Ongororo pfupi yebasa remhangura sulfate mune ore Beneficiation uye flotation

Copper sulfate, iyo inoratidzika sebhuruu kana yebhuruu-girini makristasi, inoshandiswa zvakanyanya activator mune sulfide ore flotation.Inonyanya kushandiswa se activator, regulator uye inhibitor kugadzirisa pH kukosha kwe slurry, kudzora furo chizvarwa uye kuvandudza Kugona kwepamusoro kwemaminerari kune activation effect pane sphalerite, stibnite, pyrite uye pyrrhotite, kunyanya sphalerite iyo inodziviswa neraimu. kana cyanide.

Basa remhangura sulfate mune mineral flotation:

1. Inoshandiswa se activator

Inogona kushandura zvinhu zvemagetsi zvemaminerari enzvimbo uye kuita mamineral surfaces hydrophilic.Iyi hydrophilicity inogona kuwedzera nzvimbo yekubatana pakati pemaminerari nemvura, zvichiita kuti zvive nyore kuti mineral iyangarara.Copper sulfate inogonawo kuumba cations mune mineral slurry, iyo inowedzera adsorbed pamusoro peiyo mineral, ichiwedzera hydrophilicity uye buoyancy.

Iyo activation mechanism inosanganisira zvinhu zviviri zvinotevera:

①.Metathesis reaction inoitika pamusoro peiyo activated mineral kuti iite activation firimu.Semuenzaniso, copper sulfate inoshandiswa kuita sphalerite.Iyo radius ye divalent copper ions yakafanana neradius ye zinc ions, uye solubility yemhangura sulfide idiki zvakanyanya pane iyo zinc sulfide.Nokudaro, firimu yemhangura sulfide inogona kuumbwa pamusoro pe sphalerite.Mushure mokunge firimu yemhangura ye sulfide yakaumbwa, inogona kuwirirana nyore nyore ne xanthate muunganidzi, kuitira kuti sphalerite ishandiswe.

②.Bvisa inhibitor kutanga, uye wozogadzira firimu rekuita.Apo sodium cyanide inhibits sphalerite, yakagadzikana zinc cyanide ions inoumbwa pamusoro pe sphalerite, uye copper cyanide ions inogadzikana kupfuura zinc cyanide ions.Kana mhangura sulfate yakawedzerwa kune sphalerite slurry iyo inodziviswa ne cyanide, iyo cyanide radicals pamusoro pe sphalerite ichawa, uye iyo yemahara mhangura ions ichaita pamwe ne sphalerite kuumba activation firimu yemhangura sulfide, nekudaro activating the sphalerite.

2. Inoshandiswa semutongi

Iyo pH kukosha kwe slurry inogona kugadziriswa.Paukoshi hwakakodzera hwepH, copper sulfate inokwanisa kuita nehydrogen ions pane mineral surface kuti igadzire zvinhu zvemakemikari zvinosanganiswa neine mineral surface, zvichiwedzera hydrophilicity uye buoyancy yemaminerari, nekudaro ichisimudzira kuyerera kwemigodhi yegoridhe.

3. Inoshandiswa se inhibitor

Anions inogona kuumbwa mune slurry uye adsorbed pamusoro pezvimwe zvicherwa zvisingade kutenderera, zvichideredza hydrophilicity yavo uye buoyancy, nekudaro kudzivirira zvicherwa izvi kubva pakuyangarara pamwe chete nemaminerari egoridhe.Copper sulfate inhibitors inowanzowedzerwa kune slurry kuchengetedza zvicherwa zvisingade kutenderera pasi.

4. Inoshandiswa se mineral surface modifier

Shandura makemikari uye emuviri zvimiro zvemamineral surface.Mune goridhe ore flotation, zvivakwa zvemagetsi uye hydrophilicity yemaminerari pamusoro zvinhu zvakakosha zvekufambisa.Copper sulfate inogona kuumba copper oxide ions mumineral slurry, inopindirana nesimbi ions pamusoro pemaminerari, uye inoshandura nzvimbo yayo yemakemikari.Copper sulfate inogona zvakare kushandura iyo hydrophilicity yemaminerari epasi uye kuwedzera nzvimbo yekubatana pakati pezvicherwa nemvura, nekudaro ichisimudzira flotation maitiro emigodhi yegoridhe.
