The inadequate management of waste from the mining industry can lead to several environmental problems. For instance, the extraction of quartzite, an ornamental stone, generates quartzite waste (or residues or tailings) (QTZ), which is commonly deposited in the environment, causing landscape degradation, contamination by dust, and silting of rivers. To …

Quartzite begins as quartz-rich sandstone, typically composed of about 90-99% quartz grains. Under intense heat (typically between 200°C to 700°C) and pressure, the sandstone undergoes recrystallization. This process fuses the quartz grains together, eliminating porosity and significantly increasing the rock's hardness and durability.

The transition of sandstone into quartzite is a gradual process. A single rock unit such as the Tuscarora Sandstone of the central Appalachians might fully fit the definition of quartzite in the parts of its extent where its quartz grains have been metamorphosed into a durable interlocking mass. It would be better called "sandstone" in other areas.
