Difference between mineral and ore gangue and

Some gangue minerals are difficult to separate, especially when they are finely associated with valuable minerals, or they have similar proprieties like density, floatability, etc. For instance, oxide rare earth minerals have a similar density to oxide iron minerals and are difficult to separate by gravity methods.

Gangue - Wikipedia

Minerals that were once thought of as gangue, and were dumped, may later find a commercial use. When this happens, the old dumps are often reworked to extract the wanted mineral. For example, in copper mines in the 19th century the mineral arsenopyrite was dumped until arsenic became popular as an insecticide later in the century. In the 21st century, the use of gangue has been considered from ...
