About Northern Silica. Moberly involves an integrated mining and processing operation. The Moberly deposit is a largescale and highgrade quartzite silica ore body loed on the slopes of Mount Moberly, approximately 7km due north of Golden. The deposit is uniquely highgrade with an average grade SiO2 content of %.
Those people that may have been exposed to silica and contracted silicarelated respiratory injuries would most likely have been inhaling tridymite or crystobalite in the dust after the explosions. Those people in and around the collapse of the World Trade Centers in 2001 would mostly be inhaling quartz coming from the concrete dust. The point is simple. Although all are different in chemical ...

Answer (1 of 4): To a geologist or mineralogist, "silica" only means a SiO2 compound, regardless of its actual crystal structure. If you had pure SiO2 glass, you could describe it as being made of silica, and you can say that chemically, pure quartz is also SiO2. In quartz sands, the SiO2 is arra...
