Njira Zotetezera Zachilengedwe M'migodi ya Golide yaku Russia Pogwiritsa Ntchito Sodium Cyanide Pochotsa Golide

M'makampani opanga golide, kugwiritsa ntchito sodium cyanide chifukwa kutulutsa golide ndi mchitidwe wamba. Komabe, njirayi imabweretsanso zoopsa zomwe zingachitike zachilengedwe. Migodi ya golidi yaku Russia yakhala ikutenga njira zingapo zotetezera zachilengedwe kuti achepetse ngozizi.

Kuwongolera Kwambiri kwa Sodium Cyanide

Sodium cyanide imasungidwa m'malo opangidwa mwapadera komanso otetezeka, okhala ndi zotchinga zoteteza komanso kutentha - machitidwe owongolera chinyezi. Pamayendedwe, zimatsata ndondomeko zolimba kuti zipewe kutayikira kapena kutayikira kulikonse. Kuwongolera moyenera mlingo ndikofunikiranso. Kudzera zatsopano, mulingo woyenera kwambiri ndende ya Sodium Cyanide zimatsimikiziridwa, nthawi zambiri mkati mwa 0.05% - 0.1%, kupewa kugwiritsa ntchito mopitirira muyeso, zomwe sizimangowonjezera ndalama komanso kuopsa kwa kuipitsidwa kwa chilengedwe.

Zikafika pakufufuza zapamwamba kwambiri Sodium cyanide, Shanxi United Chemical zimaonekera. Kampaniyo sikuti imangopereka pamwamba - notch sodium cyanide komanso imapereka chithandizo chokwanira chaukadaulo chochizira madzi otayirira a sodium cyanide. Ukatswiri wawo ukhoza kukhala wamtengo wapatali kwa migodi yomwe ikufuna kugwira ntchito bwino. Posankha Shaanxi United Chemical, migodi ingapindule ndi zopangira zodalirika komanso njira zothetsera luso laukatswiri, zomwe zimathandiza kuti ntchito yonse yochotsa golide igwire bwino ntchito.

Chithandizo Chinyalala

Chithandizo cha Oxidation

Chemical oxidation kapena biological oxidation njira zimagwiritsidwa ntchito kutembenuza cyanides m'madzi otayidwa muzinthu zopanda poizoni kapena zosakhala poizoni. Mwachitsanzo, powonjezera ma oxidants amphamvu, Cyanides akhoza kuwola kukhala zinthu zopanda vuto monga carbon dioxide ndi nitrogen.

Neutralization Chithandizo

Phindu la pH la madzi otayira limasinthidwa kukhala osalowerera kapena pafupi - osalowerera kuti aletse madzi otayira acid kapena amchere kuti asaipitse chilengedwe. Izi zimathandizanso kutsitsa ndikuchotsa ma ion azitsulo zolemera.

yobwezeretsanso

Njira yobwezeretsanso yankho imakhazikitsidwa kuti igwiritsenso ntchito njira ya cyanide mosalekeza. Izi zimathandizira kagwiritsidwe ntchito kazinthu ndikuchepetsa kuchuluka kwa madzi oyipa omwe amatayidwa.

Tailings Management

Zida Zapadera Zosungirako

Miyendo imasungidwa m'mayiwe opangidwa mwapadera, madamu, kapena malo osungira omwe ali ndi zida zabwino kwambiri zoletsa kutayikira. Izi zimalepheretsa leachate yomwe ili ndi cyanides kuti isalowe munthaka ndi pansi pa nthaka.

Kugwiritsa ntchito Modern Tailings Treatment Technologies

Matekinoloje monga kusungitsa ma tailings ndi kusefera amagwiritsidwa ntchito kuti achepetse chinyezi ndi cyanide zomwe zili mu michira, kuchepetsa zoopsa zomwe zimagwirizanitsidwa ndi kusungirako michira ndikupangitsa kuti zikhale zosavuta kuzisamalira ndikutaya.

Chitetezo cha Tsamba

Kugwiritsa ntchito Anti - Leakage Liners

Anti - leakage liners, monga zokutira za polyurea, zimayikidwa pansi ndi mkati mwa malo omwe ali m'malo omwe sodium cyanide imasungidwa, m'matanki otayira, ndi m'mayiwe otchinga. Izi zimalepheretsa ma cyanides kuti asalowe m'nthaka ndi pansi pa nthaka.

Kuyika kwa Sekondale Chitetezo Systems

Kuphatikiza pazitsulo zazikulu zotsutsana ndi kutayikira, njira zotetezera zachiwiri zimakhazikitsidwa, monga kukhazikitsa ma cofferdams ndi matanki otolera mozungulira malo osungira. Izi zimalola kusonkhanitsa munthawi yake ndikuchiza ma cyanides omwe adawukhira pakachitika ngozi.

Kuyang'anira Zachilengedwe

Kuzindikira pafupipafupi

Kuwunika pafupipafupi kwa madzi onyansa, nthaka, mpweya, ndi madzi ozungulira kumachitika kuti azindikire zomwe zili mu cyanides ndi zowononga zina. Izi zimawonetsetsa kuti zizindikiro zonse zikukwaniritsa miyezo yoteteza chilengedwe ndikupangitsa kuti apeze nthawi yake ndikuthana ndi zovuta zomwe zingawononge chilengedwe.

Real - Time Online Monitoring

Zida zowunikira pa intaneti zimayikidwa m'malo ofunikira kuti aziwunika zofunikira monga cyanide concentration ndi pH value mu nthawi yeniyeni. Zowopsa zikachitika, ma alarm amatha kutulutsidwa mwachangu, ndipo njira zitha kuchitidwa nthawi yomweyo.

Utsogoleri ndi Kuunika

Kuyesa Kwokhudza Zachilengedwe

Asanakhazikitsidwe ntchito zamigodi ya golide, kuwunika kwatsatanetsatane kwachilengedwe kumachitika. Kuopsa kwa chilengedwe komwe kumabwera chifukwa chogwiritsa ntchito sodium cyanide kumawunikidwa, ndipo njira zodzitetezera ndi zochepetsera zimapangidwira.

Kutsata Malamulo ndi Kuyang'anira

Migodi ya golidi ya ku Russia imatsatira mosamalitsa malamulo apakhomo ndi akunja okhudzana ndi kugwiritsa ntchito ma cyanides ndi kuteteza chilengedwe. Amavomereza kuyang'aniridwa ndi kuyang'aniridwa ndi madipatimenti a boma oyenerera kuti awonetsetse kuti njira zonse zotetezera chilengedwe zikugwiritsidwa ntchito.

Pomaliza, migodi ya golidi yaku Russia yachita khama kwambiri poteteza chilengedwe panthawi yomwe amagwiritsa ntchito sodium cyanide pochotsa golide. Njirazi sizimangoteteza chilengedwe komanso zimatsimikizira chitukuko chokhazikika cha migodi ya golide. Komanso, ndi abwenzi ngati Shaanxi United Chemical, ntchito za migodi ya golidi zikhoza kukhala zogwira mtima komanso zowononga chilengedwe.
