Gangue Wikipedia

The separation of mineral from gangue is known as mineral processing, mineral dressing, or ore dressing.It is a necessary, and often significant, aspect of mining.It can be a complicated process, depending on the nature of the minerals involved. For example, galena, an ore of lead, is usually found in large pieces within its gangue, so it does not normally need extensive processing to remove
