Udindo wa Copper sulfate mu Mineral Processing Industry

M'munda wovuta komanso wofunikira wa Mchere processing, ma reagents osiyanasiyana amankhwala amagwira ntchito yofunika kwambiri pakuwongolera kulekanitsa ndi kuchotsa mchere wamtengo wapatali. Copper sulfate, yokhala ndi mankhwala ake apadera, yatuluka ngati reagent yofunika kwambiri pamsika uno. Nkhaniyi ikufotokoza za ntchito zambiri za Mkuwa pokonza mchere, kufufuza njira zake ndi ntchito zake.

Kutsegula kwa Minerals

Imodzi mwamaudindo oyamba komanso odziwika bwino a mkuwa sulphate pakukonza mchere ndi ntchito yake ngati activator. Mu sulfide ore Flotation, mwachitsanzo, ili ndi chodabwitsa Kutsegula zotsatira za mchere wambiri monga sphalerite, stibnite, pyrite, ndi pyrrhotite, zomwe zimakhudza kwambiri sphalerite.

Njira Zoyambitsa

1.Metathesis Reaction Kuti Mupange Kanema Woyambitsa

Pamene copper sulphate imagwiritsidwa ntchito kuyambitsa sphalerite, metathesis reaction imachitika. Ma ion a mkuwa a divalent ndi ofanana ndi ayoni a zinc, ndipo kusungunuka kwa copper sulfide ndikocheperako kuposa zinc sulfide. Zotsatira zake, filimu yamkuwa ya sulfide imatha kupangidwa pamwamba pa sphalerite. Pambuyo popanga filimu yamkuwa ya sulfide, imatha kuyanjana nayo Osonkhetsa monga xanthates. Ma Xanthates ali ndi mgwirizano wamphamvu wamkuwa wa sulfide, womwe umapangitsa kuti hydrophobicity ya pamwamba pa sphalerite ikhale yosavuta, zomwe zimapangitsa kuti mcherewo ukhale wosavuta kuti ugwirizane ndi thovu la mpweya ndikuyandama, motero kuyambitsa sphalerite.

2.Kuchotsa Zoletsa ndi Kupanga Filimu Yoyambitsa

Nthawi zina, mchere ukhoza kuletsedwa ndi zinthu zina. Mwachitsanzo, pamene Sodium Cyanide imagwiritsidwa ntchito ngati choletsa pakuyandama, imatha kupanga zinc yokhazikika - cyanide Ma ions ovuta pamwamba pa sphalerite, omwe amalepheretsa kuyandama kwa sphalerite. Komabe, copper - cyanide complex ions ndi okhazikika kuposa zinc - cyanide complex ions. Pamene mkuwa sulphate anawonjezera sphalerite slurry choletsedwa cyanide, ndi cyanide ankafuna kusintha zinthu mopitirira pamwamba pa sphalerite kugwa, ndi ufulu mkuwa ayoni ndiye anachita ndi sphalerite kupanga kutsegula filimu yamkuwa sulfide, potero re - activating ndi sphalerite sphalerite.

Kuwongolera kwa Slurry pH

Copper sulphate imagwiranso ntchito ngati chowongolera mumchere wopangira mchere, makamaka pankhani ya kusintha kwa pH. Mtengo wa pH wa slurry ndi chinthu chofunikira kwambiri chomwe chimakhudza momwe zinthu zilili pamtunda wa mchere komanso magwiridwe antchito a flotation reagents.

Mkuwa wa sulphate ukawonjezedwa ku slurry, ukhoza kukumana ndi hydrolysis m'madzi. Zotsatira za sulfuric acid zimatha kuwonjezera kuchuluka kwa ayoni wa haidrojeni mu slurry, motero kutsitsa pH mtengo. Pa mtengo woyenerera wa pH, copper sulfate imatha kuchitapo kanthu ndi ayoni wa haidrojeni pamtunda wa mchere kupanga zinthu zomwe zimaphatikizana ndi mchere. Izi zitha kukulitsa hydrophilicity ndi kukwera kwa mchere, kulimbikitsa kuyandama. Mwachitsanzo, mu golide - okhala ndi ores, kusintha pH ya slurry ndi mkuwa sulphate kungapangitse kugwirizana pakati pa golide - kukhala ndi mchere ndi otolera, kupititsa patsogolo flotation kuchira golide.

