Izinsimbi zomhlaba ezingandileziyizinto ezibalulekile eziluhlaza zokukhiqiza izinto zokugcina ze-hydrogen, i-NDFEB unomphela wezinto zokwenziwa kwezibalo, izinto zokuzikhulisa, njll. Zisetshenziswa kabanzi kwezinsimbi ezingezona izimboni kanye nezimboni zensimbi. Kepha umsebenzi wawo wensimbi uqine kakhulu, futhi kunzima ukuwukhipha ezinhlangeni zawo usebenzisa izindlela ezijwayelekile ngaphansi kwezimo ezijwayelekile. Ekukhiqizweni kwezimboni, izindlela eziphambili ezisetshenzisiwe zingama-electrolysis kasawoti ancibilikisiwe kanye nokwehliswa kwe-thermal ukukhiqiza izinsimbi zomhlaba ezingandile ezivela emhlabathini ezingandile emhlabeni, ama-fluorides, kanye noxisi. I-Ellon Salkerclysis ye-Electrolysis iyindlela eyinhloko yezimboni yokukhiqiza izinsimbi zomhlaba ezihlanganisiwe ezinamaphuzu aphansi ancibilikayo, kanye ne-singleizinsimbi zomhlaba ezingandilena-Ama-alloys omhlaba angavamilenjengeuhlobo linthanum, umrintshi, I-PraseOdDODYIUM, futhineedymium. Inezici zesilinganiso esikhulu sokukhiqiza, asikho isidingo sokunciphisa ama-ejenti, ukukhiqizwa okuqhubekayo, nomnotho wokuqhathanisa kanye nokwenza lula.
Ukukhiqizwa kweizinsimbi zomhlaba ezingandileFuthi ama-alloys nge-molten stleclysis ye-electrolysis ingenziwa ngezinhlelo ezimbili ezibunjiweyo, okungukuthi uhlelo lwe-chloride kanye nohlelo lwe-fluoride oxide. Lowo owayengukuqala unendawo ephansi yokuncibilika, izinto ezingabizi kakhulu eziluhlaza, kanye nokusebenza okulula; Lesi sakamuva sinokwakheka kwe-electrolyte ezinzile, akulula ukumunca umswakama kanye ne-hydrolyze, futhi kunezinkomba ze-electrolysis ephezulu. Kuthathe kancane kancane laba bangaphambili futhi kusetshenziswa kabanzi embonini. Yize amasistimu womabili anezici ezahlukahlukene zenqubo, imithetho yethiyori ye-electrolysis iyavumelana.
Okwesindayoizinsimbi zomhlaba ezingandileNgamaphuzu aphezulu ancibilikayo, kusetshenziselwa indlela yokunciphisa imali yokudlela e-thermal ukukhiqizwa. Le ndlela inesilinganiso esincane sokukhiqiza, ukusebenza kwezikhathi ezithile, kanye nezindleko eziphakeme, kepha ingathola imikhiqizo ebumsulwa ephakeme ngokusebenzisa i-distillation eminingi. Ngokusho kwezinhlobo zokunciphisa ama-ejenti, kunendlela yokunciphisa i-calcium thermal, indlela yokunciphisa i-lithium thermal, iLanthanum (CERIUM
