As imashini ya zahabuuwukora, dusangiye ubumenyi bwa zahabu kumitako kubakiriya.

Zahabu ivanze nicyuma nkumuringa na feza mugihe ikoreshwa mugukora imitako.Zahabu yera ntabwo ari ikintu ubwacyo, ahubwo zahabu ivanze nibindi byuma kugirango irebe ifeza.Ibyuma bikoreshwa cyane muri zahabu yera ni nikel na palladium, cyangwa zinc cyangwa amabati.

Kuvanga AMASOKO YO GUKORA JEWELERY

Waba uzi ibyuma wambaye?

Urashobora gutangazwa no kumenya umubare wibyuma bitandukanye hamwe nuruvange rwinjiye mumitako yawe no mumubiri wawe.Kuri William Rowland twishimiye gutanga ibyuma bisukuye kandi bivanze ninganda zitandukanye kwisi.

Ubwoko bwibyuma byingenzi dutekereza kubijyanye no gukora imitako ni ifeza na zahabu, ariko mubyukuri imitako myinshi ntabwo ikozwe muri feza cyangwa zahabu.Impamvu yabyo nuko muburyo bwabo bwera, ifeza na zahabu byombi byoroshye kuburyo bidakwiriye imitako myinshi.Ibyuma byose bifite imiterere yihariye ituma bikwiranye nimirimo yihariye, niyo mpamvu ari ngombwa kuvugana numucuruzi wicyuma ufite uburambe mugihe utumiza.

Ubwoko bwa feza bwera cyane bwitwa 'feza nziza' kandi ibi bikoreshwa cyane mubimasa, aho kuba imitako cyangwa ifaranga, kuko byoroshye.Ifeza nayo irashobora kwanduzwa cyane, kandi kuvanga nibindi byuma birashobora gukumira ibi.Ahubwo, ifu ivanze, sterling ikoreshwa aho.Ibi bifite 92.5% byera, ariko ibisigaye bivangwa nibindi byuma nkumuringa, zinc cyangwa silicon.

Mu buryo nk'ubwo, zahabu muburyo bwayo busanzwe ibikwa kuri bullion, kubera ko yoroshye kandi byoroshye guhinduka nabi mumitako cyangwa ifaranga.Zahabu ivanze nicyuma nkumuringa na feza mugihe ikoreshwa mugukora imitako.Zahabu yera ntabwo ari ikintu ubwacyo, ahubwo zahabu ivanze nibindi byuma kugirango irebe ifeza.Ibyuma bikoreshwa cyane muri zahabu yera ni nikel na palladium, cyangwa zinc cyangwa amabati.

Hariho kandi kuvanga zahabu zitandukanye kugirango habeho amabara n'ingaruka zitandukanye.Zahabu ya roza ni uruvange rwa zahabu yumuhondo, ifeza numuringa, kugirango habeho ibara ryijimye, kandi ibyuma bishya bivangavanze byimitako bihora bivumburwa.

Kuri Hasung tuzi ibyuma kandi tumaze gukora ibikoresho by'agaciro by'agaciro kuva mu 2000 dufite imyumvire idasanzwe yimiterere yabyo hamwe nibisabwa kubantu benshi basaba.Mugihe uguze ibyuma ukoresheje isoko, haba mugutumiza mumaduka kumurongo, cyangwa mumasosiyete yicyuma, menya neza ko ubona ibyuma bikwiye, ukoresheje aIsesengura XRF, uzagira ibitekerezo bisobanutse kugirango ubone ibyuma bikwiye ukeneye.
