Abstract:Dealing with thallium-bearing materials by vacuum distillation under the condition of 400~700°Cand 10-60 Pa.Measured contents of Cd,Tl and Pb under these temperatures.Analzed relations between evaporation rate,residue duty of Cd with temperatures, and The relyations that between evaporation rate,evaporative duty of Tl and Pb with temperatures.Least square method is used to fit the relations and got that the most suitable temperature for evaporating Cd is 560°C;Analyzed the relations between the activity coefficients ratio of Cd-Tl system and Cd-Pb system and temperatures as well as mole fractions,also got fitted equations of them;Analyzed the relation between gas-liquid cotents of Cd-Tl,Cd-Pb systems and temperatures.It is valuable for extracting Tl,Pb with vacuum distillation.
