Kuburitsa Tekinoroji yeDirect Electrolytic Kubvisa Goridhe kubva kuCyanide - Leaching Pregnant Solution

Pakati pezvakasiyana Kuchera goridhe tekiniki, ivo Direct electrolytic kutorwa yegoridhe kubva cyanide - Leaching pamuviri mhinduro iri kubuda senzira yakakurumbira muindasitiri yemigodhi. Zvino, ngationgororei zvakadzama mune iyi yakasarudzika uye yakakosha tekinoroji.

I. Basic Principle: Iyo "Shanduko" yeGoridhe Inotungamirirwa neMagetsi Azvino

Cyanide - leaching ane nhumbu mhinduro, yakakosha yepakati mukubvisa goridhe maitiro, kunyanya ine goridhe muchimiro chegoridhe - cyanide complex anion. Au(CN)_2^-. Kana imwe yakananga - yazvino magetsi yakabatana, shanduko dzinoshamisa dzinotanga mukati mesero re electrolytic. Pasi pesimba remunda wemagetsi, iyo goridhe - cyanide yakaoma anions, senge zvidimbu zvine gwara chairo, inoenda kune cathode imwe neimwe. Pavanosvika pane cathode pamusoro, ivo vanowana nyore maerekitironi uye vanopinda maitiro ekuderedza. Iyi nzira inogona kunyatsotsanangurwa neiyo Electrode reaction fomura: Au(CN)_2^-+e^- = Au + 2CN^-. Ioni dzegoridhe dzakabudirira "kushandurwa" kuita elemental goridhe, iyo zvishoma nezvishoma inoisa pane cathode, sekunge iri kunyora nyaya yegoridhe genesis. Zvichakadaro, pane anode, cyanide ions inorasikirwa nemaerekitironi uye inosangana neiyo oxidation reaction, senge. 2CN^--2e^-=(CN)_2â†. Nekudaro, iyi yedivi rekuita inofanirwa kunyatsodzorwa mukati meiyo electrolysis maitiro kudzivirira chero kukanganisa kunokanganisa pakubvisa uye kuchena kwegoridhe.

II. Maitiro Emaitiro: Kugarisana kweZvakanakira uye Zvinetso

(I) Zvinozivikanwa Zvakanakira

1.Streamlined Process for High Efficiency

Nzira dzechinyakare dzekubvisa goridhe, dzakadai senzira yekutsiva zinc - guruva uye nzira yakabatidzwa - kabhoni Nzira yekunyudza goridhe, inowanzo sanganisira nzira dzakasiyana-siyana dzakaoma - kupatsanurwa kwemvura, kutsiva zinc - guruva, kana nzira dzekunyudza goridhe uye kubvisa goridhe. Kusiyana neizvi, kuburitsa goridhe zvakananga nemagetsi kunoita kuti maitiro aya ave nyore. Hapana chikonzero chekushandisa nguva yakawanda nesimba pamatanho aya epakati, izvo zvinongochengetedza nguva inokosha chete asiwo zvinoderedza mari inoshandiswa mumidziyo, zvichiita kuti maitiro ekubvisa goridhe ave mapfupi uye anoshanda.

2.Kuvimbiswa Kwepamusoro Kudzorera Matengo

Nekuda kweiyo yakasarudzika electrolysis musimboti, iyi tekinoroji inogona kubvisa goridhe kubva kucyanide - leaching ane nhumbu mhinduro kusvika kuzere. Pasi pemamiriro ekugadzirisa zvakanaka, iyo goridhe Kudzorera mwero kazhinji inogona kusvika pamwero unogutsa. Semuyenzaniso, mushure mekunge Jiangxi Jinshan Gold Mine yatora maitiro matsva ekubvisa goridhe, huwandu hwekudzoreredza goridhe hwakawedzera zvakanyanya, zvichiunza hupfumi hwakanyanya kubhizinesi.

