Claims (2)

Способ обеднения шлаков, содержащих тяжелые цветные и благородные металлы, продувкой их восстановительными газами, подаваемыми в приэлектродную зону, отличающийся тем, что продувку расплава осуществляют с интенсивностью дутья 0,3-0,9 нм3/т•мин, при одновременном поддержании мощности в агрегате в пределах 350-700 КВт на м2 зеркала ванны агрегата, в котором проводится процесс обеднения, при этом газ вводят в зону расплава не далее 2,5 Дэ от оси электрода и на глубину шлакового расплава в пределах от Нэ до Нэ+0,5Дэ, где Дэ диаметр электрода, а Нэ заглубление электрода в шлаковый расплав.The method of depletion of slag containing heavy non-ferrous and noble metals by blowing them with reducing gases supplied to the near-electrode zone, characterized in that the melt is blown with a blast intensity of 0.3-0.9 nm 3 / t • min, while maintaining power in an aggregate within 350-700 kW per m 2 of the bath mirror of the aggregate in which the depletion process is carried out, while the gas is introduced into the melt zone no further than 2.5 De from the axis of the electrode and to the depth of the slag melt in the range from Ne to Ne + 0, 5De, where Dae is the diameter of the electrode, and Ne is Blenheim electrode into the slag melt. 2. Способ по п.1, отличающийся тем, что восстановительный газ содержит углерод в количестве 0,4-0,6 кг/нм3.2. The method according to claim 1, characterized in that the reducing gas contains carbon in an amount of 0.4-0.6 kg / nm 3 .
