Ungazuza kanjani i-zinc onide ore?

Inqubo eyinhloko yeZinzuzo ye-zinc oxide ingukufunga. Ngemuva kokushisa nokuhlukunyezwa, kusetshenziswa i-Xanthate flotation. Ngale ndlela, i-ore iqale yancishiswa, bese kubambeka kufudunyezwa ku-50-60 ° C kanye ne-sulfurized nge-sodium sulfide. , bese usebenzisa i-xanthate ephezulu ne-powder emnyama yokugcwala. Uma i-Vulcan emazingeni okushisa asekamelweni, ifilimu yokuvuselela i-vulcanization ngeke iqine futhi umphumela wokufafazwa uzoba mpofu. Ngesikhathi sokushisa amazinga okushisa, kulula ukwenza amafomu e-colloidal. Ngokuphambene nalokho, kuphakama amazinga okushisa we-vulcanization, amafilimu ashubile asungula, amachashazi amancane akhiwe eSlurry, futhi ngokushesha kwejubane lokuphamba. Ukuhlushwa kwe-sodium sulfide ku-slurry, futhi kuyinqubo ebaluleke kakhulu yenqubo ngesikhathi sokuvuselela. I-Sludge, i-iron oxide ne-manganese oxide ku-slurry izodla i-sodium sulfide futhi inciphise ikhwalithi yokugxila, ngakho-ke kufanele isuswe kusengaphambili. I-sulfide yokuqala bese uyindlela ye-anine flotation, le ndlela ilungele ukugcwala kwe-zinc carbonance, izimbumbulu kanye namanye amaminerali ahlanganisiwe.

Inzuzo ye-Amine Collector ukuthi e-Alkaline Medium, inomphumela omuhle ku-quartz kanye ne-alkali yomhlaba wensimbi carbon. Usawoti awunawo umphumela wokuqoqa obalulekile. Lapho usebenzisa abaqoqi be-Amine, i-sodium sulfide esele ayigcini ngokungenamphumela wokuvimbela, kepha futhi isebenze amaminerali e-zinc onide. Ama-Amines aphambili anomphumela oqinile wokuqoqa ku-zinc oxide, ikakhulukazi lawo aqukethe ama-athomu wekhabhoni ayi-12-18. Ama-amorines abalulekile abaluleke kakhulu, ngenkathi amakhono wokuqoqa ama-anine asekondari aphezulu abuthakathaka kakhulu. Ukuhamba kwama-relulators atholakalayo kanye nama-zinc flotation aguqulwa kungahlukaniswa ngama-inhibitors, ama-activators, ama-medium PH alawulayo, ama-displants asabekayo, ama-coabulants kanye nama-reagulants ngokwemisebenzi yawo.

Phakathi kwama-inhibitors: I-Zinc Sulfate. Uhlobo oluhlanzekile lwe-zinc sulfate luyi-crystal emhlophe, incibilika kalula emanzini. Kuyinto inhibitor of sphalerite. Imvamisa inomphumela ovimbayo kuphela e-Alkaline Slurry. I-PH ephakeme i-PH ye-Slurry, inamandla amandla ayo ayi-inhibitory. Kuba sobala ngokwengeziwe. I-Zinc Sulfate ikhiqiza ukusabela okulandelayo emanzini: ZNSO4 = ZN2 ++ ) 2 + H2S04 = ZNSO4 + 2h2o e-Alkaline Medium inika i-Hzno2- ne-ZNO22-. Ama-adsorption abo amaminerali athuthukisa i-hydrophicity yezindawo ezinamaminerali. Zn (oh) 2 + Naoh = Nahzno2 + H2O ZN (H2O ZN (OHNOOH = NA2ZNO2 + 2h2o Lapho i-zinc sulfate isetshenziswa yedwa, futhi kuvame ukuhlanganiswa ne-cyanide, i-sulfite noma thiosulfate. , i-sodium carbonate, njll. Isetshenziswe ndawonye. Ukusetshenziswa okuhlangene kwe-zinc sulfate ne-cyanide kungathuthukisa umphumela wokuvinjwa ku-sphalerite. Isilinganiso esisetshenziswa njalo yile: Cyanide: Zinc sulfate = 1: 2-5. Ngalesi sikhathi, i-CN- ne-ZN2 + iFomu Colloidal Zn (CN) 2 i-Precipitate.
