Njira yayikulu yopindulitsa ya zinc oxide imatulutsa. Pambuyo pakutenthetsa ndi sulufurization, khwangwala amagwiritsidwa ntchito. Mwanjira imeneyi, ore amayamba kukhala okakamizidwa, kenako slurry imatenthedwa mpaka 50-60 ° C ndi sulfurized ndi sodium sulfide. , kenako gwiritsani ntchito kalasi yapamwamba ya xanthate ndi yakuda kuti ibwereke. Ngati pasitedwe ndi kutentha kwa firiji, filimu ya Valcanation singalimbikitsidwe ndipo zotsatira zake zimakhala zosauka. Pa nthawi yotsika-kutentha-kutentha, ndikosavuta kupanga zokongoletsa zodzikongoletsera. M'malo mwake, kutentha kwamphamvu kwambiri kwa filimu, filimu ya Sulfide yopangidwa, kuphatikiza pang'ono kumapangidwa mu slurry, ndipo mwachangu kuthamanga kwa sulurrization. Kukhazikika kwa sodium sulfide pa slurry, ndikofunikiranso chinthu chofunikira kwambiri pamavuto. Sludge, imron oxide ndi manga oxide osilira azitha kudya sodium sulfide ndikuchepetsa mawonekedwe a chidwi, kuti achotsedwe pasadakhale. Choyamba Sulfide kenako njira ya Amine yolongosoka, njirayi ndiyoyenera kutulutsidwa kwa carbonate ya carbonate, silika ndi mchere wina wa oxidid.
Ubwino wa Amine Ottoor ndi kuti mu alkaline sing'anga, umakhala ndi zotsatira zabwino pa quartz ndi alkaline nthaka ya chitsulo. Mchere ulibe mphamvu yofunika kwambiri. Mukamagwiritsa ntchito onyamula ma amine, sodium sulfide osati mphamvu, komanso amayambitsa michere ya zinc. Amines amines amakhala ndi mphamvu yonyamula zizindikiro kwa zinc, makamaka omwe ali ndi ma atomu a kaboni 12-18. Amines oyambira amakhala ofunika kwambiri, pomwe mwayi wopereka majeretary ndi majekiti a tertive ndi ofooka kwambiri. Kutsogolera ndi zinc flowlators Oyang'anira omwe angagawike, oyambitsa, omwe ali ndi ma v smogetors, ocheperako, zopindika komanso zophatikiza zawo potengera zomwe zimachitika munthawi yaufulu.
Pakati pa zoletsa: Zinc sulfate. Mawonekedwe oyera a zinc sulfate ndi oyera akhwangwala, kusungunuka mosavuta m'madzi. Ndi choletsa cha stalelerite. Nthawi zambiri zimakhala ndi mphamvu zokha mu alkaline slorry. Wokwera Ph wa slurry, wamphamvu kwambiri. Zikuwonekeratu. Zirc sulfate imatulutsa zotsatirazi m'madzi: ZNO4 = ZN) 2h 2h20 = ZAN * 2H + ZONSE ) 2 + h2s04 = ZNO4 + 2H2o mu alkaline sing'anga imapereka Hzno2- ndi Zno22-. Adsorption yawo ku michere imawonjezera hydrophilicity ya michere ya mchere. Zn (Oh) 2 Naoh = nahzno2 + h2o zn (o) 2h2o akakhala osauka, ndipo nthawi zambiri amaphatikizidwa ndi cyanamu, sodium sulfide, sulfite kapena thiosulpatete. , sodium carbonate, etc. Kugwiritsa ntchito kosakanikirana kwa zinc sulfate ndi cyanside kumatha kukulitsa zotsatira za stabileite. Chigawo chomwe chimagwiritsidwa ntchito ndi: cyanside: zinc sulfate = 1: 2-5. Pakadali pano, CN- ndi ZN2 + yankhani colloidal zn (CN) 2.
