Iqhaza Le-Copper Sulfate Embonini Yokucubungula Izimbiwa

Emkhakheni oyinkimbinkimbi futhi obalulekile we Ukucutshungulwa kwamaminerali, ama-reagents ahlukahlukene amakhemikhali adlala indima ebalulekile ekuthuthukiseni ukuhlukaniswa kanye nokukhipha amaminerali abalulekile. I-Copper sulfate, enezici zayo zamakhemikhali ezihlukile, iye yavela njenge-reagent ebaluleke kakhulu kule mboni. Lesi sihloko sicubungula imisebenzi ehlukene ye I-Copper sulfate ekucutshungulweni kwezimbiwa, ukuhlola izindlela zayo nezindlela ezisetshenziswa ngayo.

Ukusebenza Kwezimbiwa

Enye yezindima eziyinhloko nezaziwa kakhulu ze-copper sulfate ekucubunguleni amaminerali umsebenzi wayo njenge-activator. Ku-sulfide ore Ukuqothula, ngokwesibonelo, inokuphawulekayo Ukuqalisa umphumela kumaminerali amaningana njenge-sphalerite, i-stibnite, i-pyrite, ne-pyrrhotite, enomthelela onamandla ikakhulukazi ku-sphalerite.

Izindlela Zokuvula

1.Ukusabela Kwe-Metathesis Ukwakha Ifilimu Yokuqalisa

Lapho i-sulfate yethusi isetshenziselwa ukuvula i-sphalerite, ukusabela kwe-metathesis kwenzeka. I-radius yama-ion e-copper e-divalent ifana ne-zinc ions, futhi ukuncibilika kwe-copper sulfide kuncane kakhulu kunaleyo ye-zinc sulfide. Ngenxa yalokho, ungqimba lwefilimu ye-copper sulfide lungakhiwa ebusweni be-sphalerite. Ngemva kokwakhiwa kwefilimu ye-sulfide yethusi, ingaxhumana kalula nayo Abaqoqi njengama-xanthates. Ama-Xanthate anobudlelwane obuqinile be-sulfide yethusi, okuthuthukisa i-hydrophobicity ye-sphalerite surface, okwenza kube lula ukuthi i-mineral inamathisele kumabhamuza omoya futhi intante, ngaleyo ndlela isebenze i-sphalerite.

2.Ukukhipha Ama-inhibitors kanye Nokwenza Ifilimu Lokuvula

Kwezinye izimo, amaminerali angase avinjwe ezinye izinto. Ngokwesibonelo, nini I-Sodium Cyanide isetshenziswa njenge-inhibitor enqubweni ye-flotation, ingakha i-zinc ezinzile - i-cyanide I-ion eyinkimbinkimbi ebusweni be-sphalerite, ecindezela ukugeleza kwe-sphalerite. Kodwa-ke, i-copper - cyanide complex ions izinzile kune-zinc - cyanide complex ions. Lapho i-copper sulfate yengezwa ku-sphalerite slurry evinjwe i-cyanide, ama-cyanide radicals ebusweni be-sphalerite ayawa, bese ama-ion e-copper amahhala asabela nge-sphalerite ukwenza ifilimu yokuqalisa ye-copper sulfide, ngaleyo ndlela iphinde isebenze i-sphalerite.

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.