3.Kugadzirwa kwePamusoro - Kuchena Zvigadzirwa

Munguva ye electrolysis maitiro, mamwe akawanda esimbi asina kuchena ayoni anobviswa zvinobudirira kubva pakuisa pane cathode. Izvi zvinoguma nepamusoro - kuchena kwegoridhe, kudzikisa zvakanyanya mutoro weanotevera ekunatsa maitiro, ayo anogona kuonekwa seaviri - kune - imwe mukana.

4.Implementation of a Relatively Environmental - Friendly Concept

Zvichienzaniswa nezvinobvira nyaya dzezvakatipoteredza, dzakadai seheavy - simbi kusvibiswa, yakabatana ne zinc - guruva kutsiva nzira, iyo yakananga electrolysis nzira, kana yakanyatsodzorwa, inonyanya kushamwaridzana, ichipa nzira inogoneka yekusimudzira kwakasimba kweindasitiri yemigodhi.

(II) Matambudziko Akasangana nawo

1.Zvakaoma Zvinodiwa kune Pregnant Solution Quality

Cyanide - leaching pamuviri mhinduro ndiyo "raw material" ye electrolytic goridhe kudhirowa "kuedza," uye hunhu hwayo hwakakosha zvakanyanya. Kusiyanisa kudiki kwemaparamendi akadai sekusachena kwemukati, goridhe kusungirirwa, uye pH kukosha mune nhumbu mhinduro inogona kuve nemhedzisiro yakakura pane electrolysis maitiro. Naizvozvo, kusati kwaitwa electrolysis, mushonga wepamuviri unofanirwa kuve wakanyatso kucheneswa kuti ubvise "zvinopindira zvinhu" zvakaita semhangura, zinc, iron, uye mamwe maion simbi, pamwe neakamiswa simbi, kuve nechokwadi chekufambira mberi kwakanaka kweiyo electrolysis process.

2.Mutengo weKudzvinyirirwa nekuda kweKushandiswa kweMasimba Makuru

Iyo electrolysis process isimba - rakasimba, rinoda huwandu hukuru hwesimba remagetsi. Izvi pasina mubvunzo zvinowedzera mari yekugadzira. Mumamiriro ezvinhu emazuva ano ekukwira kwemitengo yemagetsi, kutsvaga nzira dzekuderedza kushandiswa kwesimba rave dambudziko rinokurumidza kugadziriswa.

3.High - Threshold Equipment Investment

Kuti uwane yakananga electrolytic kudhirowa kwegoridhe, akasarudzika emagetsi maseru, magetsi emagetsi ekushandisa, electrode zvinhu, nezvimwewo, zvinofanirwa kuve nemidziyo. Mari yekutanga yekudyara yezvimedu zvemidziyo iyi yakakwira zvakanyanya, zvichiunza chipingamupinyi chakakosha kune mamwe mabhizinesi ane zviwanikwa zvemari zvakati wandei.

4.Zvinogona Kuchengetedza Ngozi

Zvinofanira kusimbiswa kuti cyanide - leaching pamuviri mhinduro ine chepfu. Munguva yemaitiro e electrolysis, kunyangwe kakanganiso kadiki kekushandisa kunogona kutungamira kunjodzi dzakakomba dzekuchengetedza dzakadai secyanide leakage, zvichikonzera kukuvadza kukuru kune vese vashandi uye nharaunda.

III. Kufurira Zvinhu: Key Elements mu Multiple Dimensions

(I) Kusarudzwa kweElectrode Materials

Kuita kwezvinhu zvecathode kwakakosha kune goridhe deposition mhedzisiro uye kugona kwazvino, senge sarudzo yemumhanyi yeshangu dzekumhanya. Zvakajairwa cathode zvinhu zvakaita sesimbi isina tsvina uye titanium zvine zvayakanakira nezvayakaipira uye zvinoda kunyatsosarudzwa zvinoenderana nemamiriro chaiwo. Iyo anode material inofanirwa kuve neyakanaka magetsi conductivity uye yakanakisa corrosion resistance. Titanium - plated platinum electrodes uye mamwe maitiro akafanana akakodzera kuti ave nechokwadi chekushanda kwakagadzikana munzvimbo yakaoma ye electrolysis.

