Abstract
The leaching, precipitation and flotation method of recovering metals from ores is simplified by carrying out the leaching and precipitation steps simultaneously in the same reaction vessel. The method is particularly useful for recovering metals from low grade ores. During the leaching and precipitation step, mechanical comminution of the ore is also effected. The preferred reaction vessel is oscillated and the leaching and precipitation process is continuously effected by passage of the materials through the reaction vessel. The method is particularly suitable for recovering copper from oxygen containing copper ores.
