Ubwino ndi Kuipa kwa Sodium Cyanide mu Leaching Gold

Mu migodi ya golide, ndondomeko ya kutulutsa golide ndizofunikira kwambiri. Sodium cyanide wakhala reagent yofunika mu kutulutsa golide ndondomeko. Kumvetsetsa ubwino ndi kuipa kwake ndikofunikira kwa onse ogwira ntchito ku migodi ndi zachilengedwe, chifukwa zimathandiza kupanga zisankho zomveka pakugwiritsa ntchito kwake ndikufufuza njira zina.

1. Ubwino wa Sodium Cyanide mu Gold Leaching

Kuchita Bwino Kwambiri Pakutha kwa Golide

Chimodzi mwazabwino kwambiri za izi

dum cyanide mu golide leaching ndikuchita bwino kwambiri pakusungunula golide. Ma cyanide ions amapanga zinthu zokhazikika zokhala ndi ayoni agolide. Zimenezi zimathandiza kuti m'zigawo golide ngakhale otsika kalasi. The Chemical reaction pakati pa golide, oxygen, ndi sodium cyanide mu njira yamadzimadzi akhoza 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 ndiyotsika mtengo - yogwira ntchito poyerekeza ndi njira zina zambiri zochotsera. Kapangidwe kake kamakhala kokhazikika, ndipo kamapezeka mosavuta pazambiri. Makampani amigodi akhoza kugula Sodium Cyanide pamtengo wokwanira, womwe ndi wofunikira kuti pakhale phindu, makamaka pochita ntchito zazikulu. Kuphatikiza apo, zida zosavuta zomwe zimafunikira pakuwotcha kwa 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

Chofunikira kwambiri drawback cha Sodium cyanide ndi kawopsedwe wake kwambiri. Cyanide amapha kwambiri zamoyo zam'madzi, mbalame, ndi zoyamwitsa. Ngati cyanide itatayika pamalo a migodi, imatha kuwononga magwero amadzi apafupi, zomwe zimapangitsa kufa kwa nsomba ndi zamoyo zina zam'madzi. Ngakhale cyanide yochepa m'madzi imatha kusokoneza chilengedwe chonse. Mwachitsanzo, cyanide ikhoza kulepheretsa ntchito ya cytochrome c oxidase m'maselo, kulepheretsa kugwiritsa ntchito mpweya wabwino mu kupuma kwa aerobic.

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.
