I-Sodium Cyanide iSebenzisa iziQinisekiso kwi-Gold Mining Leaching

Sodium i-cyanide iyikhemikhali esebenza kakhulu kodwa eyingozi kakhulu esetyenziswa ngokubanzi njengearhente yokushishina kwimisebenzi yokwemba igolide. Ngenxa yobutyhefu bayo obuphezulu, ukuthotyelwa ngokungqongqo kwiiprothokholi zokhuseleko kunye neenkqubo zokuphatha ezifanelekileyo zibalulekile ukuthintela iingozi, ukukhusela impilo yabantu, kunye nokukhusela okusingqongileyo. Eli nqaku lichaza izilumkiso ezibalulekileyo zokusetyenziswa kwe sodium cyanide in imigodi yegolide iinkqubo.

1. UQeqesho lwaBasebenzi kunye neSiqinisekiso

• Uqeqesho olunyanzelekileyo: Bonke abasebenzi ababandakanyekayo ekuphatheni Isodium cyanide kufuneka ifumane uqeqesho olubanzi kwiipropathi zayo, iingozi ezinokubakho, iinkqubo zokuphatha ngokukhuselekileyo, kunye nemilinganiselo yokusabela kwimeko kaxakeka. Uqeqesho kufuneka lubandakanye ulwazi lwethiyori kunye nezakhono ezisebenzayo, kubandakanywa ukusetyenziswa ngokufanelekileyo kwezixhobo zokuzikhusela (personal protective equipment (PPE).

• Iimfuneko zokuQinisekiswa: Abasebenzi kufuneka bafumane iziqinisekiso ezifanelekileyo ukubonisa ubuchule babo bokuphatha Isodium cyanide. Iikhosi zokuhlaziya rhoqo ziyimfuneko ukugcina izakhono zabo nolwazi lusexesheni, njengoko imigangatho yoshishino kunye nezenzo zokhuseleko zinokuvela ngokuhamba kwexesha.

2. Izixhobo zoKhuseleko zoMntu (PPE)

• IGear efanelekileyo: Xa usebenza kunye ne-sodium cyanide, nxiba iimpahla ezikhusela umzimba ezipheleleyo ezenziwe ngezinto ezingenakugqunywa ukukhusela ukudibana kwesikhumba. Sebenzisa iiglavu ezikwaziyo ukumelana neekhemikhali, iiglavu zokhuseleko okanye isikhuselo sobuso esigcweleyo ukukhusela amehlo kunye nenkqubo yokuphefumla, kunye nezixhobo zokukhusela ukuphefumla ezifana nezixhobo zokuphefumla ezizimeleyo (SCBAs) okanye ezibonelelweyo - iziphefumlo zomoya, ngakumbi kwiindawo ezinokuchaphazeleka komphunga wecyanide.

• Ukuhlola kunye nokuGcina: Hlola rhoqo iPPE ukubona iimpawu zomonakalo okanye ukuguga. Faka endaweni yaso nasiphi na isixhobo esonakeleyo okanye esigugileyo ngoko nangoko ukuqinisekisa ukusebenza kwaso ekuboneleleni ngokhuseleko.

3. ImiGaqo yokuGcina

• Ukugcinwa Kwawodwa: Gcina i-sodium cyanide kwindawo yogcino olunikezelweyo, olunomoya ococekileyo ohlukaniswe kwizinto ezingahambelaniyo ezifana ne-acids, i-oxidizers, kunye nezinto ezinokutsha. Indawo yokugcina etshixiweyo enokufikelela okuthintelweyo kufuneka isetyenziswe ukuthintela ukungena okungagunyaziswanga.

• Ukuqulathwa okwaneleyo: Sebenzisa izikhongozeli ezifanelekileyo zokugcina isodium cyanide. Ezi zikhongozeli kufuneka zitywinwe ngokuqinileyo kwaye zenziwe ngezinto ezikwaziyo ukumelana nokuhlwa yicyanide. Qinisekisa ukuba indawo yokugcina inezixokelelwano zesibini zokuqulatha, ezifana neetreyi zokuchitha okanye iidikhi, ukuthintela ukusasazeka kokuchitheka okanye ukuvuza.

