A recent study, conducted by the Massachusetts Institute of Technology (MIT), examined the potential of recovering critical metals from mine tailings – the waste left behind after ore has been extracted and processed. The study found that mine tailings contain significant amounts of valuable metals, including cobalt, lithium, nickel, and manganese, which are used in the production of batteries, solar panels, and other renewable energy technologies.
The researchers analyzed mine tailings from a variety of sources and found that, on average, they contained approximately 75% of the original content of critical metals. Additionally, they determined that the concentration of these metals was often higher in mine tailings than in the initial ore, making them a potentially viable source of raw materials for the production of renewable energy products.
