Verfahren zum Trennen der Buntmetallmineralien aus sulfidischen Erzen
Uni aus sulfidischen, Erzen die Bumtrpetallmine-c-alien (Klei-, Zink-, Kupfermineralien u. a.) von<lern Eisen zu trennen, werden die s.ulfidischenErze nach dein 1Zösten Rotiert.Zweckmäßig ist es, die sulfidischen Erze zu-nächst so weit zu rösten, daß das Eisensulfid oxy-diert wird, während die Buntmetallsulfide ihreFlotationsfäliigk.eit Behalten. Schließlich wird dasErz nach (lern Rösten der Flotation ausgesetzt, wo-bei die liuntinetallstilfide von den sie hegleiterndenStoffen getrennt werden, indem sich die Bunt-inetallstiltide inn Flotationsschaum sammeln.Process for separating non-ferrous metal minerals from sulfidic ores Uni from sulfidic ores the Bumtrpetallmine- c-alien (clay, zinc, copper minerals, etc.) from <learn to separate iron, the s.ulfidischen Ore after your 1zösten rotates. It is useful to add the sulphidic ores next to roast so far that the iron sulfide is oxy- is dated, while the non-ferrous metal sulfides their Flotation ability to be retained.
