Barite is not only produced from primary barite deposits, where barite is the primary mineral but there is a growing trend in processing the ores that contain barite in the form of gangue or as the secondary mineral. Deposits having barite is the primary mineral contain barite in a coarsely crystalline form.

Barite is a natural mineral which not only occurs in hydrothermal environments but also forms as unwanted scale, e.g., in the oil and gas industry. Due to its tendency to form solid solutions with other isostructural sulfates, in particular RaSO 4, barite is of environmental and technical relevance.

This can easily be done by scraping a corner of the sample across a streak plate (a piece of unglazed porcelain). The result is that some of the mineral gets ground to a powder and we can get a better impression of its "true" colour (Figure 2.17).
