This Colorado town wants to mine gold from waste
Briefly

The proposal by CJK Milling aims to reprocess decades-old mine waste in Leadville to extract valuable metals, facilitating cleanup and promoting a 'circular economy' in mining.
Every minute, 694 gallons of contaminated mine water flow from Leadville's Superfund site, highlighting the ongoing environmental pollution issues linked to historic mining activities.
CJK Milling's initiative illustrates a growing global trend towards remining waste materials, aligning with broader goals of economic sustainability in the mining industry.
Backers of the Leadville project argue that remining the waste would expedite the long-delayed cleanup efforts, offering a dual benefit of resource recovery and environmental remediation.
