Kugwiritsa Ntchito Maukadaulo a Sodium Cyanide Replacement Technologies mu Migodi Yaing'ono

Introduction

Mu makampani opanga migodi, makamaka ku Migodi Yaing'ono , kukumba zitsulo zamtengo wapatali monga golide ndi siliva kwakhala kudalira Sodium Cyanide kwa nthawi yayitali . Komabe, kugwiritsa ntchito sodium cyanide kumabweretsa nkhawa zazikulu pazachilengedwe komanso chitetezo. Ndi poizoni kwambiri ndipo kungayambitse kuipitsa madzi kwambiri komanso kuvulaza zamoyo zam'madzi. Chifukwa cha kulimbikira kwambiri kuteteza chilengedwe komanso malamulo okhwima padziko lonse lapansi, migodi yaying'ono ili pansi pa kukakamizidwa kwakukulu kuti ipeze njira zina zokopera zitsulo. Nkhaniyi ikufotokoza momwe Sodium cyanide Replacement Technologie imagwiritsidwira ntchito m'migodi yaying'ono, cholinga chake ndi kupereka kumvetsetsa kwathunthu kwa mayankho okhazikika awa.

Zoyipa za Sodium Cyanide mu Migodi Yaing'ono

Zowopsa Zachilengedwe

Migodi ing'onoing'ono nthawi zambiri imakhala ndi njira zamakono zoyendetsera zinyalala. Mukagwiritsa ntchito sodium cyanide , pamakhala chiopsezo chachikulu cha kutayikira kwa cyanide m'madzi apafupi panthawi yotulutsa. Ngakhale kuchuluka kochepa kwa cyanide kungakhale kovulaza kwambiri chilengedwe. Mwachitsanzo, kungayambitse kufa kwa nsomba ndi zamoyo zina zam'madzi, kusokoneza unyolo wonse wa chakudya cha m'madzi. Kuphatikiza apo, cyanide imatha kukhalabe m'chilengedwe kwa nthawi yayitali, zomwe zimapangitsa kuti nthaka ndi madzi ziwonongeke kwa nthawi yayitali.

Zoopsa Zachitetezo

Kusamalira sodium cyanide kumafuna njira zotetezera. Migodi yaing'ono nthawi zonse sangakhale ndi ndalama zogulira zida zoyenera zotetezera ndi kuphunzitsa antchito awo. Kukumana mwangozi ndi sodium cyanide kungayambitse mavuto aakulu azaumoyo kwa ogwira ntchito m'migodi, kuphatikizapo kulephera kupuma komanso imfa. Komanso, pakagwa masoka achilengedwe kapena ngozi, kusungidwa ndi kunyamula kwa sodium cyanide m'migodi yaing'ono kumatha kukhala pachiwopsezo chachikulu kwa madera ozungulira.

Njira Zamakono Zopangira Sodium Cyanide

Thiosulfate Leaching

Thiosulfate leaching ndi njira ina yopanda poizoni m'malo mwa cyanide-based based extraction. Amagwiritsa ntchito ayoni a thiosulfate kusungunula golide ku ores. Njirayi ndi yabwino kwambiri kuwononga chilengedwe chifukwa sichitulutsa zinthu zoopsa kwambiri. M'migodi yaing'ono, thiosulfate leaching ikhoza kukhala njira yabwino chifukwa ingagwiritsidwe ntchito pamitundu yosiyanasiyana ya ore. Komabe, ili ndi zovuta zina. Zingafune kukhathamiritsa kowonjezera, monga kuwongolera pH ndi kutentha kwa yankho la leaching molondola. Komanso, ndalama zogwirira ntchito ndizokwera kwambiri poyerekeza ndi leaching ya cyanide, makamaka chifukwa cha mtengo wa thiosulfate reagents komanso kufunikira kwa zida zovuta kwambiri nthawi zina.

Kuchuluka kwa Chloride

Chloride leaching imaphatikizapo kugwiritsa ntchito ayoni a kloride kusungunula golide ndi zitsulo zina kuchokera ku ores. Zimapereka zoopsa zochepa zachilengedwe poyerekeza ndi cyanide. Migodi yaing'ono ingapindule ndi njirayi chifukwa imatha kusinthasintha malinga ndi momwe zinthu zilili m'deralo. Mwachitsanzo, m'malo omwe chloride - okhala ndi zinthu zopezeka mosavuta, mtengo wa reagents ukhoza kuchepetsedwa. Komabe, kuyang'anira zopangira ndi zinyalala zochokera ku chloride leaching kungakhale kovuta. Chloride - zinyalala zolemera zingafunike chisamaliro chapadera kuti tipewe dzimbiri ndi kuwonongeka kwa chilengedwe.

