The wet grinding circuits in most mills produce pulps of from 40% to 60% solids which are ready for leaching. In a few cases, where grinding is more difficult and the classifiers or cyclones overflow at a more dilute pulp density, it is necessary to thicken ahead of leaching. LEACHING The extraction of uranium from ore is accomplished

The aim was to optimize solubilization so as to enhance bioavailability for the purposes of remediation. The three amendments tested were with citrate, EDTA, and EDDS as chelating agents. The effects of pH, chelator concentration, and leaching time were studied. The most important factor in uranium solubilization was found to be the pH.
