Basa reCopper Sulfate muMineral Processing Indasitiri

Mundima yakaoma uye inokosha yekugadzirisa zvicherwa , ma reagents akasiyana-siyana emakemikari anoita basa rakakosha mukuvandudza kupatsanurwa nekuburitswa kwezvicherwa zvinokosha. Copper sulfate, ine hunhu hwayo hwakasiyana hwemakemikari, yave chinhu chakakosha zvikuru muindasitiri iyi. Chinyorwa chino chinotarisa mabasa eCopper sulfate mukugadzirisa zvicherwa, ichiongorora mashandiro ayo uye mashandisirwo ayo.

Activation of Minerals

Imwe yemabasa makuru uye anozivikanwa zvikuru e copper sulfate mukugadzirisa zvicherwa ibasa rayo se activator. Semuenzaniso, mu sulfide ore Flotation , ine simba rinoshamisa reActivation pazvicherwa zvakawanda zvakaita se sphalerite, stibnite, pyrite, uye pyrrhotite, ine simba rakasimba pa sphalerite.

Activation Mechanisms

1.Metathesis Reaction Kugadzira Firimu Yekuita

Kana copper sulfate ikashandiswa kumutsa sphalerite, panoitika metathesis reaction. Radius yema divalent copper ions yakafanana neye zinc ions, uye kunyunguduka kwe copper sulfide kudiki zvikuru pane kwe zinc sulfide. Nekuda kweizvozvo, layer ye copper sulfide film inogona kuumbwa pamusoro pe sphalerite. Mushure mekunge copper sulfide film yagadzirwa, inogona kusangana zviri nyore neCollectors dzakadai se xanthates. Xanthates dzine hukama hwakasimba ne copper sulfide, izvo zvinowedzera hydrophobicity ye sphalerite surface, zvichiita kuti zvive nyore kuti mineral ibatanidzwe kumabubbles emhepo uye iyangarare, nokudaro ichimutsa sphalerite.

2.Kubvisa Inhibitors uye Kugadzira Firimu Yekuita

Mune zvimwe zviitiko, zvicherwa zvinogona kudziviswa nezvimwe zvinhu. Semuenzaniso, kana Sodium Cyanide ikashandiswa semushonga unodzivisa kutenderera kwemvura, inogona kugadzira maion ane zinc - cyanide complex pamusoro pe sphalerite, izvo zvinodzivisa kutenderera kwe sphalerite. Zvisinei, maion ane copper - cyanide complex akasimba kupfuura maion ane zinc - cyanide complex. Kana copper sulfate ikawedzerwa kune sphalerite slurry inodziviswa ne cyanide, cyanide radicals pamusoro pe sphalerite inodonha, uye maion ane free copper anobva aita ne sphalerite kuti agadzire activation film ye copper sulfide, nokudaro achidzorera sphalerite kuti itenderere.

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.
