The Mineral quartz. Quartz is one of the most well-known minerals on earth. It occurs in basically all mineral environment s, and is the important constituent of many rock s. Quartz is also the most varied of all minerals, occurring in all different forms, habits, and colors. There are more variety names given to Quartz than any other mineral.

Silicates are the primary gangue minerals (quartz, feldspar, albite, mica, etc.) in most copper deposits. Processing such multimineral ores to produce individual mineral(s) of the desired quality is extremely tough. The challenges during beneficiation become manifold if it contains a higher amount of impurities.
