valuable minerals [15]. Gravity-flotation technologies for processing gold-bearing ores are a fairly common and ef-fective way of enriching mineral raw materials [16–19]. This article is devoted to the processing of low-sulfide gold-quartz ore using an integrated technology for the en-richment of mineral raw materials.
6. Pink Quartz Pink quartz ore is a natural powdered quartz deposit, which belongs to the new generation of siliceous raw materials and is derived from the weathering of microcrystalline quartzite. Its main component is microcrystalline quartz, and its appearance is white, light yellow white or grayish white.
The production process of high-purity quartz requires ore deposit raw materials with high grade, which are usually pegmatite quartz and hydrothermal vein quartz (Platias et al., 2013, Zhang and Chen, 2010a). At present, the global distribution of high-purity quartz raw material deposits is extremely scarce (Larsen et al., 2000).
After acid leaching, the quartz sand samples were washed three times with ultra-pure water and dried under vacuum in an oven at a temperature of approximately 120 • C for 0.5 h.
