PROCESSO PARA A FUNDICAO DE METAIS A PARTIR DE MINERIOS OU CONCENTRADOS DE METAIS NAO FERROSOS SULFIDICOS,OXIDIOS E/OU FINAMENTE GRANULADOS,BEM COMO CONJUNTO PARA A CONCRETIZACAO DESSE PROCESSO

摘要

In the smelting process of recovering metal from non-ferrous metal oxide ores or concentrates and/or from fine-grained non-ferrous metal sulfide ores or concentrates, particularly from non-ferrous heavy metal sulfide ores or concentrates, any sulfide ores are initially oxidized. The ores or concentrates are then supplied to a fluidized bed of coal in a melting gasifier (1). A certain particle size is maintained. Sulfide ores are supplied to a melting burner (2), which directs a flame jet into the fluidized bed of coal (FIG. 1).
