    In the case of quartztype gold deposits, gold ore can be associated with pyrites both within the quartz vein and on the periphery (the alteration halo effect), as well as purely with the quartz material itself,– though generally in lesser concentrations. Dualphase particle sorting flowsheets have regularly achieved ore recovery

    Quartz is extracted by open pit mining, which involves extracting minerals from a burrow. Most of the time mining operations involve using bulldozers and backhoes to remove the soil and clay around the quartz to expose to the surface. On rare occasions, miners have to use explosives when the quartz they need to expose
