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 concentrated selection （kugirango ubone ubunini bunini bwa zahabu） → kumeza (guhitamo zahabu nziza) uhereye ku bucukuzi bw'amabuye y'agaciro) .Banza ushyire ibuye mu rwasaya, icyitegererezo gisanzwe ni PE250x400, ubushobozi bwa toni 10 kugeza kuri 20 mu isaha.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 centrifugal ya centrifugal, aho zegeranya zahabu umucanga wumukara.Noneho umurizo ujya kumeza yo kunyeganyega kugirango zahabu isigaye.
