    The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the soughtafter material. In the latter, the extraction of minerals

    Waste arising from mining is called gangue. Both surface and underground mining often require large quantities of rock to be broken away to reach the ore. Gangue is usually placed in heaps near the mine. Many Swedish mines use parts of the gangue as a resource, e.g. as aggregate for road construction or to refill mined
