Itsinda rya Technologiste ryaturutse muri UrbanMines ryashimangiye ubushakashatsi ku gukuramo umuringa mu gishishwa cya smelter, gikorerwa sulfate. Sulphating ya slag yakozwe napyritekwibanda cyangwa guhinduranya umurizo ku bushyuhe kuva kuri 500 kugeza 650°C, hamwe na calcine yavuyemo yashizwemo amazi.Ibisubizo byerekanye ko umuringa ntarengwa (70-73%) uboneka muri calcine, ukabonwa na sulfate yamasaha abiri nagatatu kuri 550 o C. Inzira iratoranywa kuko 3-5% byicyuma gusa.Usibye ubushyuhe bwa sulfate, byagaragaye ko ingaruka zikomeye kumuringa zifite umurizo wa pyrite / flotation: igipimo.Ibisubizo byiza byagezweho hifashishijwe sulfate ya 5.00 g hamwe na 2.00 g ya pyrite cyangwa 3.00 g yumurizo.
Guconga umuringa ukoresheje inyongera
Hisha umwuka hanyuma ubishyuhe kugirango ukore icyuma napyritekugera kurwego rwa okiside
