I-Sodium Cyanide iSebenzisa iziQinisekiso kwi-Gold Mining Leaching

I-sodium cyanide yikhemikhali esebenza kakhulu kodwa enobungozi kakhulu esetyenziswa kakhulu njenge-arhente yokukhupha igolide kwimisebenzi yokwemba igolide. Ngenxa yobutyhefu bayo obuphezulu, ukunamathela ngokungqongqo kwimigaqo yokhuseleko kunye neenkqubo ezifanelekileyo zokuphatha kubalulekile ukuthintela iingozi, ukukhusela impilo yabantu, kunye nokukhusela okusingqongileyo. Eli nqaku lichaza amanyathelo abalulekileyo okusebenzisa i -sodium cyanide kwiinkqubo zokukhupha igolide.

1. UQeqesho lwaBasebenzi kunye neSiqinisekiso

• Uqeqesho Oluyimfuneko : Bonke abasebenzi ababandakanyekayo ekuphatheni iSodium Cyanide kufuneka bafumane uqeqesho olupheleleyo malunga neempawu zayo, iingozi ezinokubakho, iinkqubo zokuphatha ezikhuselekileyo, kunye namanyathelo okuphendula ngexesha likaxakeka. Uqeqesho kufuneka lugubungele ulwazi lwethiyori kunye nezakhono ezisebenzayo, kubandakanya ukusetyenziswa ngokufanelekileyo kwezixhobo zokuzikhusela zomntu (PPE).

• Iimfuneko zeSatifikethi : Abasebenzi kufuneka bafumane iziqinisekiso ezifanelekileyo ukubonisa ubuchule babo ekuphatheni iSodium cyanide . Iikhosi zokuhlaziya rhoqo ziyafuneka ukuze izakhono nolwazi lwabo luhlale lusexesheni, njengoko imigangatho yoshishino kunye neendlela zokhuseleko zinokutshintsha ngokuhamba kwexesha.

2. Izixhobo zoKhuseleko zoMntu (PPE)

• Izixhobo ezifanelekileyo : Xa usebenza nge-sodium cyanide, nxiba impahla yokukhusela umzimba wonke eyenziwe ngezinto ezingangeni manzi ukuthintela ukudibana nolusu. Sebenzisa iiglavu ezimelana neekhemikhali, iiglasi zokhuseleko okanye isikhuselo sobuso esipheleleyo ukukhusela amehlo kunye nenkqubo yokuphefumla, kunye nezixhobo zokukhusela ukuphefumla ezifana nezixhobo zokuphefumla ezizimeleyo (ii-SCBA) okanye izixhobo zokuphefumla ezibonelelweyo, ingakumbi kwiindawo ezinomngcipheko wokuvezwa ngumphunga we-cyanide.

• Ukuhlolwa nokugcinwa : Hlola rhoqo i-PPE ukuze ubone iimpawu zomonakalo okanye ukuguguleka. Tshintsha naziphi na izixhobo ezonakeleyo okanye ezigugileyo ngokukhawuleza ukuqinisekisa ukuba zisebenza kakuhle ekukhuseleni.

3. ImiGaqo yokuGcina

• Indawo Yokugcina Eyodwa : Gcina i-sodium cyanide kwindawo yokugcina ekhethekileyo, enomoya ococekileyo ehlukanisiweyo nezinto ezingahambelaniyo ezifana nee-asidi, ii-oxidizers, kunye nezinto ezinokutsha. Indawo yokugcina etshixiweyo enokufikelela okulinganiselweyo kufuneka isetyenziswe ukuthintela ukungena okungavumelekanga.

• Ukugcinwa Okwaneleyo : Sebenzisa izikhongozeli ezifanelekileyo zokugcina i-sodium cyanide. Ezi zikhongozeli mazivalwe ngokuqinileyo kwaye zenziwe ngezinto ezimelana nokugqwala yi-cyanide. Qinisekisa ukuba indawo yokugcina ineenkqubo zesibini zokugcinwa, ezifana neetreyi zokuchitheka okanye iidike, ukuthintela ukusasazeka kokuchitheka okanye ukuvuza.

4. Ukuphatha kunye neeNkqubo zokuTshintshela

• Imisebenzi Ecothayo Nelawulwayo : Xa udlulisela i-sodium cyanide ukusuka kwesinye isikhongozeli ukuya kwesinye okanye uyifaka kwinkqubo yokuyikhupha, yenza loo msebenzi kancinci nangononophelo ukuze unciphise ukuveliswa kothuli okanye umphunga. Sebenzisa izixhobo ezifanelekileyo zokudlulisa, ezifana neenkqubo ezivaliweyo okanye izixhobo zokudlulisa ezincediswa yi-vacuum, ukunciphisa umngcipheko wokuvezwa.

• Ukuthintela Ukuchitheka : Thatha amanyathelo okuthintela ukuchitheka ngexesha lokuphatha nokudlulisa. Ukuba ukuchitheka kwenzeka, qalisa ngoko nangoko indlela yokusabela kokuchitheka. Oku kungabandakanya ukuthintela indawo yokuchitheka, ukusebenzisa izinto ezifunxayo ukucoca ukuchitheka, kunye nokulahla izinto ezingcolisiweyo ngokwemigaqo yendawo.

5. Ukukhuselwa kokusiNgqongileyo

• Ulawulo lweNkunkuma : Phuhlisa isicwangciso esibanzi solawulo lwenkukuma senkunkuma equlethe i-sodium cyanide. Oku kubandakanya unyango olufanelekileyo kunye nokulahla i-leachate, i-tailings, kunye neminye imijelo yenkukuma. Iindlela zonyango zinokubandakanya i-oxidation yeekhemikhali, ukubola kwezinto eziphilayo, okanye ezinye iinkqubo ezifanelekileyo zokunciphisa ubuthi be-cyanide ngaphambi kokuba ilahlwe.

• Ukubeka iliso kunye nokuNika ingxelo : Qhubeka ubeka iliso kwimeko-bume ejikeleze indawo yokwemba ukuze ubone iimpawu zongcoliseko lwe-cyanide, njengasemhlabeni, emanzini, nasemoyeni. Xela rhoqo idatha yokubeka iliso kwimeko-bume kwiigunya ezifanelekileyo zolawulo njengoko kufuneka ngokomthetho.

6. Impendulo kaxakeka

• Izicwangciso zeNgxakeko : Misela izicwangciso ezineenkcukacha zokuphendula xa kukho ingxakeko ezigubungela iimeko ezinokubakho ezifana nokuchitheka, ukuvuza, imililo, kunye nokuvezwa ngengozi. Ezi zicwangciso mazibandakanye iinkqubo zokwazisa abo basabela xa kukho ingxakeko, ukukhupha abasebenzi, ukubonelela ngoncedo lokuqala, kunye nokugcina nokucoca indawo echaphazelekayo.

• Uqeqesho kunye nokuQeqesha : Qhuba uqeqesho rhoqo lokuphendula ngexesha likaxakeka kunye nokuqhelisa bonke abasebenzi ukuqinisekisa ukuba baqhelene neenkqubo zikaxakeka kwaye banokuphendula ngokufanelekileyo xa kukho isiganeko. Hlaziya izicwangciso zokuphendula ngexesha likaxakeka ngokusekelwe kwiziphumo zoqeqesho kunye naluphi na utshintsho ekusebenzeni kwemigodi okanye kwiimfuno zomthetho.

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.
