Ubumenyi rusange kubyerekeye amanota
Urwego rwamabuye yerekana ibikubiye mubintu byingirakamaro mu bucukuzi.Mubisanzwe bigaragarira mubice rusange (%).Bitewe nubwoko butandukanye bwamabuye y'agaciro, uburyo bwo kwerekana urwego rwamabuye nayo aratandukanye.Amabuye y'agaciro menshi, nk'icyuma, umuringa, isasu, zinc n'andi mabuye y'agaciro, bigaragazwa nijanisha ryinshi ryibigize ibyuma;urwego rw'amabuye y'agaciro amwe agaragazwa nijanisha ryinshi rya oxyde, nka WO3, V2O5, nibindi;Urwego rwibikoresho byinshi bitarimo ubutare bigaragazwa nijanisha ryinshi ryamabuye y'agaciro cyangwa ibimera, nka mika, asibesitosi, potas, alunite, nibindi.;urwego rw'ibyuma by'agaciro (nka zahabu, platine) amabuye agaragara muri g / t; Urwego rw'amabuye y'agaciro ya diyama agaragara muri mt / t (cyangwa karat / toni, yanditswe nka ct / t);urwego rwamabuye ya plaque rusanzwe rugaragara muri garama kuri santimetero kibe cyangwa kilo kuri metero kibe.
Gusaba agaciro k'amabuye bifitanye isano rya bugufi n'urwego rwayo.Amabuye y'agaciro arashobora kugabanywamo amabuye akungahaye hamwe n'ubutare bukennye ukurikije amanota.Kurugero, niba ubutare bwicyuma bufite urwego rurenga 50%, byitwa ubutare bukize, kandi niba urwego ruri hafi 30%, rwitwa ubutare bubi.Mubihe bimwe bya tekiniki nubukungu, urwego rwinganda zamabuye y'agaciro akwiye gucukurwa mubisanzwe, ni ukuvuga urwego ruto rwinganda.Amabwiriza yayo afitanye isano rya hafi nubunini bwabitswe, ubwoko bwamabuye, gukoresha neza, gushonga no gutunganya ikoranabuhanga, nibindi. Urugero, ubutare bwumuringa bushobora gucukurwa iyo bugeze kuri 5% cyangwa munsi yayo, naho zahabu yimitsi igera kuri garama 1 kugeza kuri 5 / ton.
Urwego rw'inganda bivuga ibikoresho by'ingirakamaro bifite inyungu mu bukungu (birashobora nibura kwemeza ko byishyurwa amafaranga atandukanye nko gucukura amabuye y'agaciro, ubwikorezi, gutunganya no gukoresha) mu gice runaka cy’ibigega by’amabuye y'agaciro mu mushinga umwe (nko gucukura cyangwa gucukura. ).Ikigereranyo cyo hasi cyane cyibigize.Ikoreshwa mukumenya urwego rushobora kugarurwa mubukungu cyangwa urwego rwubukungu buringaniye, ni ukuvuga urwego mugihe agaciro kinjiza amafaranga yubucukuzi bwacukuwe angana namafaranga yose yinjira kandi inyungu yubucukuzi ni zeru.Urwego rwinganda ruhora ruhinduka hamwe niterambere ryubukungu nubuhanga hamwe nurwego rusabwa.Kurugero, kuva mu kinyejana cya 19 kugeza ubu (2011), urwego rwinganda rwamabuye yumuringa rwaragabanutse ruva kuri 10% rugera kuri 0.3%, ndetse n’urwego rw’inganda rwa bimwe mu bubiko bunini bw'umuringa rushobora kugabanuka kugera kuri 0. 2%.Byongeye kandi, amanota yinganda afite amahame atandukanye kubwoko butandukanye bwamabuye y'agaciro.
