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

M'munda wa mineral processing, makamaka mu ndondomeko ya cyanidation kwa golidi ndi siliva m'zigawo, kusintha Sodium Cyanide Mlingo malinga ndi kukula kwa tinthu tating'ono ndikofunikira kwambiri pakuwongolera bwino leaching ufanisi ndi kuchepetsa ndalama zopangira. Nkhaniyi ikufuna kupereka chitsogozo chokwanira cha momwe mungasinthire izi.

Njira Yachikoka ya Ore Particle Kukula pa Cyanidation Reaction

Surface Area ndi Reaction Kinetics

Tinthu tating'onoting'ono tating'onoting'ono timakhala ndi malo okulirapo. Liti sodium cyanide njira amachitira ndi ore, lalikulu padziko m'dera amalola zambiri kukhudzana mfundo pakati pa cyanide ma ion ndi mchere womwe mukufuna (monga golide kapena siliva). Malinga ndi chiphunzitso cha kinetics, momwe zimachitikira zimayenderana ndi malo a reactants. Mwachitsanzo, mu kafukufuku wokhudza golide wa cyanidation, anapeza kuti pamene tinthu tating'onoting'ono tating'ono tating'ono tachepetsedwa kuchoka pa kukula kowawa mpaka -38 μm ndi chiŵerengero cha 75%, mlingo wa leaching wa golide unakula kwambiri. Ndi tinthu tating'onoting'ono tating'ono, maatomu ochulukirapo a golide padziko lapansi amawonetsedwa ndi ma cyanide ions, zomwe zimathandizira kuchita bwino.

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

Ambiri, mkati mwa osiyanasiyana, kuchuluka kwa Sodium cyanide anawonjezera ndi molingana ndi kumtunda kwa particles ore. Pamene tinthu tating'ono ting'onoting'ono timakhala bwino (malo okulirapo), sodium cyanide imafunikanso kuonetsetsa kuti ikugwirizana ndi mchere womwe umafuna. Komabe, ubalewu suli wa mzere mpaka kalekale. Kuchuluka kwa sodium cyanide kupitilira mulingo wina, kutulutsa bwino sikungachuluke kwambiri, ndipo kungayambitse 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

Asanayambe kupanga mafakitale akuluakulu, kuyezetsa ma labotale kuyenera kuchitidwa. Konzani zitsanzo za ore ndi kukula kosiyanasiyana kwa tinthu kudzera mukupera ndi sieving. Kenako, chititsani mayeso a cyanidation leaching pazitsanzozi ndi mitundu yosiyanasiyana ya sodium cyanide. Yezerani kuchuluka kwa mchere womwe mukufuna (monga golide kapena siliva) mosiyanasiyana. Mwa kusanthula deta yoyeserera, yambitsani ubale pakati pa kukula kwa tinthu tating'ono, mlingo wa sodium cyanide, ndi kutsika kwa magazi. Mwachitsanzo, kwa miyala ya golide yokhala ndi tinthu tating'onoting'ono ta -200 mesh (pafupifupi 74 μm), kuyezetsa kwa labotale kumatha kuwonetsa kuti mlingo wa sodium cyanide ukawonjezedwa kuchokera pa 1 kg/t mpaka 2 kg/t, kuchuluka kwa golide kumawonjezeka kuchoka pa 70% mpaka 85%, koma kukulitsa mlingo mpaka 3 kg/t kumangowonjezera 87%. Izi zitha kugwiritsidwa ntchito ngati zofotokozera zamakampani opanga 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.
