intshayelelo

Kwishishini lezemigodi, ingakumbi kwiMigodi emincinci , ukukhutshelwa kweentsimbi ezixabisekileyo ezifana negolide nesilivere kudala kuxhomekeke kwiSodium Cyanide . Nangona kunjalo, ukusetyenziswa kwesodium cyanide kuza neenkxalabo ezibalulekileyo zokusingqongileyo nokhuseleko. Inetyhefu kakhulu kwaye inokubangela ungcoliseko olukhulu kwimithombo yamanzi kunye nomonakalo kwizidalwa zasemanzini. Ngokugxininisa ngakumbi kukhuseleko lokusingqongileyo kunye nemithetho engqongqo kwihlabathi liphela, imigodi emincinci iphantsi koxinzelelo olukhulu lokufumana ezinye iindlela zokukhupha isinyithi. Eli nqaku lihlola ukusetyenziswa kweSodium cyanide Replacement Technologie kwimigodi emincinci, ngenjongo yokubonelela ngokuqonda okubanzi kwezi zisombululo zizinzileyo.

Ukungaphumeleli kweSodium Cyanide kwiMigodi emincinci

Imingcipheko yokusingqongileyo

Iimigodi ezincinci zihlala zingenazo iinkqubo eziphambili zokulawula inkunkuma. Xa kusetyenziswa i-sodium cyanide , kukho umngcipheko omkhulu wokuvuza kwe-cyanide emanzini akufutshane ngexesha lenkqubo yokukhupha. Nokuba yi-cyanide encinci inokuba yingozi kakhulu kwi-ecosystem. Umzekelo, inokukhokelela ekufeni kweentlanzi nezinye izinto eziphilayo zasemanzini, iphazamise lonke uthotho lokutya lwasemanzini. Ukongeza, i-cyanide inokuhlala kwindawo engqongileyo ixesha elide, ibangele umonakalo wexesha elide kumgangatho womhlaba namanzi.

Iingozi Zokhuseleko

Ukuphatha i-sodium cyanide kufuna amanyathelo angqongqo okhuseleko. Imigodi emincinci ayinakusoloko inemithombo yokutyala imali kwizixhobo zokhuseleko ezifanelekileyo kunye noqeqesho lwabasebenzi bayo. Ukuvezwa ngengozi kwisodium cyanide kunokubangela iingxaki zempilo ezimandundu kubasebenzi basezimayini, kubandakanywa ukusilela kokuphefumla kunye nokufa. Ngaphezu koko, xa kwenzeka iintlekele zendalo okanye iingozi, ukugcinwa kunye nokuthuthwa kwe-sodium cyanide kwimigodi emincinci kunokubangela ingozi enkulu kuluntu olujikelezileyo.

Ubuchwephesha obunye kwiSodium Cyanide

I-Thiosulfate Leaching

I-Thiosulfate leaching yenye indlela engeyiyo inetyhefu kune-cyanide-based extraction. Isebenzisa ii-ion ze-thiosulfate ukunyibilikisa igolide kwi-ores. Le ndlela ihambelana nokusingqongileyo njengoko ingakhuphi izinto ezinetyhefu kakhulu. Kwimigodi emincinci, i-thiosulfate leaching inokuba lukhetho olufanelekileyo njengoko lunokusetyenziswa kwiindidi ezahlukeneyo ze-ore. Nangona kunjalo, inakho imingeni. Inokufuna ukuphuculwa kwenkqubo eyongezelelweyo, njengokulawula i-pH kunye nobushushu besisombululo se-leaching ngokuchanekileyo ngakumbi. Kwakhona, iindleko zokusebenza ziphezulu xa kuthelekiswa ne-cyanide leaching, ngokukodwa ngenxa yeendleko ze-reagents ze-thiosulfate kunye nesidingo sezixhobo ezinzima ngakumbi kwezinye iimeko.

