Silica exists in ten different crystalline forms or polymorphs, quartz being by far the most common. Quartz is the second most common mineral on the earth's surface and it is found in almost every type of rock, i.e. igneous, metamorphic and sedimentary. Since it is so abundant, quartz is present in nearly all mining operations.
— "Now, our focus shifts to holding mining companies accountable." Silica is one of Earth's most abundant minerals, and it's about 20 times more toxic than coal dust. It's typical in the quartz that surrounds coal seams, especially in central Appalachia. Not just coal miners. Mining companies are being given time to adapt to the regulatory changes.
