Metal treasures in the deep
Mining of stone and metal has been done since pre-historic times. Ores and metals recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory.
Extraction is complicated: Often, the reserve lays several hundred meters underground elsewise available in open cast mines.
Wilo pumps are ideal for industrial use
When mining the ore at this depth, water – in this case, flowing ground and wastewater – poses a major challenge. Wilo section-type and split case pumps are ideally suited for industrial use with high pressures, such as water removal in underground / opencast mining.
