Ukubaluleka kunye noLawulo loKhuseleko lweSodium Cyanide kuShishino lwezeMigodi

intshayelelo

Kwi Icandelo lezemigodi, Isodium cyanide idlala indima ebalulekileyo ekukhutshweni kweentsimbi ezixabisekileyo, ngakumbi igolide nesilivere. Nangona kunjalo, indalo yayo eyityhefu kakhulu ifuna ukuba ngqongqo Ulawulo loKhuseleko ukuqinisekisa intlalontle yabasebenzi, ukukhusela okusingqongileyo, kunye nokugcina ukusebenza okuzinzileyo kwemisebenzi yemigodi.

Ukubaluleka kweSodium Cyanide kwiMigodi

Ukutsalwa kwegolide kunye neSilivere

Ukusetyenziswa okubaluleke kakhulu sodium cyanide emigodini ikwinkqubo yecyanidation yokukhutshwa kwegolide nesilivere. Igolide nesilivere zidla ngokuvela kwi-low - grade ores, kunye i-cyanide yenza umxube onyibilikayo ngezi ntsimbi zixabisekileyo. Phambi kweoksijini kunye namanzi, Isodium cyanide idibana negolide okanye isilivere kwintsimbi ekrwada, yenze isinyithi - cyanide complex ion, njenge [Au(CN)₂]⁻ okanye [Ag(CN)₂]⁻. Olu bunzima lunokwahlulwa ngokulula kwi-matrix ye-ore, ngokuqhelekileyo ngenkqubo ye-adsorption kwi-activated carbon okanye ngokusebenzisa ezinye iindlela zekhemikhali 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.

Ulawulo loKhuseleko lweSodium Cyanide kwiMigodi

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 esiyimfuneko kwishishini lemigodi, esenza ukuba kutsalwe iintsimbi ezixabisekileyo ngendlela esebenzayo nengabizi kakhulu. Nangona kunjalo, ubuthi bayo bufuna ukuphunyezwa kwamanyathelo okulawula ukhuseleko olungqongqo. Ngokuqinisekisa Ukuthotyelwa koMthetho, ukugcinwa okufanelekileyo, ukuthutha, ukuqeqeshwa kwabasebenzi, kunye nokulawulwa kwenkunkuma, ishishini lezemigodi lingaqhubeka nokusebenzisa i-sodium cyanide ngelixa linciphisa ingozi ehambelanayo kwimpilo yabantu kunye nokusingqongileyo.
