What is the silica content of quartzite ore from 99 to 99.6?

The silica content of quartz stone raw ore is 99-99.6, which is a high-purity quartz stone raw ore. According to relevant public information, silica, also known as quartzite, generally refers to natural quartz sand with high purity, namely silica, which is widely distributed in nature and has large reserves. Many countries have large-scale high-quality mines. The main component is 99.5-99.7% silica, which is a white or light red massive ore, originating in Guizhou. It is mainly used to produce ferroalloy products such as ferrosilicon and ferromanganese, electronic products and silicon chemical products. The output is very small and very precious.
