The storage of ore in preparation for the smelting or dressing process, or for the shipment of concentrate, or the storage of ore. The purpose of storage is to ensure quantitative stability for supply or shipment, but it can also be for the purpose of blending ores of different qualities, or for the homogenization of raw materials that vary in quality. There are two ways to store ore: in an open or roofed yard, or in a pit dug into the ground or enclosed area (yard), or in one or more large cylindrical or rectangular containers.
