As imashini z'imitako ya zahabuuruganda rukora imitako ya zahabu, dusangira ubumenyi ku bakiriya bacu.

Zahabu ivangwa n'ibyuma nk'umuringa n'ifeza iyo ikoreshwa mu gukora imitako. Zahabu y'umweru si ikintu ubwacyo, ahubwo ni zahabu ivanze n'ibindi byuma kugira ngo ikore isura ya feza. Ibyuma bikunze gukoreshwa muri zahabu y'umweru ni nikeli na paladiyamu, cyangwa se zinki cyangwa tini.

IVANGA RY'IBIKORESHO BYO GUKORA IMIRIMBO

Uzi ibyuma wambaye?

Ushobora gutungurwa no kumenya ingano y'ibyuma bitandukanye n'aloyi byagiye byinjira mu mitako yawe no mu mubiri wawe. Muri William Rowland twishimiye gutanga ibyuma n'aloyi bifite isuku nyinshi ku nganda zitandukanye ku isi.

Ubwoko bw'ingenzi bw'ibyuma dutekerezaho iyo tugeze ku gukora imitako ni ifeza na zahabu, ariko mu by'ukuri imitako myinshi ntabwo ikorwa mu ifeza cyangwa zahabu. Impamvu ni uko mu miterere yayo myiza cyane, ifeza na zahabu byombi byoroshye cyane ku buryo bitaba bikwiriye imitako myinshi. Ibyuma byose bifite imiterere yihariye ituma bikwiranye n'imirimo runaka, niyo mpamvu ari ngombwa kuvugana n'umucuruzi w'ibyuma w'inararibonye mu gihe utumiza.

Ubwoko bw'ifeza busukuye cyane bwitwa 'ifeza nziza' kandi iyi ikoreshwa cyane cyane mu gukora bullion, aho gukoresha imitako cyangwa amafaranga, kuko yoroshye cyane. Silver nayo ishobora kwangirika cyane, kandi kuvanga n'ibindi byuma bishobora kuyirinda. Ahubwo, hakoreshwa ifeza ikoze mu cyuma cya aluminium. Iyi ifite ubuziranenge bwa 92.5%, ariko isigaye ivanze n'ibindi byuma nka umuringa, zinc cyangwa silicon.

Mu buryo nk'ubwo, zahabu mu buryo bwayo busanzwe ikoreshwa mu gukora imitako, kuko yoroshye kandi ishobora guhinduka nabi mu mitako cyangwa amafaranga. Zahabu ivangwa n'ibyuma nka umuringa n'ifeza iyo ikoreshejwe mu gukora imitako. Zahabu y'umweru si ikintu ubwacyo, ahubwo ni zahabu ivanze n'ibindi byuma kugira ngo ikore isura ya feza. Ibyuma bikunze gukoreshwa muri zahabu y'umweru ni nikeli na paladiyamu, cyangwa se zinki cyangwa tini.

Hariho kandi uruvange rw'izahabu rutandukanye kugira ngo hakorwe amabara n'ingaruka zitandukanye. Izahabu y'iroza ni uruvange rw'izahabu y'umuhondo, ifeza n'umuringa, kugira ngo hakorwe ibara ry'umutuku, kandi hahora havumburwa uruvange rushya rw'ibyuma bikoreshwa mu gukora imitako.

Muri Hasung tuzi ibyuma kandi kuva mu 2000, dufite ubumenyi bwihariye ku miterere yabyo n'uburyo bikoreshwa mu bikorwa bitandukanye. Iyo uguze ibyuma ku isoko, haba mu gutumiza kuri interineti, cyangwa mu isosiyete y'ibyuma yo mu gace utuyemo, menya neza ko wabonye ibyuma bikwiye, ukoreshejeIsesengura rya XRF, uzaba ufite ubwenge buhamye bwo kubona ibyuma bikwiye ukeneye.
