Potaziyamu butyl xanthate ndi reagent yoyandama yokhala ndi luso lamphamvu lotolera, lomwe limagwiritsidwa ntchito kwambiri pakuyandama kosakanikirana kwamitundu yosiyanasiyana yopanda chitsulo cha sulfide.Mankhwalawa ndi oyenera kuyandama kwa chalcopyrite, sphalerite, pyrite, ndi zina zotero. Pazifukwa zina, angagwiritsidwe ntchito kuyandama mkuwa wa sulfide kuchokera ku sulfide iron ore, kapena kusankha sphalerite yomwe imayendetsedwa ndi mkuwa wa sulfate woyandama.