4. Ukuphatha kunye neeNkqubo zokuTshintshela

• Imisebenzi ecothayo nelawulwayo: Xa uhambisa i-sodium cyanide ukusuka kwesinye isikhongozeli ukuya kwesinye okanye uyifakela kwinkqubo yokuvuza, yenza umsebenzi ngokucothayo nangononophelo ukunciphisa ukuveliswa kothuli okanye umphunga. Sebenzisa izixhobo ezifanelekileyo zokutshintshela, ezifana neenkqubo zelophu ezivaliweyo okanye izixhobo zokudlulisa ezincediswayo ngevacuum, ukunciphisa umngcipheko wokuba sesichengeni.

• Ukuthintela Ukuchitheka: Thatha amanyathelo okuthintela ukuphepha ukuchithwa ngexesha lokuphatha kunye nokudluliselwa. Ukuba ukuchitheka kuyenzeka, ngoko nangoko qalisa iprotocol yempendulo yokuchitheka. Oku kunokubandakanya ukuqulatha indawo yokuchitha, ukusebenzisa izinto ezifunxayo ukucoca ukuchitheka, kunye nokulahla izinto ezingcolileyo ngokuhambelana nemimiselo yendawo.

5. Ukukhuselwa kokusiNgqongileyo

• Ulawulo lweNkunkuma: Phuhlisa isicwangciso esibanzi solawulo lwenkunkuma kwisodium cyanide - enenkunkuma. Oku kuquka unyango olululo kunye nokulahlwa kwenkunkuma, iintsalela zezimbiwa, kunye neminye imijelo yenkunkuma. Iindlela zonyango zinokubandakanya i-chemical oxidation, ukuthotywa kwezinto eziphilayo, okanye ezinye iinkqubo ezifanelekileyo zokunciphisa ubuthi be-cyanide ngaphambi kokulahlwa.

• Ukubeka iliso nokwenza iNgxelo: Hlala ubeka iliso kwimo engqongileyo engqonge isiza somgodi ukubona iimpawu zongcoliseko lwecyanide, ezinje ngomhlaba, amanzi, nomoya. Nika ingxelo rhoqo ngedatha yokubeka iliso kokusingqongileyo kwabasemagunyeni abafanelekileyo njengoko kufunwa ngumthetho.

6. Impendulo kaxakeka

• IziCwangciso eziNgxamisekileyo: Misela izicwangciso zokusabela ezingxamisekileyo ezibandakanya iimeko ezinokubakho njengokuchitheka, ukuvuza, imililo, kunye nokuba sesichengeni ngengozi. Ezi zicwangciso kufuneka zibandakanye iinkqubo zokwazisa abaphenduli bexakeka, ukukhupha abasebenzi, ukubonelela ngoncedo lokuqala, kunye nokuqulatha kunye nokucoca indawo echaphazelekayo.

• Uqeqesho kunye noQeqesho: Qhuba uqeqesho oluthe gqolo lokusabela kwimeko yonxunguphalo kunye noqheliselo kubo bonke abasebenzi ukuqinisekisa ukuba baqhelene neenkqubo zongxamiseko kwaye banokusabela ngokufanelekileyo xa kukho isiganeko. Hlaziya izicwangciso zokusabela ngokungxamisekileyo ngokusekelwe kwiziphumo zoqheliso kunye naluphi na utshintsho ekusebenzeni kwemigodi okanye iimfuno zolawulo.

Ukuqukumbela, ukusetyenziswa kwe-sodium cyanide kwi-leaching yegolide ye-mining kufuna inqanaba eliphezulu lokulumkisa kunye nokuthotyelwa okungqongqo kunye nokhuseleko kunye nemimiselo yokusingqongileyo. Ngokulandela la manyathelo okhuseleko, iinkampani zemigodi zinokunciphisa imingcipheko enxulumene nokusetyenziswa kwe-sodium cyanide, zikhusele intlalontle yabasebenzi bazo kunye nokusingqongileyo, kwaye ziqinisekise ukusebenza ngokuzinzileyo kwemisebenzi yazo yemigodi yegolide.
