properties alone, silica sands are valued for a combination of chemical and physical proper-ties. These include a high silica content in the form of quartz and, more importantly, very low levels of deleterious impurities, particularly clay, iron oxides and refractory minerals, such as chromite. They typically have a …
17-06-2020· And it is this demand for silica sand (SiO2) that might prove to be a bit of a stumbling block. While silica sand is the most abundant mineral on the planet, it is still a finite resource. This is because high purity sand is required for making both flat glass and container glass as impurities such as sulphides and iron will cause imperfections.
