Chifukwa Chake China Yakhala Wotsogola Padziko Lonse Wopanga Sodium Cyanide

Kuchokera ku 2008 mpaka 2015. China idasintha kwambiri Sodium Cyanide kupanga. Inasintha kuchoka pakukhala wogulitsa kunja kwa mankhwala oopsa kwambiri ameneŵa n’kukhala kampani yaikulu kwambiri padziko lonse yopanga, yosungira zinthu, ndi yotumiza kunja. Kusintha kwakukuluku kumabweretsa funso: chifukwa chiyani China yakhala dziko lotsogola sodium cyanide kupanga?

Global Sodium Cyanide Production Landscape

Japan anali m'modzi mwa omwe adalowa nawo koyamba Sodium cyanide kupanga domain. Ngakhale kulamulira kwa United States (ndi makampani ngati DuPont owerengera 43% ya mphamvu zonse zopanga padziko lonse lapansi) ndi Western Europe mu sodium yapadziko lonse lapansi. cyanide kupanga, makampani aku Japan monga Kuraray ndi Nippon Soda, mwa ena, athandiza Japan kukhalabe ndi mpikisano. Mu 1999, pafupifupi 50% ya sodium cyanide yotulutsa ku Japan idalowetsedwa mukupanga methionine, yomwe imagwiritsidwa ntchito kwambiri popanga chakudya cha ziweto.

Komabe, padziko lonse lapansi, njira yoyamba yogwiritsira ntchito sodium cyanide ndiyo kuchotsa golide. Popeza ukadaulo wogwiritsa ntchito sodium cyanide mumigodi ya golide udayamba m'ma 1980, wavomerezedwa kwambiri m'mafakitale agolide m'maiko osiyanasiyana. Mwachitsanzo, ku South Africa, 99.5% ya kuchotsa golide amadalira njira imeneyi; ku United States, chiwerengerochi chili pa 88.1%, ndipo ku Australia, ndi 84.9%. Pakadali pano, 75% ya sodium cyanide padziko lapansi imadyedwa ndi migodi. Makampani opanga migodi ku North America, South America, Russia, Central Asia, Australia, South Africa, ndi China ndi omwe amagwiritsa ntchito mankhwalawa.

Kukwera kwamitengo ya golide kwakhudza mwachindunji mtengo wa sodium cyanide womwe umagwiritsidwa ntchito pochotsa golide. Kumayambiriro kwa zaka za m'ma 2000, mtengo wapadziko lonse wa sodium cyanide unali pafupifupi \ (1.600 pa tani, yomwe idakwera kufika \) 2.800 pa tani. Kukwera kwamitengo kumeneku kunalimbikitsa kukula kwa kupanga sodium cyanide padziko lonse lapansi. Mwachitsanzo, Russia ndi Peru, adamanga mofunitsitsa zomera zopanga sodium cyanide zomwe zimatha kupanga matani 40.000 a sodium cyanide yolimba pachaka. Koma posakhalitsa, anaphimbidwa ndi kukula kofulumira kwa China m’derali.

China's Sodium Cyanide Production Journey

China idayamba kupanga sodium cyanide m'zaka za m'ma 1960, pomwe Shanghai inali malo oyamba kupanga. Pofika m'zaka za m'ma 1980, msika wochulukirachulukira wa petrochemical udapangitsa kuti pakhale kufunikira kwa sodium cyanide. Zisanafike 2008. China idadalira kuchokera kunja, kubweretsa 10.000 - 30.000 matani a sodium cyanide pachaka.

Komabe, mphamvu zapawiri zomwe zikuchulukirachulukira kufunikira kwamayiko ndi mayiko, kuphatikiza kukwera kwamitengo, makamaka chifukwa cha kuchuluka kwa zofunikira za Gold Mining Industry, idalimbikitsa mphamvu yaku China yopanga sodium cyanide. Pofika chaka cha 2009. China idachita bwino kwambiri pokhala wogulitsa kunja kwa sodium cyanide.

