I-copper slag ngokuvamile imnyama noma insundu, ingaphezulu linokukhanya kwensimbi, isakhiwo sangaphakathi ngokuyisisekelo siyi-vitreous, isakhiwo siminyene, siqinile futhi siyaphuka, kanti ukwakheka kwamakhemikhali kuyinkimbinkimbi kakhulu. Kusukela kokuqukethwe kwethusi kokunye ore elibi le-copper (Cu <1%), okunye ku-ore yethusi ephakathi nendawo (Cu1 ~ 2%), okunye ku-copper-rich (Cu> 2%) uhla, FeSi02, CaO , Okuqukethwe kwe-AL203 kuphakeme, kubalwa ngaphezu kwe-60% ye-slag, ingxenye enkulu yokwakheka kwamaminerali e-iron peridotite, elandelwa yi-magnetite, kunenombolo encane yemithanjeni eyakhiwe umzimba we-vitreous.
U-Xiye usethuthuke futhi wakwazi kahle ubuchwepheshe bokwelashwa kwe-copper tailing slag ngendlela ye-electrothermal, evikela imvelo, iphinde isebenzise imfucuza eqinile futhi iguqule imfucuza ibe umcebo.
Ubuchwepheshe benqubo bamukela isithando somlilo esikhethekile sikagesi esakhiwe ngu-Xiye ngokuzimela, futhi samukela inqubo ekhethekile yokushaja, ngokuqaphela ngempumelelo ubuchwepheshe bokwelapha i-copper tailing slag ngesithando somlilo sokuqala sikagesi e-China.
