Ukuhlaziywa kafushane kwendima ye-copper sulfate ekuzuzeni i-ore kanye nokuntanta

I-Copper sulfate, ebonakala njengamakristalu aluhlaza okwesibhakabhaka noma okuluhlaza okwesibhakabhaka, iyi-activator esetshenziswa kakhulu ekuntanteni kwe-sulfide ore.Isetshenziswa kakhulu njenge-activator, isilawuli kanye ne-inhibitor ukulungisa inani le-pH le-slurry, ukulawula ukukhiqizwa kwegwebu futhi kuthuthukiswe Amandla angaphezulu amaminerali anomphumela wokuvula ku-sphalerite, i-stibnite, i-pyrite ne-pyrrhotite, ikakhulukazi i-sphalerite evinjelwa umcako. noma i-cyanide.

Indima ye-copper sulfate ku-mineral flotation:

1. Isetshenziswa njenge-activator

Ingashintsha izici zikagesi zezindawo zamaminerali futhi yenze izindawo zamaminerali zibe ne-hydrophilic.Le hydrophilicity ingakhuphula indawo yokuxhumana phakathi kwamaminerali namanzi, okwenza kube lula ukuthi amaminerali antante.I-Copper sulfate nayo ingakha ama-cations ku-mineral slurry, aphinde adsorbed phezu kwe-mineral, okwandisa i-hydrophilicity yayo kanye ne-buoyancy.

Indlela yokwenza kusebenze ihlanganisa izici ezimbili ezilandelayo:

①.Ukusabela kwe-metathesis kwenzeka phezu kweminerali eyenziwe yasebenza ukuze yakhe ifilimu yokwenza kusebenze.Isibonelo, i-copper sulfate isetshenziselwa ukwenza kusebenze i-sphalerite.Irediyasi yama-ion ethusi e-divalent ifana ne-radius ye-zinc ion, futhi ukuncibilika kwe-copper sulfide kuncane kakhulu kunaleyo ye-zinc sulfide.Ngakho-ke, ifilimu ye-sulfide yethusi ingakhiwa ebusweni be-sphalerite.Ngemuva kokuthi ifilimu ye-sulfide yethusi yenziwe, ingakwazi ukuxhumana kalula nomqoqi we-xanthate, ukuze i-sphalerite isebenze.

②.Susa inhibitor kuqala, bese wenza ifilimu yokwenza kusebenze.Lapho i-sodium cyanide ivimbela i-sphalerite, i-zinc cyanide ions ezinzile yenziwa ebusweni be-sphalerite, futhi i-copper cyanide ions izinzile kune-zinc cyanide ions.Uma i-copper sulfate yengezwa ku-sphalerite slurry evinjelwa i-cyanide, ama-radicals e-cyanide ebusweni be-sphalerite azowa, futhi ama-ion e-copper amahhala azosabela nge-sphalerite ukuze enze ifilimu yokuqalisa ye-copper sulfide, ngaleyo ndlela isebenze. i-sphalerite.

2. Isetshenziswa njengomlawuli

Inani le-pH le-slurry lingashintshwa.Ngenani elifanele le-pH, i-copper sulfate ingakwazi ukusebenzisana nama-ion e-hydrogen endaweni yamaminerali ukuze kwakhe izinto zamakhemikhali ezihlangana ne-mineral surface, ikhulise i-hydrophilicity kanye nokushelela kweminerali, ngaleyo ndlela ikhuthaze umphumela wokuntanta kwezimayini zegolide.

3. Isetshenziswa njenge-inhibitor

Ama-anion angakhiwa odaka futhi akhangiswe phezu kwamanye amaminerali angadingi ukuntanta, okunciphisa i-hydrophilicity kanye nokuqina kwawo, ngaleyo ndlela kuvimbele la maminerali ukuthi angantanti kanye namaminerali egolide.I-Copper sulfate inhibitors ivame ukungezwa ku-slurry ukugcina amaminerali angadingi ukuntanta phansi.

4. Isetshenziswa njengesilungisi sendawo yamaminerali

Shintsha izakhiwo zamakhemikhali nezomzimba zezindawo zamaminerali.Ekuntanteni kwensimbi yegolide, izakhiwo zikagesi kanye ne-hydrophilicity yendawo yamaminerali yizici ezibalulekile zokuntanta.I-Copper sulfate ingenza ama-ion e-copper oxide ku-slurry yamaminerali, ihlangane nama-ion ensimbi ebusweni be-mineral, futhi iguqule izici zayo zamakhemikhali ezingaphezulu.I-Copper sulfate ingaphinde iguqule i-hydrophilicity yezindawo zamaminerali futhi ikhulise indawo yokuxhumana phakathi kwamaminerali namanzi, ngaleyo ndlela ikhuthaze umphumela wokuntanta kwezimayini zegolide.
