Kuyanjana kwa Sodium Sulfide ndi Ma Reagents Ena mu Njira Yakuyandama

Mu gawo la kukonza mchere , kuyandama ndi njira yomwe imagwiritsidwa ntchito kwambiri polekanitsa mchere wamtengo wapatali ndi gangue. Sodium sulfide imagwira ntchito yofunika kwambiri pankhaniyi, makamaka imagwiritsidwa ntchito kusintha pH ya zamkati, sulfidize, kufinya, ndikuchotsa pamwamba pa mchere. Kuyanjana kwake ndi Collectors , Frothers , ndi Regulators ndi kovuta ndipo kumakhudza kwambiri magwiridwe antchito ndi kusankha kwa kuyandama.

Kuyanjana ndi Osonkhanitsa

Chikoka pa Sulfide Mineral Collectors

Kwa osonkhanitsa omwe amagwiritsidwa ntchito kwambiri pa mchere wa sulfide monga xanthates ndi dithiophosphates, ngati mlingo wa Sodium sulfide uli woyenera, ukhoza kuwonjezera kusagwirizana kwa pamwamba pa mchere wa sulfide, zomwe zimathandiza osonkhanitsa kuti azimwa bwino pamwamba pa mchere ndikukweza kuyandama kwa mchere. Komabe, pamene sodium sulfide yachuluka, imapanga filimu yofanana ndi hydrophilic pamwamba pa mchere wa sulfide, zomwe zimalepheretsa kuyandama kwa osonkhanitsa motero zimakhala zoletsa. Mwachitsanzo, pakuyandama kwa mkuwa-sulfur ore, kuchuluka koyenera kwa sodium sulfide kungathandize kusonkhanitsa chalcopyrite ndi xanthate, pomwe kuchuluka kwambiri kumaletsa 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 imasungunuka kukhala alkaline ndipo imatha kugwira ntchito limodzi ndi ena owongolera pH monga lime ndi sodium Carbon ate kuti isinthe pH ya zamkati. Mwachitsanzo, pakuyandama kwa lead-zinc ore, sodium sulfide ndi laimu nthawi zambiri zimagwiritsidwa ntchito pamodzi kuti zisunge alkaline ya zamkati, kuletsa mchere wodetsedwa monga pyrite, ndikuwonjezera kusankha kwa flotation kwa lead-zinc ore.

Kuyanjana ndi Depressants

Sodium sulfide ili ndi zotsatira zofanana zoletsa zinthu zina monga cyanide ndi galasi lamadzi. Nthawi zina, zingagwiritsidwe ntchito pamodzi kuti ziwonjezere mphamvu yoletsa. Mwachitsanzo, pakuyandama kwa mkuwa-lead-zinc polymetallic ore, kugwiritsa ntchito pamodzi kwa sodium sulfide ndi cyanide kungalimbikitse kuletsa kwa sphalerite ndi pyrite, zomwe zimapangitsa kuti mkuwa-lead ukhale wosiyana ndi zinc-sulfur. Komabe, chisamaliro chiyenera kuperekedwa pakuwongolera mlingo ndi kutsatizana kwa kuwonjezera; apo ayi, kuletsa kwambiri kungachitike, zomwe zingakhudze 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.
