Amanzi wesigubhu se-DRUM asetshenziswa kabanzi ngokusebenza kokususwa kwe-Iron emikhakhelweni ehlukahlukene, kufaka phakathi isilayidi somlilo, amalahle, amaminerali angewona ama-metallic, kanye nezinto zokwakha. Abahlukanisi basusa ngempumelelo ukungcoliswa kwensimbi kusuka ezintweni ezifana nama-slags, ama-ores kanye nezinhlanganisela zokwakha. Nge

Ukuze uqhubeke nokunyusa ukwakhiwa kwesiko lebhizinisi, uthuthukise ubumbano lwenkampani, bese udala umkhathi ovuselelekile futhi ojabulayo noNyaka Omusha, u-Guangxi Ruijie Slag ExedIft Co, Ltd. Babambe umhlangano waminyaka yonke kanye nonyaka wokugcina ngonyaka kuJanuar

Ukucubungula amaminerali kuyisigaba esibalulekile ekukhishweni nasekuvuseleleni amaminerali abalulekile avela ku-ore. Ukufeza ukucubungula okusebenzayo nokusebenza okusebenzayo, kusetshenziswa imishini namasu ahlukahlukene. Enye imishini enjalo ethole ukunakwa okuphawuleka kakhulu eminyakeni yamuva yimishini yejig.
