天然粉石英以其不需碾磨直接获得高纯度的粉石英精矿并在工业上得到应用而引人注目。粉石英矿床是一种风化壳型矿床。粉石英是硅质岩风化后的最终产物。但由于风化作用强弱的不同,粉石英矿体中的粉石英和风化解体不完全的硅质岩残块(硅砂、硅石)所占比率也不同。另外,由于沿节理裂隙有泥砂及粘土充填,造成矿体被铁、泥质 Natural powder quartz with its direct access to high-purity powder quartzite grinding and industrial applications attract the attention. Powder quartz deposit is a weathered shell type deposit. Powdered quartz is the final product of weathered siliceous rocks. However, due to the different weathering intensity, the ratio of the powdered quartz in the quartzite and the incompletely decomposed silicalite residues (silica sand, silica) is also different. In addition, due to the fissures along the joints have silt and clay filling, resulting in ore body is iron, muddy
