Iron oxide in silica sand. AppNote XRF1177: analysis of iron oxide in silica sand. Background. One of the major uses of silica sand is to make glass, and in particular glass bottles. The iron content is one of the major factors that affects the color of the glass. Low iron sands are used to produce clear glass for bottles, while sand with higher iron content is used to make amber glass bottles ...
· Removal of As(III) by FeScoated sand was 30% of that by nanoparticulate FeS at pH 5 and 7. At pH 9, the relative removal was 400%, perhaps due to the natural oxide coating of the sand or a secondary mineral phase from mackinawite oxidation. Although many studies have investigated the coating of sands with iron oxides, little prior work reports ...
· Fly ash is a byproduct from burning of coal. Utilization of fly ash by carbothermic reduction is an effective way to recover aluminum, silicon, and iron to enhance productadded value. This work is focused on the phase transformation of Al2O3, SiO2 and Fe2O3 during carbothermic reduction of fly ash in air. A comparative analysis of carbothermic reduction of fly ash in air and in nitrogen was ...
