For instance https://en.wikipedia.org/wiki/Kennecott_Utah_Copper https://en.wikipedia.org/wiki/Kennecott_Utah_Copper is sort of famous for coming into existence along with new techniques to extract copper from low density ores. They’re dismantling an entire mountain to produce 1% of the world’s copper. The word cobalt does not appear on this page. However I found a news article from about 18 months ago stating Rio Tinto, who apparently own that mine, signed an MOU with another company to explore recovering cobalt and bismuth, by experimenting on this mine. Which I take to mean is possible but not being done at present. But in a January update they mention bismuth experiments but not cobalt: https://www.fortuneminerals.com/news/press-releases/press-release-details/2025/Fortune-Minerals-Provides-an-Update-of-NICO-Project-Test-Work-Rio-Tinto-Process-Collaboration--Feasibility-Study/default.aspx https://www.fortuneminerals.com/news/press-releases/press-re...
