Ubucukuzi bw'amabuye y'agaciro Amashanyarazi Amashanyarazi ya Zahabu
Imashini ya gravit gravit igisubizo irazwi cyane mubihugu byinshi bya Afrika nka Zimbabwe, Egiputa na Sudani procedures Gahunda zakazi zirimo guhonyora → gusya → knelson centrifugal concentrator guhitamo （kugirango ubone ubunini bunini bwa zahabu） → kunyeganyeza (guhitamo zahabu nziza iva mu bucukuzi bw'amabuye y'agaciro). Nyuma yo kumenagura, ibuye ryacitsemo ibice bitarenze 20mm. Ibice bishyirwa mu ruganda rutose rwa zahabu, hanyuma bigahinduka ifu nka meshi 100 kugeza 150 (kuva kuri micron 80 kugeza 150). Noneho ibishishwa byakozwe mu ruganda rutose rwimurirwa muri santrifugali ya zahabu, aho bakusanyirizamo zahabu umucanga wirabura. Noneho umurizo ujya kumeza yo kunyeganyega kugirango zahabu isigare.
Ibikoresho bya Zahabu Gravity Gutanga
Ibikoresho bya rukuruzi ya zahabu bizashyirwa mubintu 20ft cyangwa 40ft ukurikije umwanya nuburemere. Kugeza ubu, twohereje ibikoresho bya rukuruzi mu bihugu byinshi, harimo Sudani, Zimbabwe, Mauritania na Misiri.
