Ukumbiwa kwezimayini kubandakanya ukukhipha amaminerali abalulekile noma izinto zokwakha zezwe, okuhlanganisa ukuhlola, ukumba, ukucutshungulwa, kanye nokuthuthwa kwempahla. Ukuncibilika kwensimbi, okuyingxenye ebalulekile yezimayini, kuyinqubo yokukhipha izinsimbi ezifana nensimbi, ithusi, ne-aluminium ensimbini.
Izinyathelo ezijwayelekile zokuncibilikisa insimbi zihlanganisa:
Imayini: Ukuthola ama-ore aqukethe izinsimbi ezifunwayo emhlabeni.
Ukuchotshozwa nokugaya: Ukuhlukanisa insimbi ibe yizinhlayiya ezincane ukuze uthole indawo engcono.
Ukugxila: Ukwehlukanisa amaminerali abalulekile nemfucumfucu (gangue).
Ukuncibilika: Ukushisisa insimbi egxilile esithandweni emazingeni okushisa aphezulu ukuze kukhishwe insimbi ngokukhipha ukungcola.
Ukucwenga: Izinqubo ezengeziwe zokuhlanza ukuze kuzuzwe ubumsulwa bensimbi obufunekayo.
Ukumba izimayini nokuncibilikisa kunomthelela omkhulu kwezemvelo ngenxa yezinqubo zokumba, ukukhiqizwa kwemfucuza, ukudedelwa kokungcola, nokushintshwa kwezindawo. Imizamo iyaqhubeka yokunciphisa le mithelela ngobuchwepheshe nokuhambisana nemithethonqubo yezemvelo.
Izimayini nokuncibilikisa insimbi kuhlanganisa: I-electrodeposited titanium electrode ye-cobalt,I-electrodeposited titanium electrode ye-zinc,electrodeposited titanium electrode yethusi,I-electrodeposited titanium electrode ye-nickel-cobalt.
