In July 2022 Sibelco announced the acquisition of Echasa a mining company engaged in silica sand extraction from the Laminoria quarry near Vitoria in the Basque Country Northern Spain located 160 kilometres away from Sibelco s nearest silica quarry in Arija This acquisition was aligned with Sibelco s 2025 strategy and its vision to
The most common form of SiO2 is quartz a chemically inert and relatively hard mineral SiO2 grades at a 7 out of 10 on Mohs hardness scale making it ideal for use as filtration media and abrasive blasting sands Silica Sand is quartz that through the work of water and wind has been broken down into tiny granules
Malaysia has an estimated resource of 640 Mt of silica sand of which 492 Mt from tin mine tailing sand and 148 Mt are natural silica Tin mine tailing sand was one of residue produced during the extraction of tin which the silica content is 94 %

Even though it would be in nature s best interest a worldwide ban on sand mining is not an option as the demand for sand is enormous and ever growing Gallagher and Peduzzi 2019 Between 1900 and 2010 the global demand for sand increased 23 fold Torres et al 2017 and it is expected to grow to a colossal 82 billion tons by 2060 Fritts 2019
Depending on how the silica sand was formed quartz grains may be sharp and angular or rounded For industrial use pure deposits of silica capable of yielding products of at least 98% SiO2 are required Silica sand may be produced from sandstone quartzite and loosely cemented or unconsolidated sand deposits
Lochaline silica sand mine in Scotland is the only underground sand mine in Europe comprising pure white sandstone extracted by room and pillar Lochaline has a long tradition of producing pure silica for applications and was renowned for the production of periscope lenses and gun sights during the war years
