By definition, open-pit mines are often located in remote areas, and can be large or even gigantic (some mines are much larger than large cities).
The process of operating a mine is complex and involves many industries. The infrastructure (electricity, clean water, wastewater, roads, etc.) is comparable to that of a large city, not to mention the industrial infrastructure itself.
Water is a resource that is used extensively in all areas and its supply is critical. It often comes from far away and is transported by large pipelines.
Chile's open-pit mines are among the largest in the world. Most of them are located in the Atacama Desert in the north of the country, at very high altitudes that can exceed 3,000 metres. Water is transported from the Pacific Ocean over several dozen or even hundreds of kilometres.
Whether in the water pumping stations at the ocean's edge, on the route of the pipelines or, above all, in the mine itself, the water networks are complex, with enormous flows and consequently valves that are to scale (DN1000 to 1200). Often, these valves are manual and, given their size and the torque required, require several thousand turns of the handwheel to open or close them, which represents a very long operating time. We even saw a case where 4 operators took turns for 3 days to open or close a valve!
Most of the time, the feedback from new users of our portable actuators is: "Why didn't we find this sooner!"?
