Iimfuno ezisisiseko ze izixhobo zokurhangqa isithando somlilo kwizithako:

Izithako ezichanekileyo: Ubunzima bezithako ezingachanekanga bunokukhokelela ngokulula ekulawuleni ukubunjwa kweekhemikhali ezingafanelekanga kwinkqubo yokunyibilikisa okanye ukuphosa okungonelanga kokuphosa, kwaye ixabiso eligqithisileyo linokunyusa ukusetyenziswa. Ukusasazwa okungachanekanga kwamacandelo ekhemikhali ye-ramming material kuya kuzisa ubunzima ekusebenzeni kwe-smelting, kwaye kwiimeko ezinzima kuya kwenza ukuba i-smelting ingenzeki. Ngokubanzi, izithako zisekelwe kuhlobo lwentsimbi enyibilikisiweyo, iimeko zezixhobo, izinto ezikhoyo ezikrwada kunye neendlela ezahlukeneyo zokunyibilikisa.

Ukuchaneka kwezithako kubandakanya imiba emibini: ubunzima be-ramming material kunye nezithako zezithako. Sineminyaka emininzi yamava kwimathiriyeli ye-ramming yesithando somlilo. Thatha i-oxidation yokunyibilika njengomzekelo. Ukuba umxholo wekhabhoni uphezulu kakhulu, uya kwandisa inani le-ore okanye ukwandisa ixesha lokusetyenziswa kwe-oksijini; ukuba umxholo wekhabhoni uphantsi kakhulu, ngokuqinisekileyo uya kunyibilika. Yenza ukwanda kwekhabhoni; ukuba i-S kunye ne-P kwi-ramming material iphezulu kakhulu, iya kuzisa ubunzima ekusebenzeni phambi kwesithando somlilo, esingagcini nje ukwandisa ixesha lokunyibilikisa, kodwa siphinde sigxumeke isithando somlilo ngokunzulu, kwaye ngamanye amaxesha kuphelisa ukunyibilika. Ukuze uthintele le meko ingentla, kubaluleke kakhulu ukwazi ukubunjwa kweekhemikhali zezinto zetsimbi kunye nezixhobo zentsimbi ngaphambi kokubethelwa.
