Claims (7)

1. Способ получения никеля из отходов, заключающийся в том, что отходы с содержанием никеля от 10% и более и содержанием алюминия от 30% и более расплавляют, подают расплав через форсунку и диспергируют капли расплава в охлаждающем реагенте, подвергают полученный порошок магнитной сепарации для разделения на магнитную и немагнитную фракции, окисляют магнитную фракцию, например, путем обжига, далее смешивают окисленную магнитную фракцию с шлакообразующими компонентами и упомянутым порошком немагнитной фракции и проводят алюминотермическое восстановление никеля.1. The method of producing nickel from waste, which consists in the fact that waste with a nickel content of 10% or more and an aluminum content of 30% or more is melted, the melt is fed through a nozzle and the melt drops are dispersed in a cooling agent, the obtained powder is magnetically separated for separation into magnetic and non-magnetic fractions, oxidize the magnetic fraction, for example, by firing, then mix the oxidized magnetic fraction with slag-forming components and said non-magnetic fraction powder and conduct aluminothermic nickel recovery. 2. Способ по п.1, отличающийся тем, что перед расплавлением отходов их подвергают пиролизу.2. The method according to claim 1, characterized in that before the waste is melted, they are subjected to pyrolysis. 3. Способ по п.1, отличающийся тем, что указанное расплавление отходов проводят в неокисляющей атмосфере.3. The method according to claim 1, characterized in that said melting of the waste is carried out in a non-oxidizing atmosphere. 4. Способ по п.1, отличающийся тем, что указанную диспергацию капель расплава проводят в атмосфере инертного газа.4. The method according to claim 1, characterized in that the dispersion of the droplets of the melt is carried out in an inert gas atmosphere. 5. Способ по п.1, отличающийся тем, что указанную диспергацию капель расплава проводят в воде.5. The method according to claim 1, characterized in that said dispersion of the droplets of the melt is carried out in water. 6. Способ по п.5, отличающийся тем, что указанную магнитную сепарацию полученного порошка проводят в воде, а затем подвергают разделенные порошки обезвоживанию.6. The method according to claim 5, characterized in that the magnetic separation of the obtained powder is carried out in water, and then the separated powders are subjected to dehydration. 7. Способ по п.5, отличающийся тем, что полученные в результате порошки подвергают сушке и затем проводят магнитную сепарацию порошка.7. The method according to claim 5, characterized in that the resulting powders are dried and then magnetic separation of the powder is carried out.
