Kutsogolera ndi zinc ndi kiyi zopangira zopangira zopangira zachuma chamakono. Ndi kukula kwachuma mwachangu, kufunikira kwa kutsogolera ndi zinc akupitiliza kuwonjezeka, komanso kubwezeretsanso koyenera kwa otsogolera otsogola komanso ovuta kusankha ndi zinziri wakhala kofunika kwambiri. Munthawiyi, othandizira a mineral atsopano, makamaka otobala ndi kusankhidwa bwino zinc Ores. Zotsatirazi zikuthandizani kuti mumvetsetse bwino mitundu ya mitundu ya ma reagents omwe amagwiritsidwa ntchito poyambira.
Kutsogolera ndi kutola kwa zinc flootation
xanthate
Otsatirawa amaphatikizapo XATHHATE, XATHHATE ESTER, etc.
Sulufule ndi nayitrogeni
Mwachitsanzo, ethyl sulfide ali ndi mphamvu yopereka mphamvu kuposa xantha. Imakhala ndi luso lopereka la Galena ndi Chalcopyyrrite, koma kulephera kutolera zolemba zabwino, kuthamanga mwachangu, komanso kugwiritsa ntchito ochepa kuposa xanthate. Ili ndi mphamvu yonyamula mphamvu ya tinthu tating'onoting'ono, ndipo zikagwiritsidwa ntchito posankha ma ores otsogola, zimatha kukonza zabwino kuposa xanthate.
Mankhwala Akuda
Ufa wakuda ndi wotolera wa sulfide ores, ndipo luso lake lotolera limakhala lofooka kuposa la xanthate. Katundu wa dithiculocarbyl dithiososphate wa ion yomweyo ion ndi yayikulu kuposa ya xanthate ya ion. Mankhwala akuda ali ndi malo omenyera. Zofananira ndi ufa wakuda m'mafakitale zimaphatikizapo: No. 25 ufa wakuda, koma ufa wakuda, amine wakuda ufa, ndi ufa wakuda. Pakati pawo, atylamomoni akuda (Dibutyl Amonium Dithiososphate) ndi ufa woyera, umatembenuka wakuda pambuyo pofufuza, ndipo ali ndi malo ena owonda. Ndioyenera kubwereka kwa sulfation ya ma ores monga mkuwa, kutsogolera, zinc, ndi nickel. . Pofooka alkaline slurry, kuthekera kwa PRYRITE ndi PRYHthot ndi ofooka, koma kuthekera kwa Galena ndi wamphamvu.
Kutsogolera ndi zinc flootation Wothandizira
Adjus amatha kugawidwa mu inhabitor, oyendetsa mafayilo a media, slide ochepa, coagulants ndi mabotolo malinga ndi udindo wawo. Maulendo akuphatikizira mitundu ingapo yopangira (monga mchere, zokumba ndi asidi) ndi zopangira zachilengedwe. Wothandizira yemweyo nthawi zambiri amasewera maudindo osiyanasiyana mosiyanasiyana.
Cyanide (Nacn, KCN)
Cyanside ndi chovomerezeka choletsa pakutsogolera ndi kusanja. CYanide amakhala makamaka sodium cyanja ndi potaziyamu cyanjalide, ndipo calcium cyanside amagwiritsidwanso ntchito. Cyanjade ndi mchere wopangidwa ndi maziko olimba komanso ofooka acid. Zimachita ma hydrolyzos pa slurry kuti mupange HCN ndi CNˉ
KCN = K⁺ + CNˉ CN + h₂o = hcn⁺ + ohˉ
Kuchokera pa equation yapamwambayo pamwambapa, imatha kuwoneka kuti mu alkaline zamkati, kuchuluka kwa CNˉ kumawonjezeka, komwe kumakhala kopindulitsa. Ngati PH imatsitsidwa, hcn (hydrocyonic acid) imapangidwa ndipo zotsatira za choletsa zimachepetsedwa. Chifukwa chake, mukamagwiritsa ntchito cyanide, mtundu wa kusalala uyenera kusungidwa. Cyanside ndi wothandizila kwambiri, ndipo amafufuza za zotupa za cyanide kapena cyanade, zakhala zikupitilira zaka zambiri.
zinc sulfate
Chopangidwa ndi choyera cha zinc sulfate ndi choyera choyera, kusungunuka mosavuta m'madzi, ndipo ndi choletsa cha stabilerate. Nthawi zambiri zimakhala ndi mphamvu zokha mu alkaline slorry. Zowonjezera Ph wa slurry, zowonekeratu zowonjezera. Zirc sulfate imatulutsa zotsatirazi m'madzi:
ZNO₄ = ZNZO +
Zn² "zn (oh) ₂ + 2h⁺zn (oh) ₂
ZN) ₂ + H₂SO₄ = ZNSO + 2H₂O
Mu alkaline sing'anga, Hzno₂ˉ ndi Zno₂, amapezeka. Adsorption yawo ku michere imawonjezera hydrophilicity ya michere ya mchere.
ZN (oh) ₂ + Naoh = nahzno₂ + h₂o
Zn (Oh) ₂ + 2naoh = Na₂zno₂ + 2h₂o
Pamene zinc sulfate imagwiritsidwa ntchito yokha, zotsatira za choletsa sizabwino. Nthawi zambiri zimagwiritsidwa ntchito limodzi ndi cyanide, sodium sulfide, sulfite kapena thisulpate, e sotimaum carphate ndi cyanside amatha kukulitsa zotsatira za stabileite. Chigawo chomwe chimagwiritsidwa ntchito ndi: cyanside: zinc sulfate = 1: 2-5. Pakadali pano, CNˉ ndi ZNZO PANGANI ZN (CN) ₂.
