Inkqubo yeCarbon Slurry yokutsalwa kweGolide: Ukufezekisa i-94% yexabiso leGolide eliPhezulu lokuBuyisa

Kwicandelo lokumbiwa kwegolide kunye nokukhutshelwa kwayo, ukusebenza kakuhle kunye namazinga aphezulu okufumana kwakhona kubaluleke kakhulu. Inkqubo yeCarbon Slurry ivele njengeyona ndlela iphambili, eyaziwa ngokukwazi kwayo ukufezekisa iGolide Recovery Rate efikelela kwi-94%. Eli nqaku lijonga kwiingxaki zenkqubo yeCarbon slurry, lihlola iingenelo zayo, iindlela zokusebenza, kunye nokubaluleka kwayo kushishino lwemigodi yegolide lwanamhlanje.

Ukuqonda iNkqubo yeCarbon Slurry

Inkqubo ye-carbon slurry yindlela esetyenziswa ngokubanzi yokukhupha igolide kwi-ore. Ibandakanya uthotho lwamanyathelo acwangciswe kakuhle avumela ukwahlulwa ngokufanelekileyo kwegolide kwizimbiwa ezingqongileyo.

Ukulungiselela intsimbi

Inkqubo iqala ngokutsalwa kwegolide-intsimbi ekrwada ephuma emgodini. Intsimbi ekrwada ithuthwa isiwe kumzi-mveliso, apho ithi icunyuzwe kwaye isila. Eli nyathelo libalulekile njengoko linciphisa intsimbi ekrwada ukuba isebenze ngokucokisekileyo, inyusa indawo engaphezulu efumanekayo yokusabela kwimichiza elandelayo. Intsimbi ekrwada etyunyuziweyo kunye nomhlaba emva koko ixutywa namanzi ukwenza i-slurry, elungele inqanaba elilandelayo lenkqubo.

Cyanidation

I-cyanidation linyathelo elibalulekileyo kwinkqubo ye-carbon slurry. Kweli nqanaba, isisombululo se- cyanide songezwa kwi-slurry. I-cyanide isabela negolide kwi-ore, iyiguqula ibe yigolide enyibilikayo - i-cyanide complexes. Le mpendulo yenzeka kwiitanki ezinkulu ezivuthuzayo, ukuqinisekisa ukuba isisombululo se-cyanide sixubana kakuhle ne-ore slurry, nto leyo eyenza ukuba igolide ikhutshwe kakhulu.

Ufakelo lweCarbon olusebenzayo

Emva kokuba igolide iguqulelwe kwi-soluble complexes, ikhabhoni esebenzayo yongezwa kwi-slurry. Ikhabhoni esebenzayo inesakhiwo esinemingxuma ephezulu, ebonelela ngommandla omkhulu we-adsorption. Igolide - i-cyanide complexes itsalwa kumphezulu wekhabhoni esebenzayo, apho i-adsorbed. Le nkqubo ikhetha kakhulu, kunye nekhabhoni evunyiweyo ekhetha igolide - i-cyanide complexes ngaphezu kwezinye izinto ezikwi-slurry. I-adsorption yegolide kwikhabhoni esebenzayo yinkqubo yekhemikhali yendalo, apho ii-ion zegolide-cyanide zibanjwa kumphezulu wekhabhoni ngokusebenzisa amandla ohlukeneyo kunye nokunxibelelana kweekhemikhali kunye namaqela asebenzayo kwikhabhoni.

Ukwahlulwa kweKhabhoni elayishiweyo

Emva kwenkqubo ye-adsorption, ikhabhoni esebenzayo, ngoku ilayishwe ngegolide, kufuneka ihlulwe kwi-slurry eseleyo. Oku kufumaneka ngokuqhelekileyo ngokusebenzisa izikrini okanye ezinye iindlela zokwahlula. Ikhabhoni elayishiweyo eyahlukileyo ilungele inyathelo elilandelayo lenkqubo, elibandakanya ukubuyiswa kwegolide kwikhabhoni.

UkuBuyiswa kweGold kwiCarbon eLayishiweyo

Kukho iindlela ezahlukeneyo zokufumana igolide kwikhabhoni elayishiweyo. Enye indlela eqhelekileyo kukukhupha igolide kwikhabhoni, apho i-gold-cyanide complexes zisuswa kwikhabhoni kusetyenziswa isisombululo esishushu nesixineneyo seSodium Cyanide kunye ne-sodium hydroxide. Isisombululo segolide-cyanide esisusiweyo emva koko sifakwa kwi-electrolysis okanye ezinye iindlela zokunciphisa igolide kwimo yayo yesinyithi. Enye indlela kukunyibilikisa ngqo ikhabhoni elayishiweyo, apho ikhabhoni itshiswa esithandweni, kwaye igolide ifunyanwa kuthuthu oluphumayo.

Izinto ezilungileyo zeNkqubo yeCarbon Slurry

Ixabiso eliphezulu lokuBuyisa iGolide

Inkqubo yolusu lwekhabhoni isebenza kakuhle kakhulu ekufumaneni igolide kwi-ore, kunye nezinga lokubuyisa igolide lilonke elifikelela kwi-94%. Eli zinga liphezulu lokubuyisa libangelwa kukudityaniswa kwenkqubo yeCyanidation , eyinyibilikisa ngempumelelo igolide, kunye nokufunxwa okukhethekileyo kwe-gold-cyanide complexes yi-activated carbon. Ukukwazi ukubuyisa inxalenye enkulu yegolide ekhoyo kwi-ore yinzuzo ebalulekileyo, njengoko kwandisa ixabiso lezoqoqosho lomsebenzi wokwemba.

