CESIUM
taining cesium from its ore, such as acid leaching, basic fusion followed by water leaching, and the direct reduction of the ore. The most widely used is the acid leaching process, although direct reduction of the ore shows considerable promise. The basic fusion processes are technically feasible, but have not been reported as extensively.
