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

Kwinkalo yemigodi yegolide kunye nokuchithwa, ukusebenza kakuhle kunye namazinga aphezulu okubuyisela kubaluleke kakhulu. I Inkqubo yeCarbon Slurry iye yavela njengobuchule obuphambili, obudume ngokukwazi ukufezekisa itotali enomtsalane Ireyithi yoBuyiselo lwegolide ukuya kuthi ga kwi-94%. Eli nqaku liza kujonga kwiingxaki ze ICarbon inkqubo yodaka, ukuhlola iingenelo zayo, iindlela zokusebenza, kunye nokubaluleka kwayo kushishino lwemigodi yegolide yanamhlanje.

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 eliphambili kwinkqubo ye-carbon slurry. Kweli nqanaba, isisombululo se i-cyanide yongezwa kwi-slurry. I-cyanide iphendula kunye negolide kwi-ore, iyiguqule ibe yigolide enyibilikayo - i-cyanide complexes. Oku kusabela kwenzeka kwiitanki ezinkulu eziphazamisekileyo, kuqinisekisa ukuba isisombululo secyanide sixutywa ngokucokisekileyo kunye nodaka lwe-ore, kwandisa ukutsalwa kwegolide.

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 ezininzi zokubuyisela igolide kwikhabhoni elayishiwe. Enye indlela eqhelekileyo yi-desorption, apho igolide - i-cyanide complexes isuswa kwikhabhoni kusetyenziswa isisombululo esishushu, esigxininisiweyo. Isodium cyanide kunye nesodium hydroxide. Igolide ye-desorbed - isisombululo se-cyanide sixhomekeke kwi-electrolysis okanye ezinye iindlela zokunciphisa igolide ngendlela yayo yesinyithi. Enye indlela kukunyibilikiswa ngokuthe ngqo kwekhabhoni elayishiweyo, apho ikhabhoni itshiselwa eziko, ize igolide ibuyiswe kuthuthu olusisiphumo.

Izinto ezilungileyo zeNkqubo yeCarbon Slurry

Ixabiso eliphezulu lokuBuyisa iGolide

Inkqubo yodaka lwekhabhoni isebenza kakuhle kakhulu ekubuyiseni igolide kwintsimbi ekrwada, ngezinga lokubuyiswa kwegolide lilonke ukuya kuma-94%. Eli zinga liphezulu lokuchacha kubalelwa kwindibaniselwano ye Cyanidation inkqubo, enyibilikisa ngempumelelo igolide, kunye ne-adsorption ekhethiweyo yegolide - i-cyanide complexes ngekhabhoni esebenzayo. Ukukwazi ukubuyisela umlinganiselo omkhulu wegolide ekhoyo kwintsimbi ekrwada yinzuzo ebalulekileyo, njengoko iphakamisa ixabiso lezoqoqosho lomsebenzi wokumbiwa kwemigodi.

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 zemveli Ukutsalwa kwegolide iindlela, inkqubo yodaka lwekhabhoni inenkqubo eyenziwe lula. Iphelisa imfuneko yobuchule obuqinileyo kunye neendleko eziqinileyo - zokwahlula ulwelo ezisoloko zifuneka kwezinye iinkqubo. Ukusetyenziswa kwekhabhoni esebenzayo kwi-adsorption ngokuthe ngqo kwi-slurry kunciphisa inani lamanyathelo okucubungula, okukhokelela kwixabiso eliphantsi 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.
