##### US5169503A - Process for extracting metal values

Metal values are solubilized from ore by a lixiviant having a pH from 5 to 8, comprising an aqueous solution of a chloride salt and a hypochlorite salt. Cyanuric acid may be added to retard decomposition of the lixiviant. In one alternative embodiment, any remaining hypochlorite ions are then eliminated by adding hydrogen peroxide or a reducing agent to the pregnant lixiviant.
