Shaanxi United Chemical: Muab Green Sodium Cyanide Solutions rau Kazakhstan

Nyob rau hauv lub tshav pob ntawm cov khoom siv tshuaj, Shaanxi United Chemical yeej ib txwm nyob rau hauv lub forefront ntawm kev lag luam nrog ib tug kws thiab lub luag hauj lwm duab. Tam sim no, peb zoo siab heev uas tuaj yeem muab cov khoom zoo Sodium Cyanide cov khoom rau Kazakhstan.

sodium cyanide, raws li ib qho tseem ceeb ntawm cov khoom siv raw, yog dav siv nyob rau hauv ntau qhov chaw lag luam, tshwj xeeb tshaj yog nyob rau hauv kev lag luam kub mining thiab beneficiation kev lag luam. Txawm li cas los xij, vim nws cov khoom tshwj xeeb, nws raug tswj hwm los ntawm tsoomfwv Suav. Peb kuj paub tob txog qhov muaj feem raug mob ntawm sodium cyanide mus rau ib puag ncig. Yog hais tias cov cyanide - uas muaj cov dej khib nyiab tsim nyob rau hauv qhov kub mining thiab cov txheej txheem tau txais txiaj ntsig tsis raug kho kom raug, nws yuav dhau los ua ib qho kev phom sij loj heev. Lub cyanide nyob rau hauv cov dej khib nyiab ntawm kub cyanidation nroj tsuag yog txiav txim los ntawm cov muaj pes tsawg leeg ntawm cov ore thiab cov kev khiav hauj lwm tej yam kev mob. Ntxiv nrog rau cyanide, nws kuj muaj tshuaj lom neeg xws li thiocyanate. Feem ntau ntawm cov thiocyanates no los ntawm cov txheej txheem aeration hauv kev tsim khoom lossis cov tshuaj tiv thaiv ntawm cyanide thiab sulfur atoms tsis ruaj khov thaum leaching. Tsis tas li ntawd, cov cyanide - muaj cov dej khib nyiab muaj ntau cov tshuaj lom neeg hlau cyanide complexes thiab cyanides. Yog li ntawd, Shaanxi United Chemical tsis yog tsuas yog cov khoom lag luam tab sis kuj yog tus kws tshaj lij ntawm Environmental Protection.

Environmental Protection Advantages

Hais txog kev tiv thaiv ib puag ncig, peb muaj cov txiaj ntsig zoo. Lub tuam txhab tau nqis peev ntau ntawm cov peev txheej hauv kev tshawb fawb thiab kev tsim kho thev naus laus zis, thiab muab kev txhawb nqa dav dav rau cov teeb meem ib puag ncig uas yuav tshwm sim thaum lub sijhawm tsim khoom, tsheb thauj mus los, khaws cia thiab siv Sodium cyanide. Peb pab neeg tshaj lij tuaj yeem pab cov lag luam hauv zos hauv Kazakhstan los tsim kom muaj kev tswj hwm ib puag ncig thiab txo cov pa phem los ntawm qhov chaw. Piv txwv li, nyob rau hauv cov txheej txheem ntau lawm, peb tau txais cov txheej txheem ntsuab synthesis los txhim kho cov khoom siv raw thiab txo cov khoom pov tseg.

Txoj Kev Kho Cyanide - muaj cov dej khib nyiab

Hauv kev kho mob ntawm cyanide - muaj cov dej khib nyiab hauv kev lag luam kub thiab cov txiaj ntsig kev lag luam, peb paub ntau yam kev paub tab thiab siv tau zoo:

• Txoj kev Alkaline Chlorination: Qhov no yog ib txoj hauv kev los rhuav tshem Cyanides nyob rau hauv cov dej khib nyiab ntawm kub cyanidation nroj tsuag thiab yog dav siv nyob rau hauv cov dej khib nyiab kho ntawm cyanide electroplating nroj tsuag, kub mine cyanidation nroj tsuag, kub cyanidation nroj tsuag thiab lwm yam units. Nws lub hauv paus ntsiab lus yog siv cov tshuaj chlorine, roj chlorine los yog tshuaj dawb huv los oxidize cov cyanide hauv cov dej khib nyiab rau hauv cov khoom tsis muaj tshuaj lom xws li carbon dioxide thiab nitrogen.

