FIELD: metallurgy.
SUBSTANCE: reducing method of metals from oxides refers to reducing technologies of metals from non-organic oxides, at which preparation of homogeneous mixture is performed from ultradisperse powders of metal oxide and carbon, supply of prepared mixture under pressure to high-temperature zone in the well, which is formed with plasmatron jet, decomposition of metal oxide with formation of carbon dioxide that is removed through upper tuyeres of the well, and finished product is removed in the form of ultradisperse metal powder through tap holes in lower part of the well.
EFFECT: method allows reducing power consumption at reduction of metals from oxides and ensures the reduction of content of impurities in finished product at direct extraction of metals from oxides during continuous process.
