Iko Kushandiswa kweSodium Hexametaphosphate muMineral Flotation

ziviso

Mineral flotation inzira inoshandiswa zvakanyanya muindasitiri yezvicherwa kuparadzanisa zvicherwa zvakakosha kubva kune gangue minerals. Inovimba nemisiyano yemuviri uye makemikari zvimiro zveminerari pamusoro. Sodium hexametaphosphate, ine yakasarudzika chimiro chemakemikari uye zvimiro, yakawana yakakosha maapplication mukati Mineral flotation maitiro. Ichi chinyorwa chinotarisa mune zvakasiyana-siyana zvekushandiswa kwayo mumineral flotation.

Zvinhu zveSodium Hexametaphosphate

Sodium hexametaphosphate is anorganic polymer compound. Inoratidzika sekristaro isina ruvara inoonekera kana hupfu chena. Inonyungudika zvakanyanya mumvura, uye mhinduro yayo ine aqueous ndeye alkaline. Mumhepo, ine imwe nhanho yehygroscopicity. Izvi zvemuviri uye zvemakemikari zvimiro zvinoisa hwaro hwekushanda kwayo mumineral flotation.

Mabasa muMineral Flotation

Kushungurudzika

1.Kuvharwa kweSilicate uye Carbonate Minerals

• Sodium hexametaphosphate inoshanda mukudzivisa quartz uye silicate minerals. Mukutenderera kwemamwe ores, akadai seaya ane feldspar uye mica, anogona adsorb pamusoro peaya silicate minerals. Semuenzaniso, mukuyangarara kwe zirconium ores, inogona kuderedza kutenderera kweyakabatana feldspar uye mamwe silicate gangue zvicherwa nekushambadza pamusoro penzvimbo yavo.

• Inoratidzawo mhedzisiro yekudzivirira pa kabhonivakadya zvicherwa zvakaita se calcite ne limestone. Mukufamba kwe phosphate ores uko calcite iri gangue mineral yakajairika, Sodium hexametaphosphate inogona kuita ne calcium ions pane calcite pamusoro. Iyo inoumba maumbirwo akagadzikana anowedzera hydrophilicity ye calcite pamusoro, zvichiita kuti isanyanya kusungirirwa nemuunganidzi, nokudaro kuzadzisa chinangwa chekudzivisa.

2.Inhibition Mechanism

• Imwe yenzira huru dzekuvharisa ine chekuita nekuita kwayo nesimbi ions pane mineral surface. Kana zvasvika kune zvicherwa zvine akawanda-valent simbi ions, sodium hexametaphosphate inogona kuumba yakagadzikana makomisheni neaya simbi ions. Mune nickel ore flotation, inopindirana nemaion chaiwo pamusoro penyoka, iyo inodzivisa kubhururuka kwenyoka.

• Mukuwedzera, mumushonga wemvura, sodium hexametaphosphate inogona ionize. Inogona kuita ne calcium ions muminerari pamusoro uye chikamu chemvura. Mukuparadzaniswa kwe calcite uye cassiterite, musanganiswa wakaumbwa pamusoro pe calcite haungokanganisa calcite chete asiwo unogona kushambadza pane cassiterite pamusoro, kuderedza kusarudzwa kwekudzivirira uye kuderedza kushambadza kwemuunganidzi pane mineral surface.

Dispersant

1.Kupararira kweMineral Pulp

• Mukuita zvekuyangarara, kunyanya kune mamwe ores ane yakanaka - yakachekwa zvicherwa kana yakakwira - madhaka - emukati ores, kupararira kweiyo mineral pulp kwakakosha. Sodium hexametaphosphate inogona kuita basa rakakosha se dispersant. Semuyenzaniso, ari flotation nickel - pyrite ores chokuita nyoka, kuwedzera zvakakodzera uwandu sodium hexametaphosphate anogona kuparadzira flotation pulp. Izvi zvinodaro nekuti inoderedza kuvharwa kwe nyoka pamusoro pe nickel - pyrite, iyo inobatsira kune flotation kupora kwe nickel - pyrite.

2.Dispersion Mechanism

• Sodium hexametaphosphate inogona kuderedza kugona kwepamusoro kwemaminerari. Nekuda kweizvozvo, iyo electrostatic repulsive force pakati pemamineral particles inowedzera. Yayo mamorekuru chimiro, mutsara wepolymer musanganiswa une cheni kureba ingangoita 20 - 100 mayunitsi, kana adsorbed pane mineral surface, anogona zvakare kuwedzera steric chipingamupinyi mhedzisiro pakati pezvimedu. Mukutenderera kweimwe yakanaka-yakaomeswa phosphate ores, iyi dispersion mhedzisiro inogona kudzivirira kuunganidzwa kwephosphate uye gangue zvicherwa, kuvandudza kugona kwekuparadzanisa.

Kushandisa mune Yakasiyana Mineral Flotation

Phosphate Ore Flotation

1.Selective Separation

• Mune phosphate ore flotation, sodium hexametaphosphate inowanzoshandiswa kuparadzanisa phosphate minerals kubva kune gangue minerals. Phosphate ores inowanzobatanidzwa neakasiyana gangue zvicherwa senge calcite, dolomite, uye silicate zvicherwa. Sodium hexametaphosphate inogona kusarudza kuvharira aya gangue minerals. Mune reverse flotation process yemamwe phosphate ores, kuwedzera shoma shoma yesodium hexametaphosphate inogona zvinobudirira kuwedzera giredhi uye kudzoreredza kwefosfate concentrate. Inogona kuita neasiri-phosphate zvicherwa pasina kuita nemamineral phosphate, nekudaro ichivandudza kusarudzwa kwephosphate mineral flotation.