Ukufaneleka kwiindidi ezahlukeneyo zeentsimbi

Inkqubo ye-carbon slurry iyaguquguquka kwaye ingasetyenziswa kuluhlu olubanzi lwegolide-ethwele intsimbi, kubandakanywa i-ores yomgangatho ophantsi, i-ores ene-oxidized, kunye ne-ores ene-mineralogy eyinkimbinkimbi. Oku kuguquguquka kwenza ukuba kube yinto ekhethwayo kwimisebenzi emininzi yemigodi yegolide kwihlabathi jikelele, njengoko ivumela ukutsalwa kwegolide kwi-ores enokuba nzima okanye ingenamali ukuyiqhuba kusetyenziswa ezinye iindlela.

Inkqubo eyenziwe Lula

Xa kuthelekiswa nezinye iindlela zemveli zokuQokelela iGolide , inkqubo yokulunywa kwekhabhoni inenkqubo elula. Iyasusa isidingo seendlela ezintsonkothileyo nezibizayo zokwahlula ulwelo oluqinileyo ezidla ngokufuneka kwezinye iinkqubo. Ukusetyenziswa kwekhabhoni esebenzayo ukufunxa ngokuthe ngqo kwilunywa kunciphisa inani lamanyathelo okucubungula, nto leyo ekhokelela ekuncipheni kwemali kunye neendleko zokusebenza.

IiNzuzo zokusiNgqongileyo

Ngokwempembelelo yokusingqongileyo, inkqubo ye-carbon slurry ineenzuzo ezininzi. Ukusetyenziswa kwe-cyanide kwindawo elawulwayo nequlathiweyo, kunye neendlela ezifanelekileyo zokulawula inkunkuma, kunceda ukunciphisa ukukhutshwa kwezinto ezinobungozi kwindalo. Ukongeza, izinga eliphezulu lokubuyiswa kwegolide lithetha ukuba intsimbi ekrwada encinci ifuna ukusetyenzwa ukuze ifumane umlinganiselo ofanayo wegolide, kuncitshiswe imo yendalo esingqongileyo yokusebenza kwemigodi.

Iindleko - Ukusebenza kakuhle

Ukudityaniswa kwamazinga aphezulu okubuyisela, inkqubo eyenziwe lula, kunye nefuthe elincitshisiweyo lokusingqongileyo kwenza inkqubo ye-carbon slurry ibe yindleko-esebenzayo. Nangona kukho iindleko zokuqala zenkunzi ezayanyaniswa nokuseka umzi-mveliso wokulungisa, iindleko zexesha elide zokusebenza zisezantsi noko. Ukukwazi ukukhupha igolide ngokufanelekileyo kwiintlobo ngeentlobo ze-ores nako kwandisa inzuzo yokusebenza kwemigodi, njengoko ivumela ukuxhaphazwa kwemithombo enokuthi ithathwa njengento ephantsi.

Izicelo kuShishino lweMigodi yeGolide

Inkqubo ye-carbon slurry isetyenziswa ngokubanzi kwimisebenzi yorhwebo lwemigodi yegolide kwihlabathi jikelele. Imigodi ekwimimandla efana neAfrika, iOstreliya, noMntla Merika isoloko isebenzisa le nkqubo ukuze ikhuphe igolide kwiidipozithi zayo. Umzekelo, kweminye imigodi yase-Afrika, inkqubo yodaka lwekhabhoni iphunyezwe ngempumelelo ukuze kusetyenzwe umgangatho ophantsi, intsimbi ekrwada yegolide eneoksijini eninzi, evumela ukutsalwa kwegolide ebikade ingenamali ukuba iphinde iphinde ibuye. E-Australia, inkqubo isetyenziselwa imigodi enemizimba enzima ye-ore, apho ukulungelelaniswa kwayo kunye namazinga aphezulu okubuyisela abonakaliswe ukuba abaluleke kakhulu.

isiphelo

Inkqubo yekhabhoni eludaka lokutsalwa kwegolide inika intaphane yeenzuzo, kunye nokukwazi kwayo ukufikelela kwireyithi yokufumana igolide iyonke ukuya kuma-94% ibe luphawu olubalaseleyo. Ngokudityaniswa kwe-cyanidation, i-carbon adsorption esebenzayo, kunye nobuchule bokwahlula obusebenzayo, le nkqubo iye yaliguqula ishishini lemigodi yegolide. Ukuguquguquka kwayo, ukulula, izibonelelo zokusingqongileyo, kunye neendleko-ukusebenza kuyenza ibe lolona khetho lukhethwayo ngabembi begolide kwihlabathi liphela. Njengoko imfuno yegolide iqhubeka ikhula, inkqubo ye-carbon slurry ngokungathandabuzekiyo iya kudlala indima ebalulekileyo ekuqinisekiseni ukukhutshwa okuzinzileyo kunye nokusebenzayo kwesi sinyithi sixabisekileyo.
