Zvakanakira uye Zvakaipa zveSodium Cyanide muGoridhe Leaching

Muindasitiri yekuchera goridhe, maitiro ekubvisa goridhe akakosha zvikuru. Sodium cyanide yagara iri chinhu chakakosha mukuita kwekubvisa goridhe . Kunzwisisa zvakanakira nekuipira kwayo kwakakosha kune vese vanochera goridhe nevanochengetedza nharaunda, sezvo ichibatsira mukuita sarudzo dzakangwara nezvekuramba ichishandiswa uye mukutsvaga dzimwe nzira.

1. Zvakanakira Sodium Cyanide muGoridhe Leaching

Kubudirira Kwepamusoro muKuparara Kwegoridhe

Imwe yemabhenefiti akakosha eiyo

Dum Cyanide mu gold leaching ndiyo nzira yayo yepamusoro yekunyungudutsa goridhe. Maion e Cyanide anogadzira complexes dzakagadzikana nemaion e gold. Izvi zvinobvumira kuburitswa kwegoridhe kubva mumatombo asina kunyanya kuderera. Maitiro emakemikari pakati pegoridhe, oxygen, uye sodium cyanide mumvura 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 zvishoma kana tichienzanisa nedzimwe nzira dzekubvisa tsvina. Maitiro ayo ekugadzira akajairika, uye anowanikwa zviri nyore muhuwandu hwakawanda. Makambani emigodhi anogona kutenga Sodium Cyanide nemutengo wakakodzera, izvo zvakakosha kuti purofiti irambe iripo, kunyanya kana ichishanda nemabasa makuru. Pamusoro pezvo, michina iri nyore inodiwa pakubvisa tsvina yecyanide inoderedzawo 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

Dambudziko guru reSodium cyanide nderekuti ine chepfu yakanyanya. Cyanide inouraya zvikuru zvipenyu zvemumvura, shiri, nemhuka dzinoyamwisa. Kana cyanide ikadururwa panzvimbo yekuchera, inogona kusvibisa mvura iri pedyo, zvichikonzera kufa kwehove nezvimwe zvipenyu zvemumvura. Kunyangwe huwandu hushoma hwecyanide mumvura hunogona kukanganisa nharaunda yese. Semuenzaniso, cyanide inogona kukanganisa kushanda kwe cytochrome c oxidase mumasero, ichidzivirira kushandiswa kweokisijeni kwakajairika mukufema kwemhepo.

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.
