MEJORAS EN METODO PARA TRATAR MINERALES Y CONCENTRALOS DE HIERRO FINAMENTE DIVIDIDOS QUE CONTIENEN METALES NO FERROSOS

Finely-divided iron ores and concentrates which contain non-ferrous metals are roasted and chlorinated in order to vaporize the non-ferrous metals as metal chloride compounds, whereby the finely-divided raw material is oxidized at an elevated temperature to produce an oxide melt, with which a chlori...

Zusammenfassung:Finely-divided iron ores and concentrates which contain non-ferrous metals are roasted and chlorinated in order to vaporize the non-ferrous metals as metal chloride compounds, whereby the finely-divided raw material is oxidized at an elevated temperature to produce an oxide melt, with which a chlorinating reagent and air are mixed in order to vaporize non-ferrous metal chlorides from the iron oxide melt.
