Abstract

Способ восстановления металлов и амфигенов из оксидов, при котором применяются горячая зона, примыкающая к шахте, плазмотрон, разогревающий эту зону до необходимой температуры, фурмы в верхней части шахты для выпуска газов и летки в нижней части шахты для выпуска готового продукта, отличающийся тем, что шихта готовится в виде гомогенной смеси ультрадисперсных порошков оксида металла или амфигена с углеродом и под давлением подается в высокотемпературную зону расплава (разложения) оксида, при этом освобождаемый из оксидов кислород связывается с углеродом, образующийся углекислый газ выводится затем из процесса через верхние фурмы и при окислении углерода в процесс вовлекается дополнительное полезное тепло.A method for the recovery of metals and amphigens from oxides, in which a hot zone adjacent to the mine is used, a plasmatron that heats this zone to the required temperature, tuyeres in the upper part of the mine for the release of gases and a taphole in the lower part of the mine for the release of the finished product, characterized in that the charge is prepared in the form of a homogeneous mixture of ultradispersed powders of metal oxide or amphigenes with carbon and is fed under pressure to the high-temperature zone of the oxide melt (decomposition), while the oxygen released from the oxides binds to carbon, the resulting carbon dioxide is then removed from the process through the upper tuyeres and during oxidation additional useful heat is involved in the process.
