Many of the detector models can function underwater and are fully waterproof. On the other hand, mine detectors are not waterproof and cannot work underwater. 9. Regular devices are able to work effectively in mineralized soil as well. Mineralized soil, though, throws off a mine detector and renders it nearly useless.
Today, satellites are used by major mining companies for exploration of minerals – BHP Billiton, Newmont Mining and Anglo American are just a few to do so. "UPP allows us to gather, organise, fuse, process and analyze vast amounts of data quickly." The key of using satellites for mineral discovery is resonance coupling, a natural …
