Silica Quartz mine is situated outside Delmas, on the border of Mpumalanga and Gauteng. In operation since 1972, Silica Quartz is among the largest producer of high-quality silica in South Africa, used primarily in the production of glass and graded sand. The operation comprises an open pit, crushing, wet and dry screening processing plants for full beneficiation. Since purchasing the mine in 2006, Silica Quartz now boasts a 100 ton-per-hour production plant. Despite the impressive speed of production, our product is always carefully recovered with the awareness that what we do, and how we do it, affects our surroundings.
