Basa reCopper Sulfate muMineral Processing Indasitiri

Mundima yakaoma uye yakakosha ye Mineral processing, akasiyana makemikari reagents anoita basa rakakosha mukugadzirisa kupatsanurwa uye kutorwa kwemaminerari akakosha. Copper sulfate, ine akasiyana makemikari zvimiro, yakabuda seyakanyanya kukosha reagent muindasitiri iyi. Ichi chinyorwa chinotarisa mumabasa ane mativi mazhinji e Mhangura sulfate mukugadzirisa zvicherwa, kuongorora maitiro ayo uye mashandisirwo.

Activation of Minerals

Rimwe rekutanga uye rinonyanya kuzivikanwa mabasa emhangura sulfate mukugadziriswa kwemaminerari ibasa rayo se activator. Mune sulfide ore Flotation, semuenzaniso, ine zvinoshamisa Activation mhedzisiro pamaminerari akati wandei akadai se sphalerite, stibnite, pyrite, uye pyrrhotite, ine yakanyanya kusimba pane sphalerite.

Activation Mechanisms

1.Metathesis Reaction Kugadzira Firimu Yekuita

Kana copper sulfate inoshandiswa kuita sphalerite, metathesis reaction inoitika. Iyo radius ye divalent copper ions yakafanana neiyo zinc ions, uye kunyungudika kwemhangura sulfide idiki zvakanyanya pane iyo zinc sulfide. Somugumisiro, chidimbu chemhangura sulfide firimu inogona kuumbwa pamusoro pe sphalerite. Mushure mokunge firimu yemhangura sulfide yakaumbwa, inogona kushamwaridzana nyore nyore nayo Vanounganidza zvakadai se xanthates. Xanthates ine hukama hwakasimba hwemhangura sulfide, iyo inowedzera hydrophobicity ye sphalerite pamusoro, zvichiita kuti zvive nyore kuti mineral ibatanidze kumhepo inoputika uye inoyangarara, nekudaro ichimisa sphalerite.

2.Kubvisa Inhibitors uye Kugadzira Firimu Yekuita

Mune zvimwe zviitiko, zvicherwa zvinogona kudziviswa nezvimwe zvinhu. Somuenzaniso, apo Sodium Cyanide inoshandiswa se inhibitor mu flotation process, inogona kuita yakagadzikana zinc - cyanide ions yakaoma pamusoro pe sphalerite, iyo inodzvinyirira kutenderera kwe sphalerite. Zvisinei, copper - cyanide complex ions yakagadzikana kudarika zinc - cyanide complex ions. Kana copper sulfate ichiwedzerwa kune sphalerite slurry yakavharwa ne cyanide, iyo cyanide radicals pamusoro pe sphalerite inowira pasi, uye iyo yakasununguka yemhangura ions inobva yaita ne sphalerite kuti iite activation firimu yemhangura sulfide, nokudaro zvakare - activating iyo sphalerite ye sphalerite.

Mutemo weSlurry pH

Copper sulfate inoshandawo semutongi mune mineral processing slurry, kunyanya maererano nepH kugadzirisa. Iyo pH kukosha kweiyo slurry chinhu chakakosha chinokanganisa nzvimbo dzepamusoro dzemaminerari uye kuita kwema flotation reagents.

Kana copper sulfate yakawedzerwa kune slurry, inogona kupinda hydrolysis mumvura. Iyo inokonzeresa sulfuric acid inogona kuwedzera iyo hydrogen ion concentration mune slurry, nekudaro ichidzikisa iyo pH kukosha. Paukoshi hwakakodzera hwepH, copper sulfate inokwanisa kuita nehydrogen ions pane mineral surface kuti iumbe zvinhu zvemakemikari zvinosangana neine mineral surface. Kuita uku kunogona kuwedzera hydrophilicity uye buoyancy yemaminerari, ichisimudzira iyo flotation effect. Semuenzaniso, mune imwe goridhe - inotakura ores, kugadzirisa pH ye slurry nemhangura sulfate kunogona kuwedzera kudyidzana pakati pegoridhe - inotakura zvicherwa nevanotora, kuvandudza kudzoreredza kudzoreredza kwegoridhe.

