I-Potassium butyl xanthate yi-reagent ye-flotation enamandla okuqokelela, esetyenziswa ngokubanzi kwi-flotation edibeneyo ye-ores ye-non-ferrous metal sulfide.Le mveliso ifaneleka ngokukhethekileyo kwi-flotation ye-chalcopyrite, i-sphalerite, i-pyrite, njl. Phantsi kweemeko ezithile, ingasetyenziselwa ngokukhethekileyo ukudada kwi-sulfide yobhedu kwi-ore ye-iron sulfide, okanye ukukhetha i-sphalerite eyenziwe nge-copper sulfate ukuze ijikeleze.
