| 中文摘要:高纯石英、高纯石英原料与高纯石英原料矿, 三者概念不同, 不能混淆。高纯石英是选矿之后的矿产品; 高纯石英原料是野外工作大致能判断的、可以作为高纯石英选矿原料的矿石; 而高纯石英原料矿是有可能从中圈定出高纯石英原料矿石、矿体的矿种, 包括石英砂、粉石英、石英砂岩、石英岩和脉石英矿 5个主要矿种。当前我国寻找“高纯石英原料”的主要方向, 除了这5个矿种之外, 还要注意这5个矿种在特定条件下形成的矿床类型。比如, 稳定地台区形成的石英岩, 经过区域变质之后的石英岩矿; 变质石英岩风化之后的粉石英矿; 白岗岩、翁岗岩、碱性花岗岩建造风化壳以及由其风化产物形成的石英砂; “干环境”中形成的脉石英等。 |

| Abstract:The concepts of high-purity quartz (HPQ), high-purity quartz ore and high-purity quartz deposit are different and should not be confused. HPQ is the mineral products after beneficiation; HPQ ore is the ore which can be identified roughly by field work and can be used as the raw materials of HPQ beneficiation; HPQ deposit is possible to delineate HPQ ore and ore body species, including quartz sand, powder quartz, quartz sandstone, quartzite and vein quartz 5 main minerals. At present, efforts are mainly directed toward finding HPQ ores, in addition to these 5 minerals, as well as identifying the types of deposits formed by these 5 minerals under specific conditions. For example, quartzite formed in stable platform areas, and quartzite deposits after regional metamorphism; powder quartz after weathering metamorphic quartzite; quartz sand formed from weathering crust of albitite, ongotite, and alkaline granite, and their weathering products; and vein quartz formed in the “dry environment”. |
