ʻO ka potassium butyl xanthate he mea hoʻoheheʻe flotation me ka hiki ke hōʻiliʻili ikaika, i hoʻohana nui ʻia i ka flotation hui ʻana o nā ʻano mea ʻole ferrous metala sulfide.He kūpono loa kēia huahana no ka lele ʻana o ka chalcopyrite, sphalerite, pyrite, etc. Ma lalo o nā kūlana kikoʻī, hiki ke hoʻohana ʻia i ka flotation copper sulfide mai ka sulfide iron ore, a i ʻole e koho i ka sphalerite i hoʻāla ʻia e ke keleawe sulfate no ka lele.
