During mining operations, metallic ores and other inert materials are extracted from the ground and are usually stored in the surroundings of the mine. Those materials create a negative environmental impact and lose all their potential to be processed and produce valuable products. These waste materials (tailings) have different granulometry and are mainly composed of silica and smaller amounts of calcium oxide, magnesium oxide, aluminum oxide, and more. Silica can be used to produce different kinds of glass, such as flat glass products, bottles, or others that require different compositions and prices. However, the current materials found in tailings require a reprocessing to eliminate impurities at a reasonable cost.
