Makiyi Paramita Anobata Goridhe Kudzoreredza Mwero muSodium Cyanide Leaching

ziviso

Sodium cyanide leaching inzira inoshandiswa zvakanyanya muindasitiri yekuchera goridhe kuburitsa goridhe kubva mumatombo. Nekudaro, kugona kwekudzoreredza kwegoridhe mukuita uku kunopesvedzerwa nematanho akakosha ma paramita. Kunzwisisa ma paramita aya kwakakosha pakugadzirisa maitiro ekuregedza, kuwedzera kudzoreredza goridhe, uye kuderedza mitengo yekugadzira. Ichi chinyorwa chichaongorora zvinhu zvikuru zvinokanganisa Gold recovery rate munguva Sodium cyanide leaching.

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

Kuwanda kwe Sodium Cyanide yakawedzerwa mukuita leaching ine chekuita kwakakura padanho rekudzoreredza goridhe. Mukati mehumwe danho, huwandu hwecyanide hunoenzana nechiyero chekudonha chegoridhe ore pulp. Kana iyo cyanide yemukati yakadzikira, iyo goridhe leaching mhedzisiro haina kunaka, uye kumhanya kweleaching kunononoka. Izvi hazvingowedzeri chete nguva inodiwa pakudonha asi zvakare zvinogona kukonzera kusazara kwegoridhe, nokudaro kudzikisa mwero wekudzoreredza goridhe. Nekudaro, kana huwandu hwecyanide hwakanyanya, mushure meiyo leaching yegoridhe yasvika kune imwe nhanho, kuwedzera kweiyo goridhe kudzoreredza mwero hakuzove pachena. Panzvimbo iyoyo, zvinokonzeresa kutambisa cyanide uye kuwedzera mutengo wekugadzira. Semuyenzaniso, kana uchibvisa goridhe concentrate kubva goridhe ore ine yakanaka - grained particle size, the Chiyero che sodium cyanide inonyanya kukodzera pa 1.5 - 3.0 kg / t. Mukugadzirwa chaiko, zvidyarwa zvemigodhi zvinoda kuona huwandu hwakakodzera hwe sodium cyanide zvinoenderana nehunhu hweore yavo uye bvunzo dzekubatsirikana.

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

Mu Sodium cyanide leaching maitiro ekubvisa goridhe, maparamendi akadai sekukuya kutsetseka, dosage yesodium cyanide, huwandu hweraimu, leaching pulp concentration, uye nguva yekuregedza zvese zvinotora basa rakakosha mukuona chiyero chekudzosa goridhe. Zvidyarwa zvemigodhi zvinofanirwa kuita bvunzo dzakadzama dzekubatsirikana zvinoenderana nehunhu hweore yavo kuti ikwidze aya ma paramita. Nekuita izvi, havangogone kuvandudza mwero wekudzoreredza goridhe chete asiwo kuderedza mitengo yekugadzira uye kukanganisa kwezvakatipoteredza, kuwana budiriro inoenderera muindasitiri yekuchera goridhe.
