United Chemical, TuXingSun Mining, thiab Henan Lingbao Kub Mine Jointly tsim ib tug Cyanide-dawb Mine

Jinchan ib puag ncig tus phooj ywg kub leaching tus neeg sawv cev tau siv rau kev lag luam ntawm Wenyu Gold Mine hauv Lingbao, xeev Henan, tshwj xeeb tshaj yog rau kev rho tawm cov khoom muaj txiaj ntsig zoo li kub. Qhov project no muaj cov ntsiab lus kub ntawm 9 grams ib tuj thiab ib qho Cov pa roj carbon inorganic cov ntsiab lus ntawm 10.94%. Qhov zoo tshaj plaws ntawm qhov project no yog nws cov kev ua raws li ib puag ncig, suav nrog kev siv Jinchan eco-phooj ywg kub leaching tus neeg sawv cev los hloov Sodium Cyanide. Txoj kev no tsis tsuas yog ua kom muaj txiaj ntsig zoo Kub rho tawm tab sis kuj txo qhov cuam tshuam ib puag ncig ntawm cov txheej txheem ore.

Thaum cov kev sib tsoo fineness yog -0.074 hli, nrog cov ntsiab lus ntau dua 90%, lub pulp concentration ntawm 40%, ib tug txiv qaub npaum li cas ntawm 3 kg / t, alkaline pretreatment lub sij hawm ntawm 2 teev, ib tug Jinchan eco-phooj ywg kub leaching tus neeg saib xyuas ntau npaum li cas ntawm 600 g / t, thiab lub sij hawm leaching kub ntawm 24 teev. Leaching tus nqi tuaj yeem ncav cuag 95.60%. Piv nrog rau cyanide leaching, qhov leaching tus nqi nce 1.4%, reagent siv txo los ntawm 200 g / ton, thiab lub sij hawm leaching yog luv dua 12 teev. Tsis tas li ntawd, ib qho leaching Kev tshuaj ntsuam toxicity ntawm Jinchan eco-phooj ywg kub leaching tus neeg saib xyuas cov residue tau pom tias leaching toxicity qhov tseem ceeb rau cyanide, tooj liab, lead, zinc, thiab arsenic nyob rau hauv cov tailings yog tag nrho nyob rau hauv lub teb chaws tus qauv txwv thiab tuaj yeem tawm ncaj qha yam tsis tas yuav muaj kev tshem tawm detoxification.

Qhov tseem ceeb ntawm qhov kev sim ua tiav ntawm txoj haujlwm ua tiav ntawm cov txiv qaub cyanidation yog siv Jinchan eco-friendly kub leaching tus neeg saib xyuas. Cov leaching tus neeg sawv cev no tshwj xeeb tsim los pab txhawb txoj kev leaching thiab nqus dej kom ruaj khov. Lub Jinchan leaching tus neeg ua haujlwm siv plaub-theem leaching thiab tsib-theem nqus cov txheej txheem, kom ntseeg tau tias txawm tias muaj cov pa roj carbon inorganic, cov nyhuv kub leaching tsis cuam tshuam. Qhov no yog qhov tseem ceeb tshaj plaws rau txoj haujlwm, vim nws qhia tau tias cov kev hloov hauv eco-phooj ywg tuaj yeem ua tau zoo raws li cov txheej txheem ib txwm muaj. Piv nrog rau cyanide leaching, tus nqi leaching tuaj yeem txhim kho los ntawm 1.4%, kev noj cov tshuaj reagents yog txo los ntawm 200 grams ib tuj, thiab lub sij hawm leaching yog luv luv los ntawm 12 teev, ua rau muaj kev cuam tshuam zoo leaching thiab cov txiaj ntsig kev lag luam tseem ceeb.

Kev hloov pauv ntawm sodium cyanide nrog Jinchan eco-friendly kub leaching tus neeg saib xyuas qhia txog kuv txoj kev mob siab rau Kev tiv thaiv ib puag ncig. Sodium cyanide tau ntev ua tus qauv kev lag luam rau kub leaching, tab sis nws toxicity ua rau muaj kev pheej hmoo loj rau ib puag ncig thiab tib neeg kev noj qab haus huv. Hauv qhov sib piv, tus neeg sawv cev Jinchan muab kev nyab xeeb dua thiab muaj txiaj ntsig zoo dua, kom ntseeg tau tias cov txheej txheem rho tawm kub tsis tuaj yeem raug nqi ntawm ib puag ncig kev puas tsuaj. Qhov kev hloov pauv ntawm kev coj ua hauv eco-phooj ywg muaj txiaj ntsig zoo rau lub zej zog ecosystem thiab ua piv txwv zoo rau kev lag luam mining dav.

Txoj haujlwm puv-txiv qaub cyanidation ntawm Wenyu Gold Mine yog qhov tseem ceeb tshaj plaws rau peb lub tuam txhab hauv kev tsim cov mine tsis muaj cyanide. Qhov project no qhia txog kev tiv thaiv ib puag ncig, siv cov thev naus laus zis tshiab xws li Jinchan eco-phooj ywg kub leaching tus neeg saib xyuas, ua rau muaj kev ruaj ntseg thiab muaj lub luag haujlwm kub ore ua txoj hauv kev. Lub Wenyu Gold Mine qhia tau hais tias cov khoom muaj txiaj ntsig zoo li kub tuaj yeem muab rho tawm zoo yam tsis muaj kev puas tsuaj rau ib puag ncig, teeb tsa tus qauv tshiab rau kev lag luam. Qhov project no ua pov thawj tias Lub luag haujlwm mining kev coj noj coj ua thiab kev tswj hwm ib puag ncig tuaj yeem sib koom tes, ua rau txoj hauv kev rau lub neej yav tom ntej hauv kev tsuas.
