Abo bahlala kwisixeko saseRussia iNorilsk, kanye ngaphakathi kwiArctic Circle, bebethumela iifoto kwimithombo yeendaba zentlalo ukuba yintoni umlambo obomvu. Ukuba besingayazi imvelaphi yayo kunye izizathu zalo mlambo utshintshe umbala wayo wabomvu, ngokuqinisekileyo sinokuthi siza kuba sekupheleni kwexesha, njengoko bekunokwenzeka kwiinkulungwane ezidlulileyo.
Abasemagunyeni baseRussia baqalisile ukuphanda Kwaye bajonge emgodini ekhupha isinyithi njengoyena nobangela. INorilsk sisixeko seshishini esinongcoliseko oluninzi kwaye likhaya laseNorilsk Nickel, umgodi omkhulu omkhulu okhutshwe nge-nickel njengezinto zawo ezigqwesileyo ngokugqwesa.
Umphathiswa wezomkhosi wase-Russia kunye nemikhosi yasekuhlaleni ithe umbala obomvu onegazi kusenokwenzeka ukuba ibangelwe kukuqhekeka kwenye yemibhobho yeNorilsk Nickel. Zizo iingcali ezithi amagunya aseRussia mhlawumbi ajonge kwicala elilungileyo.
Umbala oqaqambileyo obomvu ikakhulu ngenxa ye- intsimbi enomhlwa Inkunkuma eseleyo. Akucaci ukuba loluphi uhlobo lwenkqubo ye-nickel esele isetyenzisiwe kwisityalo sesinyithi, kodwa kuyaziwa ukuba ezinye iintlobo zobushushu obuphezulu okanye iinkqubo zoxinzelelo lwe-oxidation ziguqula nayiphi na imaminerali ye-sulfide kwi-iron oxide. Ukuba ixutywe namanzi, intsalela iba bomvu ngokuqaqambileyo.
Kuyenzeka ukuba ifayile ye I-nickel ore eqingqiweyo ikwanazo nezixa ezikhulu zentsimbi, eziyilahla njengenkunkuma. Kule meko, intsalela etyebileyo yentsimbi ngeye yaphelela emlanjeni, yajika yajika yaba bomvu, utshilo uRonald Cohen, unjingalwazi wezobunjineli kwezendalo nakwiziko lobunjineli kwiColorado School of Mines.
Ukuba ibiyi ukuhluza imichiza, idolophu isengozini. Amanzi anoxinzelelo oluphezulu lwenkunkuma yezimbiwa anokuba yityhefu, kuxhomekeke kuhlobo luni lweekhemikhali ezivuziswe emanzini kunye nakuyiphi na ingxinano.
Ayiloxesha lokuqala kwenzeka into efanayo kwisixeko saseNorilsk, kuba kwakulo nyaka kaJuni kwenzeka njengoko abantu basekuhlaleni besitsho.
