What is Immobilizing Heavy Metals in Mining Waste about?

This document discusses immobilizing heavy metals from mining waste. Specifically, it examines using wood ash to treat copper flotation tailings from an old copper mine in Serbia. Laboratory leaching tests showed that mixing the tailings with wood ash at a 1.0:0.5 ratio drastically reduced the mobility of toxic metals in the waste and increased the pH of leachates from 3.38 to 6.66. This demonstrates that wood ash can effectively immobilize toxic metals and stabilize mine waste. Using a low-cost treatment a
