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.
