Umgomo wokuvinjwa kanye nokusetshenziswa kwe-zinc sulfate inhibitors

Ukuze uthuthukise ukukhetha kwenqubo ye-flotation, thuthukisa imiphumela yabaqoqi kanye nama-foaming agents, wehlise ukufakwa okuningana kwamaminerali asebenzayo, futhi uthuthukise izimo ezithambile ze-flotation, abalawuli bavame ukusetshenziswa kwinqubo ye-flotation. Ukulungiswa kwenqubo ye-flotation kufaka amakhemikhali amaningi. Ngokweqhaza labo kwinqubo ye-flotation, bangahlukaniswa ngama-inhibitors, ama-activators, ama-medium amoncher, ama-ejenti ancishisiwe, ama-flocculants, ama-dispersants, njll.

Ngesikhathi senqubo ye-froth flotation, ama-inhibitors ama-ejenti angavimba noma anciphise i-adsorption noma isenzo somqoqi ngaphezulu kwamaminerali angewona ama-flotation, futhi akha ifilimu le-hydrophilic ebusweni bamaminerali.

I-Zinc Sulfate ingenye ye-inhibitors ebalulekile kwinqubo ye-froth flotation.

Isimiso sokuvinjwa kwe-zinc sulfate inhibitor
Ekukhiqizeni amaminerali ecubungula, i-zinc sulfate, i-cyside ye-lime, i-sodium sulfide, njll. Isetshenziswa kakhulu inhibitors.Zin sulfate iyinhlangano enhle ye-zinc blendehibitor enhle lapho isetshenziswa ngokuhlanganiswa namanye ama-ejenti.

Uyini umgomo wokuvinjwa we-zinc sulfate?

Imvamisa, umphumela wokuvinjwa okuvinjelwe kuphela kusebenza epulpini ye-alkaline. Okuphezulu kwe-PH, okusobala okusobala okuvinjelwe. Emanzini, i-zinc sulfate isabela kanjena:

Znso4 = zn (2 +) + so4 (2-)

I-ZN (2 +) + 2H2O = ZN (oh) 2 + 2h (+) [Zn (oh) [Zn (oh)

Zn (oh) 2 + H22SO4 = ZNSO4 + 2H2O

E-Alkaline Media, Hzno2 (-) kanye ne-ZNO2 (2-) kukhiqizwa, okuyi-adsorbed kumaminerali futhi athuthukise i-hydrophility yendawo yamaminerali.

Zn (oh) 2 + Naoh = nahzno2 + h2o

I-ZN (OH2 + 2Anaoh = NA2ZNO2 + 2h2O

Ekusebenzeni kwamaminerali, i-zinc sulfate ngokuvamile ayisetshenziswa yodwa njenge-inhibitor, kepha ivame ukusetshenziswa ngokuhlanganiswa ne-cyanide, i-sodium sulfide, i-sodium carbonate, i-cyanide: i-zinc sulfate = 1: 2 ~ 5. Ukusetshenziswa okuhlangene kwe-sulfuric acid kanye ne-cyanide kungathuthukisa umphumela wokuvinjwa ku-sphalerite.

Ukusetshenziswa kwe-Zinc Sulfate inhibitors
I-Zinc Sulfate ingusawoti onamandla we-alkali nosawoti we-alkali obuthakathaka, imvamisa ngamanzi ayi-7 ama-crystal (zns · 7hh2o), umkhiqizo omsulwa (anhydrous), i-crystal emhlophe, ukuncibilika kalula emanzini. Okuqukethwe kwe-Zinc Sulfate kwikhambi laso eligcwele kungu-29.4%, bese kuthi ikhambi elinamanzi ane-acidic. . Ekukhiqizeni, kuvame ukusetshenziswa njengesisombululo esingamanzi angama-5%.

Lapho i-zinc sulfate ixubene ne-lime, iyi-inhibitor esebenzayo ye-zinc sulfide minerals (i-zinc blende noma i-iron blende). Inani eliphakeme le-PH ye-Slurry, elinamandla okuvinjelwa kwe-zinc sulfate kumaminerali eZins Sulfide Minerals.

Ngokuvamile kuzwakala ukuthi umphumela wokuvinjwa kwe-zinc sulfate kumaminerali we-zinc sulfide kungenxa ye-adsorption ye-zn (oh) 2, i-Hzno2 (-), noma i-zno2 (2-), noma i-zno2 (2-), noma i-ZNO2 Media to yakha ifilimu le-hydrophilic. Okubangelwa.

I-Zinc Sulfate kwesinye isikhathi ixubene ne-cyanide ne-lime. Ukuhleleka kokuvinjwa kwazo kwamamishini wensimbi sulfide amaminerali yile: Spholite> I-Pyrite> Marcasite> Imayini yaseChalcocite. Ngakho-ke, lapho uhlukanisa amaminerali e-polymetallic sulfide, umthamo wama-inhibitors kumele alawulwe ngokuqinile.