I-Chloride Leaching

I-chloride leaching ibandakanya ukusebenzisa i-ion ye-chloride ukunyibilikisa igolide kunye nezinye izinyithi ezivela kwi-ores. Inika imingcipheko esezantsi yokusingqongileyo xa kuthelekiswa necyanide. Imigodi emincinci ingaxhamla kule ndlela njengoko ikwazi ukuqhelana neemeko zendawo. Ngokomzekelo, kwiindawo apho i-chloride-equlethe izinto ezifumaneka ngokulula, iindleko ze-reagents zinokuncitshiswa. Nangona kunjalo, ukulawula iimveliso kunye nenkunkuma evela kwi-chloride leaching kunokuba nzima. I-Chloride - inkunkuma etyebileyo inokufuna unyango olukhethekileyo ukuthintela ukubola kwezixhobo kunye nongcoliseko lokusingqongileyo.

Bioleaching

I-Bioleaching isebenzisa umsebenzi we-microbial ukukhupha isinyithi kwi-ores. Le yindlela ezinzileyo kwaye enobuhlobo ne-eco. Iintsholongwane, ezifana neebhaktheriya ezithile, zinokuqhekeza intsimbi ekrwada zize zikhulule isinyithi. Kwimigodi emincinci, i-bioleaching inenzuzo yokuba kulula ukuseta kwezinye iimeko. Ayifuni izixhobo eziphucukileyo. Nangona kunjalo, ukusebenza kakuhle kwe-bioleaching kunokuthintelwa zizinto ezinje ngohlobo lwe-ore kunye nomsebenzi we-microorganisms. Ezinye ii-ores zisenokungaboli lula ziintsholongwane ezifumanekayo, kwaye ukukhula kunye nomsebenzi we-microorganisms kunokuchatshazelwa ziimeko zokusingqongileyo ezifana nobushushu kunye ne-pH.

Ukusetyenziswa kokusiNgqongileyo - ii-Agents zokunxiba zeGolide ezinobuhlobo

Kukho iiarhente ezahlukeneyo zokubopha igolide ezinobuhlobo nokusingqongileyo ezikhoyo kwimarike ezinokuthatha indawo ye-sodium cyanide. Umzekelo, iarhente yokubopha igolide enobuhlobo nokusingqongileyo ye-"Jinchán" eyenziwe yiGuangxi Senhe High - tech Co., Ltd. ineenzuzo zokuba netyhefu ephantsi, izinga eliphezulu lokubuyisela, kunye nokusebenza okulula. Ezi arhente zingasetyenziswa kwiinkqubo ezifanayo ne-sodium cyanide, ezifana nokukhupha i-heap, ukukhupha ichibi, kunye neenkqubo zeCarbon - in - pulp. Zinokukhupha igolide ngokufanelekileyo kwiintlobo ezahlukeneyo zee-ore, kuquka nezo zinemixholo enzima. Omnye umzekelo yi-CNFREE sodium cyanide substitute, enokusetyenziswa ngokuthe ngqo kwi-gold ore dressing kunye nokucocwa ngaphandle kokutshintsha izixhobo zokuqala kunye nenkqubo ye-cyaniding, ifezekisa ngokwenene injongo yokukhusela okusingqongileyo okuluhlaza.

Imingeni kunye nezisombululo ekusebenziseni obunye ubuchwephesha kwiMigodi emincinci

Iindleko - ukusebenza kakuhle

Omnye wemiceli-mngeni engundoqo kwimigodi emincinci ekwamkeleni obunye ubuchwephesha ziindleko- ukusebenza ngempumelelo. Iindlela ezininzi ezizezinye, ezifana ne-thiosulfate leaching, zinokuba neendleko eziphezulu zotyalo-mali lokuqala lwezixhobo kunye nee-reagents. Ukujongana noku, imigodi emincinci ingaqwalasela ukusebenzisana namaziko ophando okanye iinkampani ezinkulu zemigodi ukwabelana ngeendleko zophando kunye nophuhliso lweendleko ezingaphezulu - iinkqubo ezisebenzayo. Ukongeza, inkxaso-mali karhulumente okanye inkuthazo inokubonelelwa ukukhuthaza imigodi emincinci ukuba yamkele obu buchwepheshe buzinzileyo.

Ingcali yezobugcisa
