Abstract
Efficient separation of trace muscovite from the surface/interface of quartz grains was accomplished during oxidizing calcination and
catalytic pressure leaching of the hydrothermal quartz. Experimental results suggest that 98.97% or more of the muscovite was
separated when quartz sand was calcined at 900 °C for 5 h and then leached by hydrochloric acid and ammonium chloride solutions
as substitutes for leaching agents containing fluorides. The chemical processing techniques show high selectivity in purifying quartz
sand by transforming mineral muscovite into active structures during oxidizing calcination, and then dissolving the active substances
during catalytic pressure leaching
