Ukusetshenziswa kwe-Sodium Hexametaphosphate ku-Mineral Flotation

Isingeniso

I-mineral flotation iyindlela esetshenziswa kakhulu embonini yezimayini ukuhlukanisa amaminerali abalulekile kumaminerali e-ganggue. Incike ekwehlukeni kwezakhiwo ezingokomzimba nezamakhemikhali zezindawo zamaminerali. I-sodium hexametaphosphate, nesakhiwo sayo samakhemikhali esiyingqayizivele kanye nezakhiwo, ithole ukusetshenziswa okubalulekile kuyo I-mineral flotation izinqubo. Lesi sihloko sicubungula izici ezihlukahlukene zokusetshenziswa kwayo ku-mineral flotation.

Izici ze-Sodium Hexametaphosphate

I-sodium hexametaphosphate iyinhlanganisela ye-polymer engaphili. Ibonakala njengekristalu esobala engenambala noma impushana emhlophe. Incibilika kakhulu emanzini, futhi isixazululo sayo esinamanzi siyi-alkaline. Emoyeni, inezinga elithile le-hygroscopicity. Lezi zakhiwo zomzimba kanye namakhemikhali zibeka isisekelo sokusebenza kwayo ku-mineral flotation.

Izindima ku-Mineral Flotation

Ukucindezeleka

1.Ukuvinjelwa kweSilicate neCarbonate Minerals

• I-sodium hexametaphosphate iyasebenza ekuvimbeleni i-quartz namaminerali silicate. Ekuntanteni kwamanye ama-ores, njengalawo aqukethe i-feldspar ne-mica, ingakhanga phezu kwalawa mamineral silicate. Isibonelo, ekuntanteni kwe-zirconium ores, kunganciphisa ukuntanta kwe-feldspar ehlobene namanye amaminerali e-silicate gangue ngokukhangisa ezindaweni zawo.

• It also shows inhibitory effects on I-Carbonate minerals like calcite and limestone. In the flotation of phosphate ores where calcite is a common gangue mineral, I-sodium hexametaphosphate ingasabela nge-calcium ions endaweni ye-calcite. Yakha izinhlanganisela ezizinzile ezikhulisa i-hydrophilicity yendawo ye-calcite, okwenza kube mancane amathuba okuthi inamathiselwe ngumqoqi, ngaleyo ndlela kufezwe injongo yokuvimbela.

2.Indlela Yokuvimbela

• Enye yezindlela eziyinhloko zokuvimbela ihlobene nokusabela kwayo ngama-ion ensimbi endaweni yamaminerali. Uma kukhulunywa ngamaminerali aqukethe ama-ion ensimbi amaningi ane-valent, i-sodium hexametaphosphate ingakha amakhompiyutha azinzile ngala ma-ion ensimbi. Ku-nickel ore flotation, ihlangana nama-ion athile ebusweni benyoka, okuvimbela ukuntanta kwenyoka.

• Ngaphezu kwalokho, kusixazululo esinamanzi, i-sodium hexametaphosphate ingaba ionize. Ingasabela nge-calcium ions endaweni yamaminerali kanye nesigaba soketshezi. Ekuhlukaniseni i-calcite ne-cassiterite, inhlanganisela eyenziwe endaweni ye-calcite ayithinti nje kuphela i-calcite kodwa futhi ingase ikhange endaweni ye-cassiterite, inciphise ukukhethwa kokuvinjelwa futhi inciphise ukukhangiswa komqoqi endaweni yamaminerali.

Ukuhlakazeka

1.Ukuhlakazwa kwe-Mineral Pulp

• Ezinqubweni zokuntanta, ikakhulukazi kwamanye ama-ores anamaminerali acolisekile noma ama-ores odaka - okuqukethwe okuphezulu, ukuhlakazeka kwe-pulp yamaminerali kubalulekile. I-sodium hexametaphosphate ingadlala indima ebalulekile njenge-dispersant. Isibonelo, ekuntanteni kwe-nickel - i-pyrite ores ehlotshaniswa ne-serpentine, ukwengeza inani elifanele le-sodium hexametaphosphate kungahlakaza i-pulp flotation. Lokhu kungenxa yokuthi kunciphisa ukumbozwa kwe-serpentine ebusweni be-nickel - pyrite, okuzuzisa ukubuyiswa kwe-flotation ye-nickel - pyrite.

