Zvakanakira uye Zvakaipa zveSodium Cyanide muGoridhe Leaching

Muindasitiri yemigodhi yegoridhe, maitiro e kutorwa kwegoridhe inokosha zvikuru. Sodium cyanide yave kwenguva refu iri kiyi reagent mu goridhe richidonha process. Kunzwisisa zvakanakira nekuipira kwairi kwakakosha kune vese varimi vemigodhi nevanoona nezvezvakatipoteredza, sezvo zvichibatsira mukuita sarudzo dzine ruzivo pamusoro pekuenderera kwayo kushandiswa uye mukutsvaga dzimwe nzira.

1. Zvakanakira Sodium Cyanide muGoridhe Leaching

Kubudirira Kwepamusoro muKuparara Kwegoridhe

Imwe yemabhenefiti akakosha eiyo

dum cyanide mugoridhe leaching ndiko kugona kwayo kukuru mukunyungudutsa goridhe. Cyanide ions inoumba macomplexes akatsiga ane maion egoridhe. Izvi zvinobvumira kutorwa kwegoridhe kubva kunyange pasi-giredhi ores. Iko kuita kwemakemikari pakati pegoridhe, oksijeni, uye sodium cyanide mune aqueous solution inogona kumiririrwa se:

4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH. Kuita uku kunoita kuti goridhe rikwanise kutorwa zvakakwana, zvichiita kuti goho rive rakakura kubva mumatombo anocherwa.

Mutengo - Kubudirira

Sodium cyanide inodhura - inoshanda kana ichienzaniswa neakawanda mamwe maitiro ekuleaching. Kugadzirwa kwayo kwakanyatso kusimbiswa, uye inowanikwa nyore muhuwandu hwakawanda. Makambani emigodhi anogona kutenga Sodium Cyanide pamutengo unonzwisisika, izvo zvakakosha pakuchengetedza purofiti, kunyanya kana uchibata nemabasa makuru. Pamusoro pezvo, iyo iri nyore michina inodiwa kune cyanide leaching process inowedzera kuderedza mitengo.

Kuenderana neAkasiyana Ore Type

Sodium cyanide inogona kushandiswa nehupamhi hwegoridhe - inotakura ores. Kunyangwe iyo ore ndeyemahara - kugaya kana ine yakaoma sulfide zvicherwa, cyanide leaching inowanzo gadziridzwa kuburitsa goridhe. Uku kuchinjika kunoita kuti ive sarudzo inosarudzika kune akawanda mabasa emigodhi pasi rese, sezvo ichideredza kudiwa kweore inodhura - chaiyo yekugadzirisa maitiro.

2. Kuipa kweSodium Cyanide muGoridhe Leaching

Njodzi dzezvakatipoteredza

Iyo inonyanya kukosha drawback ye Sodium cyanide ndiyo huturu hwayo hwakanyanyisa. Cyanide inouraya zvakanyanya kuhupenyu hwemumvura, shiri, uye mhuka dzinoyamwisa. Muchiitiko chekuteuka kwecyanide panzvimbo yemugodhi, inogona kusvibisa zvitubu zvemvura zviri pedyo, zvichikonzera kufa kwehove nezvimwe zvipenyu zvemumvura. Kunyangwe zvidiki zve cyanide mumvura zvinogona kukanganisa zvisikwa zvese. Semuenzaniso, cyanide inogona kuvharidzira basa re cytochrome c oxidase mumasero, kudzivirira kushandiswa kwakajairika kweokisijeni mukufema kweaerobic.

Zvakasimba Regulatory Zvinodiwa

Nekuda kwehupfu hwayo, kushandiswa kwesodium cyanide mumigodhi yegoridhe kunoenderana nemirairo yakasimba. Makambani emigodhi anofanirwa kuisa mari mumasistimu emarara ekuchengetedza marara kudzivirira cyanide kupinda nharaunda. Vanofanira kuita zvirongwa zvekuongorora kuti vaone kuti mazinga ecyanide mumvura nemhepo ari mukati memiganhu inogamuchirwa. Izvi zvinodikanwa zvekutonga zvinowedzera mari yekushanda kwemakambani emigodhi, sezvo achifanira kugovera zviwanikwa kuti atevedzere mirau.

Njodzi dzehutano kune Vashandi

Vashandi vane chekuita negoridhe leaching process vachishandisa sodium cyanide vari panjodzi yekufumurwa. Kufema kana kubata ganda necyanide kunogona kukonzera matambudziko akakomba ehutano, kusanganisira kutemwa nemusoro, dzungu, kuda kurutsa, uye muzviitiko zvakanyanya kufa. Makambani emigodhi anofanirwa kupa kudzidziswa kwakawanda kwekuchengetedza uye zvekuzvidzivirira nazvo kune vashandi vavo kuti vaderedze njodzi idzi. Zvisinei, njodzi dzinogona kuitika, dzichiisa upenyu hwevashandi panjodzi.

Mukupedzisa, sodium cyanide inopa mabhenefiti akasiyana maererano nekushanda, mutengo - kushanda, uye kuenderana kweore mukuita kwegoridhe leaching. Nekudaro, njodzi dzayo dzezvakatipoteredza, zvinotemerwa zvemitemo, uye njodzi kune hutano hwevashandi hazvigone kufuratirwa. Sezvo indasitiri yezvicherwa ichienda kumberi, pane kudiwa kuri kukura kwekugadzira dzimwe nzira dzekudzidzira dzinoenderana nemhoteredzo uye dzinoshanda mune zvehupfumi, uku ichichengetedza yakakwirira-yemhando yekuchera miitiro yave kuwanikwa nesodium cyanide.
