Iqhaza Le-Copper Sulfate Embonini Yokucubungula Izimbiwa

Emkhakheni oyinkimbinkimbi nobalulekile wokucubungula amaminerali , ama-reagent amakhemikhali ahlukahlukene adlala indima ebalulekile ekwenzeni ngcono ukuhlukaniswa nokukhishwa kwamaminerali ayigugu. I-Copper sulfate, enezakhiwo zayo ezihlukile zamakhemikhali, ivele njenge-reagent ebaluleke kakhulu kule mboni. Lesi sihloko sihlola imisebenzi eminingi ye- Copper sulfate ekucubungulweni kwamaminerali, sihlola izindlela zayo kanye nokusetshenziswa kwayo.

Ukusebenza Kwezimbiwa

Enye yezindima eziyinhloko nezaziwa kakhulu ze-copper sulfate ekucutshungulweni kwamaminerali umsebenzi wayo njenge-activator. Ku-sulfide ore Flotation , isibonelo, inomphumela ophawulekayo wokusebenza kumaminerali amaningana afana ne-sphalerite, i-stibnite, i-pyrite, ne-pyrrhotite, onomthelela oqinile kakhulu ku-sphalerite.

Izindlela Zokuvula

1.Ukusabela Kwe-Metathesis Ukwakha Ifilimu Yokuqalisa

Uma kusetshenziswa i-copper sulfate ukwenza i-sphalerite isebenze, kwenzeka ukusabela kwe-metathesis. Irediyasi yama-ion e-copper ahlukene ifana neyama-ion e-zinc, futhi ukuncibilika kwe-copper sulfide kuncane kakhulu kunokwe-zinc sulfide. Ngenxa yalokho, ungqimba lwefilimu ye-copper sulfide lungakhiwa phezu kobuso be-sphalerite. Ngemva kokuba ifilimu ye-copper sulfide yakhekile, ingasebenzisana kalula nama -Collectors afana nama-xanthates. Ama-Xanthates anobuhlobo obuqinile be-copper sulfide, okuthuthukisa ukungazinzi kwamanzi kobuso be-sphalerite, okwenza kube lula ukuthi i-mineral inamathele kuma-bubbles omoya futhi intante, ngaleyo ndlela isebenze i-sphalerite.

2.Ukukhipha Ama-inhibitors kanye Nokwenza Ifilimu Lokuvula

Kwezinye izimo, amaminerali angase avinjelwe ezinye izinto. Isibonelo, lapho i-Sodium Cyanide isetshenziswa njengesivimbeli enqubweni yokuntanta, ingakha ama-ion aqinile e-zinc - cyanide complex ebusweni be-sphalerite, okucindezela ukuntanta kwe-sphalerite. Kodwa-ke, ama-ion aqinile e-copper - cyanide azinzile kakhulu kune-ion aqinile e-zinc - cyanide. Lapho i-copper sulfate ingezwa ku-slurry ye-sphalerite evinjelwe yi-cyanide, ama-radical e-cyanide ebusweni be-sphalerite ayawa, bese ama-ion e-copper amahhala abese esabela ne-sphalerite ukuze akhe ifilimu yokwenza i-copper sulfide isebenze, ngaleyo ndlela avuselele i-sphalerite ukuze intantanta intante.

Ukulawulwa kwe-Slurry pH

I-Copper sulfate iphinde isebenze njengomlawuli ku-slurry yokucubungula amaminerali, ikakhulukazi mayelana nokulungiswa kwe-pH. Inani le-pH le-slurry liyisici esibalulekile esithinta izakhiwo ezingaphezulu zamaminerali kanye nokusebenza kwama-reagents e-flotation.

Lapho i-copper sulfate yengezwa ku-slurry, ingangena emanzini. I-sulfuric acid ewumphumela ingakhuphula ukugxila kwe-hydrogen ion ku-slurry, ngaleyo ndlela yehlise inani le-pH. Ngenani elifanele le-pH, i-copper sulfate ingasabelana nama-ion e-hydrogen endaweni yamaminerali ukuze kwakhe izinto zamakhemikhali ezihlangana ne-mineral surface. Lokhu kusabela kungakhuphula i-hydrophilicity kanye ne-buoyancy yamaminerali, kukhuthaze umphumela wokuntanta. Isibonelo, kwamanye ama-ores anegolide, ukulungisa i-pH ye-slurry nge-copper sulfate kungathuthukisa ukusebenzisana phakathi kwamaminerali aphethe igolide nabaqoqi, ukuthuthukisa ukutholakala kwegolide ukuntanta.

