Njira ya Carbon Slurry Yochotsa Golide: Kupeza Mtengo Wapamwamba wa 94% Wobwezeretsa Golide

Mu gawo la migodi ndi kutunga golide, kuchita bwino komanso kuchira mwachangu ndikofunikira kwambiri. Njira ya Carbon Slurry yakhala njira yotsogola, yotchuka chifukwa cha kuthekera kwake kopeza Chiwongola dzanja chochuluka chobwezeretsa golide mpaka 94%. Nkhaniyi ikufotokoza zovuta za njira ya Carbon slurry, pofufuza zabwino zake, njira zogwirira ntchito, ndi kufunika kwake m'makampani amakono opangira migodi yagolide.

Kumvetsetsa Njira ya Carbon Slurry

Njira ya carbon slurry ndi njira yomwe imagwiritsidwa ntchito kwambiri pochotsa golide ku miyala. Zimaphatikizapo masitepe okonzedwa bwino omwe amathandizira kulekanitsa bwino kwa golide ndi mchere wozungulira.

Kukonzekera Ore

Njirayi imayamba ndikuchotsa golide - kukhala ndi miyala kuchokera mumgodi. Mwalawo amaupititsa kumalo opangira zinthu, kumene amakauphwanya ndi kuwapera. Njira imeneyi ndi yofunika kwambiri chifukwa imachepetsa miyalayi kuti ikhale yosasunthika, ndikuwonjezera malo omwe amapezeka kuti apangidwe ndi mankhwala. Mwala wophwanyidwa ndi pansi umasakanizidwa ndi madzi kuti apange slurry, yomwe imakhala yokonzekera gawo lotsatira la ndondomekoyi.

Cyanidation

Kusakaniza kwa cyanide ndi gawo lofunika kwambiri pakupanga carbon slurry. Pa gawoli, yankho la cyanide limawonjezeredwa ku slurry. Cyanide imayanjana ndi golide mu miyala, ndikusandutsa golide wosungunuka - cyanide complexes. Izi zimachitika m'matanki akuluakulu ogwedezeka, kuonetsetsa kuti yankho la cyanide limasakanikirana bwino ndi slurry ya miyala, zomwe zimapangitsa kuti golide atuluke kwambiri.

Adayambitsa Carbon Adsorption

Golideyo akasinthidwa kukhala ma soluble complexes, activated carbon imawonjezedwa ku slurry. Mpweya wopangidwa ndi activated uli ndi porous kwambiri, womwe umapereka malo akuluakulu owonetsera. Mafakitale agolide - cyanide amakopeka ndi mpweya wopangidwa ndi kaboni, komwe amakongoletsedwa. Njirayi imasankha kwambiri, pomwe mpweya wopangidwa ndi kaboni umakonda kutsatsa golide - cyanide complexes kuposa zinthu zina mu slurry. Kutengeka kwa golide pa carbon activated ndi njira yakuthupi - mankhwala, kumene golide - cyanide ayoni amagwiridwa pamwamba pa mpweya kupyolera mu mphamvu zosiyanasiyana ndi kuyanjana kwa mankhwala ndi magulu ogwira ntchito pa carbon.

Kupatukana kwa Kaboni Wodzaza

Pambuyo pa njira ya adsorption, carbon activated, yomwe tsopano yodzaza ndi golidi, iyenera kupatulidwa ndi slurry yotsalayo. Izi zimatheka pogwiritsa ntchito zowonetsera kapena njira zina zolekanitsa. Mpweya wopatulidwa wopatulidwa umakhala wokonzekera sitepe yotsatira ya ndondomekoyi, yomwe imaphatikizapo kubweza golide ku carbon.

Kubwezeretsa Golide kuchokera ku Carbon Yodzaza

Pali njira zingapo zopezera golide kuchokera ku kaboni wodzazidwa. Njira imodzi yodziwika bwino ndi desorption, pomwe ma complexes a golide ndi cyanide amachotsedwa mu kaboni pogwiritsa ntchito njira yotentha komanso yokhazikika ya Sodium Cyanide ndi sodium hydroxide. Kenako yankho la golide ndi cyanide lochotsedwa limayikidwa mu electrolysis kapena njira zina kuti golideyo agwere mu mawonekedwe ake achitsulo. Njira ina ndi kusungunula mwachindunji kaboni wodzazidwa, komwe kaboni amawotchedwa mu uvuni, ndipo golideyo amatengedwa kuchokera ku phulusa lomwe limatuluka.

Ubwino wa Carbon Slurry Process

High Gold Recovery Rate

Njira yochotsera golide kuchokera ku chitsulo cha carbon ndi yothandiza kwambiri pochotsa golide kuchokera ku chitsulo cha carbon, ndipo kuchuluka kwa golide komwe kumapezeka mpaka 94%. Kuchuluka kumeneku kumabwera chifukwa cha kuphatikiza kwa njira ya Cyanidation , yomwe imasungunula golide bwino, komanso kusankhidwa kwa golide ndi cyanide complexes pogwiritsa ntchito carbon yogwira ntchito. Kutha kubwezeretsa golide wambiri womwe ulipo mu chitsulo cha carbon ndi mwayi waukulu, chifukwa kumawonjezera phindu la ntchito yofufuza migodi.

