1. Guhitamo ibikoresho
Ibiceri bya feza muri rusange bikoresha ifeza isanzwe ifite ubuziranenge bwa 999, kandi ubuziranenge bwa 925 na 900 ni bwo bukoreshwa cyane ku rwego mpuzamahanga. Ibiceri bya zahabu muri rusange bikozwe mu muringa wa zahabu na feza cyangwa zahabu nka 999999 na 22K. Zahabu na feza byombi bitunganywa kandi bigategurwa na ment binyuze mu gutunganya electrolytic, kandi bigasesengurwa mu tudomo n'ibikoresho bigezweho. Ibisubizo by'isesengura bigaragaza amahame yemewe n'iterambere ry'ikoranabuhanga ry'igihugu.

2. Shyira isahani izungurutse
Kuva mu itanura ry'amashanyarazi, icyuma gishongeshejwe gishyirwa mu buryo butandukanye bwa billets binyuze mu mashini icukura idacogora, hanyuma ubuso bugasya hakoreshejwe ikoranabuhanga kugira ngo bukureho imyanda, hanyuma bugakonja hakurikijwe ibisabwa bikomeye cyane ku bidukikije. Ku ruganda rutunganya, agace k'indorerwamo karabagirana gafite ubushobozi bwo kwihanganira ubunini buto cyane karazingirwa, kandi ikosa ntirirenza mm 0.005.

3. Koza no gusukura imigati
Iyo agace gashyizwe mu gasanduku k'umugati karimo ubusa gakubiswe n'umupfundikizo, hagomba kuba hakenewe ko haboneka umugati muto n'inkombe nziza. Ubuso bw'agasanduku k'icyatsi kibisi bwumye hakoreshejwe isuku yihariye. Buri gasanduku k'icyatsi kibisi kapimirwa. Ubuziranenge bw'igipimo cy'ikoranabuhanga bugomba kuba 0.0001g. Gasket zose z'icyatsi kibisi zitujuje ubuziranenge zigomba gukurwaho. Shyira gasket z'icyatsi kibisi zikenewe mu gikoresho gisukuye gifite umupfundikizo hakurikijwe ingano yagenwe yo gushyiramo.

4. Ifumbire
Igishushanyo mbonera cy’ibihumyo ni ikintu kidasanzwe kandi cy’ingenzi mu gikorwa cyo gucuranga. Nyuma yo gusuzuma no kwemeza insanganyamatsiko n’igishushanyo, binyuze mu gushushanya ibihumyo mu buryo bugoye kandi bunoze, hamwe no gukoresha ibikoresho bigezweho bigezweho, intego yo gushushanya yashyizwe ku gihumyo.

5, Inyandiko
Gucapa ibiceri bikorerwa mu cyumba gisukuye gifite umwuka uyungurura. Ivumbi rito iryo ari ryo ryose ni ryo shingiro ry’isuka ry’ibiceri. Ku rwego mpuzamahanga, igipimo cyo gucapa ibiceri gikunze kuba 10%, mu gihe igipimo cyo gucapa ibiceri bifite umurambararo munini n’ubuso bunini bw’indorerwamo kigera kuri 50%.

6. Uburinzi n'ibipfunyika
Kugira ngo ibara ry’ibiceri by’urwibutso bya zahabu na feza rikomeze kuba ryiza mu gihe runaka, ubuso bwa buri giceri bugomba kurindwa. Muri icyo gihe, gishyirwa mu gasanduku ka pulasitiki, kigafungwa na firime ya pulasitiki, hanyuma kigashyirwa mu gasanduku kabigenewe. Ibikoresho byose byarangiye bigomba kugenzurwa cyane.