• Sulfur Dioxide - Cua Oxidation Method: Kuj tseem hu ua InCo txoj kev, nws tau tsim los ntawm American InCo Metals Company thaum xyoo 1980s. Txoj kev no siv cov sulfur dioxide thiab huab cua ua oxidants los oxidize cov cyanides hauv cov dej khib nyiab nyob rau hauv cov xwm txheej ntawm tooj liab - ion catalyst, tsim bicarbonate thiab ammonium ferrous sulfate. Nws tuaj yeem tsis tsuas yog tshem tawm cov dawb cyanide ions, molecular hydrogen thiab complex cyanides, tab sis kuj tshem tawm cov ferrocyanide complexes uas nyuaj rau tshem tawm los ntawm txoj kev chlorination, ua rau cov dej khib nyiab kho tau raws li cov qauv tso tawm.

• Hydrogen Peroxide Oxidation Method: Nws yog tsim rau kev kho qis - concentration cyanide - muaj cov dej khib nyiab. Nyob rau hauv qhov kev txiav txim ntawm ib tug tooj liab - ion catalyst ntawm ib tug alkaline pH nqi ntawm 10 - 11. hydrogen peroxide oxidizes cov cyanides los tsim cov tshuaj xws li oxides thiab ammonium ferrous sulfate. Ntawm lawv, hnyav hlau ions tsim hydroxide precipitates, thiab ferrocyanide ions thiab lwm yam hlau hnyav ions tsim ferrocyanide complex ntsev.

• Txoj kev ozone oxidation: Nws yog tsim rau kev kho mob dilute cyanide - muaj cov kua dej pov tseg. Ntawm alkaline pH tus nqi ntawm 11 - 12. ozone oxidizes cyanides los tsim bicarbonate thiab nitrogen. Txawm hais tias txoj kev no tsis tuaj yeem tshem tawm ferrocyanide complexes, nws muaj qhov zoo ntawm kev yooj yim thiab yooj yim. Tsis tas yuav yuav thiab thauj cov tshuaj, thiab tsuas yog xav tau lub tshuab hluav taws xob ozone los kho cov cyanide - muaj cov dej khib nyiab. Txawm li cas los xij, nws kuj muaj qhov tsis zoo ntawm kev siv hluav taws xob siab thiab cov nqi kho mob siab. Txhawm rau daws qhov teeb meem ntawm ferrocyanide complexes, Tinker Air Force Base hauv Tebchaws Meskas tau tsim cov txheej txheem ua ke ntawm ultraviolet photolysis thiab ozone txoj kev thiab ua tiav nws. Tom qab ntawd, txoj kev zoo sib xws O3 / photolysis kuj tau tsim.

Kev thauj mus los thiab kev ruaj ntseg cia

Hauv kev sib txuas ntawm kev thauj mus los, peb tau nruab nrog cov khoom siv tshuaj lom neeg kev thauj mus los thiab cov txheej txheem kev thauj mus los nruj kom ntseeg tau tias sodium cyanide tuaj txog ntawm qhov chaw nyab xeeb thaum txo qhov cuam tshuam rau ib puag ncig ntawm txoj kev. Nyob rau hauv cov nqe lus ntawm kev cia, peb muab scientific cia kev daws teeb meem thiab cov chaw los tiv thaiv kev huam yuaj xws li xau los ntawm polluting av thiab dej. Nyob rau hauv cov xwm txheej tsis tau npaj txhij, peb kuj muaj kev kho mob xwm txheej ceev thiab pab pawg uas tuaj yeem teb sai thiab txo qis ib puag ncig kev puas tsuaj.

Shaanxi United Chemical tau cog lus tias yuav ua haujlwm koom tes nrog cov koom tes hauv Kazakhstan kom ua tiav kev loj hlob ntsuab thiab ruaj khov thaum muab cov khoom lag luam zoo sodium cyanide. Peb ntseeg hais tias los ntawm peb cov kev siv zog, peb tuaj yeem pab txhawb rau kev lag luam kev lag luam ntawm Kazakhstan thiab tseem ntxiv kev lees paub rau kev tiv thaiv ib puag ncig hauv zos.
