Momwe Mungasinthire Mlingo wa Sodium Cyanide Molingana ndi Kukula kwa Ore Particle?

Pankhani yokonza mchere, makamaka pa njira yopangira cyanidation kuti muchotse golide ndi siliva, kusintha mlingo wa Sodium Cyanide malinga ndi kukula kwa tinthu ta mkuwa ndikofunikira kwambiri pakukonza bwino ntchito yochotsa mchere ndikuchepetsa ndalama zopangira. Nkhaniyi ikufuna kupereka chitsogozo chokwanira cha momwe mungapangire kusinthaku.

Njira Yachikoka ya Ore Particle Kukula pa Cyanidation Reaction

Surface Area ndi Reaction Kinetics

Tinthu tating'onoting'ono ta mkuwa timakhala ndi malo akuluakulu pamwamba pake. Pamene yankho la sodium cyanide likugwirizana ndi mkuwa, malo akuluakulu pamwamba pake amalola malo ambiri olumikizirana pakati pa ma ayoni a cyanide ndi mchere womwe umagwiritsidwa ntchito (monga golide kapena siliva). Malinga ndi chiphunzitso cha reaction kinetics, liwiro la reaction limagwirizana ndi malo apamwamba a ma reactants. Mwachitsanzo, mu kafukufuku wokhudza golide cyanidation, zidapezeka kuti pamene kukula kwa tinthu ta mkuwa kunachepetsedwa kuchoka pa kukula kwakukulu kufika pa -38 μm ndi chiŵerengero cha zomwe zili mu 75%, liwiro la leaching la golide linawonjezeka kwambiri. Ndi tinthu tating'onoting'ono, maatomu ambiri agolide pamwamba pake amakumana ndi ma ayoni a cyanide, zomwe zimathandiza kuti pakhale reaction yogwira mtima kwambiri.

Komano, tinthu tating'onoting'ono timakhala ndi malo ang'onoang'ono kuti achitepo kanthu. Ma cyanide ions amatha kuchitapo kanthu ndi gawo lakunja la tinthu tating'onoting'ono, ndipo kufalikira kwa ayoni a cyanide mkati mwa tinthu tating'onoting'ono kumachedwa. Izi kumabweretsa m'munsi wonse anachita mlingo ndi chosakwanira leaching chandamale mchere mkati particles.

Diffusion Chotchinga

Pankhani ya miyala yamtengo wapatali, mtunda umene ma ayoni a cyanide amafunikira kuti afalikire kuti akafike ku mchere womwe ukufunidwa ndi waufupi. Izi zimachepetsa kukana kwa diffusion ndikupangitsa kuti zichitike mwachangu. Pamene kukula kwa tinthu tating'onoting'ono kumawonjezeka, njira yophatikizika ya ayoni ya cyanide kudzera mumtundu wa porous wa tinthu tating'onoting'ono timatalika. Kukhalapo kwa mchere wa gangue mu tinthu tating'onoting'ono kumatha kukhalanso ngati chotchinga chosokoneza. Mwachitsanzo, ngati pali zigawo za minerals zosagwira ntchito za gangue zozungulira golide - zokhala ndi mchere mu tinthu tambirimbiri, zimatenga nthawi yayitali kuti ma cyanide ion alowe ndikuchitapo kanthu ndi golide, zomwe zimapangitsa kuti kutsika kwamadzi kuchepe.

Kuyeza kwa Ore Particle Kukula

Sieving Analysis

Sieving ndi njira yodziwika komanso yosavuta yodziwira kukula kwa tinthu tating'ono. Sefa wamba wokhala ndi ma mesh makulidwe osiyanasiyana amagwiritsidwa ntchito. Chitsanzo cha ore chimayikidwa pamwamba pa sieve ya stack, ndiyeno muluwo umagwedezeka mwamakina kwa nthawi inayake. Tinthu tating'onoting'ono tomwe timadutsa pasefa iliyonse timasonkhanitsidwa ndikuyesedwa. Powerengera kuchuluka kwa tinthu ting'onoting'ono tomwe timasungidwa pa sieve iliyonse, kugawa kwa tinthu tating'onoting'ono tachitsulo kumatha kupezeka. Mwachitsanzo, m’fakitale yokonza miyala ya golide, ngati chitsulocho chimasefa kudzera mu sieve zingapo zokhala ndi mauna 200. 325. ndi 400. peresenti ya tinthu tating’ono kwambiri kuposa kukula kwa mauna angadziŵike, zomwe zimathandiza kumvetsa ubwino wa zitsulo.

Laser Diffraction Particle Size Analysis

Iyi ndi njira yapamwamba komanso yolondola. Laser diffraction analyzers amagwira ntchito potengera mfundo yakuti mtengo wa laser ukadutsa m'malo omwazika tinthu, tinthu tating'onoting'ono timamwaza kuwala kwa laser. Ngodya ndi mphamvu ya kuwala kobalalika zimagwirizana ndi kukula kwa tinthu. Ndi kuyeza kuwala anamwazikana, chida akhoza kuwerengera tinthu kukula kugawa chitsanzo ore. Ikhoza kupereka mwatsatanetsatane za kukula kwa tinthu tating'onoting'ono, kuphatikizapo tinthu tating'onoting'ono tomwe tingakhale tating'ono ting'onoting'ono kuti tiyese molondola ndi sieving. Njirayi ndiyothandiza makamaka pochita ndi ores okhala ndi kukula kwa tinthu tating'onoting'ono kapena ngati miyeso yolondola kwambiri ikufunika kuti muwongolere njira ya cyanidation.

