Kutulutsa Golide ku Oxidized Gold Ore

Mwachilengedwe, golidi sachita ndi mpweya kuti apange ma oxides ngati chitsulo kapena mkuwa. Kaya akwiriridwa m’manda, mchenga, kapena pansi pa nyanja kwa zaka zikwi zambiri, miyala ya golide, njere, ndi mipiringidzo ikupitirizabe kuwala.

Ndiye, ngati golide sakhala ndi oxidize, kwenikweni ndi chiyani oxidized golide miyala?

Kumvetsetsa Oxidized Gold Ores

Oxidized golide ore amatanthauza golide-wokhala ndi miyala yopangidwa kudzera mu njira zachilengedwe za okosijeni, osati ma oxides agolide.

Miyala yotereyi imakhala ndi golidi limodzi ndi oxides zitsulo monga chitsulo, mkuwa, ndi manganese. Maminolo akuluakulu ndi limonite ndi pyrite, okhala ndi sulfide pang'ono kapena opanda, koma amaphatikizanso mchere wokhazikika ngati golide - wokhala ndi chitsulo cha hydroxides kapena hydrated iron oxides, pamodzi ndi quartz.

Kutentha kwapamtunda kumasintha mchere wa sulfide kukhala ma oxides ndi ma hydroxide, golide wokhoza kuyikidwa mu hematite, goethite, kapena limonite.

Oxidized gold ore nthawi zambiri amawoneka achikasu mpaka bulauni ndipo amakhala ndi mawonekedwe otayirira. Ndi zofunika zopangira kupanga golide.

Momwe Mungatulutsire Golide ku Oxidized Gold Ore?

Mu golide wopangidwa ndi okosijeni, golide wambiri amakhala mkati mwa mchere waukulu wa gangue ndi ming'alu ya zitsulo zotayidwa. Kukula kwa tinthu tagolide kumasiyana kwambiri, ndipo kapangidwe ka mchere ndi kosavuta.

Asanayambe kuphwanya ndi kupera, kupangira golide ndi chotchinga cha trommel ndi gawo lofunikira pakuwongolera bwino kwabwino, makamaka kwa oxidized golide wokhala ndi dongo.

Pambuyo pake, kutulutsa golide zitha kuchitidwa pogwiritsa ntchito njira monga kulekanitsa mphamvu yokoka, cyanidation, kapena kuchuluka kwa magazi.

Khwerero 1: Kuphwanya Ore

Kuphwanya kumachepetsa kukula kwa oxidized ore golide ndipo nthawi zambiri kumachitika pogwiritsa ntchito njira youma ndi magawo awiri kapena atatu otsatizana: pulayimale, sekondale, ndi maphunziro apamwamba.

Pambuyo kuphwanya, chotchinga chogwedezeka chimagwiritsidwa ntchito kuyika golide wopangidwa ndi okosijeni. Tizigawo tating'onoting'ono timadutsa pazenera pomwe tinthu tating'onoting'ono timatsalira pazenera ndikubwezedwa kuti tiphwanyidwenso.

Gawo 2: Kugaya Ore

Kugaya kumatulutsa golide kuchokera ku mchere wa gangue mu miyala ya golide wopangidwa ndi okosijeni, zomwe zimapangitsa kuti pakhale mikhalidwe yabwino kuti apindule nawo. Zida zogayira wamba zimaphatikizapo mphero za mpira ndi mphero zonyowa.

Gawo 3: Kupindula kwa Ore

Oxidized ore ore beneficiation ndi njira yovuta komanso yovuta. Njira zosiyanasiyana zochotsera zingasankhidwe molingana ndi chikhalidwe cha miyala ndi mawonekedwe a golide. Zotsatirazi ndi njira zingapo zopezera phindu:

1. Kupatukana kwa Mphamvu yokoka

Kupatukana kwa mphamvu yokoka ndi njira yakuthupi yomwe imagwiritsa ntchito kusiyana kwa mphamvu yokoka pakati pa miyala ya golide ndi mchere wa gangue kuti ulekanitse.

Zida zomwe zimagwiritsidwa ntchito nthawi zambiri zolekanitsa golide wa ore yokoka zimaphatikizanso tebulo logwedeza, chute yozungulira, jig, ndi zina.

2. Cyanidation

Njira ya cyanidation ndiyo njira yomwe imagwiritsidwa ntchito kwambiri popanga golide. Ndizoyenera migodi yaing'ono ndi yapakatikati ya ore oxidized golide, makamaka omwe ali ndi kukula kwa tinthu tating'ono komanso apamwamba kwambiri.

Pambuyo popera, golide wothira okosijeni umasakanizidwa ndi cyanide njira, ndi golide kusungunuka mu madzi kudzera leaching reaction, ndiyeno golide anachira ndi adamulowetsa mpweya adsorption kapena zinki mpweya.

Cyanidation imapereka mitengo yayitali yobwezeretsa golide komanso kugwiritsidwa ntchito kwakukulu koma kumakhudza ntchito zovuta komanso zokwera mtengo chifukwa chofuna kuyang'anira zinyalala za cyanide.

3. Mulu Leaching

Milu ya leaching ndi yoyenera kwa otsika - kalasi kapena zazikulu chunks wa oxidized golide ore, nthawi zambiri popanda akupera.

Akaphwanyidwa, golide wonyezimira amawunjikidwa pamalo otayirapo - umboni mulu wa leaching pad, kupanga mulu wa miyala. Mankhwala a cyanide amawapopera pamwamba pa muluwo kuti asungunuke golideyo, yemwe amachotsedwa mu njira ya leach.

Njirayi imakhala ndi ndalama zotsika mtengo, ntchito yosavuta, kusinthasintha kwakukulu, ndipo ndiyoyenera kutulutsa miyala yagolide yotsika. Komabe, pamafunika kukula kwake kwa tinthu tating'ono, chifukwa tinthu tating'onoting'ono tating'onoting'ono tingakhudze leaching.

Izi ndi njira zitatu zazikulu zopangira oxidized ore golide. Kwa ore oxidized pang'ono, kulekanitsa mphamvu yokoka ndi cyanidation nthawi zambiri zimaphatikizidwa. Mu ore oxidized mokwanira, golide wobiriwira nthawi zambiri amapezedwa pogwiritsa ntchito kulekanitsa mphamvu yokoka, pomwe tinthu tating'ono ta golide timathiridwa ndi agitation cyanidation, ndipo tinthu tating'onoting'ono ta mchenga timakonzedwa ndi percolation cyanidation.

Kutsiliza

Kapangidwe ka golide wopangidwa ndi okosijeni kumadalira mtundu wa miyalayo komanso mawonekedwe a golide. Posankha njira zoyenera zopindulira ndi kukhathamiritsa, kugaya, ndi kupatukana, mitengo yobweza golide imatha kukulitsidwa ndikupindula bwino pachuma.

Shanxi United Chemical zimapanga apamwamba Sodium cyanide kudzera muukadaulo wapamwamba komanso zida. Pamafunso aumisiri okhudzana ndi golide wa cyanidation, mulu wa leaching, ndi zina zambiri, mutha kutifunsa nthawi iliyonse. Timathandiza makasitomala kupeza golide wabwino kwambiri komanso wokhazikika.
