Kwiveki ephelileyo, ixabiso lemarike yezinto ezikrwada zasekhaya kwiintlobo ngeentlobo liyaqhubeka nokuhla, kwaye ukuhla kukhulu. Kwimfuno ephantsi yezinto ezigqityiweyo ayiphumelelanga ukukhupha ngokufanelekileyo, kulindeleke ukuba imakethi yehlise imeko, ukuncipha kwemveliso yentsimbi kunyuke kakhulu, ukwakheka koxinzelelo oluthile kwimarike yezinto ezikrwada. Amaxabiso e-iron ore aqhubeke nokuhla kakhulu kwiveki ephelileyo; Ukuhla kwexabiso le-coke ye-Metallurgical iyonke; Amaxabiso amalahle e-coking azinzile ekwindla; Ukuhla kwexabiso leentlobo eziphambili ze-Ferroalloy iyonke. Ngeli xesha, utshintsho lwamaxabiso kwiintlobo eziphambili zezi zilandelayo:

Amaxabiso eentsimbi ezithengwe kwamanye amazwe ehle kakhulu
