Mgodi-zinki wanga, kusankha bwanji?

Mwa mitundu yambiri yamchere, miyala ya lead-zinc ndi yovuta kusankha.Nthawi zambiri, lead-zinc ore imakhala ndi ore osauka kwambiri kuposa ore olemera ndipo zigawo zomwe zimagwirizana ndizovuta kwambiri.Chifukwa chake, momwe mungasiyanitsire bwino lead ndi zinc ores ndi nkhani yofunika kwambiri pamakampani opanga mchere.Pakali pano, mchere wotsogola ndi zinki zomwe zimagwiritsidwa ntchito m'mafakitale ndi galena ndi sphalerite, komanso zimaphatikizapo smithsonite, cerussite, ndi zina zotero. zinc oxide ore, ndi ore osakanikirana a lead-zinc.Pansipa tisanthula mwatsatanetsatane njira yolekanitsa ya lead-zinc ore kutengera kuchuluka kwa oxidation ya lead-zinc ore.

Njira yolekanitsa ya lead-zinc sulfide ore
Pakati pa miyala ya lead-zinc sulfide ore ndi lead-zinc oxide ore, miyala ya lead-zinc sulfide ndiyosavuta kusankha.Lead-zinc sulfide ore nthawi zambiri imakhala ndi galena, sphalerite, pyrite, ndi chalcopyrite.Mchere waukulu wa gangue umaphatikizapo calcite, quartz, dolomite, mica, chlorite, ndi zina zotero. Choncho, malinga ndi mgwirizano wophatikizidwa wa mchere wothandiza monga kutsogolera ndi nthaka, siteji yogaya imatha kusankha njira yopera imodzi kapena njira zambiri zopera. .

Njira yopera ya gawo limodzi nthawi zambiri imagwiritsidwa ntchito popanga miyala ya lead-zinc sulfide yokhala ndi makulidwe ambewu yokulirapo kapena maubale osavuta a symbiotic;

Mipikisano siteji akupera ndondomeko njira lead-zinki sulfide miyala ndi zovuta intercalation maubale kapena bwino tinthu kukula.

Pazitsulo za lead-zinc sulfide, kugayanso michira kapena kugayanso kwambiri kumagwiritsidwa ntchito nthawi zambiri, ndipo njira yopangira zitsulo zapakati sigwiritsidwa ntchito kawirikawiri.Mu gawo lopatukana, lead-zinc sulfide ore nthawi zambiri imatenga njira yoyandama.Njira zoyandama zomwe zimagwiritsidwa ntchito pano zikuphatikizapo: ndondomeko yoyandama patsogolo, njira yosakanikirana yoyandama, ndi zina zotero. Kuphatikiza apo, kutengera njira yachindunji yoyandama, njira zofanana zoyandama, njira zowongoka komanso zolekanitsa bwino, njira zoyendera nthambi za nthambi, etc. omwe amasankhidwa makamaka malinga ndi kukula kwawo kosiyanasiyana ndi maubwenzi ophatikizidwa.

Pakati pawo, njira yoyandama yofanana ili ndi zabwino zina pakuyandama kwa ore-zinc ore chifukwa imaphatikiza kuyandama kwa ore ovuta kuwalekanitsa ndi ores osavuta kuwalekanitsa ndikuwononga mankhwala ocheperako, makamaka ngati pali zosavuta. -kulekanitsa miyala mu miyala.Pakakhala mitundu iwiri ya mchere wa lead ndi zinki womwe umayandama komanso wovuta kuyandama, njira yoyandama ndiyo yabwino kwambiri.

Njira yosiyanitsira zinc oxide ore
Chifukwa chomwe lead-zinc oxide ore ndizovuta kusankha kuposa lead-zinc sulfide ore makamaka chifukwa cha zigawo zake zovuta, zigawo zosakhazikika, kukula kwa tinthu tating'onoting'ono, komanso kuyandama kofanana kwa mchere wa lead-zinc oxide ndi mchere wa gangue. ndi mineral slime., chifukwa cha zotsatira zoipa za mchere wosungunuka.

Pakati pa lead-zinc oxide ores, omwe ali ndi phindu la mafakitale akuphatikizapo cerusite (PbCO3), lead vitriol (PbSO4), smithsonite (ZnCO3), hemimorphite (Zn4(H2O)[Si2O7](OH)2), etc. Pakati pawo, cerusite , lead vitriol ndi molybdenum lead ore ndizosavuta kupanga sulfide.Sulfiding agents monga sodium sulfide, calcium sulfide ndi sodium hydrosulfide angagwiritsidwe ntchito pochiza sulfure.Komabe, lead vitriol imafuna nthawi yayitali yolumikizana panthawi yavulcanization.The vulcanizing agent Mlingo nawonso ndi waukulu.Komabe, arsenite, chromite, chromite, ndi zina zotero zimakhala zovuta ku sulfide ndipo zimakhala zovuta kuyandama.Kuchuluka kwa mchere wothandiza kudzatayika panthawi yolekanitsa.Kwa lead-zinc oxide ores, njira yoyambira yoyambira nthawi zambiri imasankhidwa ngati njira yayikulu yolekanitsira, ndipo ma desliming amachitidwa asanayandame kuti apititse patsogolo zizindikiro zoyandama komanso kuchuluka kwa mankhwala.Pankhani ya kusankha kwa wothandizira, xanthate wautali wautali ndi wosonkhanitsa wamba komanso wogwira ntchito.Malingana ndi zotsatira zosiyana za mayesero, zikhoza kusinthidwanso ndi Zhongoctyl xanthate kapena No. 25 mankhwala akuda.Zotolera zamafuta monga oleic acid ndi sopo wa parafini wokhala ndi okosijeni sasankha bwino ndipo amangoyenera kutsogolere apamwamba kwambiri okhala ndi silicates ngati gangue yayikulu.
