Cyanide-Yemahara Goridhe Kuchera: Kumbundira Greener Alternatives

ziviso

Kubviswa kwegoridhe kwagara kuri indasitiri yakakosha, asi nzira yechinyakare ichitsamira Sodium cyanide yamutsa zvinetso zvakakomba zvemhoteredzo uye utano. Sodium cyanide ine muchetura zvakanyanya uye inogona kukonzera kukuvadzwa kukuru kune ecosystem kana isina kunyatsogadziriswa. Mumakore achangopfuura, kwave nekusundidzira kuri kukura kwekugadzira dzimwe nzira, dzakasimba nzira dze Kuchera goridhe. Iyi blog positi inoongorora idzi nzira itsva dzinopa nzira ine hushamwari kwezvakatipoteredza kune zera-kare maitiro ekutora goridhe.

Dambudziko neSodium Cyanide muKuchera Goridhe

Sodium cyanide yanga iri iyo yekuenda-kuenda kune reagent yekuchera goridhe kweanopfuura zana nekuda kwekubudirira kwayo mukunyungudutsa goridhe kubva mumatombo. Zvisinei, huturu hwayo idambudziko guru. Kunyange mudiki, cyanide inogona kuuraya zvipenyu zvemumvura, shiri, uye mhuka dzinoyamwisa. Muchiitiko chekurasa kana kuraswa zvisina kunaka mumabasa emigodhi, cyanide inogona kusvibisa zvitubu zvemvura, ivhu, nemhepo, zvichitungamira mukushatisa kwezvakatipoteredza kwenguva refu. Pamusoro pezvo, kubata kwecyanide kunoda matanho akasimba ekuchengetedza, uye chero kupera kunogona kukonzera kukuvadza kune vashandi.

Kuvimbisa Green Alternatives kune Sodium Cyanide

1. Bioleaching

Bioleaching, inozivikanwawo se microbial leaching, inzira inoshandisa tupukanana kubvisa simbi kubva musimbi. Panyaya yekutorwa kwegoridhe, mamwe mabhakitiriya, akadai saThiobacillus ferrooxidans, anogona kuokisisa sarufa - inotakura zvicherwa zvine chekuita negoridhe, ichiburitsa goridhe nenzira inosvikika. Iyi nzira inoenderana nenharaunda sezvo isingashandisi makemikari ane chepfu secyanide. Inoshandawo panguva yakadzikama tembiricha uye kumanikidzwa, ichideredza kushandiswa kwesimba zvichienzaniswa nedzimwe nzira dzechinyakare dzekubvisa. Bioleaching isarudzo yakagadzikana inogona kushandiswa kune yakaderera-giredhi ores, ayo anowanzo asina hupfumi kugadzirisa uchishandisa akajairwa matekiniki.

2. Thiosulfate Leaching

Thiosulfate leaching ndiyo imwe nzira kune cyanide - based extraction. Inoshandisa thiosulfate ions, kazhinji iri muchimiro chesodium thiosulfate, kuomesa negoridhe nekuinyungudutsa kubva musimbi. Iyi nzira haina muchetura zvishoma pane cyanide. Thiosulfate yakagadzikana munharaunda uye haiunzi yakakwira - njodzi yekutyisidzira mhuka dzesango nemvura. Uyezve, Thiosulfate leaching inogona kunyatsoshanda mune mamwe marudzi e ores, kunyanya ayo ane mhangura uye mamwe masimbi anogona kukanganisa cyanide - based process. Iyo nzira inogona zvakare kugadziridzwa kuderedza kushandiswa kwemakemikari uye kugadzirisa goridhe kudzoreredza mitengo.

3. Ionic Liquids

Ionic zvinwiwa munyu uri mvura patembiricha yekamuri. Vane zvinhu zvakasiyana-siyana zvinoita kuti zvive zvakakodzera kutorwa kwegoridhe. Ionic zvinwiwa zvinogona kunyungudutsa goridhe kubva kune ore pasina kudiwa kwemakemikari ane muchetura. Ivo havasi - volatile, izvo zvinoreva kuti havabatsire mukusvibiswa kwemhepo panguva yekubvisa. Pamusoro pezvo, anogona kudzokororwa uye kushandiswazve, kuderedza kugadzirwa kwemarara. Kunyangwe ichiri muchikamu chekutsvagisa nekusimudzira chekushandisa kwakakura, zvinwiwa zveionic zvinoratidza kugona kukuru seimwe nzira inogoneka kune yechinyakare nzira dzekuchera goridhe.

4. Supercritical Fluid Extraction

Kubvisa mvura inokonzereswa ne supercritical kunoshandisa supercritical fluids, senge kabhoni dioxide (CO₂) pakupisa kwakanyanya uye kumanikidzwa, kuti ibudise goridhe kubva muore. Painenge iri supercritical, CO₂ ine hunhu huri pakati pegasi nemvura, zvichiita kuti ipinde muore uye inyungudise goridhe. Nzira iyi haikuvadzi nharaunda sezvo CO₂ iri compound isina chepfu uye yakawanda. Inoderedzawo kudiwa kwemvura yakawanda nemamwe makemikari anoshandiswa mukubvisa goridhe kwechinyakare. Kubvisa supercritical fluid kunogona kuva nzira inoshanda zvikuru yekubvisa goridhe, kunyanya kubva muore dzakaoma.

Matambudziko uye Nzira Iri Mberi

Nepo idzi dzimwe nzira dzinoratidza vimbiso huru, pachine matambudziko ekukunda. Semuyenzaniso, Bioleaching inogona kuita inononoka, uye kugadzirisa mamiriro ekukura kwema microorganisms anogona kuve akaoma. Thiosulfate leaching ingangoda kuomarara maitiro ekudzora zvichienzaniswa necyanide leaching. Ionic zvinwiwa uye supercritical fluid kudhirowa zvichiri mumatanho ekutanga ebudiriro yekutengeserana, uye kune mitengo inodyidzana nekuwedzera aya matekinoroji. Nekudaro, nekuenderera mberi nekutsvagisa nekusimudzira, matambudziko aya anogona kugadziriswa. Hurumende, makambani emigodhi, uye masangano ekutsvagisa anofanira kubatana kuti aise mari mukusimudzira nekushandisa nzira idzi dzekuchera goridhe dzakasvibirira. Izvi hazvingobatsiri kuchengetedza zvakatipoteredza asiwo kuona kuti indasitiri yezvicherwa zvegoridhe inogara kwenguva refu.

Mukupedzisa, kutsvaga kune dzimwe nzira dzekuita Sodium Cyanide mukuchera goridhe haisi nyaya yebasa rezvakatipoteredza chete asiwo mukana wekuvandudza nekusimudzira. Nekugamuchira tekinoroji idzi dzakasvibirira, indasitiri yezvicherwa zvegoridhe inogona kudzikisa tsoka yayo yezvakatipoteredza uye kubatsira kune ramangwana rakagadzikana.
