Mining Ore Concentration

Mineral processing - Wikipedia

There are a number of ways to increase the concentration of the wanted minerals: in any particular case the method chosen will depend on the relative physical and surface chemical properties of the mineral and the gangue. Concentration is defined as the number of moles of a solute in a volume of the solution.

Pre-concentration is the rejection of gangue (barren material) from coarse ore feed. It increases the grade of the ore early in the mining process and avoids feeding the plant with material that will cost more to process than its worth.

Ore - Wikipedia

The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
