ere inzira mbiri dzakajairwa dzerare Earth metallurgy, dzinoti hydrometallurgy uye pyrometallurgy.
Hydrometallurgy ndeyemakemikari metallurgy nzira, uye maitiro ese ari kunyanya mukugadzirisa uye kunyungudutsa.Semuenzaniso, kuparara kwepasi risingawanzo kutarisisa, kupatsanurwa uye kutorwa kwezvisingawanzo pasi oxides, makomisheni, uye imwe isingawanzo simbi yepasi inoshandisa makemikari ekuparadzanisa maitiro akadai sekunaya, crystallization, oxidation-kuderedza, kunyungudutsa, uye ion exchange.Nzira inonyanya kushandiswa ndeye organic solvent extraction, inova nzira yepasirese yekuparadzanisa kwemaindasitiri kwepamusoro-kuchena imwechete isingawanzo pasi zvinhu.Iyo hydrometallurgical process yakaoma, uye kuchena kwechigadzirwa kwakakwira.Iyi nzira ine huwandu hwakawanda hwekushandisa mukugadzira zvigadzirwa zvakapedzwa.
Iyo pyrometallurgical process iri nyore uye ine yakakwira chibereko.Rare pasipyrometallurgy inonyanya kusanganisira kugadzirwa kweasingawanzo pasi alloys ne silicothermic kuderedzwa, isingawanzo simbi yepasi kana alloys neyakanyungudutswa munyu electrolysis, uye isingawanzo pasi alloys nesimbi yekupisa kupisa.Chimiro chakajairika che pyrometallurgy kugadzirwa pasi pemamiriro ekushisa akanyanya.
