Shaanxi United Chemical: Kupereka Mayankho a Green Sodium Cyanide ku Kazakhstan

M'munda wa mankhwala mankhwala kotunga, Shaanxi United Chemical wakhala ali patsogolo pa makampani ndi chithunzi cha akatswiri ndi udindo. Tsopano, ndife olemekezeka kwambiri kuti titha kupereka zabwino kwambiri Sodium Cyanide zinthu za Kazakhstan.

Sodium cyanide, monga mankhwala ofunika kwambiri opangira mankhwala, amagwiritsidwa ntchito kwambiri m'mafakitale ambiri, makamaka m'migodi ya golide ndi kupindula. Komabe, chifukwa cha katundu wake wapadera, imayendetsedwa mosamalitsa ndi boma la China. Tikudziwanso mozama za kuvulaza komwe kungachitike sodium cyanide ku chilengedwe. Ngati cyanide - yomwe ili ndi madzi oipa omwe amapangidwa mu migodi ya golidi ndi njira yopezera phindu silikonzedwa bwino, idzakhala chiwopsezo chachikulu cha chilengedwe. Cyanide m'madzi owonongeka a zomera za golide cyanidation amatsimikiziridwa ndi mapangidwe a miyala ndi momwe amagwirira ntchito. Kuphatikiza pa cyanide, ilinso ndi zinthu monga thiocyanate. Ambiri mwa ma thiocyanatewa amachokera ku njira ya aeration popanga kapena momwe amachitira pakati pa maatomu a cyanide ndi osakhazikika a sulfure panthawi ya leaching. Kuphatikiza apo, cyanide - yomwe ili ndi madzi otayira imakhala ndi zinthu zambiri zapoizoni zachitsulo za cyanide. cyanides. Chifukwa chake, Shaanxi United Chemical siwogulitsa mankhwala komanso ndi katswiri wa Chitetezo cha chitetezo.

Ubwino Woteteza Chilengedwe

Pankhani ya chitetezo cha chilengedwe, tili ndi ubwino waukulu. Kampaniyo imayika ndalama zambiri pakufufuza zaukadaulo ndi chitukuko, ndipo imapereka chithandizo chokwanira chaukadaulo pamavuto omwe angabuke pakupanga, kuyendetsa, kusunga ndi kugwiritsa ntchito. Sodium cyanide. Gulu lathu la akatswiri litha kuthandiza mabizinesi am'deralo ku Kazakhstan kukhazikitsa dongosolo lathunthu loyang'anira zachilengedwe ndikuchepetsa m'badwo woyipa kuchokera kugwero. Mwachitsanzo, popanga, timagwiritsa ntchito matekinoloje apamwamba obiriwira kuti apititse patsogolo kagwiritsidwe ntchito kazinthu zopangira komanso kuchepetsa kutulutsa zinyalala.

Njira Zochizira Cyanide - zomwe zili ndi Madzi Otayira

Pochiza cyanide - yomwe ili ndi madzi onyansa m'migodi ya golide ndi kupindula, timadziwa njira zingapo zokhwima komanso zothandiza:

• Njira ya Alkaline Chlorination: Iyi ndi njira yodziwika yowononga Cyanides m'madzi onyansa a zomera za golide za cyanidation ndipo amagwiritsidwa ntchito kwambiri pochiza madzi onyansa a cyanide electroplating zomera, zomera za golide za cyanidation, zomera za golide za cyanidation ndi magawo ena. Mfundo yake ndikugwiritsa ntchito madzi a klorini, gasi wa klorini kapena ufa wowulitsa kuti oxidize cyanide m'madzi onyansa kukhala zinthu zopanda poizoni monga carbon dioxide ndi nitrogen.

• Sulfur Dioxide - Njira Yothirira Mpweya: Imadziwikanso kuti njira ya InCo, idapangidwa ndi American InCo Metals Company koyambirira kwa 1980s. Njira imeneyi imagwiritsa ntchito sulfure dioxide ndi mpweya monga okosijeni kuti oxidize ma cyanides m'madzi oipa pansi pa chikhalidwe cha mkuwa - ion chothandizira, kupanga bicarbonate ndi ammonium ferrous sulfate. Sizingatheke kuchotsa ayoni a cyanide aulere, ma molekyulu a haidrojeni ndi ma cyanides ovuta, komanso kuthetsa zovuta za ferrocyanide zomwe zimakhala zovuta kuchotsa ndi njira ya chlorination, zomwe zimapangitsa kuti madzi otayira azigwiritsidwa ntchito kuti akwaniritse miyezo yotulutsa.

• Hydrogen Peroxide Oxidation Njira: Ndi oyenera kuchiza low-concentration cyanide - okhala ndi madzi oipa. Pansi pa zochita za mkuwa - ion chothandizira pa alkaline pH mtengo wa 10 - 11. hydrogen peroxide oxidizes cyanides kupanga mankhwala zinthu monga oxides ndi ammonium ferrous sulfate. Pakati pawo, ayoni olemera kwambiri amapanga hydroxide precipitates, ndi ayoni a ferrocyanide ndi ayoni ena olemera kwambiri amapanga mchere wovuta wa ferrocyanide.

• Njira ya Ozone Oxidation: Ndioyenera kuchitira cyanide wocheperako - wokhala ndi madzi otayira. Pa pH ya alkaline ya 11 - 12. ozoni imatulutsa ma cyanides kuti apange bicarbonate ndi nitrogen. Ngakhale njira iyi siingathe kuchotsa ma ferrocyanide complexes, ili ndi ubwino wa kuphweka komanso kosavuta. Palibe chifukwa chogula ndi kunyamula mankhwala, ndipo jenereta yokha ya ozone ndiyofunikira kuti athetse cyanide - yomwe ili ndi madzi oipa. Komabe, ilinso ndi zovuta zogwiritsa ntchito mphamvu zambiri komanso ndalama zambiri zamankhwala. Pofuna kuthetsa vuto la ferrocyanide complexes, Tinker Air Force Base ku United States inapanga njira yophatikizana ya ultraviolet photolysis ndi ozoni ndikuyesa bwino. Pambuyo pake, njira yofananira ya O3/photolysis idapangidwanso.

Chitsimikizo cha Mayendedwe ndi Kusunga

Mu ulalo wa mayendedwe, tili ndi zida zonyamulira mankhwala owopsa komanso njira zowongolera zoyendera kuti tiwonetsetse kuti sodium cyanide ifika bwino komwe ikupita ndikuchepetsa kuwononga chilengedwe panjira. Pankhani yosungira, timapereka njira zosungiramo zasayansi ndi zida zopewera ngozi monga kutayikira kuti zisawononge nthaka ndi magwero amadzi. Pakakhala zochitika zosayembekezereka, tilinso ndi akatswiri odziwa chithandizo chadzidzidzi komanso magulu omwe amatha kuyankha mwachangu ndikuchepetsa kuwonongeka kwa chilengedwe.

Shaanxi United Chemical adzipereka kugwira ntchito limodzi ndi anzawo ku Kazakhstan kuti akwaniritse chitukuko chobiriwira komanso chokhazikika pomwe akupereka zinthu zapamwamba za sodium cyanide. Tikukhulupirira kuti kudzera muzoyesayesa zathu, titha kuthandizira pakukula kwa mafakitale ku Kazakhstan ndikuwonjezeranso chitsimikiziro choteteza chilengedwe.
