Green Gold Mining e Kyrgyzstan kunye Sodium Cyanide ukusuka United Chemical

Kumhlaba otyebileyo wemithombo yezimbiwa eKyrgyzstan, Ukumbiwa kweGolide ukwisikhundla esibalulekileyo. Ngophuhliso olukhulayo loshishino lwezimayini, imfuno yobuchwepheshe bemigodi esebenzayo kunye neekhemikhali eziphambili ziyanda imihla ngemihla. Njengomboneleli wehlabathi ohamba phambili we Isodium cyanide, United Chemical, kunye neziqinisekiso zayo ezisemthethweni nezithobelayo zokungenisa nokuthumela ngaphandle kunye nokuqokelela okunzulu kobugcisa, ayinikezeli kuphela umgangatho ophezulu sodium cyanide iimveliso kwishishini lemigodi yegolide eKyrgyzstan, kodwa kwakhona uzibophelele ekubeni liqabane elomeleleyo kukhuseleko lokusingqongileyo, ukuphendula ngenkuthalo kunye nokuququzelela ukuphunyezwa kwemigaqo-nkqubo yelizwe yokhuselo lokusingqongileyo kunye nemimiselo ngokutsha eluhlaza.

I. Umgangatho ophezulu we-Sodium Cyanide, Ukuvula ucango lweMigodi esebenzayo

Isodium cyanide idlala indima ebaluleke kakhulu emigodini yegolide. Inokwenza iikhompleksi ezinyibilikayo ezinegolide kwintsimbi ekrwada yegolide, ngaloo ndlela ivumela ukutsalwa ngokufanelekileyo kwegolide. I Isodium cyanide iimveliso eziveliswa ngu United Chemical zinococeko oluphezulu kakhulu kunye nomxholo wobumdaka obuphantsi kakhulu. Oku kuqinisekisa ukuba kwinkqubo yokwembiwa kwegolide, esona siphumo silungileyo sokuvuza sinokufezekiswa ngomlinganiselo omncinci wokusetyenziswa, ukuphucula kakhulu ukusebenza kakuhle kunye neenzuzo zoqoqosho zokumbiwa kwegolide. Nokuba kukumbiwa kwemigodi emikhulu yegolide okanye ukusebenza kakuhle kwemigodi emincinci, iimveliso zethu zesodium cyanide zinokulungiswa ngokuchanekileyo ukuze zihlangabezane neemfuno zeemeko ezahlukeneyo zemigodi.

II. I-Green Technology Escort, ukuSombulula iiNkxaso zokusiNgqongileyo

Siyazi ngokunzulu iingozi ezinokubakho ukusetyenziswa kwe-sodium cyanide kunokuzisa kwindalo. Ukuya koku kuphela, United Chemical utyale isixa esikhulu semithombo yophando kunye nokuphuhlisa nokuphucula uthotho lwezinto eziphambili Ubuchwephesha boKhuseleko lokusiNgqongileyo, ejonge ukubonelela ngoluhlu olupheleleyo lwezisombululo zokusingqongileyo kumashishini emigodi yegolide eKyrgyzstan.

Kwikhonkco lokusebenzisa i-sodium cyanide, sikhuthaza inkqubo ye-cyanidation epheleleyo ye-slime kunye ne-low-cyanide leaching technology. Inkqubo ye-cyanidation ye-slime epheleleyo ikhulisa inkqubo yokulungiswa kwe-ore kwangaphambili, ivumela i-sodium cyanide ukuba iqhagamshelane neentsimbi zegolide ngokulungeleleneyo ngakumbi, inciphisa ngokufanelekileyo inani le-sodium cyanide esetyenziswayo ngelixa isonyusa izinga legolide. Itekhnoloji ye-low-cyanide leaching technology iqonda ukutsalwa okusebenzayo kwegolide phantsi kweemeko zokuxinana kwe-cyanide ephantsi ngokongeza izongezo ezikhethekileyo, ukunciphisa kakhulu ukukhutshwa kweecyanides.

Kunyango lwamanzi amdaka ane-cyanide, sibonelela ngetekhnoloji yonyango ehlanganisiweyo ekhulileyo yemvula yeekhemikhali kunye nokuthotywa kwe-biodegradation. Okokuqala, i-chemical precipitation method isetyenziselwa ukuguqula i-cyanides kumanzi amdaka ibe yi-precipitates engekho yingozi, isusa ininzi ye-cyanides. Emva koko, ngenkqubo ye-biodegradation, ii-microorganisms ezithile zisetyenziselwa ukubola ngakumbi i-cyanides eseleyo, ukuqinisekisa ukuba amanzi amdaka ahlangabezana nemigangatho engqongqo yokukhutshelwa kokusingqongileyo yaseKyrgyzstan phambi kokuba akhutshelwe.