Mfundo ndi Njira Zosinthira Mlingo wa Sodium Cyanide

Mfundo Zazikulu

Ubale Wolingana M'magulu Ena

Kawirikawiri, mkati mwa mlingo winawake, kuchuluka kwa Sodium cyanide komwe kumawonjezeredwa kumagwirizana ndi malo a pamwamba pa tinthu ta mkuwa. Pamene kukula kwa tinthu ta mkuwa kumakhala kocheperako (malo akuluakulu), sodium cyanide yambiri imafunika kuti zitsimikizire kuti zinthuzo zikugwirizana ndi mchere womwe ukufunidwa. Komabe, ubalewu suli wolunjika kwamuyaya. Pamene kuchuluka kwa sodium cyanide kupitirira mlingo winawake, mphamvu yotulutsa madzi siingakwere kwambiri, ndipo izi zingayambitse kuwononga mankhwala ndikuwonjezera ndalama zopangira.

Kuganizira za Ore Makhalidwe

Mitundu yosiyanasiyana ya ore imakhala ndi mitundu yosiyanasiyana yamankhwala komanso kapangidwe kake. Ores ena amatha kukhala ndi mchere womwe umadya ayoni a cyanide, monga mchere wina wa sulfide. Zikatero, ngakhale kukula kwa tinthu tating'ono, sodium cyanide yambiri ingafunike kuti tikwaniritse zomwe mukufuna. Mwachitsanzo, ngati ore ali ndi gawo lalikulu la pyrite, pyrite ikhoza kuchitapo kanthu ndi ayoni a cyanide ndi mpweya mu yankho, kuwononga cyanide. Chifukwa chake, mulingo wa cyanide uyenera kusinthidwa molingana ndi kapangidwe kake ka mchere wa ore.

Njira Zosinthira

Kuyesa Kwasayansi

Musanayambe kupanga mafakitale akuluakulu, mayeso a labotale ayenera kuchitika. Konzani zitsanzo za miyala yokhala ndi tinthu tating'onoting'ono tosiyanasiyana kudzera mu kupukutira ndi kutsekereza. Kenako, chitani mayeso a cyanidation leaching pa zitsanzozi ndi mlingo wosiyana wa sodium cyanide. Yesani kuchuluka kwa leaching ya mchere womwe mukufuna (monga golide kapena siliva) pansi pa mikhalidwe yosiyanasiyana. Mwa kusanthula deta yoyesera, pangani ubale pakati pa kukula kwa tinthu tating'onoting'ono ta miyala, mlingo wa sodium cyanide , ndi kuchuluka kwa leaching. Mwachitsanzo, pa golide wokhala ndi tinthu tating'onoting'ono ta -200 mesh (pafupifupi 74 μm), mayeso a labotale angasonyeze kuti pamene mlingo wa sodium cyanide wawonjezeka kuchoka pa 1 kg/t mpaka 2 kg/t, kuchuluka kwa leaching ya golide kumawonjezeka kuchoka pa 70% mpaka 85%, koma kuwonjezera mlingo kufika pa 3 kg/t kumawonjezera kuchuluka kwa leaching kufika pa 87%. Deta iyi ingagwiritsidwe ntchito ngati chisonyezero cha kupanga mafakitale.

Kuyang'anira ndi Kusintha Kwapaintaneti mu Kupanga Kwa mafakitale

Mu kupanga mafakitale, Intaneti tinthu kukula analyzers akhoza kuikidwa kuti mosalekeza kuwunika tinthu kukula kwa ore kulowa cyanidation ndondomeko. Kutengera ubale womwe udakhazikitsidwa kale pakati pa kukula kwa tinthu ndi sodium cyanide mlingo kuchokera ku mayeso a labotale, makina odziyimira pawokha amatha kusinthidwa munthawi yeniyeni. Mwachitsanzo, ngati pa intaneti tinthu kukula analyzer detects kuti pafupifupi tinthu kukula kwa ore wakhala bwino, ndi basi dosing dongosolo akhoza kuonjezera sodium cyanide mlingo moyenerera kukhalabe mulingo woyenera kwambiri leaching dzuwa.

Pomaliza, kusintha mlingo wa sodium cyanide molingana ndi kukula kwa tinthu tating'ono ndi ntchito yovuta koma yofunika kwambiri pakupanga cyanidation. Pomvetsetsa momwe zimakhudzira kukula kwa tinthu tating'onoting'ono, kuyeza kukula kwa tinthu tating'onoting'ono, ndikutsata mfundo ndi njira zoyenera zosinthira, makampani opanga mchere amatha kupititsa patsogolo luso la cyanidation leaching, kuchepetsa kugwiritsa ntchito mankhwala, ndikuwonjezera phindu lonse lazachuma ndi chilengedwe.
