Kusanthula mwachidule za ntchito ya mkuwa sulfate mu ore beneficiation ndi flotation

Copper sulfate, yomwe imawoneka ngati makhiristo a buluu kapena buluu wobiriwira, ndi activator yomwe imagwiritsidwa ntchito kwambiri pakuyandama kwa miyala ya sulfide.Amagwiritsidwa ntchito makamaka ngati activator, regulator ndi inhibitor kuti asinthe pH mtengo wa slurry, kuwongolera kutulutsa chithovu ndikuwongolera Kuthekera kwa mchere kumapangitsa kuti pakhale sphalerite, stibnite, pyrite ndi pyrrhotite, makamaka sphalerite yomwe imaletsedwa ndi laimu. kapena cyanide.

Udindo wa copper sulfate mu mineral flotation:

1. Ntchito ngati activator

Ikhoza kusintha mphamvu zamagetsi za malo amchere ndikupanga mchere kukhala hydrophilic.Hydrophilicity iyi imatha kukulitsa malo olumikizana pakati pa mchere ndi madzi, zomwe zimapangitsa kuti mcherewo uyandame mosavuta.Copper sulphate akhoza kupanga cations mu mchere slurry, amenenso adsorbed padziko mchere, kuwonjezera hydrophilicity ake ndi buoyancy.

The activation mechanism ili ndi mbali ziwiri izi:

①.Metathesis reaction imachitika pamwamba pa mineral activated kuti apange activation filimu.Mwachitsanzo, copper sulphate imagwiritsidwa ntchito kuyambitsa sphalerite.Utali wozungulira wa ayoni amkuwa wa divalent ndi wofanana ndi utali wa ayoni a zinki, ndipo kusungunuka kwa mkuwa sulfide ndikocheperako kuposa zinc sulfide.Choncho, filimu yamkuwa ya sulfide imatha kupangidwa pamwamba pa sphalerite.Pambuyo popanga filimu yamkuwa ya sulfide, imatha kuyanjana mosavuta ndi xanthate wosonkhanitsa, kotero kuti sphalerite imatsegulidwa.

②.Chotsani choletsa choyamba, kenako pangani filimu yoyambitsa.Pamene sodium cyanide imalepheretsa sphalerite, ayoni okhazikika a zinc cyanide amapangidwa pamwamba pa sphalerite, ndipo ayoni amkuwa a cyanide amakhala okhazikika kuposa ayoni a zinc cyanide.Ngati mkuwa wa sulphate wawonjezeredwa ku sphalerite slurry yomwe imaletsedwa ndi cyanide, ma radicals a cyanide pamwamba pa sphalerite adzagwa, ndipo ma ion amkuwa aulere adzachitapo kanthu ndi sphalerite kupanga filimu yotsegulira yamkuwa sulfide, potero kuyambitsa sphalerite.

2. Amagwiritsidwa ntchito ngati wowongolera

Mtengo wa pH wa slurry ukhoza kusinthidwa.Pa mtengo woyenerera wa pH, copper sulfate imatha kuchitapo kanthu ndi ayoni wa haidrojeni pamtunda wa mchere kupanga zinthu zomwe zimaphatikizana ndi mchere, kukulitsa hydrophilicity ndi kusungunuka kwa mchere, potero kulimbikitsa kuyandama kwa migodi ya golide.

3. Amagwiritsidwa ntchito ngati choletsa

Anyezi akhoza kupangidwa mu slurry ndi adsorbed pamwamba pa mchere zina zimene safuna kuyandama, kuchepetsa hydrophilicity awo ndi buoyancy, motero kupewa mchere izi kuti ayandama pamodzi ndi golide mchere.Copper sulfate inhibitors nthawi zambiri amawonjezeredwa ku slurry kuti asunge mchere womwe sufuna kuyandama pansi.

4. Amagwiritsidwa ntchito ngati mineral surface modifier

Kusintha mankhwala ndi thupi katundu wa mchere pamwamba.Pakuyandama kwa golide, mphamvu zamagetsi ndi hydrophilicity ya mchere ndi zinthu zazikulu zoyandama.Copper sulphate imatha kupanga ayoni amkuwa a oxide mu mchere wothira, kuchitapo kanthu ndi ayoni achitsulo pamwamba pa mchere, ndikusintha mawonekedwe ake amadzimadzi.Copper sulfate imathanso kusintha hydrophilicity ya malo amchere ndikuwonjezera malo olumikizana pakati pa mchere ndi madzi, motero kulimbikitsa kuyandama kwa migodi ya golide.
