Ore Blending - Metallurgist & Mineral Processing Engineer

About ore blending & stockpiles: Since the function of the stockpile is to act as an ore reservoir rather than as an ore processor, the action of forming a stockpile should have as little effect as possible on the material. Several undesirable effects are produced by discharging the material from too great a height above the stockpile.
