Uralian ultrapure quartz is a world-class raw-material source for making transparent quartz glass with unique properties: total content of all impurity elements (Al, Fe, Ca, Mg, Na, K, Ti, Li, B, Cr, Ni, Mn, Cu) in the beneficiated quartz concentrates does not exceed 10 ppm and the total content of alkali elements (Na, Li, K) is in the range 0.37 – 0.94 ppm. Such metrics are achieved thanks to the natural features of quartz of metamorphogenic-metasomatic genesis and the beneficiation schemes developed for it. Resources of this kind are concentrated within the Kyshtym deposit of granular quartz in the Urals.

乌拉尔超纯石英：制造透明石英玻璃的原材料来源

乌拉尔超纯石英是制造具有独特特性的透明石英玻璃的世界级原料，其特征是：所有杂质元素（Al，Fe，Ca，Mg，Na，K，Ti，Li，B，Cr，Ni，精选石英精矿中的Mn，Cu含量不超过10 ppm，碱金属元素（Na，Li，K）的总含量在0.37 – 0.94 ppm范围内。这些指标的实现归功于变质成因成因石英的自然特征以及为此开发的选矿方案。这种资源集中在乌拉尔的粒状石英Kyshtym矿床中。