Bioleaching

Bioleaching imagwiritsa ntchito tizilombo toyambitsa matenda kuchotsa zitsulo kuchokera ku ores. Iyi ndi njira yokhazikika komanso yothandiza zachilengedwe. Tizilombo tating'onoting'ono, monga mabakiteriya ena, amatha kuphwanya miyala ndi kutulutsa zitsulozo. Kwa migodi yaing'ono, bioleaching ili ndi mwayi wokhala wosavuta kukhazikitsa nthawi zina. Sichifuna zida zapamwamba kwambiri. Komabe, mphamvu ya bioleaching ikhoza kuchepetsedwa ndi zinthu monga mtundu wa ore ndi ntchito za tizilombo toyambitsa matenda. Ma ore ena sangawonongeke mosavuta ndi tizilombo tating'onoting'ono, ndipo kukula ndi ntchito za tizilombo toyambitsa matenda zimatha kukhudzidwa ndi chilengedwe monga kutentha ndi pH.

Kugwiritsa Ntchito Chilengedwe - Othandizira Ovala Golide ochezeka

Pali zinthu zingapo zoyeretsera golide zomwe zimapezeka pamsika zomwe zingalowe m'malo mwa sodium cyanide. Mwachitsanzo, chinthu choyeretsera golide chomwe chimapangidwa ndi Guangxi Senhe High - tech Co., Ltd. chili ndi ubwino wa poizoni wochepa, kuchira mwachangu, komanso kugwiritsa ntchito mosavuta. Zinthuzi zitha kugwiritsidwa ntchito m'njira zomwezo monga sodium cyanide, monga kuyeretsa dziwe, kuyeretsa dziwe, ndi njira za Carbon -in-pulp. Zingathe kuchotsa golide kuchokera ku mitundu yosiyanasiyana ya miyala, kuphatikizapo yomwe ili ndi zinthu zovuta. Chitsanzo china ndi CNFREE sodium cyanide, yomwe ingagwiritsidwe ntchito mwachindunji poyeretsa golide popanda kusintha zida zoyambirira ndi njira yoyeretsera, kukwaniritsa cholinga choteteza chilengedwe chobiriwira.

Mavuto ndi Mayankho pa Kugwiritsa Ntchito Njira Zina Zamakono M'migodi Yaing'ono

Mtengo - kuchita bwino

Chimodzi mwazovuta zazikulu za migodi yaing'ono potengera umisiri wina ndi mtengo - kuchita bwino. Njira zina zambiri, monga thiosulfate leaching, zitha kukhala zokwera mtengo zoyambira pakugulitsa zida ndi ma reagents. Pofuna kuthana ndi izi, migodi yaing'ono ingalingalire kugwirizana ndi mabungwe ofufuza kapena makampani akuluakulu a migodi kuti agawane mtengo wa kafukufuku ndi chitukuko cha njira zotsika mtengo. Kuphatikiza apo, thandizo la boma kapena zolimbikitsira zitha kuperekedwa kuti zilimbikitse migodi yaing'ono kugwiritsa ntchito matekinoloje okhazikikawa.

Katswiri Waumisiri

Migodi ing'onoing'ono ingakhale yopanda ukadaulo wofunikira kuti ugwire ntchito ndi kukulitsa umisiri winawu. Mapulogalamu a maphunziro atha kukonzedwa ndi mabungwe amakampani kapena mabungwe aboma kuti aphunzitse ogwira ntchito ku migodi kugwiritsa ntchito moyenera njira zatsopano zakukumba. Mwachitsanzo, maphunziro amomwe mungayendetsere magawo mu thiosulfate leaching kapena momwe mungasamalire chilengedwe cha tizilombo toyambitsa matenda mu bioleaching. Kuphatikiza apo, opereka ukadaulo atha kupereka - chithandizo chaukadaulo pamalo kumigodi yaying'ono panthawi yoyambira kugwiritsa ntchito matekinoloje atsopano.

Kusintha kwadongosolo

Malo oyendetsera migodi akusintha nthawi zonse. Migodi ing'onoing'ono ikuyenera kuwonetsetsa kuti njira zina zopangira matekinoloje zomwe akugwiritsa ntchito zikugwirizana ndi malamulo a m'deralo ndi mayiko ena. Izi zimafuna kulankhulana kwambiri ndi olamulira. Mabungwe olamulira athanso kutengapo gawo popereka malangizo omveka bwino pamlingo wovomerezeka wa kukhudzidwa kwa chilengedwe ndi miyezo yachitetezo chaukadaulo wina, kupangitsa kuti migodi ing'onoing'ono ikhale yosavuta kusintha.

Kutsiliza

Kugwiritsa ntchito matekinoloje olowa m'malo mwa sodium cyanide m'migodi yaing'ono ndikofunikira kuti pakhale chitukuko chokhazikika pantchito yamigodi. Ngakhale pali zovuta monga mtengo - kuchita bwino, ukatswiri waukadaulo, ndi kusintha kwa malamulo, mapindu a umisiri wina wamakono pankhani yachitetezo cha chilengedwe ndi ofunikira. Pothana ndi mavutowa pogwiritsa ntchito mgwirizano, maphunziro, ndi kulankhulana bwino ndi akuluakulu oyang'anira, migodi yaing'ono imatha kusintha bwino kuti igwiritse ntchito njira zochepetsera zowonongeka, kuonetsetsa kuti ntchito zawo zikuyenda bwino komanso kuchepetsa zotsatira zake pa chilengedwe ndi anthu.
