IziXhobo zeGolide zokuzuzisa iOre-Ukuvula iXabiso elifihlakeleyo leentsimbi zeGolide

Kwilizwe elintsonkothileyo lemigodi yegolide, uhambo olusuka ekrwada, etyeni elingaphawulekiyo ukuya kwibengezelayo, isinyithi esixabisekileyo sixhaswa sisigaba esinye esibalulekileyo: ukuxhamla.Izixhobo zegolide eziluncedoimi njengelitye lembombo lethekhnoloji yale nkqubo, eyilelwe ukwahlula ngokufanelekileyo igolide kwi-ore matrix yayo, ukwandisa amazinga okubuyisela, kunye nokunciphisa impembelelo yokusingqongileyo. Olu luhlu loomatshini alukho malunga nokutsalwa nje; imalunga nokusetyenziswa kobutyebi obukrelekrele.

Inkqubo yokuxhamla iqala ngokutyumza kunye nokugaya. Izityumzi zemihlathi, izityumzi zekhowuni, kunye nezixhobo zokusila zebhola zisebenza ngokulandelelana ukunciphisa intsimbi ekrwada enkulu ibe ngumgubo ocolekileyo, ikhulula amasuntswana egolide ukuba ahlukane. Intliziyo yenzuzo, nangona kunjalo, ilele kubuchule bokwahlula. Apha, izixhobo ezifana ne-centrifugal concentrators, ezifana ne-Knelson kunye ne-Falcon concentrators, zisebenzisa amandla omxhuzulane aphezulu ukubuyisela kwawona masuntswana egolide agqwesileyo. Oomatshini beJig bahlula izinto ezisekwe kwiyantlukwano yoxinaniso, bedala umpompozo wamanzi atyhutyhayo ohluza intsimbi ekrwada, evumela igolide enzima ukuba izinze.

Kwintsimbi ekrwada apho igolide inxulunyaniswa nezinye izimbiwa, oomatshini bokudada bayangena. Bazisa iikhemikhali ezenza iiminerali ezithwele igolide zibe yi-hydrophobic, zibangela ukuba zincamathele kumaqamza omoya kwaye zidada kumphezulu ukuze ziqokelelwe. Ngeli xesha, iitafile ezishukumayo zisebenzisa intshukumo eshukumayo eshukumayo kunye nokuhamba kwamanzi ukwahlula amasuntswana ngoxinaniso kunye nobukhulu, ukuvelisa umjelo ogxininisiweyo wegolide.

Ingenelo yanamhlanje idlulela ngaphaya kokwahlukana nje. Iinkqubo zeCarbon-in-Leach (CIL) kunye neCarbon-in-Pulp (CIP) zimele itekhnoloji ye-adsorption ephezulu, apho ikhabhoni esebenzayo ithatha igolide enyibilikisiweyo kwipulp yecyanide-leached. Ezi nkqubo zincediswa yi-electrowinning kunye nezixhobo zokunyibilikisa, ezigqibezela inkqubo ngokukhupha igolide esulungekileyo kwikhabhoni elayishiwe.

Ixabiso lokwenyani lanamhlanjeizixhobo zegolide ore beneficiationt ilele ekudityanisweni kwayo nobukrelekrele bayo. Iinkqubo zolawulo oluzenzekelayo zilungiselela yonke ipharamitha-ukusuka kwisantya sokutya kunye nomthamo wamanzi ukuya kwidosi yeekhemikhali-ukuqinisekisa ukusebenza kakuhle okuphezulu, ukunciphisa ukusetyenziswa kwamandla, kunye nokunciphisa iindleko zokusebenza. Ngeli xesha lee-ore ezintsonkothileyo kunye nemithetho engqongqo yokusingqongileyo, esi sixhobo siguqukela kwizisombululo eziluhlaza, ezinje ngeesekethe zamanzi avaliweyo kunye nezinye izinto ezinobungozi obuncinci.

Ekugqibeleni, izixhobo zegolide ezikrwada zingundoqo ekuguquleni iidiphozithi eziseludinini zibe ngamaphulo anengeniso nokwandisa ubomi bemigodi esele ikho. Ligorha elingavunywanga eliqinisekisa ukuba isithembiso segolide emhlabeni asifumaneki nje, kodwa siphunyezwe ngokupheleleyo nangentembeko.
