A Critical Review on the Mineralogy and Processing

2020-6-22  Among these techniques, pressure leaching is the most widely used and effective technique for high-grade quartz processing. In general, quartz sand is calcined at 700~900 °C, and then leached by fluoric solutions or acid-NH 4 Cl solutions. The leaching agents are diffused into the quartz interior along micro-cracks caused by calcination.
