Researchers studied a special bacterium found in rare earth mining tailings that can remove harmful cadmium and reduce sulfate contamination. By optimizing growing conditions like temperature, pH, and food sources, they found the bacterium could remove over 95% of cadmium and reduce sulfate levels significantly. This discovery offers a promising environmentally-friendly method to clean up contaminated mining sites.
