Cyanidation ndiyo imwe yenzira huru dzekubatsira migodhi yegoridhe, uye inogona kukamurwa kuita mhando mbiri: inosimudzira cyanidation uye percolation cyanidation.Mukuita uku, kusanganisa cyanide goridhe kuburitsa maitiro anonyanya kusanganisira cyanide-zinc kutsiva maitiro (CCD neCCF) uye isina-sefa cyanide kabhoni slurry (CIP neCIL).Iyo inowanzo shandiswa goridhe midziyo yekuparadzanisa inonyanya zinc poda yekutsiva mudziyo, leaching inosimudzira tangi, yakaderera kushandiswa nekukurumidza desorption electrolysis system.
1. Zinc poda inotsiva mudziyo inzira inoshandisa zinc poda kuburitsa goridhe kubva mumvura yakakosha mucyanide-zinc yekutsiva maitiro.Chigadzirwa chazvino chakanangana nemidziyo yegoridhe yekubatsira iyo ine yakakwira sirivheri mune yegoridhe ore.Mushure mekuchenesa mvura yakakosha uye kubvisa oxygen, zinc poda yekutsiva mudziyo inowedzerwa kuti iwane dhaka regoridhe.Kana zinc poda (sirika) ichishandiswa kutsiva kunaya uye kudzoreredza goridhe, iyo inonzi cyanide-zinc kutsiva nzira (CCD neCCF) inogona kushandiswa mukugadzira maitiro, kana zinc poda kutsiva inogona kushandiswa kurapa zvinodhura mhinduro (leaching mhinduro. )Kazhinji kutaura, pamusoro pemigodhi yegoridhe ine yakakwira sirivheri zvemukati, zinc poda yekutsiva michina inogona zvakare kushandiswa kugadzirisa goridhe concentrate inoda kuvandudza giredhi ravo.
2. Double impeller leaching stirring tank The double impeller leaching stirring tank inowanzoshandiswa mineral processing equipment mu carbon slurry gold extract process (CIP method uye CIL).Pasi pekukwevera uye chiito chekusimudzira chechipiri, slurry inoyerera ichidzika kubva pakati, inopararira kuburikidza nemapuranga akapoteredzwa ekunyorovesa, inopinza mhepo pamagumo eshaft, inosanganiswa ne slurry uye inotenderera kumusoro.Mhinduro iyi yakakodzera maapplication ane diki chaiyo giravhiti, yakaderera viscosity uye inononoka kunaya mwero., kana iyo ore particle size iri pamusoro -200 mesh uye iyo goridhe mhinduro yekumisikidza iri pasi pe45%, yunifomu yakamiswa musanganiswa inogona kuumbwa.Absorption uye mamwe mabasa ekusanganisa.MuCIP maitiro ekuisa goridhe, leaching uye adsorption mabasa akazvimirira.Mukushanda kwekutora, iyo leaching process inopedzwa.Saizi, huwandu, uye mamiriro ekushanda ematangi adsorption anotemerwa neiyo adsorption paramita.Iyo CIL maitiro ekuisa goridhe anosanganisira panguva imwe chete leaching uye adsorption mashandiro.Sezvo kuvhiya kuvhiya kuchiwanzotora nguva yakareba kupfuura kuvhiya kweadsorption, saizi yetangi inosimudzira inotarwa neiyo leaching paramita kuona huwandu hweaeration uye dosing.Nekuti mwero wekunyura une chekuita nebasa rekunyungudutswa kwegoridhe, 1-2 mazinga ekutanga-kunyura anowanzo kuitwa pamberi pekunyudzwa kwemupendero kuwedzera kuwanda kwegoridhe rakanyungudutswa mutangi rekushambadza uye kuwedzera nguva yekudonha.
3. Yakaderera-kushandiswa nekukurumidza desorption electrolysis system.Iyo yakaderera-inoshandiswa nekukurumidza desorption electrolysis system seti yegoridhe ore yekupfekedza midziyo inobvisa uye electrolytes goridhe-yakatakura kabhoni kugadzira dhaka regoridhe pasi pekupisa kwakanyanya uye kudzvanywa kwakanyanya.Iyo goridhe-yakarodha kabhoni slurry inotumirwa kune kabhoni yekuparadzanisa skrini (kazhinji mutsara wemutsara unozunguza skrini) kuburikidza nekabhoni pombi kana mhepo inosimudza.Chidzitiro chepamusoro chinoshambidzwa nemvura yakachena kuparadzanisa kabhoni kubva kune slurry.Iyo goridhe-yakatakura kabhoni inopinda kabhoni yekuchengetedza tank, iyo slurry uye inoyerera mvura.Pinda chikamu chekutanga chetangi yeadsorption.Kushandisa yakaderera-simba uye nekukurumidza desorption electrolysis sisitimu yekuwedzera anions inogona kutsiva Au(CN) 2- neAu(CN)2-, uye iyo yakakosha mvura inowanikwa nekubvisa goridhe-yakatakura kabhoni inogona kudzoreredza goridhe rakasimba kuburikidza neionization nzira.Iyo yakaderera simba rekushandisa nekukurumidza desorption electrolysis system ine desorption rate inopfuura 98% pasi pekushisa kwakanyanya (150 ° C) uye high pressure (0.5MPa) mamiriro, uye simba rekushandisa rinongori 1/4 ~ 1/2 yezvakajairwa. system.Iyo isiri-chepfu uye yedivi-effect musanganiswa ine kabhoni activator, inogona kudzoreredza kabhoni.Iyo yakaonda kabhoni haidi kuvandudzwa nenzira yemoto, iyo inochengetedza mutengo wekugadzirisa kabhoni.Iyo goridhe slurry ndeyegiredhi repamusoro, haidi reverse electrolysis, uye iri nyore kubvisa.Panguva imwecheteyo, iyo yakaderera-yekushandisa nekukurumidza desorption electrolysis system inotorawo matanho matatu ekuchengetedza, anoti hungwaru hweiyo system pachayo, iyo otomatiki yekumisikidza uye kuderedza michina, uye inishuwarenzi yekuchengetedza valve.
