Copper sulfate, e hlahang e le likristale tse putsoa kapa tse botala bo boputsoa, ke activator e sebelisoang haholo ho phaphamala ha ore ea sulfide.Haholo-holo e sebelisoa e le activator, regulator le inhibitor ho lokisa boleng ba pH ba slurry, ho laola ho hlahisa foam le ho ntlafatsa Bokhoni ba holim'a liminerale bo na le phello ea ts'ebetso ho sphalerite, stibnite, pyrite le pyrrhotite, haholo-holo sphalerite e thibeloang ke lime. kapa cyanide.
Karolo ea koporo ea sulfate ho flotation ea liminerale:
1. E sebelisoa e le activator
E ka fetola thepa ea motlakase ea bokaholimo ba liminerale mme ea etsa hore bokaholimo ba liminerale bo be hydrophilic.Hydrophilicity ena e ka eketsa sebaka sa ho kopana pakeng tsa liminerale le metsi, e leng ho nolofalletsang hore mineral e phaphametse.Copper sulfate e ka boela ea theha cations ka har'a slurry ea liminerale, tse ntseng li tsoela pele ho khabisoa holim'a merafo, ho eketsa hydrophilicity le buoyancy.
The activation mechanism e kenyelletsa lintlha tse peli tse latelang:
①.Karabelo ea metathesis e etsahala ka holim'a minerale e kentsoeng ho etsa filimi ea ts'ebetso.Ka mohlala, sulfate ea koporo e sebelisetsoa ho kenya sphalerite.Sebaka sa li-ion tsa koporo tsa divalent se tšoana le radius ea zinki, 'me ho qhibiliha ha sulfide ea koporo ho nyane haholo ho feta zinc sulfide.Ka hona, filimi ea koporo ea sulfide e ka thehoa holim'a sphalerite.Ka mor'a hore filimi ea koporo ea sulfide e thehoe, e ka sebelisana habonolo le moqoqo oa xanthate, e le hore sphalerite e sebetse.
②.Tlosa inhibitor pele, ebe u theha filimi ea ts'ebetso.Ha sodium cyanide e thibela sphalerite, li-ion tse tsitsitseng tsa zinc cyanide li thehoa holim'a sphalerite, 'me li-ion tsa koporo tsa cyanide li tsitsitse ho feta li-ion tsa zinc cyanide.Haeba sulfate ea koporo e eketsoa ho sphalerite slurry e thibetsoeng ke cyanide, li-radicals tsa cyanide tse holim'a sphalerite li tla oa, 'me li-ion tsa mahala tsa koporo li tla itšoara ka sphalerite ho etsa filimi ea ts'ebetso ea koporo ea sulfide, ka tsela eo e kenya letsoho. sphalerite.
2. E sebelisoa e le molaoli
Boleng ba pH ba slurry bo ka fetoloa.Ka boleng bo nepahetseng ba pH, sulfate ea koporo e ka sebetsana le li-ion tsa haedrojene holim'a liminerale ho etsa lintho tsa lik'hemik'hale tse kopanang le bokaholimo ba liminerale, e leng ho eketsang hydrophilicity le buoyancy ea liminerale, ka ho etsa joalo e khothaletse phello ea ho phaphamala ha merafo ea khauta.
3. E sebelisoa e le inhibitor
Li-Anion li ka thehoa ka har'a slurry le adsorbed ka holim'a liminerale tse ling tse sa hlokeng ho phaphamala, ho fokotsa hydrophilicity le buoyancy, kahoo ho thibela liminerale tsena ho phaphamala hammoho le liminerale tsa khauta.Hangata li-inhibitors tsa koporo tsa sulfate li kenyelletsoa ho slurry ho boloka liminerale tse sa hlokeng ho phaphamala ka tlaase.
4. E sebelisoa e le mofetoleli oa holim'a liminerale
Fetola likarolo tsa lik'hemik'hale le tsa 'mele tsa bokaholimo ba liminerale.Ho phaphamala ha ore ea khauta, thepa ea motlakase le hydrophilicity ea bokaholimo ba liminerale ke lintlha tsa bohlokoa tsa ho phaphamala.Copper sulfate e ka etsa li-ion tsa koporo ea oxide ka har'a mineral slurry, e sebetsana le li-ion tsa tšepe holim'a merafo, ebe e fetola likarolo tsa eona tsa lik'hemik'hale.Copper sulfate e ka boela ea fetola hydrophilicity ea libaka tsa liminerale le ho eketsa sebaka sa ho kopana pakeng tsa liminerale le metsi, kahoo e khothalletsa phello ea flotation ea merafo ea khauta.
