Column chromatography is frequently used by organic chemists to purify liquids (and solids.) An impure sample is loaded onto a column of adsorbant, such as silica gel or alumina. An organic solvent or a mixture of solvents (the eluent) flows down through the column. Components of the sample separate ...

Aluminosilicate refractories are manufactured using refractory clays, sillimanite minerals, bauxite, and mixtures of alumina and silica sand. They will refer, somewhat arbitrarily, to common crystalline compounds with melting temperatures of at least 1500 °C .The major categories of traditional refractories are fire clays, high alumina, and silica.

This study investigates the removal of silica and alumina as impurities from hematite based low-grade iron ore containing 34.18 mass% iron, 31.10 mass% of silica and 7.65 mass% alumina. Wet high-intensity magnetic separation (WHIMS) and reverse flotation (RF) were investigated. In WHIMS process, 93.08% of iron was recovered with a grade of 53.22 mass% at an optimum magnetic density of 10,000 ...

FIELD OF THE INVENTION. The present invention refers to a process of purifying silica sand and, more particularly, it is related to a process for removing, from silica sands which are to be used as a raw material for glass manufacture, ceramics and the like, practically all of the iron and aluminum impurities contained therein.

capacities of silica sand and anthracite coal were all lower than activated alumina, so experimental initial concentration was set at low level. Six water samples with phosphorus concentration 100μg/L, 200μg/L, 300μg/L, 500g/L, 800μ μg/L, and 1000μg/L were pre-pared for silica sand experiment, and 50μg/L, 100μg/L,

Fused silica is high purity quartz sand that has been melted to form glass. High volume stability, low volumetric expansion and high purity make fused silica a very useful and versatile material for refractory applications, whether in aluminum launders or other highly cyclical applications.
