Ukubaluleka kunye noLawulo loKhuseleko lweSodium Cyanide kuShishino lwezeMigodi

intshayelelo

KwiShishini leMigodi , iSodium Cyanide idlala indima ebalulekileyo ekukhutshweni kweentsimbi ezixabisekileyo, ingakumbi igolide nesilivere. Nangona kunjalo, ubume bayo obunobungozi kakhulu bufuna uLawulo oluqinileyo loKhuseleko ukuqinisekisa impilo-ntle yabasebenzi, ukukhusela okusingqongileyo, kunye nokugcina ukusebenza okuzinzileyo kwemisebenzi yemigodi.

Ukubaluleka kweSodium Cyanide kwiMigodi

Ukutsalwa kwegolide kunye neSilivere

Eyona ndlela ibalulekileyo yokusebenzisa i -sodium cyanide ekumbeni kukwinkqubo yokukhupha i-cyanidation kwigolide nesilivere. Igolide nesilivere zihlala zenzeka kwii-ore ezikumgangatho ophantsi, kwaye i-cyanide yenza i-complex enyibilikayo ngezi zinyithi zixabisekileyo. Xa kukho ioksijini namanzi, i-Sodium cyanide isabela negolide okanye isilivere kwi-ore, yenze i-ion ye-metal-cyanide complex, efana ne-[Au(CN)₂]⁻ okanye i-[Ag(CN)₂]⁻. Le complex inokwahlulwa ngokulula kwi-ore matrix, ngesiqhelo ngenkqubo yokufunxa kwi-activated carbon okanye ngokusebenzisa ezinye iindlela zeekhemikhali zokucoca ngakumbi.

Iindleko - ukusebenza kakuhle

Xa kuthelekiswa nezinye iindlela zokutsalwa, inkqubo ye-cyanidation isebenzisa i-sodium cyanide inexabiso eliphantsi. Ivumela ukutsalwa kweentsimbi ezixabisekileyo kuluhlu olubanzi lweentlobo ze-ore, kubandakanywa nezo zine-mineralogy enzima. Oku kusebenza kakuhle kweendleko kwenza ukuba iinkampani zemigodi zikwazi ukusebenza ngokunenzuzo, ingakumbi xa zijongene nemisebenzi yemigodi emikhulu apho uqoqosho lobungakanani bunokuphunyezwa.

Amazinga aphezulu okuBuyisa

Xa isetyenziswe ngokufanelekileyo, inkqubo ye-cyanidation inokufikelela kumazinga aphezulu okubuyisela igolide nesilivere. Ngokulungisa iimeko ezinje nge-pH, ukuxinana kwe-cyanide, kunye nokufumaneka kweoksijini, iinkampani zemigodi zinokukhupha ipesenti enkulu yeentsimbi ezixabisekileyo ezikhoyo kwintsimbi ekrwada. Amazinga aphezulu okubuyisela awandisi nje kuphela inzuzo yokusebenza kwemigodi kodwa anegalelo ekusetyenzisweni kakuhle kobutyebi bendalo obunyiniweyo.

Ukuthotyelwa koMthetho

Iinkampani zemigodi kufuneka zibambelele ngokungqongqo kwimimiselo yasekhaya, yelizwe kunye neyamazwe ngamazwe malunga nokusetyenziswa, ukugcinwa, kunye nokuthuthwa kwe-sodium cyanide. Le migaqo idla ngokuquka imiba efana nobona buninzi buvumelekileyo be-cyanide kumanzi amdaka, ukuleyibhelishwa okufanelekileyo kunye nokupakishwa kweemveliso zecyanide, kunye neemfuno zoqeqesho lokhuseleko lwabasebenzi ababandakanyeka kwimisebenzi enxulumene necyanide. Ukuthotyelwa kwale mimiselo akusiyo isinyanzeliso esisemthethweni kuphela kodwa kwakhona linyathelo elibalulekileyo ekuqinisekiseni ukhuseleko.

