Hababka birta ah ee dhulka naadir

ere waa laba hab oo guud oo biraha dhulka naadir ah, kuwaas oo kala ah hydrometallurgy iyo pyrometallurgy.

Hydrometallurgy waxaa iska leh habka biraha kiimikada, habka oo dhanna wuxuu ku jiraa inta badan xalka iyo dareeraha.Tusaale ahaan, kala-goynta dhulka naadirka ah ayaa xoogga saaraya, kala-soocidda iyo soo saaristaoksaydhyada dhulka naadir, xeryahooda, iyo hal biraha dhul dhif ah isticmaalaan hababka kala soocidda kiimikada sida roobab, crystallization, oksaydheynta-yaraynta, soo saaridda dareeraha, iyo beddelka ion.Habka ugu badan ee la isticmaalo waa soo saarista dareeraha organic, kaas oo ah habka caalamiga ah ee kala soocida warshadaha ee nadiifinta sare ee hal naadirka ah ee dhulka.Habka hydrometallurgical waa mid adag, nadiifinta alaabaduna waa mid sareysa.Habkani wuxuu leeyahay codsiyo badan oo kala duwan si loo soo saaro alaab la dhammeeyey.

Habka pyrometallurgical waa mid fudud oo leh wax soo saar sare.Dhul naadir ahpyrometallurgy inta badan waxaa ka mid ah diyaarinta alwaaxyada dhifka ah ee dhulka iyadoo la dhimayo silikootermic, biraha dhifka ah ee dhulka ama alloys by electrolysis cusbo dhalaalay, iyo alloys dhulka dhif ah by dhimista kulaylka biraha.Dabeecadda guud ee pyrometallurgy waa wax soo saarka xaaladaha heerkulka sare.