Kudziviswa kweMinerari Isingadiwi

Mukuwedzera kune activation, mhangura sulfate inogonawo kushanda se inhibitor mune mamwe mamiriro ezvinhu. Muchifambiso chekuyerera, zvinowanzodiwa kuparadzanisa zvicherwa zvakanangwa kubva kune mamwe maminerari asingadiwi. Copper sulfate inogona kushandiswa kuvharidzira kuyerera kwemaminerari asina chinangwa.

Kana yawedzerwa kune slurry, copper sulfate inogona kuumba anions inoshambadzirwa pamusoro pemamwe maminerari asingade kutenderera. Iyi adsorption inodzikisira hydrophilicity uye buoyancy yeaya asiri-anotariswa zvicherwa, achidzivirira kuti asayangarara pamwe chete nemaminerari anotangwa. Semuyenzaniso, ari flotation hurongwa apo chinangwa ndiko kupatsanura goridhe zvicherwa kubva dzimwe gangue zvicherwa, kuwedzera mhangura sulfate inhibitors kuti slurry anogona kuchengeta gangue zvicherwa pazasi flotation sero uku achibvumira zvicherwa goridhe kuyangarara pamusoro pemvura nerubatsiro rwevateresi uye mabhuru.

Kugadziriswa kweMineral Surfaces

Copper sulfate inogona kuita semamineral surface modifier, ichichinja makemikari uye emuviri zvimiro zveminerari nzvimbo. Mune goridhe ore flotation, zvivakwa zvemagetsi uye hydrophilicity yenzvimbo yemaminerari zvinhu zvakakosha zvinokanganisa flotation kushanda zvakanaka.

Mune mineral slurry, mhangura sulfate inogona kuumba mhangura - ine ions. Aya maion anogona kuita neayoni esimbi ari pamusoro pechicherwa, achishandura chimiro chayo chemakemikari. Semuenzaniso, pamusoro peimwe goridhe - inotakura zvicherwa ine imwe oxide layer, mhangura - ine ions inogona kuita neiyoni yesimbi muokisidhi layer, ichigadzira mitsva yemakemikari pamusoro pepamusoro. Izvi zvinogona kushandura kubhadharisa kwepamusoro uye kemikari reactivity yemaminerari.

Uyezve, mhangura sulfate inogonawo kukanganisa hydrophilicity yemaminerari enzvimbo. Nekuwedzera nzvimbo yekubatana pakati pezvicherwa nemvura, inogona kuvandudza kupararira kwemaminerari mune slurry. Uku kupararira kwakawedzerwa kunogona kubatsira kune inotevera chiitiko chevaunganidzi. Kana vaunganidzi vawedzerwa, vanogona kunyatsopindirana neyakagadziridzwa maminerari, vachisimudzira kusungirirwa kwemaminerari kumabhuru emhepo uye pakupedzisira kugadzirisa flotation mhedzisiro yemigodhi yegoridhe.

mhedziso

Muchidimbu, mhangura sulfate inoita basa rakasiyana uye rakakosha muindasitiri yekugadzira zvicherwa. Se activator, inogona kuwedzera zvakanyanya kuita kweflotation yemaminerari senge sphalerite nekugadzira activation mafirimu kana kubvisa inhibitors. Semugadziri, inobatsira kukwirisa iyo slurry pH, iyo yakakosha pakushanda kwakaringana kweiyo flotation process. Se inhibitor, inogona kusarudza kudzivirira kuyerera kwemaminerari asingadiwe, ichivandudza kuchena kweiyo yekupedzisira kuisa pfungwa. Uye semamineral surface modifier, inogona kushandura kemikari uye yemuviri zvimiro zvemaminerari, ichiwedzera kudyidzana pakati pezvicherwa uye flotation reagents. Kushandiswa kwakakodzera kwemhangura sulfate mukugadziriswa kwemaminerari hakungogadzirise kugona kwekuparadzaniswa kwemaminerari asiwo kunobatsira mukugarisa uye kushandiswa kwehupfumi kwezvicherwa.
