New Technique Developed to Explore Seafloor Mineral DepositsUnderwater Mining Companies Wealth Daily

A new project has been announced to reduce the potential environmental impact of seafloor mining Many deposits were formed by hot springs on the seafloor and the vast majority of these now lie Underwater mining is still in its infancy There are only two underwater mining companies exploring the potential of offshore mining But the current boom in metals may cause the undersea hunt to