Ukuvinjelwa Kwamaminerali Angadingeki

Ngaphezu kokusebenza, i-copper sulfate nayo ingasebenza njenge-inhibitor ezimweni ezithile. Enqubweni yokuntanta, ngokuvamile kuyadingeka ukuhlukanisa amaminerali okuhlosiwe kwamanye amaminerali angadingeki. I-Copper sulfate ingasetshenziswa ukuvimbela ukuntanta kwamaminerali angahlosiwe.

Uma ingezwe ku-slurry, i-copper sulfate ingenza ama-anion adsorbed phezu kwamanye amaminerali angadingi ukuntanta. Lokhu kukhangisa kunciphisa i-hydrophilicity kanye nokuvuthwa kwalawa maminerali angahlosiwe, okuvimbele ukuthi angantanti kanye namaminerali aqondiwe. Isibonelo, ohlelweni lokuntanta lapho inhloso kuwukuhlukanisa amaminerali egolide kumaminerali athile e-ganggue, ukwengeza i-copper sulfate inhibitors ku-slurry kungagcina amaminerali e-ganggue phansi kweseli le-flotation ngenkathi kuvumela amaminerali egolide ukuba antante phezulu ngosizo lwabaqoqi kanye namabhamuza.

Ukuguqulwa Kwezindawo Zamaminerali

I-Copper sulfate ingasebenza njenge-mineral surface modifier, iguqule izakhiwo zamakhemikhali nezomzimba zezindawo zamaminerali. Ekuntanteni kwensimbi yegolide, izakhiwo zikagesi kanye ne-hydrophilicity yendawo yamaminerali yizinto ezibalulekile ezithinta ukusebenza kahle kokuntanta.

Ku-mineral slurry, i-sulfate yethusi ingakha ithusi - i-ions equkethe. Lawa ma-ion angakwazi ukusebenzisana nama-ion ensimbi ebusweni be-mineral, aguqule izici zayo zamakhemikhali ezingaphezulu. Isibonelo, ebusweni bamanye amaminerali anegolide anongqimba oluthile lwe-oxide, ama-ion ethusi - aqukethe angasabelana nama-ion ensimbi ongqimba lwe-oxide, enze inhlanganisela yamakhemikhali amasha phezulu. Lokhu kungashintsha ukushaja okungaphezulu kanye nokusebenza kabusha kwamakhemikhali kumaminerali.

Ngaphezu kwalokho, i-copper sulfate nayo ingathinta i-hydrophilicity yezindawo zamaminerali. Ngokwandisa indawo yokuxhumana phakathi kwamaminerali namanzi, ingathuthukisa ukuhlakazeka kwamaminerali odaka. Lokhu kuhlakazeka okuthuthukisiwe kungaba yinzuzo esenzweni esilandelayo sabaqoqi. Lapho abaqoqi bengezwa, bangasebenzisana ngempumelelo kakhulu nezindawo zamaminerali ezilungisiwe, bakhuthaze ukunamathiselwa kwamaminerali kumabhamuza omoya futhi ekugcineni bathuthukise umphumela wokuntanta kwezimayini zegolide.

Isiphetho

Kafushane, i-copper sulfate idlala indima ehlukahlukene futhi ebalulekile embonini yokucubungula izimbiwa. Njenge-activator, ingathuthukisa kakhulu ukusebenza kwe-flotation yamaminerali afana ne-sphalerite ngokwenza amafilimu okusebenza noma ukususa ama-inhibitors. Njengomlawuli, kusiza ukukhulisa i-pH ethambile, ebalulekile ekusebenzeni kahle kwenqubo yokuntanta. Njenge-inhibitor, ingavimbela ngokukhetha ukuntanta kwamaminerali angafuneki, ithuthukise ukuhlanzeka kokugxila kokugcina. Futhi njengesilungisi sendawo yamaminerali, ingashintsha izici zamakhemikhali nezomzimba zezindawo zamaminerali, ithuthukise ukusebenzisana phakathi kwamaminerali nama-reagents antantayo. Ukusetshenziswa ngendlela efanele kwe-copper sulfate ekucutshungulweni kwezimbiwa akugcini nje ngokuthuthukisa ukusebenza kahle kokuhlukaniswa kwezimbiwa kodwa futhi kufaka isandla ekusetshenzisweni okuzinzile nokonga kwemithombo yezimbiwa.
