| 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 roughlyby field work and can be 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, the main direction of looking for HPQ ore, in addition to these 5 minerals, but also pay attention to 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; vein quartz formed in the "dry environment", and so on. |
