Skal ikke glemme denne gullgruva heller:)

Although quartz is one of the most abundant mineral present on the Earth, very few naturally present deposits with 99.995% of SiO2 are considered as high purity quartz (HPQ). The constitution of remaining 0.005% is an important aspect that concerns the manufacturers as well as end-users equally. As the purity standards set by the International Ophthalmic Technology Association (IOTA) is a high benchmark to meet, there are only a handful of manufacturers operational in the global market that include Unimin Corporation, The Quartz Corp, Russian Quartz LLC (Kyshtym Mining), HPQ Silicon Resources Inc., Nordic Mining ASA, High Purity Quartz Pty Ltd, and Jiangsu Pacific Quartz Products Co., Ltd.
