Magnetic Separation in Sand Processing low enough iron content to enable production with little or no processing of the sand Silica sand 400 micron Silica sand . Low Iron Glass Ultra White Glass Glass Low iron glass is made from a high grade of silica sand that is almost completely free of iron oxides .
Best Sand's high-purity silica sand and gravel are widely used in the foundry industry. The sub-rounded grain shape is proven to reduce expansion defects in cores and molds of all casting types. Furthermore, the high silica content allows Best Sand to be used among steel foundries as well.
These include a high silica content in the form of quartz and, more impor-tantly, very low levels of deleterious impurities, particularly clay, iron oxides and refractory minerals, such as chromite. they typically have a narrow grain-size distribution (generally in the range 0.5 to 0.1 mm). for most applications, silica sands have to conform to very closely de-fined specifications, and ...
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. Thus, both at the quarry site and in the manufacturing process, monitoring the iron content ...
