    Beneficiating Copper Oxide Ores . Except in unusual circumstances, copper ores must be beneficiated prior to smelting. In leaching however, ores are often processed without prior beneficiation, andCopper Hatch Consulting engineering and project,All over the world, high-grade copper deposits are rare; low-grade ore bodies are common. Beneficiating these low-grade resources is expensive. Productive mines and concentrators cost billions of dollars to capitalize, and many years to develop. Today, costs are increasing for both open-pit and underground operations.
