Ikoranabuhanga ry’imashini zikora ibyuma by’agaciro ni uburyo bwo gushyushya no gushongesha ibikoresho by’icyuma by’agaciro nka zahabu, ifeza, platine, palladium, nibindi, mu buryo bw’amazi hanyuma ukabisuka mu bibumbano cyangwa mu bundi buryo kugira ngo ukore ibintu bitandukanye. Iri koranabuhanga rikoreshwa cyane mu gukora imitako, gucura ibiceri, gukora amenyo no mu nganda.
Hari ubwoko butandukanye bw'imashini zikoreshwa mu gucura zishobora gukoreshwa muri iki gikorwa. Izikoreshwa cyane zirimo:
1. Imashini zicukura zikoresheje centrifugal: Izi mashini zikoresha imbaraga zikoresha centrifugal kugira ngo zitere icyuma gishongeshejwe mu ishusho wifuza zigizungurutsa ku muvuduko mwinshi mu gihe zigisuka mu ibumba.
2. Imashini zikoresha imashini zikoresha imashini zisukura umwuka: Izi mashini zikura umwuka mu ibumba mbere yo kuwuzuzamo icyuma gishongeshejwe n'umuvuduko wa imashini zisukura umwuka kugira ngo zigire irangi ryiza ridafite utubuto tw'umwuka cyangwa imyanda.
3. Amatanura yo gushonga: Aya matanura akoresha induction ya electromagnetic kugira ngo ashyushye kandi ashongeshe ibikoresho by'icyuma biri mu gikoresho mbere yo gusukwa mu bimera cyangwa mu bindi bishushanyo.
4. Imashini zicukura umuriro w'amashanyarazi (EAF): Ubu bwoko bw'imashini bukoresha umurongo w'amashanyarazi hagati y'amashanyarazi abiri asohora ubushyuhe bwinshi bushongesha ibikoresho fatizo nk'ibyuma bisigaye cyangwa alloys vuba bihagije kugira ngo bikore ingufu nyinshi zikoreshwa gake ugereranije n'izindi nk'amatanura akoresha gazi.
Muri rusange, ikoranabuhanga ry’imashini zikora ibyuma by’agaciro rifite uruhare runini mu gukora imitako myiza mu gihe rigabanya imyanda no kongera umusaruro. Bisaba abatekinisiye b’abahanga basobanukiwe uburyo izi mashini zikora hamwe n’ingamba z’umutekano zikenewe kugira ngo zikoreshwe neza kugira ngo hirindwe impanuka zishobora kubaho mu gihe cy’ibikorwa birimo ahantu hashyuha cyane hashobora kubaho ibyago by’inkongi z’umuriro mu gihe ingamba z’umutekano zidafashwe nk’ingenzi.
