silica sand production process - kaartje-sturen-met-artoek.nl

Through this process, silica becomes a sealant, an adhesive, or a lubricant. For it to become adequate to process food, Silica (SiO2) is reduced to silicon metal by coke in an arc furnace, to produce the Si precursor of the other chemical processes. The chemical process and production is dependent on the use of industrial sand.
