Claims (1)

Электродуговой способ получения олова высокой чистоты из касситеритового концентрата, включающий расплавление однофазной электрической дугой прямого действия (род тока переменный) окатышей касситерита со шлакообразующими добавками в графитовом тигле или кристаллизаторе, наведение шлаковой ванны, засыпку зеркала ванны молотым графитом, перевод процесса в электролитический режим, проведение восстановления олова в шлаковом расплаве пропусканием электрического тока, осаждение жидкого олова на дно тигля, отличающийся тем, что при переходе на электролитическое восстановление род тока не изменяют, чего достигают простым замыканием верхнего электрода на графитовый слой.An electric arc method for producing high-purity tin from cassiterite concentrate, including melting a direct-acting single-phase electric arc (alternating current type) cassiterite pellets with slag-forming additives in a graphite crucible or crystallizer, inducing a slag bath, filling the bath mirror with ground graphite, putting the process into electrolytic mode, reduction of tin in the slag melt by passing an electric current, the deposition of liquid tin to the bottom of the crucible, characterized in that when ode for electrolytic reduction type of current do not change, which is achieved simply by closing the upper electrode to a graphite layer.
