Silica sand low in iron is much in demand for glass, ceramic and pottery use, and for many of these applications clean, white sand is desired. Impurities such as clay slime, iron stain, and heavy minerals including iron oxides, garnet, chromite, zircon, and other accessory minerals must not be present.
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.
This paper deals with the removal of iron from silica sand in aqueous oxalic acid, in the absence and presence of ultrasound. The parameters investigated were the reaction temperature, stirring speed, ultrasound power, acid concentration and reaction time.
Silicon-aluminum alloys tend to have relatively low strength and ductility, so other metals, especially magnesium and copper, are often added to improve strength. In the chemicals industry, silicon metal is the starting point for the production of silianes, silicones, fumed silica, and semiconductor-grade silicon.
