Makiyi Paramita Anobata Goridhe Kudzoreredza Mwero muSodium Cyanide Leaching

ziviso

Kubvisa goridhe kubva mugoridhe nenzira yeSodium cyanide inzira inoshandiswa zvakanyanya muindasitiri yekuchera goridhe. Zvisinei, kushanda zvakanaka kwekudzoreredza goridhe mukuita uku kunokonzereswa nematanho akati wandei akakosha. Kunzwisisa maparameter aya kwakakosha pakuvandudza maitiro ekuburitsa goridhe, kuwedzera kudzoreredza goridhe, uye kuderedza mari yekugadzira. Chinyorwa chino chichaongorora zvinhu zvikuru zvinokanganisa mwero wekudzoreredza goridhe panguva yekubviswa kweSodium cyanide.

Kukuya Fineness

Pamberi peiyo cyanide leaching process, ore yegoridhe inoda kugadziridzwa, nekukuya riri danho rakakosha. Chinangwa chekugaya ndechekuwana monomer dissociation yegoridhe, kuiparadzanisa kubva kune gangue zvicherwa zvakanyanya sezvinobvira. Kana goridhe riri mudombo rakanyatsonamirwa kana kuvharwa, kukuya kwakakodzera kunokosha. Kana kukuya kwakakasharara, zvimedu zvegoridhe zvinogona kusanyatsobuda pachena, zvichizokonzera kusakwana kwekuchenesa uye kudzoreredza goridhe rakaderera. Kune rumwe rutivi, kupfutidza - kugaya hakungo wedzera mutengo wekugaya chete asiwo kunounza mamwe maitiro asina kunaka. Pamusoro-pasi zvimedu zvinogona kuunza tsvina yakawanda inobvisika mu leachate, iyo inogona kuita nemushonga wecyanide, zvichitungamira mukuraswa kwecyanide. Uyezve, kupfuudza-kukuya kunogona kukonzera kuomerwa mukuparadzana kwakasimba - kwemvura, uye kunogona kutungamira mukurasikirwa kwegoridhe rakanyungudika. Kazhinji, kune ore yegoridhe ine yakatsetseka - yakasarudzika goridhe, saizi yekukuya ye - 38 μm ine chiyero chemukati che 75% inogona kuve nechokwadi chekugadzirisa zvirinani uchidzora mutengo wekukuya.

Kushandiswa kweSodium Cyanide

Huwandu hweSodium Cyanide inowedzerwa mukubvisa gold ine simba guru pahuwandu hwekudzorerwa kwegoridhe. Mukati mehuwandu hwakati, huwandu hwecyanide hunoenderana nehuwandu hwekubviswa kwegold ore pulp. Kana huwandu hwecyanide huri pasi, mhedzisiro yekubviswa kwegold haina kunaka, uye kumhanya kwekubviswa kwegold kunononoka. Izvi hazvingowedzere nguva inodiwa yekubviswa kwegold chete asiwo zvinogona kukonzera kubviswa kwegold kusina kukwana, nokudaro zvichideredza huwandu hwekudzorerwa kwegold. Zvisinei, kana huwandu hwecyanide hwakanyanya, mushure mekunge goridhe rasvika padanho rakati, kuwedzera kwehuwandu hwekudzorerwa kwegold hakuzove pachena. Pane kudaro, zvichakonzera kurasika kwecyanide uye kuwedzera mutengo wekugadzira. Semuenzaniso, pakubvisa gold concentrate kubva mugold ore nehukuru hwetinji yakacheneswa, Dosage yesodium cyanide inonyanya kukodzera pa1.5 - 3.0 kg/t. Mukugadzirwa chaiko, mafekitori ekuchera migodhi anofanirwa kuona huwandu hwakakodzera hwesodium cyanide zvichienderana nehunhu hweore yavo uye bvunzo dzebeneficiation.