Ngemimiselo yokuba Ukulahlwa kweentsila, siye sazisa ii-tailings eziphambili zokukhupha ezomileyo kunye nokuqina kobuchwepheshe. Ubuchwephesha bokukhutshwa komsila obomileyo buhlukanisa kakhulu amanzi kwi-tailings, ukunciphisa umngcipheko wokuqokelelwa kwamanzi kwi-tailings echibini kwaye kwangaxeshanye kuncitshiswe amathuba okusasazwa kwe-cyanide ngamanzi. Itheknoloji yokuqinisa idibanisa i-tailings kunye nee-agent ezikhethekileyo zokuqinisa ukwenza izinto eziqinileyo, ukuthintela ngokufanelekileyo ukuvuza kwezinto ezinobungozi kwi-tailings kunye nokubeka isiseko sokubuyiselwa komhlaba okulandelayo kunye nokubuyiselwa kwezinto eziphilayo.

III. UkuPhendula ngenkuthalo kwiMigaqo-nkqubo kunye nokuFaka iGalelo kuLwakhiwo lweMigodi yoHlaza

United Chemical ibisoloko idibanisa ingcamango yophuhliso lohlaza kuzo zonke iinkalo zoshishino lwalo kwaye isabela ngenkuthalo kwikhwelo likarhulumente waseKyrgyzstan lokwakhiwa kwemigodi eluhlaza. Siye safunda ngokunzulu imigaqo-nkqubo kunye nemimiselo yendawo kwaye safikelela kwintsebenziswano enzulu kunye noorhulumente basekhaya kunye namashishini ukukhuthaza ngokubambisana ukwakhiwa kwemigodi eluhlaza.

Iqela lethu lobuchwephesha lenze uphando olubanzi noluneenkcukacha kunye nohlalutyo lweemeko zejoloji, indalo esingqongileyo kunye nembali yezemigodi kuyo yonke imigodi, kwaye ilungiselelwe. Ukwakhiwa kweMigodi eluhlaza izicwangciso ngokufanelekileyo. Ukuqala kumthombo, siphucula inkqubo yemigodi, samkele itekhnoloji ephucukileyo yongcoliseko oluphantsi lwezemigodi, kunye nokunciphisa umonakalo kokusingqongileyo. Kwangaxeshanye, sikhuthaza ngamandla usetyenziso olubanzi lwemithombo yobutyebi, siphucula izinga lokubuyiselwa kobutyebi bezimbiwa, nokunciphisa ukwenziwa kweentsalela zezimbiwa.

Ayisiyiyo loo nto kuphela, sikwabonelela ngoqeqesho lokhuseleko lokusingqongileyo kunye neenkonzo zokubonisana nobugcisa kumashishini asekuhlaleni kunye namasebe afanelekileyo ukubanceda baphucule ulwazi lwabo ngokusingqongileyo kunye nenqanaba lobugcisa, ukuqinisekisa ukuba amanyathelo ahlukeneyo okwakhiwa kwemigodi eluhlaza inokuphunyezwa ngokufanelekileyo.

IV. Ukusebenzisana ngokuBambisana ukwenza iKamva leMigodi eluhlaza

Kuhambo lophuhliso lweshishini lemigodi yegolide eKyrgyzstan, United Chemical uzimisele ukusebenzisana kunye nawo onke amaqela, ukuthatha iimveliso ze-sodium cyanide eziphezulu njengelitye lembombo, iteknoloji yokukhusela indalo njengenkxaso, kunye neempendulo zomgaqo-nkqubo osebenzayo njengamandla okuqhuba, ukukhuthaza ngokubambisana uphuhliso oluzinzileyo lweshishini lemigodi yegolide. Sikholelwa ukuba ngeenzame zethu, sinokufikelela ekuphuhliseni ngokufanelekileyo kunye nokusetyenziswa kwemithombo yegolide ngelixa sikhusela amanzi aluhlaza kunye neentaba zaseKyrgyzstan, ukudala indawo yokuhlala engcono kubantu basekuhlaleni kunye nokuvula isahluko esitsha ekuphuhliseni ishishini lemigodi eluhlaza.

Ukukhetha iimveliso ze-sodium cyanide United Chemical kuthetha ukukhetha indibaniselwano egqibeleleyo yokusebenza kakuhle, ukhuseleko kunye nokukhuselwa kwendalo. Masithathe inyathelo kunye ukuze sibe negalelo kuphuhliso lwemigodi kunye nokukhuselwa kwendalo yaseKyrgyzstan.
