These types of glass contain between 70% and 74% silicon dioxide – the ultimate source of which is silica sand. The production of these specialist silica sands, particularly Low-Iron Glass Silica Sand for Solar Photovoltaic Panels, requires our specialist beneficiation and leaching equipment. This complex process will first involve a detailed analysis of your feed material both in terms of the particle size distribution (PSD) and the chemical properties of your silica sand.