Mu 2011. Kupanga kwapachaka kwa sodium cyanide ku China kunayandikira matani 400.000. Pakalipano, dziko la China lili ndi udindo waukulu kwambiri padziko lonse wopanga sodium cyanide. Kuphatikiza pa kukwaniritsa zosowa zapakhomo, imatumiza kunja matani oposa 70.000 chaka chilichonse. Pakukula kwachangu kwamakampani a sodium cyanide, zigawo ngati Anhui ndi Hebei zidawoneka ngati malo akuluakulu opanga.

Magalimoto Oyendetsa Kumbuyo Kwa Kukwera kwa China

Gold Mining Industry

China sikuti ndi otsogola opanga komanso ogula kwambiri golide. Kukula kosalekeza pakupanga ndi kugwiritsa ntchito golide kwadzetsa kufunikira kwa sodium cyanide pakupanga migodi ya golide. Kutulutsa golide ku China kwakhala nthawi yayitali pakati pa apamwamba padziko lonse lapansi. Kugwiritsa ntchito kwambiri njira yochotsa golide yochokera ku cyanide, yomwe imagwira bwino ntchito pochotsa golide ku ore, kwathandizira kwambiri kufunikira kwa sodium cyanide. Pamene migodi ya golide ikukulirakulirabe, pokhudzana ndi ntchito zatsopano zamigodi komanso kukulitsa zomwe zilipo kale, kufunikira kwa sodium cyanide monga chinthu chofunika kwambiri chochotsamo chakula molingana.

Mtengo - kuchita bwino ndi Scale Phindu

Opanga aku China adagwiritsa ntchito chuma chambiri. Ndi kupanga kwakukulu, atha kuchepetsa kwambiri ndalama zopangira. Kukwera mtengo kumeneku kwapangitsa China - kupanga sodium cyanide kukhala yopikisana pamsika wapadziko lonse lapansi. Kuphatikiza apo, kutukuka kwaukadaulo wapamwamba wopanga ku China kwapititsa patsogolo luso la kupanga komanso mtundu wazinthu. Kutha kupanga sodium cyanide yapamwamba kwambiri pamtengo wotsika wakopa makasitomala apakhomo ndi akunja, motero kumapangitsa kukula kwamakampani.

Kukula kwa Makampani a Downstream

Sodium cyanide imagwira ntchito ngati zida zofunika kwambiri m'mafakitale osiyanasiyana akumunsi, kuphatikiza kupanga mankhwala apakatikati, mankhwala, mankhwala ophera tizilombo, ndi electroplating. Kukula kwa mafakitalewa ku China kwadzetsa kufunikira kwakukulu kwa sodium cyanide. Mwachitsanzo, m'makampani opanga mankhwala, sodium cyanide imagwiritsidwa ntchito popanga mankhwala ena apakati. Pamene makampani opanga mankhwala aku China akuchulukirachulukira ndikupikisana kwambiri padziko lonse lapansi, kufunikira kwa sodium cyanide ngati zopangira zoyambira kwakulanso. Momwemonso, mumakampani opanga ma electroplating, omwe amagwiritsidwa ntchito kwambiri popanga zamagetsi ndi zinthu zokongoletsera, sodium cyanide imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti plating yapamwamba kwambiri. Kukula kwa mafakitale akumunsiwa kwapereka maziko olimba a chitukuko cha kupanga sodium cyanide ku China.

Kutsiliza

Mwachidule, kusintha kwa China kukhala mtsogoleri wotsogola padziko lonse wa sodium cyanide ndi chifukwa cha zinthu zosiyanasiyana. Kuchuluka kwa kuchuluka kwa mafakitale a migodi ya golide, njira zogwirira ntchito zotsika mtengo, komanso kutukuka kwa mafakitale akumunsi kwa migodi za golide zathandizira kukula kodabwitsaku. Komabe, ndi kukula uku kumabwera ndi udindo woonetsetsa kuti chitetezo ndi njira zotetezera zachilengedwe. Popeza sodium cyanide ili ndi poizoni kwambiri, kugwiritsiridwa ntchito moyenera, kusungidwa, ndi mayendedwe ndikofunikira kwambiri. Pamene China ikupitirizabe kukhala patsogolo pa kupanga sodium cyanide, iyeneranso kutsogolera kugwiritsa ntchito njira zabwino zotetezera ndi kuteteza chilengedwe kuti kuchepetsa zoopsa zomwe zingagwirizane ndi mankhwala oopsawa.
