On some features of low-temperature mixed crystallization of CsI solutions obtained from industrial wastes
Investigation of multiple low-temperature mixed crystallization (LTMC) of the solution wastes of cesium iodide was reported. LTMC is a very simple and convenient way for an essential decrease of the concentrations of practically all the admixtures including isomorphic ones (Na, K, Rb). However, LTMC...

Investigation of multiple low-temperature mixed crystallization (LTMC) of the solution wastes of cesium iodide was reported. LTMC is a very simple and convenient way for an essential decrease of the concentrations of practically all the admixtures including isomorphic ones (Na, K, Rb). However, LTMC results in CsI enriching with Tl, which enters into the crystallized fraction.