Kuletsa Mchere Wosafunikira

Kuphatikiza pa kuyambitsa, copper sulfate imathanso kugwira ntchito ngati choletsa nthawi zina. Pakuyandama, nthawi zambiri pamafunika kulekanitsa mchere womwe ukufunidwa ndi mchere wina wosafunikira. Copper sulfate angagwiritsidwe ntchito kuletsa kuyandama kwa mchere womwe sunafike.

Mukawonjezeredwa ku slurry, mkuwa wa sulphate ukhoza kupanga anions omwe amakongoletsedwa pamwamba pa mchere wina umene sufuna kuyandama. Kutsatsa uku kumachepetsa hydrophilicity ndi kukwera kwa mchere womwe sali chandamale, kuwalepheretsa kuyandama pamodzi ndi mchere womwe mukufuna. Mwachitsanzo, mu dongosolo flotation kumene cholinga ndi kulekanitsa mchere golide ku mchere ena gangue, kuwonjezera mkuwa sulfate zoletsa kuti slurry akhoza kusunga gangue mchere pansi pa selo flotation pamene kulola golide mchere kuyandama pamwamba ndi thandizo la otolera ndi thovu.

Kusintha kwa Mineral Surfaces

Copper sulphate imatha kukhala ngati mineral surface modifier, kusintha zinthu zakuthupi ndi zakuthupi zamchere zamchere. Pakuyandama kwa golide, mphamvu zamagetsi ndi hydrophilicity ya mchere ndizinthu zazikulu zomwe zimakhudza kuyendetsa bwino ntchito.

Mu mineral slurry, mkuwa wa sulfate ukhoza kupanga mkuwa - wokhala ndi ayoni. Ma ion awa amatha kuchitapo kanthu ndi ayoni achitsulo pamwamba pa mcherewo, kusintha mawonekedwe ake amadzimadzi. Mwachitsanzo, pamwamba pa golide - kukhala ndi mchere wosanjikiza ena okusayidi wosanjikiza, mkuwa - munali ayoni akhoza kuchita ndi ayoni zitsulo mu oxide wosanjikiza, kupanga mankhwala atsopano padziko. Izi zitha kusintha kuchuluka kwa kuchuluka kwa mchere komanso kuchuluka kwa mankhwala.

Kuphatikiza apo, mkuwa wa sulphate ungakhudzenso hydrophilicity ya mchere. Powonjezera malo olumikizana pakati pa mchere ndi madzi, zitha kupititsa patsogolo kufalikira kwa mchere mu slurry. Kubalalitsidwa kowonjezerekaku kungakhale kopindulitsa pazotsatira za osonkhanitsa. Osonkhanitsa akawonjezeredwa, amatha kulumikizana bwino ndi malo osinthidwa amchere, kulimbikitsa kulumikizidwa kwa mchere ku thovu la mpweya ndipo pamapeto pake kuwongolera kuyandama kwa migodi ya golide.

Kutsiliza

Mwachidule, copper sulfate imagwira ntchito zosiyanasiyana komanso zofunikira pamakampani opanga mchere. Monga activator, imatha kupititsa patsogolo magwiridwe antchito a mchere monga sphalerite popanga mafilimu oyambitsa kapena kuchotsa zoletsa. Monga chowongolera, imathandizira kukhathamiritsa pH ya slurry, yomwe ndiyofunikira kuti ntchito yoyandama igwire bwino. Monga inhibitor, imatha kuteteza kuyandama kwa mchere wosafunikira, ndikuwongolera chiyero cha kukhazikika komaliza. Ndipo monga mineral surface modifier, imatha kusintha mankhwala ndi mawonekedwe a mchere, kupititsa patsogolo mgwirizano pakati pa mchere ndi ma reagents oyandama. Kugwiritsa ntchito bwino kwa copper sulfate pakukonza mchere sikumangowonjezera mphamvu ya kulekanitsa mchere komanso kumathandizira kuti chuma chikhale chokhazikika komanso chachuma.