Izixhobo Zokugcina

I-sodium cyanide kufuneka igcinwe kwiindawo zokugcina ezizinikeleyo, eziyilwe kakuhle. Ezi zixhobo kufuneka zakhiwe ngezinto ezikwaziyo ukumelana nokubola zisisombululo se-cyanide. Kufuneka zibekwe kwiindawo ezikude neendawo zokuhlala, imithombo yamanzi kunye nezinye iindawo ezinobuzaza. Iitanki zokugcina kunye nezikhongozeli kufuneka zixhotyiswe ngokuvuza - iinkqubo zokubona kunye nezakhiwo zokuqulatha okwesibini ukuthintela ukukhutshwa kwe-cyanide kwimeko yokusilela kwesikhongozeli sokuqala.

Ezokhuseleko

Ngexesha lokuthutha, i-sodium cyanide kufuneka ihanjiswe ngokuhambelana nemigaqo engqongqo. Izithuthi ezikhethekileyo zothutho ziyafuneka, eziyilelwe ukunciphisa umngcipheko wokuchitheka kunye neengozi. Izithuthi kufuneka zixhotyiswe ngeekiti zokuphendula ngokukhawuleza, kubandakanywa ii-agent ezingathathi hlangothi zokuchithwa kwe-cyanide. Iindlela zothutho kufuneka zicwangciswe ngononophelo ukuthintela iindawo eziphakamileyo zezithuthi kunye neendawo ezinomonakalo omkhulu wokusingqongileyo kwimeko yengozi.

Uqeqesho noKhuseleko lwaBasebenzi

Bonke abasebenzi ababandakanyekayo ekuphatheni i-sodium cyanide kufuneka bafumane uqeqesho olubanzi lokhuseleko. Olu qeqesho kufuneka lufake iipropati ze-sodium cyanide, kubandakanywa nobutyhefu bayo, indlela yokuphatha ngokukhuselekileyo kunye nokudlulisa izisombululo ze-cyanide, kunye nokusetyenziswa ngokufanelekileyo kwezixhobo zokukhusela zomntu (PPE). Abasebenzi kufuneka baqeqeshwe kwiinkqubo zokusabela ngokukhawuleza, ezifana nendlela yokusabela kwi-cyanide spill okanye imeko ye-cyanide exposure. Uqeqesho lokhuseleko kufuneka lwenziwe rhoqo ukuqinisekisa ukuba abasebenzi bazilungiselele kakuhle naziphi na iziganeko ezinokubakho.

Ulawulo lweNkunkuma

Ishishini lezimayini lenza izixa ezibalulekileyo zecyanide - equlathe inkunkuma. Ulawulo olululo lwenkunkuma lubalulekile ukuthintela ukukhutshwa kwe-cyanide kokusingqongileyo. Amanzi amdaka aqulethe i-cyanide kufuneka acocwe ukuze kuncitshiswe ukuxinana kwe-cyanide ukuya kumanqanaba amkelekileyo ngaphambi kokukhutshelwa. Iindlela zonyango zinokubandakanya i-chemical oxidation, unyango lwebhayoloji, okanye indibaniselwano yazo zombini. Inkunkuma eqinileyo, efana neentsalela zezimbiwa, kufuneka ilawulwe ngendlela yokunciphisa umngcipheko wokuvuza kwecyanide kumhlaba ojikelezileyo namanzi.

isiphelo

I-sodium cyanide sisixhobo esibalulekileyo kwishishini lezemigodi, esivumela ukukhutshelwa kweentsimbi ezixabisekileyo ngendlela efanelekileyo nengabizi kakhulu. Nangona kunjalo, ubuthi bayo bufuna ukuphunyezwa kwamanyathelo olawulo lokhuseleko angqongqo. Ngokuqinisekisa ukuThotyelwa kweMithetho , ukugcinwa ngokufanelekileyo, ukuthuthwa, uqeqesho lwabasebenzi, kunye nolawulo lwenkunkuma, ishishini lezemigodi lingaqhubeka nokusebenzisa i-sodium cyanide ngelixa linciphisa iingozi ezinxulumene nayo kwimpilo yabantu nakwindalo esingqongileyo.
