Nka kimwe mu byuma bya kera kandi bikoreshwa cyane ku isi, ubutare bw'icyuma ni ibikoresho by'ibanze bikenerwa mu gukora ibyuma n'ibyuma.Kugeza ubu, ubutare bw'amabuye y'agaciro buragenda bugabanuka, burangwa n'umubare munini w'amabuye y'agaciro ugereranije n'amabuye y'agaciro akungahaye, amabuye afitanye isano, hamwe n'ibice bigoye.Ubusanzwe icyuma gikurwa mu bucukuzi bwacyo, kizwi ku izina rya hematite cyangwa magnetite, binyuze mu nzira yitwa amabuye y'agaciro.Intambwe zihariye zigira uruhare mu gucukura ibyuma mu nganda zirashobora gutandukana bitewe n'imiterere y'ubutare n'ibicuruzwa byifuzwa, ariko inzira rusange isanzwe ikubiyemo ibyiciro bikurikira:
Ubucukuzi bw'amabuye y'agaciro
Amabuye y'icyuma abanza kumenyekana binyuze mubikorwa by'ubushakashatsi.Iyo habonetse ububiko bufatika, ubutare buvanwa mu butaka hakoreshejwe tekinoroji yo gucukura nko gucukura cyangwa gucukura amabuye y'agaciro.Iki cyiciro cyambere ningirakamaro kuko gishyiraho urwego rwibikorwa byo gukuramo.
Kumenagura no gusya
Amabuye yakuweho noneho yajanjaguwe mo uduce duto kugirango byoroherezwe gutunganywa.Kumenagura ubusanzwe bikorwa hifashishijwe urusyo cyangwa urusyo rwa cone, kandi gusya bikorwa hakoreshejwe urusyo rusya cyangwa urusyo.Iyi nzira igabanya ubutare kuri poro nziza, byoroshe gutunganya no gutunganya mubyiciro bikurikira.
Gutandukana kwa Magneti
Amabuye y'icyuma akenshi arimo umwanda cyangwa andi mabuye y'agaciro agomba kuvanwaho mbere yuko akoreshwa mu gukora ibyuma n'ibyuma.Gutandukanya Magnetique nuburyo busanzwe bukoreshwa mugutandukanya imyunyu ngugu ya magneti nindi itari magnetique.Imashini zikomeye, nka Huate magnet itandukanya, zikoreshwa mugukurura no gutandukanya ibice byamabuye yicyuma na gangue (ibikoresho bidakenewe).Iyi ntambwe ningirakamaro mugutezimbere ubuziranenge bwamabuye.
Inyungu
Intambwe ikurikiraho ni inyungu zo mu bucukuzi bw'amabuye y'agaciro, aho intego ari iyo kongera ibyuma binyuze mu buhanga butandukanye.Ubu buryo bushobora kuba bukubiyemo gukaraba, kwerekana, hamwe nuburyo bwo gutandukanya imbaraga kugirango ukureho umwanda no kuzamura ubwiza bwamabuye.Inyungu zirashobora kandi gushiramo flotation, aho imiti yongewe kumabuye kugirango ibice byicyuma bireremba kandi bitandukanijwe nibindi bikoresho.
Kureka cyangwa gucumura
Amabuye y'agaciro amaze kugirirwa akamaro, birashobora kuba ngombwa guhuriza hamwe uduce duto duto duto kugirango tunonosore neza.Pelletizing ikubiyemo gukora pellet ntoya mu gutobora ubutare hamwe ninyongeramusaruro nka hekeste, bentonite, cyangwa dolomite.Ku rundi ruhande, gucumura, bikubiyemo gushyushya amande y’amabuye hamwe na flux hamwe n umuyaga wa kokiya kugirango ube misa yahujwe igice kizwi nka sinter.Izi nzira zitegura amabuye yintambwe yanyuma yo kuvoma mugutezimbere imiterere yumubiri no kubiranga.
Gushonga
Intambwe yanyuma mugikorwa cyo kuyikuramo ni ugushonga, aho ubutare bwicyuma bushyushya mu itanura riturika hamwe na kokiya (lisansi ya karubone) na hekeste (ikora nka flux).Ubushyuhe bukabije bumena ubutare mu cyuma gishongeshejwe, cyegeranya hepfo y’itanura, na slag, ireremba hejuru ikavaho.Icyuma gishongeshejwe noneho kijugunywa muburyo butandukanye, nka ingoti cyangwa bilet, hanyuma bigatunganywa kugirango ubone ibicuruzwa byuma nicyuma.
Ni ngombwa kumenya ko ubutare butandukanye bwamabuye y'agaciro hamwe ninganda zitunganya bishobora kugira itandukaniro mubikorwa byihariye bikoreshwa, ariko amahame rusange akomeza kuba umwe.Gukuramo ibyuma mu bucukuzi bw'amabuye y'agaciro ni inzira igoye kandi igizwe n'intambwe nyinshi zisaba gucunga neza umutungo n'ikoranabuhanga.Kwinjizamo ibikoresho bigezweho nka Huate magnet itandukanya byongera imikorere nubwiza bwibikorwa byo gutandukana, byemeza ko ibicuruzwa byanyuma byujuje ubuziranenge busabwa kugirango umusaruro wibyuma nicyuma.
