Kumvetsetsa Njira Yochotsera Golide ya All-Slime Cyanidation mu Migodi ya Golide

Mu ufumu wa kutulutsa golide, zonyansa zonse cyanidation ndondomekoyi ndi njira yofunika kwambiri komanso yovomerezeka kwambiri yopezera golide ku miyala yamtengo wapatali. Njirayi ndi yothandiza kwambiri pochiza zinthu zokhala ndi golidi wopangidwa bwino kwambiri pomwe golidi amagawika m'matrix a ore mu tinthu tating'onoting'ono. Cholemba ichi chabulogu chidzasanthula mwatsatanetsatane mwatsatanetsatane wa njira yochotsera golide wa cyanidation, ndikuwunikira kufunikira kwake, masitepe ogwirira ntchito, ndi zofunikira zake.

Kufunika kwa All-Slime Cyanidation

Njira yopangira matope onse a cyanidation yasinthiratu kuchotsedwa kwa golide pothandizira kubweza golide kuchokera mumiyala yomwe m'mbuyomu inkaonedwa kuti ndiyopanda ndalama. Zimalola kutulutsa golide kuchokera ku miyala yamtengo wapatali, komanso kuchokera kuzinthu zovuta zomwe zimakhala ndi mchere wotsutsa. Posungunula golide mu a cyanide yankho, njirayi imatha kukwaniritsa mitengo yayikulu yobwezeretsa golide, ndikupangitsa kuti ikhale chisankho chokondedwa pantchito zambiri zamigodi ya golide padziko lonse lapansi.

Njira Zogwirira Ntchito za All-Slime Cyanidation Process

Kukonzekera Ore

Gawo loyamba mu njira yonse ya cyanidation yamatope ndikukonzekera ore. Miyala yokhala ndi golidi imaphwanyidwa ndikuphwanyidwa kukhala ufa wabwino kuti awonjezere malo omwe amapezeka kuti asungunuke golide. Izi zimachitika pogwiritsa ntchito kuphatikiza kwa ma crushers, grinders, ndi zowonera kuti mukwaniritse kukula kwa tinthu komwe mukufuna. Miyala yamtengo wapatali, kapena "slime," imatsukidwa kuchotsa zonyansa zilizonse ndikuzikonzekera kuti cyanidation ichitike.

Cyanidation

Mwala ukakonzedwa, umasakanizidwa ndi madzi a cyanide mumndandanda wa akasinja osokonezeka. Yankho la cyanide limakumana ndi golide mu ore, kupanga chosungunuka chagolide cha cyanide. Izi zimatheka chifukwa cha kukhalapo kwa okosijeni, womwe umalowetsedwa mu akasinja kudzera mu mpweya. Kutalika kwa njira ya cyanidation kumatha kusiyanasiyana kutengera mtundu wa ore komanso kuchuluka kwa golide komwe mukufuna, koma nthawi zambiri kumakhala kuyambira maola angapo mpaka masiku angapo.

Kupatukana Kolimba-Zamadzimadzi

Pambuyo cyanidation ndondomeko watha, chifukwa slurry pansi olimba-zamadzimadzi kulekana. Izi zimachitika pogwiritsa ntchito kuphatikiza zowuma, zosefera, ndi ma centrifuges kuti alekanitse michira yolimba kuchokera ku mimba ya leach solution (PLS), yomwe imakhala ndi golide wosungunuka. Michira yolimba imatayidwa m'malo osungiramo michira, pomwe PLS imatumizidwa kuti ipitirire kukonzanso golideyo.

Gold Recovery

Gawo lomaliza la njira yochotsera golide kuchokera ku matope onse ndi kubwezeretsanso golide. Pali njira zingapo zomwe zingagwiritsidwe ntchito pobwezeretsa golide kuchokera ku PLS, kuphatikizapo yogwiritsidwa ntchito. Carbon Kulowetsa madzi m'thupi, kusinthana kwa ma ion, ndi kugonjetsa ma electrowinning. Kulowetsa madzi m'thupi pogwiritsa ntchito activated carbon ndiyo njira yomwe imagwiritsidwa ntchito kwambiri, pomwe PLS imadutsa m'mizere yambiri yodzazidwa ndi Carbon WoyendetsaGolide wa cyanide umalowa pamwamba pa kaboni, pomwe yankho lotsalalo limabwezeretsedwanso ku njira yobwezeretsanso cyanidation. Kenako kaboni wodzazidwayo amachotsedwa golideyo pogwiritsa ntchito yankho lotentha la cyanide, ndipo golideyo amabwezedwanso pogwiritsa ntchito electrowinning kapena smelting.

Mfundo Zofunika

Ngakhale njira ya cyanidation yonse ndi njira yabwino yochotsera golidi, imabweretsanso zovuta zingapo komanso malingaliro. Chimodzi mwazinthu zomwe zimadetsa nkhawa kwambiri ndikugwiritsa ntchito cyanide, yomwe ndi mankhwala oopsa kwambiri. Kusamalira bwino, kusungirako, ndi kutaya cyanide ndikofunikira kuti muchepetse kuopsa kwa chilengedwe ndi thanzi lokhudzana ndi kugwiritsidwa ntchito kwake. Kuganiziranso kwina ndikuchiza michira yolimba, yomwe imatha kukhala ndi cyanide yotsalira ndi zonyansa zina. Kuwongolera kwa michira ndikofunikira kwambiri kuti tipewe kutulutsa zonyansazi m'chilengedwe ndikuwonetsetsa kukhazikika kwanthawi yayitali kwa malo osungiramo michira.

Kuphatikiza apo, njira ya cyanidation ya slime yonse imafuna ndalama zambiri zogulira zida ndi zomangamanga, komanso kukwera mtengo kwamagetsi, mankhwala, ndi ntchito. Ndalamazi zikhoza kukhudza kwambiri chuma cha ntchito ya migodi ya golide, ndipo kuganizira mozama kuyenera kuperekedwa pa kusankha njira yoyenera ndi zipangizo zochepetsera ndalamazi.

Kutsiliza

Dongosolo lonse la cyanidation ndi njira yovuta koma yothandiza kwambiri pochotsa golide kuchokera ku miyala yamtengo wapatali ya golide. Pomvetsetsa masitepe ogwirira ntchito, mfundo zazikuluzikulu, ndi zovuta zomwe zimagwirizanitsidwa ndi ndondomekoyi, makampani oyendetsa migodi ya golide akhoza kupanga zisankho zomveka bwino za momwe angagwiritsire ntchito ndikukwaniritsa ntchito zawo zobwezeretsa golide. Pamene kufunikira kwa golidi kukukulirakulirabe, njira yonse ya cyanidation ya slime idzakhalabe njira yofunikira yokwaniritsira zofunazi, komanso kuthana ndi mavuto a chilengedwe ndi chikhalidwe cha anthu okhudzana ndi migodi ya golide.
