Melting of oxidized nickel ores in a barbotage unit: I ...

The possibility of effective processing of oxidized nickel ores (ONOs) to form ferronickel in a barbotage unit (Vanyukov furnace for liquid bath melting (LBM)) is theoretically corroborated. The heat balances of the LBM processing of unreduced ONOs or the cinder preliminarily reduced in tubular kilns to form ferronickel are calculated.