2.Indlela Yokuhlakazeka

• I-sodium hexametaphosphate inganciphisa amandla angaphezulu amaminerali. Ngenxa yalokho, amandla e-electrostatic repulsive phakathi kwezinhlayiya zamaminerali ayanda. Isakhiwo sayo samangqamuzana, inhlanganisela ye-polymer ewumugqa enobude beketango okungenani lamayunithi angama-20 - 100, lapho ikhangisiwe endaweni yamaminerali, ingaphinda ikhulise umphumela wokuvinjwa kwesteric phakathi kwezinhlayiya. Ekuntanteni kwamanye ama-phosphate ores amahle, lo mphumela wokuhlakazeka ungavimbela ukuhlanganiswa kwe-phosphate kanye namaminerali e-ganggue, kuthuthukise ukusebenza kahle kokuhlukana.

Isicelo in Different Mineral Flotation

I-Phosphate Ore Flotation

1.Ukuhlukana Okukhethiwe

• Ku-phosphate ore flotation, i-sodium hexametaphosphate ivame ukusetshenziselwa ukuhlukanisa amaminerali e-phosphate kumaminerali e-ganggue. I-Phosphate ores ivame ukuhlotshaniswa namaminerali ahlukahlukene e-ganggue njenge-calcite, i-dolomite, namaminerali e-silicate. I-sodium hexametaphosphate ingavimbela ngokukhetha la maminerali e-ganggue. Enqubweni ye-flotation ehlanekezayo yamanye ama-phosphate ore, ukwengeza inani elincane le-sodium hexametaphosphate kungakhuphula ngempumelelo izinga kanye nokubuyiselwa kokugxila kwe-phosphate. Ingasabela ngamaminerali angewona ama-phosphate ngaphandle kokusabela ngamaminerali e-phosphate, ngaleyo ndlela ithuthukise ukukhethwa kwe-phosphate mineral flotation.

2.Umthelela ekuzinzeni kweFoam

• Kuphinde kube nomthelela ekuzinzeni kwegwebu ku-phosphate ore flotation. Igwebu enqubweni yokuntanta lidlala indima ekuqoqeni amaminerali e-phosphate. I-sodium hexametaphosphate ingathuthukisa ukuzinza kwegwebu. Ingakwazi ukukhiqiza inani elikhulu lamagwebu azinzile, okusiza ukuthuthukisa umphumela wokuqoqwa kwamaminerali e-phosphate. Amaminerali e-phosphate angathwalwa kangcono yigwebu elizinzile liye phezulu, ngaleyo ndlela athuthukise ukusebenza kahle kwe-flotation kanye nebanga.

Okungeyona - I-Flotation ye-Frorous Metal Ore

1.I-Nickel Ore Flotation

• Njengoba kushiwo ngaphambili, ku-nickel ore flotation, i-sodium hexametaphosphate isetshenziselwa ikakhulukazi ukuvimbela inyoka. I-Serpentine iyiminerali evamile ye-ganggue ku-nickel ores, futhi ukuba khona kwayo kungathinta ukuntanta kwamaminerali aqukethe i-nickel. Ngokungeza i-sodium hexametaphosphate, ingasabela ngama-ion ensimbi ebusweni benyoka, inciphise ukuntanta kwayo futhi ithuthukise ukuhlukaniswa kwe-nickel - aqukethe amaminerali enyoka. Lokhu kunenzuzo ekwenzeni ngcono izinga kanye nokubuyiselwa kokugxilisa kwe-nickel.

