Lead-zinc mine, ungasarudza sei?

Lead-zinc mine, ungasarudza sei?

Pakati pemhando dzakawanda dzemaminerari, lead-zinc ore isimbi yakaoma kusarudza.Kazhinji kutaura, lead-zinc ore ine ore yakashata kupfuura ore akapfuma uye izvo zvinobatanidzwa zvakanyanya kuoma.Naizvozvo, nzira yekunyatsoparadzanisa lead uye zinc ores zvakare inyaya yakakosha muindasitiri yekugadzira zvicherwa.Parizvino, mutungamiri uye zinc zvicherwa zviripo zvekushandiswa kwemaindasitiri zvakanyanya galena uye sphalerite, uye zvakare zvinosanganisira smithsonite, cerussite, etc. Maererano nedhigirii ye oxidation, lead-zinc minerals inogona kukamurwa kuita lead-zinc sulfide ore, lead- zinc oxide ore, uye yakasanganiswa lead-zinc ore.Pazasi isu tichanyatso ongorora nzira yekuparadzanisa ye lead-zinc ore zvichibva pane oxidation degree ye lead-zinc ore.

Lead-zinc sulfide ore separation process
Pakati pechicherwa chelead-zinc sulfide uye lead-zinc oxide ore, lead-zinc sulfide ore iri nyore kuronga.Lead-zinc sulfide ore kazhinji ine galena, sphalerite, pyrite, uye chalcopyrite.Iyo huru gangue minerals inosanganisira calcite, quartz, dolomite, mica, chlorite, etc. Naizvozvo, maererano nehukama hwakamisikidzwa hwemaminerari anobatsira akadai semutobvu uye zinc, danho rekukuya rinogona kusarudza danho rimwe chete rekukuya kana nhanho yakawanda yekukuya. .

Iyo imwe-nhanho yekukuya inowanzoshandiswa kugadzira lead-zinc sulfide ores ine coarser saizi yezviyo kana nyore symbiotic hukama;

Iyo yakawanda-nhanho yekukuya maitiro inogadzira lead-zinc sulfide ores ine yakaoma intercalation hukama kana akatsetseka particle size.

Kune lead-zinc sulfide ores, kugaya regrinding kana coarse concentrate regrinding kunowanzoshandiswa, uye yepakati ore regrilling process haiwanzo shandiswa.Muchikamu chekuparadzanisa, lead-zinc sulfide ore inowanzotora flotation process.Iyo parizvino inoshandiswa flotation process inosanganisira: yekutanga flotation process, yakasanganiswa flotation process, etc. Mukuwedzera, zvichibva pane yakajairwa yakananga flotation process, yakaenzana flotation process, coarse uye yakanaka kupatsanura maitiro, branched series flow process, etc. izvo zvinonyanya kusarudzwa zvichienderana nehukuru hwavo hwakasiyana uye hukama hwakaiswa.

Pakati pavo, iyo yakaenzana flotation process ine zvimwe zvakanakira mukuyangarara kwelead-zinc ore nekuti inosanganisa nzira yekuyangarara yakaoma-ku-kupatsanura ores uye nyore-kuparadzanisa ores uye inoshandisa mashoma makemikari, kunyanya kana paine nyore. -kuparadzanisa ore mumatombo.Kana paine marudzi maviri emutobvu uye zinc zvicherwa zviri kuyangarara uye zvakaoma kukuyangarara, nzira yekuyangarara isarudzo yakakodzera.

Lead zinc oxide ore kupatsanurwa maitiro
Chikonzero nei lead-zinc oxide ore ichinyanya kunetsa kusarudza kupfuura lead-zinc sulfide ore inonyanya kukonzerwa neyakaomesesa zvinhu zvemukati, isina kugadzikana inosanganisirwa zvikamu, yakanaka yakamisikidzwa particle size, uye yakafanana floatability yelead-zinc oxide minerals uye gangue minerals. uye mineral slime., inokonzerwa nemigumisiro yakaipa yemunyu unonyunguduka.

Pakati pe-lead-zinc oxide ores, avo vane kukosha kwemaindasitiri vanosanganisira cerusite (PbCO3), lead vitriol (PbSO4), smithsonite (ZnCO3), hemimorphite (Zn4 (H2O) [Si2O7] (OH) 2), nezvimwewo Pakati pavo, cerusite , lead vitriol uye molybdenum lead ore zviri nyore kuita sulfide.Sulfiding agents akadai sodium sulfide, calcium sulfide uye sodium hydrosulfide inogona kushandiswa kurapa sulfurization.Nekudaro, lead vitriol inoda nguva yakati rebei yekuonana panguva yekuita vulcanization.Iyo vulcanizing agent Iyo dosage zvakare yakakura.Zvisinei, arsenite, chromite, chromite, nezvimwewo zvakaoma sulfide uye hazvina kutenderera zvakanaka.Nhamba yakawanda yemaminerari anobatsira icharasika panguva yekuparadzanisa.Kune lead-zinc oxide ores, iyo yekutanga flotation process inosarudzwa seyakanyanya kupatsanura maitiro, uye desliming mashandiro anoitwa pamberi pe flotation kunatsiridza flotation zviratidzo uye dosage yemakemikari.Panyaya yekusarudzwa kweagent, refu-chain xanthate inowanzoitika uye inoshanda muunganidzi.Maererano nemigumisiro yakasiyana-siyana yekuedza, inogonawo kuchinjwa neZhongoctyl xanthate kana No. 25 mishonga yakasviba.Fatty acid vaunganidzi vakaita seoleic acid uye oxidized parafini sipo vane kusarudzika kwakashata uye vanokodzera chete kune yakakwirira-giredhi lead ores ine silicates seiyo huru gangue.
