  1. POSTOPEK ZA EKSTRAKCIJO PROIZVODOV, KI SO INDUSTRIJSKO ZANIMIVI, LOČENI DRUG OD DRUGEGA, IZ BOKSITA ALI RDEČEGA BLATA, KI NASTANE PRI PREDELAVI BOKSITA PATENTNI ZAHTEVKI
    1. Postopek za ekstrakcijo proizvodov, ki so industrijsko zanimivi, ločeni drug od drugega, iz boksita ali rdečega blata, ki nastane pri procesiranju boksita, omenjeni postopek vsebuje sledeče korake: - opcijsko mletje in/ali sušenje materiala za obdelavo pri temperaturo od 60 do 250°C; - opcijsko praženje posušenega materiala; - taljenje pridobljenega materiala - vzdrževanje talilne kopeli pri temperaturi, ki je višja od 1350°C; - znotraj talilne kopeli razpihovanje klora, ali vsaj in situ sestavka, ki generira klor, po možnosti skupaj z vsaj inertnim plinom; - opcijsko mešanje staljene kopeli, da se favorizira razprševanje klora in kinetika reakcij pri postopku; - zbiranje plinskega toka, ki zapušča talilno kopel in pošiljanje le-tega, vzdržujoč temperaturo nad 1500°C, v kontrolirani hladilni sistem; - kontrolirano hlajenje plinskega toka s selektivno kondenzacijo kloridov različnih elementov, ki so industrijsko zanimivi, kot na primer natrijev klorid, železov (III) klorid, galijev (III) klorid, aluminijev klorid, titanov (IV) klorid, silicijev (IV) klorid; - ločeno zbiranje posameznih kloridov; - opcijsko nadaljnje prečiščevanje vsakega od zbranih kloridov s frakcijsko destilacijo.
