Sei Sodium Cyanide Ichishandiswa Zvakawanda Mukuchera Goridhe?

Munyaya yekubvisa goridhe , sodium cyanide inomira sechinhu chakakosha muindasitiri iyi. Asi chii chinoita kuti ive chinhu chakakosha kudaro? Ngationgororei zvikonzero zvekushandiswa kwayo zvakanyanya.

1. Chemical Reactivity

Kubudirira kweSodium cyanide mukubvisa goridhe kunonyanya kukonzerwa nehunyanzvi hwayo hwemakemikari. Goridhe, muchimiro chayo chekare, harina simba uye harikurumidzi kupindura nezvinhu zvakajairika. Zvisinei, kana Sodium Cyanide ikaiswa mukugadzirwa kwekubvisa, inopindura negoridhe paine okisijeni nemvura kuti igadzire soluble gold-cyanide compound. Kuita uku kunoshandura zvidimbu zvegoridhe zvisinganyunguduke kuita soluble state, zvichiita kuti zvive nyore kuparadzaniswa kubva mu ore matrix. Kukwanisa uku kugadzira makemikari akagadzikana uye anonyunguduka negoridhe chinhu chakakosha mukushandiswa kwakanyanya kweSodium cyanide mukuchera goridhe.

2. Kubudirira uye Kuchena

Chimwe chezvakanakira zvikuru zvekushandisa sodium cyanide mukubvisa goridhe ndechekuti inoshanda zvakanyanya. Kubvisa cyanide kunogona kuita kuti goridhe ridzoke zvakanyanya, kazhinji kacho kuchiburitsa goridhe rinosvika 90% kana kupfuura riri mudombo, zvichienderana nehunhu hwedombo racho. Zvichienzaniswa nedzimwe nzira dzekubvisa, dzakadai seMERCURY amalgamation , kubvisa cyanide kunoshanda zvakanyanya mukubvisa goridhe kubva mumhando dzakasiyana dzedombo, kusanganisira dombo remhando yepasi.

Zvakare, iyo goridhe-cyanide komboni yakaumbwa panguva yeleaching process inogona kufambiswazve kuti iwane yakakwirira-yakachena goridhe. Kuburikidza nematanho anotevera senge kunaya ne zinc kana electrolysis, goridhe rinogona kudzoserwa munzvimbo yakachena, richisangana nemhando yepamusoro zvinodiwa zvezvishongo, zvemagetsi, uye misika yekudyara.

3. Mutengo - kubudirira

Kubva pamaonero ehupfumi, sodium cyanide inopa mutengo - kushanda. Kunyangwe sodium cyanide pachayo iri muchetura, kugadzirwa kwayo uye mutengo wekutenga zvine hungwaru kana uchienzaniswa nemamwe mareagents anogona kushandiswa kuchera goridhe. Pamusoro pezvo, iyo cyanidation process yakanyatso kusimbiswa uye yakagadziridzwa kwemakumi emakore. Zvivakwa nemidziyo inodiwa pa cyanide leaching yakamisikidzwa, ichideredza kudiwa kweinodhura, yakasarudzika tekinoroji. Izvi zvinoreva kuti makambani emigodhi anokwanisa kuchera goridhe zvine mutsindo nemutengo wakaderera pachikamu chimwe chete chegoridhe rinogadzirwa, zvichiita kuti ive sarudzo inokwezva muindasitiri ine makwikwi ekuchera goridhe.

4. Yakasimbiswa Infrastructure uye Kuzivikanwa

Indasitiri yemigodhi yegoridhe yave ichishandisa sodium cyanide pakuchera goridhe kweanopfuura zana. Nekuda kweizvozvo, kune tsime-yakagadziridzwa zvivakwa zvakatenderedza kushandiswa kwe sodium cyanide. Makambani emigodhi ane mukana kune yakavimbika yekugovera cheni ye sodium cyanide, kubva mukugadzirwa kusvika pakutakura uye kuchengetedza.

Uyezve, mainjiniya emigodhi, matekinoroji, uye vashandi vanonyatsoziva maitiro ecyanidation. Ivo vakadzidziswa kubata sodium cyanide zvakachengeteka, kushandisa iyo leaching michina, uye kutonga iyo yakazara yekubvisa maitiro. Iri ruzivo rwakaunganidzirwa uye unyanzvi hunoita kuti zvive nyore kumabasa emigodhi kuti aite uye achengetedze maitiro ecyanidation, kuderedza kudzidzira kwekudzidzira uye njodzi dzinogona kuitika dzine chokuita nekutora nzira itsva uye dzisina kuedzwa dzekuchera.

5. Kuchinjika kune Mhando Dzakasiyana Ore

Sodium cyanide - yakavakirwa nzira dzekubvisa dzinochinjika zvakanyanya kune dzakasiyana siyana dzegoridhe ore mhando. Kunyangwe iri yemahara - milling ores uko goridhe rinosununguka zviri nyore kubva padombo rekugamuchira, kana mamwe akaomarara erefractory ores anoda mamwe matanho ekutanga ekugadzirisa, cyanide leaching inogona kugadziridzwa uye kugadziridzwa. Kune refractory ores, nzira dzakaita sekugocha, kudzvanywa oxidation, kana bio-oxidation inogona kusanganiswa necyanide leaching kuputsa ore chimiro uye kuburitsa goridhe kune cyanide mhinduro, zvichiita kuti ibudise inoshanda. Izvi zvakasiyana-siyana zvinoita kuti sodium cyanide ive sarudzo inosarudzika kumakambani emigodhi anobata neakasiyana ore deposits.

Nekudaro, zvakakosha kuti uzive kuti nepo sodium cyanide ichipa zvakakosha mukutora goridhe, kushandiswa kwayo kunosimudza zvakakomba kwezvakatipoteredza nekuchengetedza kunetseka nekuda kwehupfu hwayo. Nekuda kweizvozvo, indasitiri inogara ichitsvaga nekugadzira dzimwe nzira dzekubvisa uye kuvandudza mapuroteni ekuchengetedza kudzikisa njodzi dzine chekuita nekushandiswa kwesodium cyanide ichiri kusangana nepasi rose kudiwa kwegoridhe.
