Kuyanjana kwa Sodium Sulfide ndi Ma Reagents Ena mu Njira Yakuyandama

M'munda wa Mchere processing, kuyandama ndi njira yogwiritsidwa ntchito kwambiri yolekanitsa mchere wamtengo wapatali ku gangue. Sodium sulfide imagwira ntchito yofunika kwambiri pochita izi, makamaka yomwe imagwiritsidwa ntchito posintha pH ya zamkati, sulfidize, kukhumudwa, ndikuvula pamwamba pa mchere. Zogwirizana nazo Osonkhetsa, Abalendipo Olamulira ndizovuta komanso zimakhudza kwambiri magwiridwe antchito ndi kusankha kwa flotation.

Kuyanjana ndi Osonkhanitsa

Chikoka pa Sulfide Mineral Collectors

Kwa otolera ambiri a mchere wa sulfide monga xanthates ndi dithiophosphates, pamene mlingo wa Sodium sulfide Ndikoyenera, imatha kupititsa patsogolo hydrophobicity ya mchere wa sulfide, kupangitsa osonkhanitsa kuti azitha kutsatsa bwino pamtunda ndikuwongolera kuyandama kwa mchere. Komabe, sodium sulfide ikachuluka, imapanga filimu ya hydrophilic pamwamba pa mchere wa sulfide, kulepheretsa kutengeka kwa osonkhanitsa ndipo motero kuchita gawo loletsa. Mwachitsanzo, pakuyandama kwa miyala yamkuwa ya sulfure, kuchuluka koyenera kwa sodium sulfide kumatha kulimbikitsa kusonkhanitsa kwa chalcopyrite ndi xanthate, pomwe kuchuluka kwakukulu kumalepheretsa kuyandama kwa chalcopyrite.

Chikoka pa Oxide Mineral Collectors

Pakuyandama kwa mchere wa oxide, sodium sulfide imatha sulfidize pamwamba pa mchere wa oxide, kuwalola kuti asonkhanitsidwe ndi osonkhanitsa mchere wa sulfide. Mwachitsanzo, pamene ntchito mafuta asidi otolera kuti tiwolokere cerussite, sodium sulfide choyamba sulfidizes padziko cerussite ndiyeno interacts ndi mafuta asidi wokhometsa, kuwongolera flotation zotsatira za cerussite.

Kumanani ndi anthu Frothers

Sodium sulfide palokha alibe thovu katundu, koma zingakhudze katundu wa zamkati ndi pamwamba pa mchere, potero kusonkhezera thovu zotsatira za frothers. Kuchuluka koyenera kwa sodium sulfide kumapangitsa pamwamba pa hydrophobicity ya mchere kukhala yabwino, yomwe imathandizira kulumikizidwa kwa thovu ku mchere, kuwongolera mpweya wabwino komanso kukhazikika kwa thovu kwa frothers. Komabe, kuchuluka kwa sodium sulfide kumabalalitsa matope abwino mu zamkati, kuonjezera kukhuthala kwa zamkati, kupangitsa chithovu kukhala chomata, komanso kukhudza kukhazikika kwa thovu, zomwe sizingathandizire kupukuta kwa thovu loyandama komanso kulekanitsa kokhazikika.

Kuyanjana ndi Owongolera Ena

Synergistic Effect yokhala ndi pH Regulators

Sodium sulfide hydrolyzes kukhala zamchere ndipo akhoza synergistically kuchita ndi ena pH owongolera monga laimu ndi sodium carbonate kuti molumikizana kusintha pH mtengo wa zamkati. Mwachitsanzo, mu kuyandama kwa lead-zinc ore, sodium sulfide ndi laimu nthawi zambiri amagwiritsidwa ntchito limodzi kuti asunge zamchere zamchere, kuletsa mchere wodetsedwa monga pyrite, ndikuwongolera kusankha kwa flotation wa ore-zinc ore.

Kuyanjana ndi Depressants

Sodium sulfide imakhala ndi zoletsa zofananira ndi zokhumudwitsa zina monga cyanide ndi galasi lamadzi. Nthawi zina, amatha kugwiritsidwa ntchito limodzi kuti apititse patsogolo mphamvu yoletsa. Mwachitsanzo, mu kuyandama kwa mkuwa-kutsogolera-zinki polymetallic ore, ophatikizana ntchito sodium sulfide ndi cyanide angalimbikitse chopinga wa sphalerite ndi pyrite, kukwaniritsa ogwira kulekana kwa mkuwa-kutsogolera ku nthaka-sulfure. Komabe, chidwi chiyenera kuperekedwa pakuwongolera mlingo ndi ndondomeko yowonjezera; apo ayi, kulepheretsa kwakukulu kungachitike, zomwe zimakhudza kuchuluka kwa kuchira.

Kuyanjana ndi Activators

Sodium sulfide imakhala ndi mphamvu yotsegula pa mchere wina woletsedwa ndipo ingagwiritsidwe ntchito limodzi ndi ma activator. Mwachitsanzo, mu kulekanitsa flotation wa sulfide mkuwa-kutsogolera ore, galena inhibited cyanide akhoza adamulowetsa ndi sodium sulfide kenako anasonkhanitsa ndi ethyl thionocarbamate kukwaniritsa kulekana kwa mkuwa ndi kutsogolera. Panthawi imodzimodziyo, sodium sulfide ingakhudzenso zotsatira za zoyambitsa zina. Mwachitsanzo, kuchuluka kwa sodium sulfide kumatha kudya ayoni yogwira mu zamkati, kuchepetsa mphamvu ya activator.

Pomaliza, kumvetsetsa kuyanjana kwa sodium sulfide ndi ma reagents ena mumayendedwe oyandama ndikofunikira kwambiri pakuwongolera njira yoyandama, kuwongolera kuchira komanso kuchuluka kwa mchere wamtengo wapatali, komanso kuchepetsa mtengo wamafuta opangira mchere. Akatswiri opanga ma minerals amayenera kusintha mosamalitsa mlingo ndikuwonjezera kutsata kwa ma reagents osiyanasiyana molingana ndi momwe chitsulo chimapangidwira kuti akwaniritse zotsatira zabwino zoyandama.
