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

Pamalo a migodi ndi kuchotsa golide, kuchita bwino komanso kuchira kwapamwamba ndikofunikira kwambiri. The Njira ya Carbon Slurry yatulukira ngati njira yotsogola, yodziwika bwino chifukwa cha kuthekera kwake kokwaniritsa zonse zochititsa chidwi Mtengo Wobwezeretsa Golide mpaka 94%. Nkhaniyi ikufotokoza zovuta za Carbon njira yothira matope, kufufuza ubwino wake, njira zogwirira ntchito, ndi kufunika kwake mumakampani amakono opangira migodi ya golide.

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

Cyanidation ndi gawo lofunikira munjira ya carbon slurry. Mu gawo ili, yankho la cyanide akuwonjezeredwa ku slurry. Cyanide imakhudzidwa ndi golide mu ore, ndikusandulika kukhala golide wosungunuka - cyanide complexes. Izi zimachitika m'matangi akuluakulu osokonezeka, kuwonetsetsa kuti yankho la cyanide limasakanikirana bwino ndi ore slurry, kukulitsa kutulutsa kwa golide.

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 carbon yodzaza. Njira imodzi yodziwika bwino ndi desorption, pomwe ma complexes a golide - cyanide amachotsedwa mu kaboni pogwiritsa ntchito njira yotentha yokhazikika. Sodium Cyanide ndi sodium hydroxide. The desorbed golide - cyanide yankho ndiye pansi electrolysis kapena njira zina kuti precipitate golide mu mawonekedwe ake zitsulo. Njira ina ndiyo kusungunula kaboni wodzaza, kumene mpweya wa carbon umatenthedwa mu ng'anjo, ndipo golide amachotsedwa ku phulusa lake.

Ubwino wa Carbon Slurry Process

High Gold Recovery Rate

Njira ya carbon slurry ndiyothandiza kwambiri kubweza golide ku miyala yamtengo wapatali, ndipo golide wokwanira kuchira mpaka 94%. Kuchuluka kwa kuchira kumeneku kumatheka chifukwa cha kuphatikiza kwa Cyanidation Njira, yomwe imasungunula bwino golide, ndi kusankha kosankhidwa kwa golide - cyanide complexes ndi carbon activated. Kukhoza kubwezeretsa gawo lalikulu la golidi lomwe likupezeka muzitsulo ndilopindulitsa kwambiri, chifukwa limakulitsa phindu lachuma pa ntchito ya 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 miyambo ina Kutulutsa Golide Njira, njira ya carbon slurry ili ndi ndondomeko yosavuta. Zimathetsa kufunikira kwa zovuta komanso zotsika mtengo zolimba - njira zolekanitsa zamadzimadzi zomwe nthawi zambiri zimafunikira munjira zina. Kugwiritsidwa ntchito kwa carbon activated for adsorption mwachindunji kuchokera ku slurry kumachepetsa kuchuluka kwa masitepe opangira, zomwe zimapangitsa kuti ndalama zichepetse 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.
