Description
Изобретение относитс к области цветной металлургии, в частности к способам рафинировани кадми .The invention relates to the field of non-ferrous metallurgy, in particular to methods for refining cadmium.
Известен способ рафинировани кадми вакуумной дистилл цией при 450°С, при котором степень очистки от цинка составл ет 91,5%.A known method of refining cadmium by vacuum distillation at 450 ° C, in which the degree of purification from zinc is 91.5%.
Предложенный способ отличаетс тем, что в расплав кадми :перед вакуумироваиием ввод т никель в количестве 1-8 вес. ч. на 1 вес. ч. цинка, а вакуумную дистилл цию ведут ;при 450-600°С. Это повышает степень очистки до 99,8%.The proposed method is characterized in that cadmium melt: before evacuation, nickel is introduced in an amount of 1-8 wt. h. on 1 weight. including zinc, and vacuum distillation is carried out at 450-600 ° C. This increases the degree of purification to 99.8%.
Способ осуществл ют следующим образом.The method is carried out as follows.
Иеред рафинированием в расплавленный кадмий тавод т металлический никель и выдерживают до нолного его растворени . Затем кадмиевый расплав подвергают вакуумной дистилл ции, котора обеспечивает получение марочного кадми .It is refined into molten cadmium metal and nickel metal and is allowed to dissolve to the fullest extent. Then the cadmium melt is subjected to vacuum distillation, which provides branded cadmium.
При таком способе цинк переходит в остаток , который при 420-600°С находитс в твердом виде.With this method, zinc passes into the residue, which at 420-600 ° C is in solid form.
В лабораторных услови х был Проведен способ рафинировани кадми от цинка вакуумной дистилл цией с ттрисадкой никел в кадмиевую ванну.Under laboratory conditions, a cadmium refining process from zinc by vacuum distillation with nickel trisodium was carried out in a cadmium bath.
Результаты опытов представлены в таблице .The results of the experiments are presented in the table.
Из данных таблицы видно, что введение никел в кадмий перед дистилл цией обеспечивает снижение содержани цинка в кадмиевом конденсате нронорционально количеству введенного никел . Способ прост в исиолнении и требует незиачительного увеличени затрат .From the data in the table it can be seen that the introduction of nickel into cadmium before distillation ensures a decrease in the zinc content in the cadmium condensate, which is normal to the amount of nickel introduced. The method is simple to implement and requires a costly increase.
Предмет изобретени Subject invention
Способ рафинировани кадми вакуумной дистилл цией, отличающийс тем, что, с целью увеличени степени очистки от цинка.A method of refining cadmium by vacuum distillation, characterized in that, in order to increase the degree of purification from zinc.
20 в расплав кадми перед еакуумированием ввод т никель в количестве 1-8 вес. ч. на 1 вес. ч. цинка, а вакуумную дистилл цию ведут при температуре 450-600°С.20 Nickel is introduced into the cadmium melt before evacuation in the amount of 1-8 wt. h. on 1 weight. including zinc, and vacuum distillation is carried out at a temperature of 450-600 ° C.
