Metso has introduced an innovative solution, the copper POX (pressure oxidation) leaching process, to extract copper in a ...

According to Still Bright, sulfide ore is first soaked in liquid vanadium, separating the copper from its other elements. Then, the solution is sent through an electrolyzer to collect the pure copper.

The bill targets the mining of sulfide ores, which contain metals like copper and nickel, by extending the state’s ban on mining in the Boundary Waters to the entire Rainy River Watershed.

Rather, these three metals are far more likely to combine with sulfur, so their ores are mostly sulfide minerals. For lead, the primary ore is galena or lead (II) sulfide (PbS). Galena is a ...
