Uma insimbi noma ingxubevange isesimweni sayo esiqinile, ukwelashwa kokushisa kubhekisela kunqubo ehlanganisa imisebenzi yokufudumeza nokupholisa. Ukwelashwa kokushisa kusetshenziselwa ukushintsha ukuthamba, ubulukhuni, i-ductility, ukukhululeka kwengcindezi, noma amandla ezibophelelo eziye zathola ukwelashwa kokushisa. Ukwelashwa kokushisa kusetshenziswa kuzo zombili izibophelelo eziqediwe kanye nezintambo noma izinsimbi ezakha izibophelelo ngokuzidonsa ukuze zishintshe ukwakheka kwazo okuncane futhi kube lula ukukhiqizwa.
Uma isetshenziswa ensimbi noma ingxubevange ngenkathi isesesimweni esiqinile, ukwelashwa kokushisa kuhlanganisa izinqubo zokushisa nokupholisa. Lapho usebenzelana nezixhumi eziye zathola ukwelashwa kokushisa, ukwelashwa kokushisa kusetshenziselwa ukukhiqiza izinguquko ekuthambile, ukuqina, i-ductility, ukukhululeka kwengcindezi, noma amandla. Ngaphezu kokushisisa, izintambo noma imigoqo okwenziwa ngazo izibophelelo nazo ziyashisisa ngesikhathi senqubo yokuthungatha ukuze kuguqulwe i-microstructure yazo futhi kube lula ukukhiqizwa.
Amasistimu nemishini yokwelapha okushisayo iza ngezinhlobonhlobo. Izinhlobo ezidume kakhulu zomlilo ezisetshenziswa lapho izibophelelo zokushisa ukushisa ibhande eliqhubekayo, elijikelezayo, nenqwaba. Abantu abasebenzisa imithi yokwelapha ukushisa bafuna izindlela zokonga amandla kanye nokunciphisa izindleko zensiza ngenxa yezindleko eziphezulu zezinsiza zamandla njengogesi negesi yemvelo.
Ukwenza ukuqina kanye nokushisa amagama amabili asetshenziselwa ukuchaza inqubo yokushisa. Kulandela ukucisha (ukupholisa ngokushesha) ngokucwilisa insimbi emafutheni, ukuqina kwenzeka lapho izinsimbi ezithile zishiselwa ezingeni lokushisa elishintsha ukwakheka kwensimbi. Ngaphezulu kuka-850°C izinga lokushisa elincane elidingekayo ukuze kuguqulwe isakhiwo, nakuba leli zinga lokushisa lingashintsha ngokusekelwe enanini lekhabhoni nezinto ezihlanganisiwe ezikhona ensimbi. Ukunciphisa inani le-oxidation ensimbi, umoya wesithando somlilo uyalawulwa.
