I-Potassium butyl xanthate iyi-reagent entantayo enekhono eliqinile lokuqoqa, esetshenziswa kakhulu ekuntanteni okuxubile kwama-ores ensimbi e-sulfide angeyona ayoni.Lo mkhiqizo ufaneleka ngokukhethekile ukuntanta kwe-chalcopyrite, i-sphalerite, i-pyrite, njll. Ngaphansi kwezimo ezithile, ungasetshenziswa ukuze ukhethe i-copper sulfide ephuma ku-sulfide iron ore, noma ukukhetha i-sphalerite ecushwe yi-copper sulfate ukuze i-flotation.