2.Effect paFoam Kugadzikana

• Izvo zvakare zvine chekuita nekugadzikana kwefuro muphosphate ore flotation. Iyo furo mu flotation process inoita basa mukuunganidza phosphate minerals. Sodium hexametaphosphate inogona kuwedzera kugadzikana kwefuro. Inogona kuburitsa huwandu hukuru hwemafuro akagadzikana, ayo anobatsira kuvandudza kuunganidzwa kwemaitiro emaminerari ephosphate. Iyo phosphate zvicherwa inogona kutakurwa zvirinani nefuro yakagadzikana kuenda pamusoro, nekudaro ichivandudza flotation kunyatsoita uye giredhi.

Kwete - Ferrous Metal Ore Flotation

1.Nickel Ore Flotation

• Sezvambotaurwa, mu nickel ore flotation, sodium hexametaphosphate inonyanya kushandiswa kuvharidzira nyoka. Serpentine inowanzoita gangue mineral mu nickel ores, uye kuvapo kwayo kunogona kukanganisa kutenderera kwe nickel - kubereka zvicherwa. Nokuwedzera sodium hexametaphosphate, inogona kuita nesimbi ions pamusoro penyoka, kuderedza kutenderera kwayo uye kunatsiridza kupatsanurwa kwenickel - inotakura zvicherwa kubva nyoka. Izvi zvinobatsira pakuvandudza giredhi uye kudzoreredza nickel inosimbisa.

2.Mhangura uye Lead - Zinc Ore Flotation

• Mumhangura nemutobvu - zinc ore flotation, kana paine calcium yakabatana - ine gangue zvicherwa zvakaita secalcite uye dolomite, sodium hexametaphosphate inogona kushandiswa kuvharidzira maminerari aya. Mune dzimwe dzakaoma mhangura - lead - zinc ores, kugadzirisa huwandu hwesodium hexametaphosphate inogona kunyatso kudzora kutenderera kwemaminerari e gangue, kunatsiridza kusarudzwa kwekuyerera uye kunaka kwemhangura, lead, uye zingi inotarisana.

Zvinhu Zvinokanganisa Kushanda Mhedzisiro

Dosage

1.Optimal Dosage Kutsunga

• Muyero wesodium hexametaphosphate ine mhedzisiro yakakura pakuita kwayo mumamineral flotation. Dose isina kufanira inogona kutungamira kune sub - optimal mhedzisiro. Kana muyero wacho wakanyanya kuderera, haugone kuvharira zvicherwa zve gangue kana kuparadzira pulp. Semuenzaniso, mune phosphate ore flotation, kana huwandu hwesodium hexametaphosphate yakawedzerwa isina kukwana, iyo gangue minerals inogona kunge isina kuvharwa zvakanaka, zvichikonzera yakaderera giredhi yefosfate concentrate.

• Nekune rumwe rutivi, kana muyero wacho wakanyanya kukwirira, haungango wedzera mari chete asiwo uchikonzera zvimwe zvakaipa. Mune zvimwe zviitiko, yakawandisa sodium hexametaphosphate inogonawo kuvharidzira chinangwa chezvicherwa kune imwe nhanho, kuderedza chiyero chekudzorera. Naizvozvo, kuona iyo yakakwana dosage kuburikidza nekuyedza tsvakiridzo uye pa-saiti debugging kwakakosha kuti uwane yakanakisa flotation mhedzisiro.

pH Kukosha kwePulp

2.Kufurira pane Chemical Reactions

• Iyo pH kukosha kweiyo flotation pulp inokanganisa maitiro emakemikari e sodium hexametaphosphate. Munzvimbo dzakasiyana dzepH, iyo ionization degree uye chimiro chemakemikari sodium hexametaphosphate inogona kuchinja. Munzvimbo ine acidic, iyo inhibitory mhedzisiro pane mamwe mamineral inogona kuderedzwa. Munzvimbo ine alkaline yakanyanya, inogona kuita pamwe nezvimwe zvinhu zviri munyama, zvichikanganisa kushanda kwayo kwakaringana. Semuenzaniso, mukutenderera kweimwe mhangura - lead - zinc ores, kuchengetedza iyo yakakodzera pH kukosha (kazhinji yakatenderedza 8 - 10) inogona kuve nechokwadi chekuti sodium hexametaphosphate inonyatso inhibits gangue minerals uye inosimudzira kutenderera kwechinangwa chezvicherwa.

mhedziso

Sodium hexametaphosphate inotamba akawanda akakosha mabasa mumineral flotation, kusanganisira sea Kushungurudzika uye muparadzi. Mashandisirwo ayo mumhando dzakasiyana dzemaminerari flotation, senge phosphate ore uye isiri-ferrous simbi ore flotation, yakavandudza zvakanyanya kushanda uye kunaka kwekuparadzaniswa kwemaminerari. Nekudaro, kuti ishandise zvizere kugona kwayo, zvinhu zvakaita seyero uye pulp pH zvinoda kunyatsodzorwa. Nekuenderera mberi kwekusimudzira indasitiri yezvicherwa, kumwe kutsvagisa pamusoro pekushandiswa kwesodium hexametaphosphate mumaminerari flotation kunogona kutungamira kune inoshanda uye yakagadzikana nzira dzekugadzirisa zvicherwa.
