Ukwelashwa kwe-Cyanide ku-Gold Leaching Tailings

Ukusabalala kweCyanidation kanye Nengozi yeCyanide

I-Cyanidation isetshenziswa kabanzi yiningi lezimayini zegolide emhlabeni jikelele futhi cishe izohlala ivame eminyakeni ezayo. Kodwa-ke, i-Cyanide iyingozi kakhulu ekungcoleni. Ukuba khona kwayo emanzini angcolile kanye nasemasimini kungathinta kakhulu abantu kanye nemvelo. Ngakho-ke, kubalulekile ukulawula lokhu kungcola.

Inqubo yeCyanide Leaching kanye nemikhiqizo yayo

Ukukhuhla i-Cyanide kuguqula igolide libe yi- complexes ye-cyanide encibilikayo emanzini futhi okwamanje kuyindlela evame kakhulu futhi ephumelelayo yokukhipha igolide kuma-ore. Le nqubo idinga i-cyanide eningi ukuze kuthuthukiswe ukubuyiswa kwegolide, kukhiqizwe imfucuza equkethe i-cyanide ngesimo se-tailings namanzi. I-Cyanide yamahhala, umkhiqizo oyinhloko enqubweni ye-metallurgical, ibhekwa njengohlobo olunobuthi kakhulu lwe-cyanide njengoba ingabangela imiphumela eyingozi ngisho nasezilinganisweni eziphansi kakhulu. Ezinye izinhlobo ze-cyanide zingancibilika kalula zibe yi-cyanide yamahhala ngaphansi kwezimo ze-acidic.

Isidingo Sokwelapha i-Cyanide - equkethe i-Tailings

Ukuncishiswa kwemvelo kwe-cyanide ezingcebweni kuya ezingeni elingenabungozi eliphilayo kuthatha isikhathi eside. Ngakho-ke, izingcebweni eziqukethe i-cyanide kufanele ziphathwe ngaphambi kokuba zikhishwe emvelweni ukuze kugwenywe imiphumela emibi endaweni etholakele. Ukubola kwe-cyanide ezingcebweni zegolide kube ngenye yezinselele ezinkulu ezibhekene nezimayini zegolide emashumini eminyaka ambalwa edlule. Ngakho-ke, ukwelashwa okufanele kwe-cyanide ezingcebweni kuyadingeka ukuze kugwenywe noma kuncishiswe izinkinga zemvelo nezempilo.

Izindlela Zokwelapha Ezikhona Ze-Cyanide

Eminyakeni edlule, amasu amaningana ebhayoloji, ezemvelo, namakhemikhali, kanye ne-electrolytic oxidation kanye nezinye izindlela zokubola noma zokubuyisa i-cyanide, athuthukiswe ukwelapha izixazululo ze-cyanide. Njengamanje, amasu asetshenziswa kabanzi ekukhiqizweni kwezimboni kokubola kwe-cyanide afaka inqubo ye-INCO, inqubo ye-alkaline chlorination, inqubo ye-activated Carbon , inqubo ye-ozonation, inqubo ye-hydrogen peroxide oxidation, kanye nokubuyiselwa kwe-hydrogen cyanide. Izinqubo ze-INCO kanye ne-alkaline chlorination zisetshenziselwa ukususa i-cyanide enezinga eliphezulu kodwa azikwazi ukubola ngokuphelele i-cyanide. I-activated carbon ingamunca futhi ihlanganise i-cyanide kodwa ayikwazi ukuyibola. Izinqubo ze-ozonation kanye ne-hydrogen peroxide oxidation zisetshenziselwa ukwelapha i-cyanide enezinga eliphansi ngokungcola okuncane kwesibili, kodwa zibiza kakhulu. Ukubuyiselwa kwe-hydrogen cyanide kunganciphisa okuqukethwe kwe-cyanide kanye nezindleko kodwa akuhlangabezani nezidingo zokugcwalisa i-backings.

I-Backfilling Technology kanye noCyanide Removal Research

Ubuchwepheshe bokugcwalisa i-backfilling buyindlela engcono kakhulu yokuthi izimayini zidlule ezinkingeni zezinsizakusebenza, imvelo, kanye nokuphepha. Kodwa-ke, izinto eziyingozi njengezinto zensimbi ezisele kanye nezinyibilikisi zegolide - i-leaching tailings kufanele ziphathwe kahle ngaphambi kokugcwalisa i-backfilling ukuze kuvinjelwe ukungcoliswa kwamanzi angaphansi komhlaba. Ucwaningo lokususa i-cyanide lugxile kakhulu emanzini angcolile ezimbonini. Ucwaningo lokususa i-cyanide ku-leaching tailings zegolide - leaching, okuhlanganisa amanzi angcolile kanye ne-tailings, lusenomkhawulo. Ukwakheka kwamaminerali kwe-ore yegolide kuyinkimbinkimbi kakhulu, futhi izinto zamakhemikhali ezifana ne-cyanide, i-Activated Carbon powder, kanye ne-hydrogen peroxide zengezwa enkambisweni yokuzuza, okwenza ukwakheka kwe-tailings kube nzima nakakhulu. Iningi le-cyanide esele ku-tailings linamathele kakhulu ebusweni bamaminerali, futhi inani elincane kuphela le-cyanide yamahhala kanye ne-hydrolyzed complex cyanide elingangena ku-leachate. Ngakho-ke, kubalulekile ukuhlola izindlela eziphumelelayo zokususa i-cyanide.

Ubunkimbinkimbi be-CN⁻ Ukuwohloka kanye Neziqondiso Zocwaningo Lwesikhathi esizayo

Ukubola okufanele kwe-CN⁻ kuyinqubo eyinkimbinkimbi. Kudinga inhlanganisela yezindlela eziningi zokuthuthukisa ukusebenza kahle kokwelashwa nokucabangela umnotho wokwelapha. Ukusebenzisa izindlela ezihlanganisiwe zokususa i-cyanide kuyisiqondiso esithembisayo socwaningo lwangomuso.
