α-Quartz is found in trace to major amounts in most rock types (e.g. igneous, sedimentary, metamorphic, argillaceous), sands, and soils. The average quartz composition of major igneous and sedimentary rocks is summarized in Table 10 of the previous IARC Monograph . Quartz is a major component of soils, composing 90–95% of all sand and silt ...
A crushed quartzite plant was chosen for sampling since quartzite represents the average in the metamorphic scale between sandstone and quartz formation. In this manner, a more representative free silica content, the initial pollutant of primary concern, would be encountered.
The most common use of quartzite is for dimensional stones in the construction industry. While construction also uses quartzite as crushed stone, this use accounts for less than 6 percent of the common uses for this type of material in the United States.
Feb 07, 2011 · It is also growing in popularity as a decorative stone and has a limited use as crushed stone.
