Isodium cyanide Leaching yeGolide ukusuka kwiBanga eliPhantsi - iBanga leGolide - iBearing Tailings

Kwicandelo lokumbiwa kwegolide kunye nokutsalwa kwayo, ukufunyanwa kwegolide ngokufanelekileyo kwiintsimbi ezimdaka ezikumgangatho ophantsi kunye neentsalela kuye kwaba sisihloko sophando esibaluleke ngakumbi. Njengoko iidiphozithi zegolide ezikumgangatho ophezulu ziphela kancinci kancinci, ukusetyenziswa kwezixhobo ezikumgangatho ophantsi kuye kwatsala ingqalelo engakumbi. Eli nqaku ligxile kwinkqubo yokukhupha igolide kwintsalela yegolide ekumgangatho ophantsi, ngenjongo yokubonelela ngengcaciso ebalulekileyo ngale ndawo.

1. intshayelelo

Igolide yomgangatho ophantsi - iintsimbi ezithwele, eziziintsalela emva kokulungiswa okuphambili kweentsimbi zegolide, zisenomlinganiselo othile wegolide. Ngenxa yobume bezinto ezintsonkothileyo zemineralogical kunye namabanga aphantsi egolide, ukutsalwa kwegolide kwezi ntsalela ngumngeni. Nangona kunjalo, ngophuculo oluqhubekayo lwetekhnoloji yokukhutshwa, kunokwenzeka ukubuyisela ngokwezoqoqosho igolide kubo. I-Cyanide leaching kudala iyindlela esetyenziswa ngokubanzi kwishishini lemigodi yegolide ngokusebenza kwayo okuphezulu kunye nokukhetha ekutsalweni kwegolide.

2. Iindlela zoMfuniselo

2.1 Ukulungiselela iSampuli

Iintsalela zemigodi yegolide ezisetyenzisiweyo kolu vavanyo zaqala zafakwa kwinkqubo ye-granulation. I-granulation linyathelo elibalulekileyo lonyango lwangaphambi kokuba kulungiswe njengoko inokuphucula unxibelelwano phakathi kwamasuntswana entsalela kunye ne-leaching agent, ngaloo ndlela iphucula ukusebenza kakuhle kwe-leaching. Emva kwe-granulation, iintsalela zazilungele uvavanyo lwe-Cyanide leaching olulandelayo.

2.2 Unyango lwangaphambili

Iintsalela zemigodi yegolide zinyangwe kwangaphambili ngesisombululo se-alkaline kangangeeyure ezisi-8. Eli nyathelo lonyango lwangaphambi kwexesha libalulekile kuba linokunceda ekuqhekezeni ezinye zeeminerali ezikwiintsalela, okwenza igolide ifikeleleke lula kwi- agent ye -cyanide leaching. Ikwalungisa imeko-bume ye-pH yeentsalela, nto leyo eluncedo kwimpendulo ye-cyanide leaching elandelayo.

2.3 I-Cyanide Leaching

Ukukhuhla iCyanide kwenziwe kusetyenziswa iSodium cyanide njengesixhobo sokukhuhla. Ubungakanani beSodium Cyanide esetyenzisiweyo yayiyi-1 kg/t. Ixesha lokukhuhla lalimiselwe kwiiyure ezingama-24, kwaye ngexesha lenkqubo yokukhuhla, i-pH yesisombululo igcinwe ngaphakathi koluhlu lwe-10.0 - 12.0. Ixabiso elifanelekileyo le-pH liyimfuneko ukuqinisekisa uzinzo lwe-ion ye-cyanide kunye nokusebenza kakuhle kwempendulo yokukhuhla.

3. Iziphumo zoMfuniselo

Iziphumo zovavanyo zibonise ukuba phantsi kwezi meko zikhankanyiweyo apha ngasentla, izinga lokutsalwa kwegolide lingafikelela ngaphezulu kwama-60%. Oku kubonisa ukuba inkqubo edibeneyo yokutsalwa kwe-alkaline kunye nokutsalwa kwe-cyanide iyasebenza ekutsalweni kwegolide kule ntsalela yegolide. Unyango lwe-alkaline lweeyure ezisi-8, i-1 kg/t yedosi ye -sodium cyanide , ixesha lokutsalwa kwe-24 iiyure, kunye noluhlu lwe-pH oluyi-10.0 - 12.0 lubonelele ngeseti yemilinganiselo elungiselelweyo yale nkqubo yokutsalwa kwegolide.

4. Ukubaluleka kunye neFuture Outlook

Ukusetyenziswa ngempumelelo kwale ndlela yokukhutshwa kwecyanide kwiintsalela zezimbiwa zegolide zodidi oluphantsi kuneempembelelo ezibalulekileyo. Okokuqala, ibonelela ngendlela esebenzayo yokusetyenziswa kwakhona kwegolide ukusuka kwiintsalela zezimbiwa, ukunciphisa inkunkuma kunye nokwandisa ukusetyenziswa kwemithombo. Okwesibini, inokuzisa iinzuzo zoqoqosho kwiinkampani zemigodi ngokufumana kwakhona igolide exabisekileyo kwiintsalela ezilahliweyo ngaphambili.

Kwixesha elizayo, uphando olongezelelweyo lunokwenziwa ukuze kuphuculwe le nkqubo. Umzekelo, ukuphonononga iindidi ezahlukeneyo zonyango lwangaphambili ukuze kuphuculwe izinga lenkululeko yegolide, okanye ukufunda ngokusetyenziswa kwezinye iiarhente zokukhupha amanzi ukunciphisa impembelelo yokusingqongileyo yecyanide. Ukongeza, ukusetyenziswa kobu buchwephesha kwiintlobo ezahlukeneyo zegolide ezikumgangatho ophantsi-ezithwele iitailing kufuneka ziphandwe ukuze kuqinisekiswe ukuba zihambahamba zonke.

Ukuqukumbela, inkqubo yecyanide leaching efundwe apha ibonelela ngesisombululo esithembisayo sokukhutshwa kwegolide kudidi oluphantsi lwegolide-ethwele iimisila, kwaye uphando oluqhubekayo kunye nophuculo kule ndawo luya kuba negalelo kuphuhliso oluzinzileyo lweshishini lemigodi yegolide.
