United Chemical, I-TuXingSun Mining, kanye Nemayini Yegolide i-Henan Lingbao Ngokuhlanganyela Ukusungula Imayini Engenayo I-Cyanide

I-ejenti ye-Jinchan evuza igolide evumelana nemvelo iye yasetshenziswa embonini e-Wenyu Gold Mine e-Lingbao, eSifundazweni sase-Henan, ikakhulukazi ukuze kukhishwe izinto eziyigugu njengegolide. Le phrojekthi inokuqukethwe kwegolide okungamagremu angu-9 ngethani ngalinye kanye ne- Ikhabhoni ye-inorganic okuqukethwe ngu-10.94%. Inzuzo enkulu yale phrojekthi ukuhambisana kwayo nemvelo, okuhlanganisa ukusetshenziswa kwe-ejenti ye-Jinchan eco-friendly eco-friendly leaching ejenti esikhundleni se I-Sodium Cyanide. Le ndlela ayiqinisekisi kuphela ukusebenza kahle okuphezulu Ukukhishwa kwegolide kodwa futhi inciphisa umthelela wemvelo wenqubo yokucubungula insimbi.

Uma ukucoleka kokugaya kungu-0.074 mm, kunokuqukethwe okukhulu kuno-90%, ukugxiliswa kwe-pulp okungama-40%, umthamo we-lime ongu-3 kg/t, isikhathi sokulungiswa kwe-alkaline amahora angu-2, isilinganiso se-ejenti yegolide ye-Jinchan eco-friendly engu-600 g/t, kanye nesikhathi sokuvuza esingamahora angu-24. Izinga leaching ingafinyelela ku-95.60%. Uma kuqhathaniswa nokucwiliswa kwe-cyanide, izinga lokuvuza likhuphuka ngo-1.4%, ukusetshenziswa kwe-reagent kwehla ngo-200 g/ton, kanti isikhathi sokuvuza sifinyezwa ngamahora angaphezu kuka-12. Ngaphezu kwalokho, i-leaching Ukuhlaziywa kobuthi yezinsalela ze-eco-friendly ye-eco-friendly ye-ejenti yegolide yokucwilisa igolide ibonise ukuthi amanani e-leaching toxicity ye-cyanide, ithusi, i-lead, i-zinc, ne-arsenic emisileni angaphakathi kwemingcele evamile kazwelonke futhi angakhishwa ngokuqondile ngaphandle kwesidingo sokuqeda ubuthi.

Isici esibalulekile esivivinyweni esiyimpumelelo sephrojekthi ye-cyanidation egcwele umcako ukusetshenziswa kwe-ejenti ye-Jinchan eco-friendly leaching gold leaching. Lesi senzo se-leaching senzelwe ngokukhethekile ukwenza lula inqubo yokucwilisa nokumuncwa ngendlela eqhubekayo. I-ejenti ye-Jinchan leaching isebenzisa inqubo ye-leaching enezigaba ezine kanye nezinyathelo ezinhlanu zokumunca, iqinisekisa ukuthi ngisho nokuba khona kwekhabhoni ye-inorganic, umphumela wokucwiliswa kwegolide awuthinteki. Lokhu kuyimpumelelo ebalulekile yephrojekthi, njengoba kukhombisa ukuthi ezinye izindlela ezilungele imvelo zingasebenza njengezindlela zendabuko. Uma kuqhathaniswa nokucwiliswa kwe-cyanide, izinga le-leaching lingathuthuka ngo-1.4%, ukusetshenziswa kwama-reagents kuncishiswa ngamagremu angu-200 ngethani ngalinye, futhi isikhathi sokukhipha amanzi sifinyezwa ngamahora angu-12, okuholela emiphumeleni emihle yokukhipha amanzi kanye nezinzuzo ezibalulekile zezomnotho.

Ukufakwa esikhundleni kwe-sodium cyanide endaweni ye-Jinchan eco-friendly leaching gold leaching agent kukhombisa ukuzibophezela kwemayini Ukuvikelwa kwemvelo. I-sodium cyanide sekuyisikhathi eside iyindinganiso yemboni yokucwiliswa kwegolide, kodwa ubuthi bayo bubeka engcupheni enkulu emvelweni nempilo yabantu. Ngokuphambene, i-ejenti ye-Jinchan inikeza enye indlela ephephile futhi esimeme kakhudlwana, iqinisekisa ukuthi inqubo yokukhipha igolide ayifiki ngenani lokucekelwa phansi kwemvelo. Lokhu kushintshela ezindleleni ezilungele imvelo kuzuzisa i-ecosystem yendawo futhi kubeka isibonelo esihle embonini yezimayini ngobubanzi.

Iphrojekthi ye-cyanidation egcwele umcako eMayini Yegolide i-Wenyu iyingqopha-mlando ephawulekayo enkampanini yethu ekusunguleni imayini engenayo i-cyanide. Le phrojekthi igcizelela izindlela zokuvikela imvelo, kusetshenziswa ubuchwepheshe obusha obufana ne-Jinchan eco-friendly leaching gold leaching agent, okuholela ezindleleni ezisimeme nezinesibopho sokucubungula insimbi yegolide. Imayini yegolide i-Wenyu ibonisa ukuthi izakhi ezibalulekile njengegolide zingakhishwa ngokuphumelelayo ngaphandle kokulimaza indawo ezungezile, kubeke izinga elisha lemboni. Le phrojekthi iyakufakazela lokho Izimayini ezinomthwalo wemfanelo izenzo kanye nokuphathwa kwemvelo kungahambisana, kuhlahla indlela yekusasa elisimeme kwezezimayini.
