Why Mineral Processing is Very Important for the
If the valuable minerals within the ore cannot be recovered separately from the gangue material, the resource is not an ore in the first place. For example, most copper deposits have a grade of less than 1% Cu, which is very low. The ore value without processing could justify its mining, but usually, it doesn’t, especially for underground mining.
