Mine Waste Transfer and Disposal Methods - Mine

The separation of minerals from gangue is called mineral processing. Oftentimes, inefficient processing methods can produce gangue that still holds an ample amount of valuable minerals. As values of minerals increase, it can even be profitable to reprocess gangue to extract additional minerals that may have been missed during the first processing.

Understanding Mining Waste Management and

2020-5-21  The separation of the mineral from the gangue is known as mineral processing. The gangue needs to be reprocessed a few times to extract all the minerals from it as some amounts of minerals may be missed during the first processing. Mine Tailings; These are finely ground rocks and mineral waste that is a result of mineral processing.
