Quartz (silica, SiO 2) is the core mineral within the Sibelco group and can be found in a broad number of applications, such as glass, ceramics and polymers. When just processed to obtain a certain granulation, but not milled nor calcined, the products are called Silica Sand M. When milled and dried, the products are referred to as Quartz flour ...

To reduce particle size and remove the impurities of the raw sand, it was milled at 500 rpm for 36 h. After ball milling, the sand was then subjected to a purification process. Three methods were employed to purify the postmilled sand. In the first method, HCl hydrothermal treatment was used to remove impurities.

Quartz is melted together with steel scrap and a reductant. A hot liquid alloy is formed and collect in a sand bed. Once cooled the product is broken into smaller pieces, which will then further be crushed to the desired size. Ferrosilicon can contain varying silicon content, depending on the production process and needs.