2.Ithusi kanye nomthofu - I-Zinc Ore Flotation

• Ku-copper kanye nomthofu - i-zinc ore flotation, uma kune-calcium ehambisanayo - equkethe amaminerali e-ganggue afana ne-calcite ne-dolomite, i-sodium hexametaphosphate ingasetshenziswa ukuvimbela lamaminerali e-ganggue. Kwezinye ithusi eliyinkimbinkimbi - i-lead - zinc ores, ukulungisa inani le-sodium hexametaphosphate kungalawula ngempumelelo ukuntanta kwamaminerali e-ganggue, ukuthuthukisa ukukhetha kokuntanta kanye nekhwalithi yethusi, i-lead, ne-zinc igxile.

Izinto Ezithinta Umphumela Wohlelo

Isikali

1.Optimal Dosage Ukunqunywa

• Umthamo we-sodium hexametaphosphate unomthelela omkhulu ekusebenzeni kwayo ku-mineral flotation. Umthamo ongalungile ungase uholele emiphumeleni engcono kakhulu. Uma umthamo uphansi kakhulu, ungase ungavimbi ngempumelelo amaminerali e-ganggue noma uhlakaze uginindela. Isibonelo, ku-phosphate ore flotation, uma inani le-sodium hexametaphosphate elengeziwe linganele, amaminerali e-ganggue angase angavinjelwa kahle, okuholela ebangeni eliphansi lokugxila kwe-phosphate.

• Ngakolunye uhlangothi, uma umthamo uphezulu kakhulu, angeke nje ukwandisa izindleko kodwa futhi kubangele imiphumela emibi. Kwezinye izimo, i-sodium hexametaphosphate eyeqile ingase futhi ivimbele amaminerali aqondiwe ngokwezinga elithile, kwehlise izinga lokululama. Ngakho-ke, ukunquma umthamo ophelele ngocwaningo lokuhlola kanye nokulungiswa kwamaphutha esizeni kubalulekile ukuze kuzuzwe imiphumela ehamba phambili yokuntanta.

I-pH Inani le-Pulp

2.Ithonya Ekuphenduleni Kwamakhemikhali

• Inani le-pH le-pulp ye-flotation lithinta ukusabela kwamakhemikhali e-sodium hexametaphosphate. Ezindaweni ezihlukene ze-pH, izinga le-ionization kanye nohlobo lwamakhemikhali lwe-sodium hexametaphosphate lungashintsha. Endaweni ene-asidi, umphumela wawo ovimbelayo kwamanye amaminerali ungase ube buthakathaka. Endaweni ene-alkaline kakhulu, ingase ihlangane nezinye izinto ku-pulp, ithinte umsebenzi wayo ovamile. Isibonelo, ekuntanteni kwamanye ama-copper - lead - ore ye-zinc, ukugcina inani le-pH elifanele (imvamisa lizungeze u-8 - 10) kungaqinisekisa ukuthi i-hexametaphosphate ye-sodium ivimbela ngempumelelo amaminerali e-ganggue futhi ikhuthaze ukuntanta kwamaminerali aqondiwe.

Isiphetho

I-sodium hexametaphosphate idlala izindima eziningi ezibalulekile ku-flotation yamaminerali, okuhlanganisa njenge-a Ukucindezeleka kanye nesihlakaniphi. Ukusetshenziswa kwayo ezinhlotsheni ezahlukene ze-mineral flotation, njenge-phosphate ore kanye ne-non-ferrous metal ore flotation, kuthuthukise kakhulu ukusebenza kahle kanye nekhwalithi yokuhlukaniswa kwamaminerali. Kodwa-ke, ukuze usebenzise amandla ayo ngokugcwele, izici ezinjengomthamo kanye ne-pulp pH zidinga ukulawulwa ngokucophelela. Ngokuthuthuka okuqhubekayo kwemboni yezimayini, ucwaningo olwengeziwe mayelana nokusetshenziswa kwe-sodium hexametaphosphate ku-mineral flotation lungaholela ezindleleni ezisebenza kahle nezimeme zokucubungula amaminerali.
