Izisetshenziswa Zokuhlomula Insimbi Yegolide - Ukuvula Ivelu Efihliwe Yezinsimbi Zegolide

Ezweni eliyinkimbinkimbi lezimayini zegolide, uhambo olusuka edwaleni eliluhlaza, elingaphawuleki ukuya etsheni elicwebezelayo, eliyigugu lixhaswe yisigaba esisodwa esibalulekile: ukuhlomula.Imishini yokuhlomula i-ore yegolideime njengesisekelo sobuchwepheshe sale nqubo, eklanyelwe ukuhlukanisa kahle igolide ne-ore matrix yayo, ikhulise amanani okuthola kabusha, futhi inciphise umthelela wendawo. Lolu chungechunge lwemishini alukona nje ukukhishwa; imayelana nokusetshenziswa kwezinsiza ezihlakaniphile.

Inqubo yokuhlomula iqala ngokuchotshozwa nokugaya. Izigayo zemihlathi, izigayo zekhoni, nezigayo zamabhola zisebenza ngokuhambisana ukuze kuncishiswe izingcezu ezinkulu ze-ore zibe yimpushana, zikhulule izinhlayiya zegolide ukuze zihlukane ngokulandelayo. Inhliziyo yokuhlomula, nokho, ilele kumasu okuhlukanisa. Lapha, izinto zokusebenza ezifana nezigxili ze-centrifugal, njengezikhonzi ze-Knelson ne-Falcon, zisebenzisa amandla amakhulu adonsela phansi ukuze zibuyisele ngisho nezinhlayiya zegolide ezinhle kakhulu. Imishini ye-Jig ihlukanisa izinto ezisetshenziswayo ngokusekelwe ekwehlukeni kokuminyana, idale ukugeleza kwamanzi aphephukayo ahlukanisa insimbi, okuvumela igolide elisindayo ukuthi lizinze.

Kuma-ores lapho igolide lihlotshaniswa namanye amaminerali, imishini yokuntanta iyangena. Zethula amakhemikhali enza amaminerali anegolide abe yi-hydrophobic, awenze anamathele kumabhamuza omoya futhi antante phezulu ukuze aqoqwe. Phakathi naleso sikhathi, amatafula anyakazayo asebenzisa ukunyakaza okunyakaziswa kahle nokugeleza kwamanzi ukuze ahlukanise izinhlayiya ngokuminyana nosayizi, okukhiqiza umfudlana wegolide ogxilile.

Ukuhlomula kwesimanje kudlulela ngalé kokuhlukana nje. Amasistimu we-Carbon-in-Leach (CIL) kanye ne-Carbon-in-Pulp (CIP) amele ubuchwepheshe besikhangiso obuthuthukisiwe, lapho ikhabhoni ecushiwe ithwebula igolide elincibilikisiwe lisuka ku-cyanide-leached pulp. Lezi zinhlelo ziphelezelwa imishini yokuwina ugesi kanye nokuncibilikisa, okuphothula inqubo ngokukhipha igolide elimsulwa kukhabhoni elayishiwe.

Inani langempela lanamuhlaigolide ore beneficiation equipment ilele ekuhlanganisweni nasekuhlakanipheni kwayo. Amasistimu okulawula azenzakalelayo alungiselela yonke ipharamitha—kusuka kusilinganiso sokuphakelayo kanye nevolumu yamanzi kuye esilinganisweni samakhemikhali—ukuqinisekisa ukusebenza kahle okuphezulu, ukwehlisa ukusetshenziswa kwamandla, nokwehlisa izindleko zokusebenza. Enkathini yezinsimbi eziyinkimbinkimbi ezikhulayo kanye nemithetho eqinile yezemvelo, lezi zisetshenziswa ziguqukela ezixazululweni eziluhlaza, njengamasekhethi amanzi avaliwe kanye nezinye izinto ezinobuthi obuncane.

Ekugcineni, impahla yegolide yokuhlomula insimbi iyisihluthulelo sokuguqula idiphozithi encane ibe yibhizinisi elinenzuzo kanye nokwelula impilo yezimayini ezikhona. Yiqhawe elingaculwa eliqinisekisa ukuthi isithembiso segolide emhlabeni asitholakali nje kuphela, kodwa sifezeka ngokugcwele nangokuzibophezela.