Kuwanda kweLime

Lime inowedzerwa kune cyanide mhinduro se alkali inodzivirira. Cyanide ions mumushonga ine makemikari asina kugadzikana uye ari nyore kushandura sehydrogen cyanide gasi, izvo zvinozokonzera kurasikirwa kwesodium cyanide solution. Nekuwedzera lime, iyo pulp inogona kuchengetedzwa pane yakakodzera alkalinity, iyo inobatsira kuvandudza kugadzikana kweiyo cyanide mhinduro. Zvinoenderana nekuongororwa kwebvunzo, mwero wekudonha wegoridhe unovandudzwa zvakare mushure mekuwedzera lime. Kana huwandu hwelime hwawedzerwa 2 kg/t zvichikwira, pH kukosha kwemupupuri kuri pakati pe 11 - 12. uye chiyero chekubuda kwegoridhe mu pulp hachina kugadzikana. Nekudaro, kana huwandu hweraimu hwakakurisa, hunogonawo kuve nemhedzisiro yakaipa pakuita leaching, sekushandura chimiro chemuviri uye chemakemikari emupuru, izvo zvinogona kukanganisa kuita pakati pecyanide negoridhe.

Leaching Pulp Concentration

Iko kusungirirwa kweiyo leaching pulp chinhu chinokanganisa zvakananga kumhanya kweleaching uye kugona kwegoridhe. Kazhinji, kana iyo yekumisikidzwa kweiyo leaching pulp yakadzikira, kuyerera kweiyo pulp kwakanaka, izvo zvinoita kuti pabatane pakati peiyo cyanide mhinduro uye zvimedu zvegoridhe, uye nekudaro kugona kwekudonha kwegoridhe kunenge kwakakwira. Zvisinei, iyi mamiriro ezvinhu inoda kuwedzera kwehuwandu hwemumiririri akawedzerwa. Panguva imwecheteyo, saizi yemidziyo uye mari yekudyara ichawedzerawo. Kusiyana neizvi, kana iyo pulp concentration yakanyanyisa, viscosity yepulp ichawedzera, iyo fluidity ichave yakashata, izvo zvinotadzisa kupararira kweiyo cyanide mhinduro uye kusangana nezvikamu zvegoridhe, zvichikonzera kudzikira kwekumhanya kweleaching uye kugona kwegoridhe. Kune ore yegoridhe ine yakatsetseka - yakaomeswa particle size, iyo pulp concentration inogona kuchengetedzwa inosvika 20% - 33% kuve nechokwadi chekuita leaching yakanaka. Mukugadzirwa chaiko, zvidyarwa zvemigodhi zvinogona kunyatsogadzirisa kusungirirwa zvinoenderana nemamiriro chaiwo, asi haifanirwe kunge yakanyanya kukwirira.

Leaching Time

Iyo leaching nguva zvakare chinhu chakakosha chinokanganisa goridhe kudzoreredza mwero muiyo cyanidation process. Kusarudza nguva yakakodzera yeleaching kunogona kuve nechokwadi chekuti zvimedu zvegoridhe zvanyungudika zvizere. Nekudaro, panguva yekunyungudika kwegoridhe zvimedu, mamwe matsvina ari mupulp acharamba achinyungudika. Sezvo nguva yekuchenesa ichirebesa, kunyungudika kunopfuurira uye kuunganidzwa kwetsvina iyi kunogona kukanganisa kunyungudika kwegoridhe, uye kunyange kutadzisa kunyura kwegoridhe. Uye zvakare, iyo zvakare - yakareba leaching nguva inoda kumisikidzwa kweyakakura leaching michina uye masaiti, izvo zvinozowedzera mutengo wekugadzira. Kune ore yegoridhe ine yakatsetseka-yakaomeswa particle size, zviri nani kuchengeta cyanidation leaching nguva paanenge maawa mana. Kana nguva yekudonha inopfuura maawa makumi maviri nemana, kubuda kwegoridhe kungangodzivirirwa, uye goridhe ion concentration mumvura yakakosha inodzikira zvakare.

mhedziso

Munzira yekuburitsa goridhe neSodium cyanide , zvinhu zvakaita sekukuya kutetepa, huwandu hwesodium cyanide, huwandu hwe lime, huwandu hwe pulp inobuda, uye nguva yekuburitsa zvese zvine basa guru pakuona huwandu hwegoridhe rinobuda. Mafekitori ekuchera anofanira kuita bvunzo dzakadzama dzekuvandudza goridhe zvichienderana nehunhu hweore yavo kuti vagadzirise zvinhu izvi. Nekuita izvi, havangogone chete kuvandudza huwandu hwegoridhe rinobuda asiwo kuderedza mari yekugadzira uye kukanganisa nharaunda, vachiwana budiriro inoenderera mberi muindasitiri yekuchera goridhe.
