Ƙwararrun masana fasaha daga UrbanMines sun jaddada nazarin hakar tagulla daga smelter slag, wanda aka yiwa sulphating. Sulphating na slag da aka yipyritemai da hankali ko wutsiyar ruwa a yanayin zafi daga 500 zuwa 650°C, kuma sakamakon calcine an zubar da ruwa.Sakamakon ya nuna cewa ana samun matsakaicin leaching jan ƙarfe (70-73%) daga calcine, wanda aka samu ta hanyar sulfate na sa'o'i biyu da uku a 550 o C. Tsarin yana zaɓi tunda kawai 3-5% na baƙin ƙarfe yana leaching.Bugu da ƙari ga zafin jiki na sulphating, an gano cewa babban tasiri akan leaching jan ƙarfe yana da pyrite / flotation tailings: rabo.An sami sakamako mafi kyau ta hanyar sulphating na 5.00 g slag tare da 2.00 g na pyrite ko 3.00 g na wutsiya.