(II) Mutemo weElectrolysis Parameters

Electrolysis parameters senge yazvino density, electrolysis nguva, tembiricha, uye kubvongodza kumhanya kwakafanana ne "control knobs" ye electrolysis process. Yakakodzera ikozvino density inogona kumhanyisa mwero wekuisa goridhe, asi kana yakanyanya kukwirira, maitiro epadivi achaitika, zvichideredza kushanda kwazvino. Iyo nguva ye electrolysis inoda kunyatsotemwa zvichibva pane yegoridhe yemukati mune nhumbu mhinduro uye mamiriro e electrolysis kuti ive nechokwadi chekutorwa kwegoridhe rakazara. Kazhinji, kuwedzera kwekushisa kunofambisa kuparara uye kuiswa kwegoridhe, asi kana yakanyanyisa, zvinotungamirira mukukwira kwakanyanya kwekushandiswa kwesimba uye kuwedzera kuparara kwekurasikirwa kwecyanide. Kukurudzira kwakakodzera kunogona kugovera zvakaenzana maion mumhinduro uye kuwedzera kugona kwe electrolysis.

(III) Kufurira Kwepamuviri Kugadzirisa Kuumbwa

Kunze kweiyo yekutanga goridhe - cyanide complex ion, mamwe maion mumhinduro ine pamuviri anoitawo basa rakakosha mukuita kwekubvisa goridhe. Kana iyo concentration ye CN^- yakanyanya kuderera, iyo goridhe - cyanide complex ion inogona kuparadzanisa, inokanganisa goridhe deposition. Kana iyo concentration ye OH...- yakanyanya kuwanda, inoderedza kunyungudika kwegoridhe. Ioni dzisina kuchena dzinowanzoisa zvakanaka pane cathode kana kuita negoridhe - cyanide complex ion, zvichikanganisa mafambiro akajairika ekutorwa kwegoridhe.

IV. Mienzaniso Yekushandisa: Kuratidzira Kwekubudirira Mukuita

Iko Kubudirira Chiitiko cheJiangxi Jinshan Gold Mine

Kwemakore, Jiangxi Jinshan Gold Mine yakatora zvakasimba nzira itsva ye electrowinning yekutorwa kwegoridhe. Ichi chiyero hachina kungorerutsa zvakanyanya kuyerera kwemaitiro asi chakabudirira kuwedzera huwandu hwese hwekudzoreredza goridhe kusvika pakakwirira patsva. Saizvozvo, mutengo wekugadzira goridhe wakadzikiswa nezvikamu makumi matatu kubva muzana - 30%, zvichiunza pundutso huru muupfumi kumugodhi uye zvichipa muenzaniso wekuparidzirwa nekushandiswa kwehunyanzvi uhu.

The Proactive Endeavor yeZhuji Gold Mine

Kubva muna Kubvumbi 1988. Zhuji Gold Mine yakashinga kushandisa direct electrowinning kubvisa bullion kubva mucyanide - leached carbon slurry. Kuburikidza nekuedza kunoshanda, mibairo yakanaka yakawanwa, uye mabhenefiti akati wandei akawanikwa, achipa ruzivo rwakakosha rwekutarisa kune vamwe vayo.

Tekinoroji yekubvisa yakananga electrolytic kubviswa kwegoridhe kubva kucyanide - leaching ane nhumbu mhinduro, kunyangwe yakatarisana nematambudziko mazhinji, iri kupinza hutsva hutsva mukusimudzira indasitiri yemigodhi yegoridhe nemabhenefiti ayo akasiyana uye tarisiro yakakura yekushandisa. Nekuenderera mberi kwetekinoroji uye kuvandudzwa, zvinotendwa kuti tekinoroji iyi ichapenya zvakanyanya mune ramangwana remunda wekuchera goridhe.
