Udindo wa Copper sulfate mu Mineral Processing Industry

Mu gawo lovuta komanso lofunikira la kukonza mchere , ma reagents osiyanasiyana a mankhwala amachita gawo lofunikira kwambiri pakukonza ndi kugawa mchere wamtengo wapatali. Copper sulfate, yokhala ndi mawonekedwe ake apadera a mankhwala, yakhala ngati reagent yofunika kwambiri mumakampani awa. Nkhaniyi ikufotokoza za ntchito zambiri za Copper sulfate pakukonza mchere, pofufuza njira zake ndi momwe amagwiritsidwira ntchito.

Kutsegula kwa Minerals

Limodzi mwa ntchito zazikulu komanso zodziwika bwino za copper sulfate pakukonza mchere ndi ntchito yake ngati activator. Mwachitsanzo, mu sulfide ore Flotation , imakhala ndi mphamvu yodabwitsa yoyambitsa zinthu pa mchere wambiri monga sphalerite, stibnite, pyrite, ndi pyrrhotite, zomwe zimakhudza kwambiri sphalerite.

Njira Zoyambitsa

1.Metathesis Reaction Kuti Mupange Kanema Woyambitsa

Pamene copper sulfate ikugwiritsidwa ntchito kuyambitsa sphalerite, metathesis reaction imachitika. Utali wa ma divalent copper ions ndi wofanana ndi wa zinc ions, ndipo kusungunuka kwa copper sulfide ndi kochepa kwambiri kuposa kwa zinc sulfide. Zotsatira zake, wosanjikiza wa copper sulfide film ukhoza kupangidwa pamwamba pa sphalerite. Pambuyo poti copper sulfide film yapangidwa, imatha kuyanjana mosavuta ndi Osonkhanitsa monga xanthates. Xanthates ali ndi mphamvu yamphamvu ya copper sulfide, zomwe zimapangitsa kuti pamwamba pa sphalerite pakhale hydrophobicity, zomwe zimapangitsa kuti mcherewo ukhale wosavuta kulumikiza ku thovu la mpweya ndikuyandama, motero kuyambitsa sphalerite.

2.Kuchotsa Zoletsa ndi Kupanga Filimu Yoyambitsa

Nthawi zina, mchere ukhoza kulepheretsedwa ndi zinthu zina. Mwachitsanzo, pamene Sodium Cyanide ikugwiritsidwa ntchito ngati choletsa pakuyandama kwa nthaka, imatha kupanga ma ayoni okhazikika a zinc - cyanide complex pamwamba pa sphalerite, zomwe zimaletsa kuyandama kwa sphalerite. Komabe, ma ayoni ophatikizana a copper - cyanide ndi okhazikika kuposa ma ayoni ophatikizana a zinc - cyanide. Copper sulfate ikawonjezedwa ku slurry ya sphalerite yomwe imalepheretsedwa ndi cyanide, ma cyanide radicals pamwamba pa sphalerite amagwa, ndipo ma ayoni a copper aulere amachitapo kanthu ndi sphalerite kuti apange filimu yoyambitsa ya copper sulfide, potero amayatsanso sphalerite kuti iyandama.

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.
