IMarike yeSodium Cyanide: Ulawulo kwiMigodi kunye neNgcebiso yabaBoneleli

I-Sodium Cyanide eqinile iKhokela kwiintlobo zeeMveliso

Kwicandelo lohlobo lwemveliso ye Isodium cyanide imarike, Isodium Cyanide eqinile kulindeleke ukuba ibambe isabelo semarike esibalulekileyo esingama-73.6% ngo-2024. ikakhulu ngenxa yesicelo sayo esibanzi Icandelo lezemigodi. I-sodium cyanide eqinile ibe yinto ekhethekileyo yokuzikhethela kwinkqubo yokukhutshwa kwemigodi, ngokukodwa kuba kulula ukuyiphatha kunye nokuthutha. Ikristale yayo ezinzileyo okanye isakhiwo segranular yenza ukupakishwa kunye nokuthutha kube yimpepho. Umzekelo, inokupakishwa kwizikhongozeli ezomeleleyo nezingangeni moya, kwaye ngexesha lokuthuthwa, akukho mngcipheko wokuvuza, nto leyo eyinkxalabo enkulu kwimichiza engamanzi.

I-sodium cyanide eqinile isetyenziswa rhoqo xa kutsalwa igolide Inkqubo yeCyanidation. Ngenxa yokunyibilika kwayo okuphezulu emanzini, xa ixutywe ne-ore pulp, inyibilika ngokulula kwaye ikhuphe iiyoni zecyanide. Le ndawo yenza ukuba igolide ifumaneke ngokufanelekileyo nakwizinto ezixubeneyo zomgangatho ophantsi. Ngokomzekelo, kwimigodi yegolide emininzi ehlabathini lonke, ukusetyenziswa kwesodium cyanide kunyuse izinga lokufunyanwa kwegolide ngomda omangalisayo. Ukongezelela, isakhiwo sayo esiqinileyo esizinzileyo sivumela ukugcinwa okukhuselekileyo kwiindawo zemigodi. Akukho mfuneko yakuzikhathaza ngokuchitheka okanye ukuvuza njengakwimeko yezikhongozeli ezingamanzi. Oku kunciphisa kakhulu iinkxalabo zokhuseleko ezinxulumene nokuthutha kunye nokugcinwa.

Kwimisebenzi yezimayini, ukuhlanganiswa okungenamthungo kwizinto ezikhoyo Ukutsalwa kwegolide inkqubo ibalulekile. I-sodium cyanide eqinile ihlangabezana nale mfuneko ngokugqibeleleyo. Ingangeniswa ngokulula kwitanki ye-cyanidation kwaye ichithwe ngokukhawuleza. Iimpawu zayo ezizinzileyo zokuchithwa nazo zivumela ulawulo oluchanekileyo lwedosi ye-cyanide, ukwandisa ukusebenza kakuhle kwenkqubo yokukhutshwa. Ngaphezu koko, ukuphathwa ngokukhuselekileyo kwefomu eqinile kwenza kube lula ukulawulwa kwe-sodium cyanide kwimigodi, inceda ukuhlangabezana nemigangatho yokusingqongileyo kunye nokhuseleko. Lilonke, ngenxa yokhuseleko, lula, kunye nokusebenza kakuhle kwi-leaching yegolide, i-sodium cyanide eqinileyo yamkelwa ngokubanzi kumzi mveliso wezimayini, okhokelele kwindawo yayo ebalaseleyo kwicandelo lemveliso yesodium cyanide yehlabathi.

Ishishini lezemigodi: Oyena Mthengi mkhulu weSodium Cyanide

Ngo-2024. ishishini lezimayini kuqikelelwa ukuba liza kuphendula kwi-37.8% yesiphelo sesodium cyanide yehlabathi - icandelo lemarike yomsebenzisi. Isodium cyanide ibe yinxalenye eyimfuneko kwimisebenzi yokwembiwa kwegolide. Ngaphezulu kwe-90% yegolide esembiwa kwihlabathi jikelele itsalwa ngenkqubo yecyanidation exhomekeke kwisodium cyanide. Ngaphandle kwegolide, i-sodium cyanide ikwadlala indima ebalulekileyo ekubuyiselweni kwesilivere kunye nezinye izinyithi kwi-ores. Kuqikelelwa ukuba ixabiso legolide eliveliswa ngonyaka kusetyenziswa i-sodium cyanide njenge-agent leaching ranges ukusuka kwi-20 - 25 billion. Nokuba ukonyuka kwe-1 - 2% kwireyithi yokubuyisela kwakhona kusetyenziswa indlela ye-cyanidation kunokwandisa kakhulu inzuzo yeeprojekthi zemigodi. Ngomlinganiselo wokufunyanwa kwakhona ongaphezu kwama-80% kwi-cyanide-based extraction, iseyeyona nkqubo isetyenziswa kakhulu.

Njengoko imfuno yehlabathi yegolide iqhubeka ikhula, kwaye iinzame zokuhlola zigxininisa ngakumbi kwiidiphozithi zomgangatho ophantsi, ukusetyenziswa kwe-sodium cyanide kwishishini lemigodi nako kuyanda. I-sodium cyanide yenza ukuba kusetyenziswe uqoqosho noluzinzileyo lweedipozithi ebezingenaqoqosho ngaphambili. Ngokwandisa izinga lokubuyisela kwakhona, ivula amandla ophuhliso lwenani elikhulu lemithombo yegolide yegolide ephantsi. Oku, kwakhona, kwandisa ubomi beeprojekthi zemigodi kwaye kudala imfuno yexesha elide kunye nezinzileyo ye-sodium cyanide kwishishini lemigodi. Ngokweqhinga, ishishini lemigodi lixhomekeke kwisodium cyanide ukugcina igolide yehlabathi kunye namanye amanqanaba emveliso yesinyithi, nangona amanqanaba e-ore ehla. Esi sesona sizathu siphambili sesabelo sayo esiphezulu kwimarike yomsebenzisi wokugqibela. Ngenxa yokuba i-sodium cyanide iphucula ukwenzeka kwemigodi, ukusetyenziswa kwayo kule ntsimi kulindeleke ukuba kukhule ngokuhambelana nokuveliswa kwemigodi yexesha elizayo.
