Inqubo Yokusebenzisa Kabusha Kwesulphur, Iron, Negolide kusuka ku-Cyanide Tailings

Ukusabalala kanye Nezingqinamba Zenqubo Ye-Cyanidation

The Inqubo ye-cyanidation unesikhundla esiphezulu ekukhishweni kwegolide emhlabeni jikelele kanye ne-metallurgy. Kunconywa kakhulu ngezinzuzo eziningi. Izinga layo eliphezulu lokuthola kabusha liqinisekisa ukukhishwa kwegolide okuphezulu. Ukuzivumelanisa nezimo kwenqubo ezinhlotsheni ze-ore ezihlukahlukene kuyenza ibe nezinto ezihlukahlukene. Ngokusebenza, ilula, futhi iyabiza - iyasebenza, okuyinzuzo enkulu ezinkampanini zezimayini. Ukwengeza, ivimbela ukulahlekelwa ngesikhathi sokuthuthwa kwensimbi yegolide. Kodwa-ke, i-drawback ephawulekayo yale nqubo ukukhiqizwa kwenani elikhulu Iziqu ze-cyanide.

Izingozi Zemvelo Nezokuphepha Ezidalwa I-Cyanide Tailings

Ukulahlwa kwe i-cyanide izinsalela zethula izinselelo ezinzima zemvelo nokuphepha. Lezi zinsika zithatha umhlabathi omkhulu, okuholela ekumoshweni kwemithombo yomhlaba eyigugu. Okubaluleke nakakhulu, zimosha imithombo yamaminerali ebalulekile ebingase isetshenziswe ngenye indlela. Ubuthi obuyinsalela emisileni ye-cyanide bungangcolisa imifula nenhlabathi, buphazamise kakhulu ibhalansi yemvelo. Ngaphezu kwalokho, amadamu anensalela ahlobene nemisila ye-cyanide adala izingozi zokuphepha ezingaba khona. Ukwehluleka kwamadamu kungadala imiphumela eyinhlekelele, kubeke ukuphila nempahla engozini.

Izindlela Zamanje Nemikhawulo yazo

Naphezu kokuhlukaniswa njengemfucuza, imisila ye-cyanide inamandla amakhulu okuthola kabusha izinsiza. Njengamanje, umkhuba ojwayelekile uwukucebisa isibabule emisileni ye-cyanide futhi uyisebenzise njengento eluhlaza ekukhiqizeni i-sulfuric acid. Kamuva, i-slag ewumphumela isetshenziswa ngokuqondile njenge-iron powder. Nokho, le ndlela inemikhawulo emibili emikhulu. Okokuqala, i-iron powder iqukethe igolide. Lokhu kunciphisa ingqikithi Ukusetshenziswa kwemithombo isilinganiso kanye nembuyiselo yezomnotho. Okwesibili, izinga lensimbi le-slag liphansi kakhulu. Uma kubhekwa ukuthi izinga lensimbi lilingana ngokuqondile nenani le-metallurgical, ukwenza ngcono izinga lensimbi kungathuthukisa ngokuphawulekayo ukusebenza kahle kokuncibilikisa.

Ukubaluleka Kokusetshenziswa Okuphezulu Kwevelu Yezinsalela Ze-Cyanide

Ukusungula indlela yokusebenzisa inani eliphezulu lesulphur, insimbi, negolide kumasisila e-cyanide kubaluleke kakhulu. Le ndlela yokusungula ihlose ukukhulisa inani lezomnotho lemisila ye-cyanide. Ngokwenza kanjalo, ibhekana ngokuphumelelayo nezinselele zemvelo nezomnotho. Imele isinyathelo esibalulekile esibheke entuthukweni esimeme embonini yezimayini, enikeza isixazululo esiphumelelayo sokulondoloza izinsiza kanye nokukhula komnotho.
