Ubwino ndi Kuipa kwa Sodium Cyanide mu Leaching Gold

Mu makampani opanga golide, njira yochotsera golide ndi yofunika kwambiri. Sodium cyanide yakhala ikugwiritsidwa ntchito kwambiri pakuchotsa golide . Kumvetsetsa ubwino ndi kuipa kwake ndikofunikira kwa ogwira ntchito m'migodi komanso oteteza chilengedwe, chifukwa zimathandiza kupanga zisankho zolondola pankhani yopitiliza kugwiritsa ntchito golide komanso kufufuza njira zina.

1. Ubwino wa Sodium Cyanide mu Gold Leaching

Kuchita Bwino Kwambiri Pakutha kwa Golide

Chimodzi mwazabwino kwambiri za izi

Dum cyanide mu leaching ya golide ndi luso lake lalikulu pakusungunula golide. Ma ioni a Cyanide amapanga ma complexes okhazikika ndi ma ioni a golide. Izi zimathandiza kuti golide atulutsidwe ngakhale kuchokera ku miyala yotsika kwambiri. Machitidwe a mankhwala pakati pa golide, mpweya, ndi sodium cyanide mu yankho lamadzi amatha kuimiridwa motere:

4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH. Kuchita zimenezi kumapangitsa kuti golide achuluke kwambiri, zomwe zimachititsa kuti golide azikolola kwambiri.

Mtengo - Kuchita bwino

Sodium cyanide ndi yotsika mtengo poyerekeza ndi mankhwala ena ambiri ochotsera poizoni. Njira yake yopangira zinthu ndi yokhazikika, ndipo imapezeka mosavuta m'njira zambiri. Makampani opanga migodi amatha kugula Sodium Cyanide pamtengo wabwino, zomwe ndizofunikira kwambiri kuti phindu likhalebe, makamaka akamagwira ntchito zazikulu. Kuphatikiza apo, zida zosavuta zomwe zimafunikira pochotsa poizoni kuchokera ku cyanide zimachepetsanso ndalama.

Kugwirizana ndi Mitundu Yosiyanasiyana ya Ore

Sodium cyanide ingagwiritsidwe ntchito ndi mitundu yambiri ya golide - yokhala ndi ores. Kaya miyalayi ndi yaulere - mphero kapena imakhala ndi mchere wambiri wa sulfide, cyanide leaching imatha kukonzedwa kuti ichotse golide. Kusinthasintha kumeneku kumapangitsa kukhala chisankho chokondedwa kwa ntchito zambiri zamigodi padziko lonse lapansi, chifukwa zimachepetsa kufunika kwa miyala yamtengo wapatali - njira zina zopangira.

2. Kuipa kwa Sodium Cyanide mu Gold Leaching

Zowopsa Zachilengedwe

Vuto lalikulu la Sodium cyanide ndi poizoni wake woopsa kwambiri. Cyanide imapha kwambiri zamoyo zam'madzi, mbalame, ndi zinyama. Ngati cyanide yatayikira pamalo opangira migodi, imatha kuipitsa madzi apafupi, zomwe zimapangitsa kuti nsomba ndi zamoyo zina zam'madzi zife. Ngakhale cyanide yochepa m'madzi ingasokoneze chilengedwe chonse. Mwachitsanzo, cyanide imatha kuletsa ntchito ya cytochrome c oxidase m'maselo, kuletsa kugwiritsa ntchito mpweya wabwinobwino popuma.

Zofunikira Zowongolera Zolimba

Chifukwa cha kawopsedwe kake, kugwiritsa ntchito sodium cyanide mumigodi ya golide kumatsata malamulo okhwima. Makampani opanga migodi akuyenera kuyika ndalama zawo m'njira zowongolera zinyalala kuti cyanide isalowe m'malo. Ayenera kukhazikitsa mapulogalamu owonetsetsa kuti milingo ya cyanide m'madzi ndi mpweya ili m'malire ovomerezeka. Zofunikira zowongolera izi zimawonjezera ndalama zogwirira ntchito zamakampani amigodi, chifukwa amayenera kugawa zinthu kuti azitsatira malamulowo.

Ngozi Zaumoyo kwa Ogwira Ntchito

Ogwira nawo ntchito yotulutsa golide pogwiritsa ntchito sodium cyanide ali pachiwopsezo chowonekera. Kukoka mpweya kapena kukhudzana ndi khungu ndi cyanide kungayambitse matenda aakulu, kuphatikizapo mutu, chizungulire, nseru, ndipo nthawi zambiri, imfa. Makampani amigodi ayenera kupereka maphunziro ochuluka a chitetezo ndi zida zodzitetezera kwa ogwira ntchito awo kuti achepetse ngozizi. Komabe, ngozi zikhoza kuchitikabe, zomwe zingaike miyoyo ya ogwira ntchito pachiswe.

Pomaliza, sodium cyanide imapereka maubwino apadera pakuchita bwino, mtengo - magwiridwe antchito, komanso kuphatikizika kwa miyala yamtengo wapatali pakupanga golide. Komabe, kuopsa kwake kwa chilengedwe, malamulo okhwima okhwima, ndi zoopsa za thanzi la ogwira ntchito sizinganyalanyazidwe. Pamene ntchito ya migodi ikupita patsogolo, pakufunika kuti pakhale njira zina zochepetsera zowononga zachilengedwe komanso zothandiza pazachuma, kwinaku akusunga miyezo yapamwamba yochotsa zinthu zomwe zapezeka ndi sodium cyanide.