Kukwanira kwa Mitundu Yosiyanasiyana ya Ores

Njira ya carbon slurry ndi yosunthika ndipo ingagwiritsidwe ntchito pamitundu yambiri ya golide - ore yokhala ndi golide, kuphatikizapo ores otsika kwambiri, ore oxidized, ndi ores omwe ali ndi mineralogy yovuta. Kusinthasintha kumeneku kumapangitsa kukhala chisankho chokondedwa pa ntchito zambiri za migodi ya golide padziko lonse lapansi, chifukwa zimathandiza kuchotsa golide kuchokera ku miyala yomwe ingakhale yovuta kapena yopanda ndalama kuti igwiritsidwe ntchito pogwiritsa ntchito njira zina.

Njira Yosavuta

Poyerekeza ndi njira zina zachikhalidwe zochotsera Golide , njira yochotsera kaboni imakhala ndi njira yosavuta. Imachotsa kufunikira kwa njira zovuta komanso zokwera mtengo zolekanitsa madzi olimba zomwe nthawi zambiri zimafunika pazinthu zina. Kugwiritsa ntchito kaboni woyatsidwa kuti ulowetse mwachindunji kuchokera ku slurry kumachepetsa kuchuluka kwa njira zokonzera, zomwe zimapangitsa kuti ndalama zogwirira ntchito zichepe komanso ndalama zogwirira ntchito.

Ubwino Wachilengedwe

Pankhani ya chilengedwe, njira ya carbon slurry ili ndi ubwino wambiri. Kugwiritsiridwa ntchito kwa cyanide m’malo olamuliridwa ndi okhalamo, pamodzi ndi njira zoyendetsera zinyalala zoyenera, kumathandiza kuchepetsa kutulutsidwa kwa zinthu zovulaza m’chilengedwe. Kuonjezera apo, kubweza golide wokwera kumatanthauza kuti miyala yochepa iyenera kukonzedwa kuti ipeze golide wofanana, kuchepetsa chilengedwe chonse cha ntchito ya migodi.

Mtengo - Kuchita bwino

Kuphatikizika kwa kuchuluka kwa kuchira, njira yosavuta, komanso kuchepa kwachilengedwe kumapangitsa kuti njira ya carbon slurry ikhale yotsika mtengo. Ngakhale kuti pamakhala ndalama zoyamba zoyendetsera ntchito yokonza makinawo, ndalama zogwirira ntchito zanthawi yayitali ndizochepa. Kukwanitsa kuchotsa golide kuchokera kuzinthu zosiyanasiyana kumawonjezeranso phindu la ntchito ya migodi, chifukwa zimathandiza kugwiritsa ntchito zinthu zomwe poyamba zinkaganiziridwa kuti ndizochepa.

Mapulogalamu mu Gold Mining Industry

Njira ya carbon slurry imagwiritsidwa ntchito kwambiri m'makampani akuluakulu a migodi ya golide padziko lonse lapansi. Migodi ya m'madera monga Africa, Australia, ndi North America nthawi zambiri imagwiritsa ntchito njira imeneyi pochotsa golide m'mabwinja awo. Mwachitsanzo, m'migodi ina ya ku Africa, njira ya carbon slurry yakhala ikugwiritsidwa ntchito bwino pokonza miyala ya golide yotsika kwambiri, yomwe ili ndi okosijeni kwambiri, zomwe zachititsa kuti golide yemwe poyamba anali wopanda chuma atengedwenso. Ku Australia, ndondomekoyi imagwiritsidwa ntchito m'migodi yokhala ndi matupi ovuta a ore, kumene kusinthika kwake ndi kuchira kwake kwakhala kofunikira kwambiri.

Kutsiliza

Njira ya carbon slurry yochotsa golide imapereka zabwino zambiri, ndi kuthekera kwake kukwaniritsa chiwongola dzanja chokwanira cha golide mpaka 94% kukhala chinthu chodziwika bwino. Kupyolera mu kuphatikiza kwa cyanidation, activated carbon adsorption, ndi njira zolekanitsa zogwira mtima, njirayi yasintha kwambiri migodi ya golide. Kusinthasintha kwake, kuphweka, ubwino wa chilengedwe, komanso mtengo wake - kumapangitsa kuti ikhale chisankho chokondedwa kwa ogomba golide padziko lonse lapansi. Pamene kufunikira kwa golidi kukukulirakulirabe, njira ya carbon slurry mosakayikira idzatenga gawo lalikulu pakuwonetsetsa kuti chitsulo chamtengo wapatalichi chikuchotsedwa mokhazikika komanso moyenera.
