Isisombululo somxhuzulane esimanzi se-pan mill sithandwa kakhulu kumazwe amaninzi ase-Afrika afana neZimbabwe, iYiphutha neSudan, Iinkqubo zokusebenza ziyatyumza→isila→i knelson centrifugal concentrator select(ukufumana ubungakanani obukhulu begolide esimahla)→itafile engcangcazelayo(ukukhetha igolide entle. ukusuka kwintsimbi ekrwada) . Okokuqala faka ilitye kwisityuli somhlathi, imodeli yesiqhelo yokutyumza yi-PE250x400, umthamo wayo uyi-10 ukuya kwi-20 yeetoni ngeyure.Emva kokutyumza, ilitye liphulwa libe ngamaqhekeza angaphantsi kwama-20mm.La masuntswana afakwa kwi-pan yokusila emanzi yegolide, kwaye ayagutywa abe ngumgubo malunga ne-100 ukuya kwi-150 mesh (ukusuka kwi-80 ukuya kwi-150 micron).Emva koko udaka olwenziwe kwi-pan yokusila emanzi lugqithiselwa kwi-centrifugal concentrator yegolide, apho kuqokelelwa intlabathi emnyama yegolide.Emva koko umsila uya kwitafile eshukumayo ukuze iphinde ibuyiselwe igolide eseleyo.
Isixhobo segolide somxhuzulane siya kulayishwa kwisikhongozeli se-20ft okanye 40ft ngokwesithuba kunye nobunzima.Ukuza kuthi ga ngoku, sithumele izixhobo zomxhuzulane kumazwe amaninzi, aquka iSudan, iZimbabwe, iMauritania ne-Egypt.
