Ngesonto eledlule, intengo yemakethe yezinto zokusetshenziswa zasekhaya zezinhlobo eziningi iyaqhubeka nokwehla, futhi ukwehla kukhulu. Esidingweni esiphansi sezinto zokusetshenziswa eziqediwe sehlulekile ukukhishwa ngempumelelo, kulindeleke ukuthi imakethe yehlise isimo, ukuncipha kokugcinwa kokukhiqizwa kwensimbi kukhuphuke kakhulu, ukwakheka kwengcindezi ethile emakethe yezinto zokusetshenziswa. Amanani ensimbi aqhubeke nokwehla kakhulu ngesonto eledlule; ukwehla kwentengo ye-coke yensimbi; Amanani amalahle e-coking azinzile ekwindla; ukwehla kwentengo yezinhlobo eziphambili ze-Ferroalloy. Phakathi nalesi sikhathi, izinguquko zentengo zezinhlobo ezinkulu zimi kanje:
