近几年,江西省建材工业公司和当地地质部门在为本省寻找玻璃原料矿产资源过程中,在赣西的丘陵地带发现了我国特大的天然粉石英砂矿。粉石英矿床呈面型展布,矿体大多暴露地表,埋藏浅,剖面结构简单,适宜露天开采。矿储藏量丰富,各矿体纵深厚度为20～50 In recent years, the Jiangxi Provincial Building Materials Industry Corporation and the local geological department have discovered a large natural quartz quartz placer in the foothills of western Yunnan during the search for mineral resources for glass raw materials in the province. The powder quartz deposits are surface-typed, with most of the ore bodies exposed to the surface, with shallow burial and simple cross-section structures, which are suitable for open-pit mining. Mineral reserves are abundant, and the depth of each ore body is 20 to 50
