| Discussion on the Prospecting Direction of High-purity Quartz Deposit |
| 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”. |
