an ultra-white glass material by purifying fine-grained quartz sandstone. The fine-grained quartz sandstone is subjected to crushing, (hindered or) screening, ore grinding, advanced or inspection screening, grading, magnetic separation, ultrasonic dissociation-medium scrubbing-grading (desliming and reagent removal), acid flotation-reagent removal, high-temperature dynamic leaching-concentration-cleaning reagent removal and dehydration; the content of Fe2O3 in fine-grained quartz sandstone minerals which are extremely difficult to select can be reduced to be smaller than or equal to 100 ppm, the quality requirement of high-quality quartz sand for ultra-white photovoltaic rolled glass is met, the source of siliceous raw materials for the ultra-white photovoltaic glass is expanded, reasonable utilization of fine-grained quartz sandstone mineral resources is realized, and resource waste is reduced; and meanwhile, media used in the method are thinning waste liquid for etching in the field of information display, the utilization rate of the media is increased, the cyclic utilization rate of wastewater can reach 90% or above, and sewage discharge and treatment cost is reduced.

Description

technical field [0001] The invention relates to a method for beneficiating quartz sandstone minerals, in particular to a method for purifying fine-grained quartz sandstone to prepare materials for ultra-white glass. Background technique [0002] Fine-grained quartz sandstone is a kind of sedimentary rock formed by cementing and solidifying quartz particles (0.125mm~0.25mm content of more than 50%) through silica, clay, iron, chlorite, etc. Quartz sandstone in Sichuan and Hunan Resource reserves of more than 2 billion tons. The grade of raw ore is generally low, the dissemination is serious, and the iron-containing siliceous cement penetrates into the gaps of sandstone particles, which is difficult to dissociate within the particle size range of conventional glass materials (0.1mm~0.71mm); feldspar, tourmaline, garnet, hematite It is also very difficult to selectively capture the associated impurity minerals such as ore and pyrite because they are cemented and wrapped by sil...
