Kumvetsetsa Zomwe Msika wa Sodium Cyanide M'chigawo cha Africa

Kuwonjezeka Kwa Kufuna Kuchokera ku Zochita Zamigodi Ya Golide

Makampani opanga migodi ya golide nthawi zonse akhala akuchititsa kuti sodium cyanide ifunike ku Africa. Africa pang'onopang'ono ikukhala malo ofunikira kwambiri pantchito zamigodi padziko lonse lapansi. Mu njira ya mankhwala yochotsera golide , Sodium Cyanide imagwira ntchito yofunika kwambiri kudzera mu njira yochotsera golide . Mu njira iyi, miyala imaphwanyidwa kukhala ufa wabwino kenako n’kuchiritsidwa ndi yankho la Sodium cyanide kuti ipange mankhwala agolide osungunuka m’madzi. Poyerekeza ndi njira zina zochotsera golide, njirayi imakondedwa kwambiri chifukwa cha kulimba kwake pazachuma, kusavuta kugwira ntchito, komanso kukhazikika kwa chilengedwe. Mu 2021, makampani opanga golide ku Africa adawonetsa mphamvu zambiri, ndikupanga golide wa matani 680.3. Pakati pawo, Ghana idakhala yachiwiri - wogulitsa golide wamkulu ku Africa mu 2022, ndikupanga matani pafupifupi 90.

Kumadzulo kwa Africa kwakhala malo abwino kwambiri ofufuzira golide. Chifukwa chakuti migodi yambiri sinapangidwebe, yakopa ndalama zambiri zapadziko lonse lapansi. Kukula kosalekeza kwa zomangamanga za migodi m'derali kukuonekera bwino kuchokera kuzinthu zake zodabwitsa za golide, kuphatikizapo mapulojekiti 367 omwe akufufuzidwa, katundu 24 omwe akuwunikidwa pazachuma, ndi katundu 61 omwe akupangidwa kapena kumangidwa. Ntchito zazikulu zamigodi monga mgodi wagolide wa South Deep, mgodi wagolide wa Kromdraai, ndi mgodi wagolide wa Mponeng ku South Africa nthawi zonse zimapangitsa kuti pakhale kufunikira kwa sodium cyanide mu ntchito zawo zofukula. Kupezeka kwa makampani ambiri amigodi padziko lonse lapansi komanso chitukuko chosalekeza cha mapulojekiti atsopano amigodi kumalimbitsa chiyembekezo cha kufunikira kwa zinthu zopangira migodi m'makampani opanga migodi yagolide m'derali.

Kuchulukitsa Kufunika Kwa Kugwiritsa Ntchito Chemical ndi Polymer Synthesis

Indasitale ya khemikhali ndi gwere lofunika kwambiri la kugwiritsiridwa ntchito kwa sodium cyanide, makamaka ku South Africa, kumene makampani a mankhwala amatengera pafupifupi 25% ya malonda opangira zinthu mdziko muno. Sodium cyanide (NaCN) ili ndi njira zambiri zogwiritsira ntchito mankhwala osiyanasiyana, kuphatikizapo kupanga ma polima, cyanuric chloride, ndi cyanogen chloride. Mafakitale amphamvu a maindasitale a ku South Africa ndi udindo wake ngati umodzi mwa mizinda ikuluikulu ya indasitale ya mankhwala mu Afirika zikupereka thandizo lolimba pa chitukuko cha makampani opanga mankhwala. Kuchuluka kwazinthu zopangira komanso kuchulukitsa ndalama zakunja kumabweretsa mwayi wokulirapo kwamakampani opanga mankhwala mdziko muno.

Kukula kosalekeza kwamakampani opanga pulasitiki ku Africa kumalimbikitsanso kufunikira kwa sodium cyanide mu kaphatikizidwe ka polima ndi magawo ena ogwiritsira ntchito mankhwala. Makampani opanga mankhwala, monga gawo lofunikira la kumtunda kwa mafakitale amigodi ndi aulimi, amapangitsa kuti pakhale kufunikira kosiyanasiyana kwa mankhwala opangira golide. Opanga mankhwala akuluakulu monga Sasol, omwe amagwiritsa ntchito malo opangira sodium cyanide motsatira malamulo a International Cyanide Management Code, amakumana mosalekeza ndi kuchuluka komwe kukufunika kuchokera kuzinthu zosiyanasiyana zama mankhwala. Kuphatikizika kwa makampani opanga mankhwala ndi zigawo zina zamafakitale, kuphatikiza chithandizo chachitsulo, kupanga utoto, ndi kupanga agrochemical, kumayendetsanso kugwiritsiridwa ntchito kwa ma reagents amigodi mukugwiritsa ntchito kaphatikizidwe ka mankhwala.

Ndikoyenera kutchula kuti m'munda wapadziko lonse wa sodium cyanide, Shaanxi United Chemical chikuwoneka ngati m'modzi mwa otsogola opanga ndi ogulitsa sodium cyanide. Kampaniyo ili ndi mafakitale aukadaulo, umisiri wotsogola wopanga, ndi machitidwe okhwima owongolera, ndipo imatha kupatsa makasitomala zinthu zapamwamba komanso zotsika mtengo za sodium cyanide. Kaya ndi migodi ya golide kapena minda yamankhwala ndi polima kaphatikizidwe, Shaanxi United Chemical imatha kukwaniritsa zosowa zosiyanasiyana za makasitomala osiyanasiyana ndi zinthu zake zapamwamba kwambiri ndikuthandizira kukulitsa mafakitale osiyanasiyana.
