Ukuhola ne-zinc kuyinto ebalulekile eyisisekelo yokusetshenziswa kokuthuthukiswa komnotho wanamuhla wezenhlalo. Ngokukhula okusheshayo komnotho, isidingo sokuhola ne-zinc siyaqhubeka sikhuphuka, kanye nokuvuselelwa okusebenzayo kokuhola okuyinkimbinkimbi futhi kunzima - izinsizakusebenza zamaminerali ezi-zin-mineral ziye zanda. Kulesi simo, ama-ejenti amaminerali amasha, ikakhulukazi abaqoqi abasebenza ngokuqoqwa okuqinile nokukhetha okuhle, kanye nokuvinjwa kwezimo zemvelo, kanye nama-actishors asebenza kahle, asebenza kahle ekuhlukaniseni okuhlanzekile nokusebenzayo I-Zinc Ores. Okulandelayo kuzokunikeza ukuqonda okuphelele kwezinhlobo zama-reagents ezisetshenziswa ku-lead-zinc ore flotation.
Ukuhola kanye nomqoqi we-zinc flotation
I-Xanthate
Ama-ejenti anjalo afaka i-xanthate, i-Xanthate Esters, njll.
Isibabule ne-nitrogen
Isibonelo, i-Ethyl sulfide inekhono elinamandla lokuqoqa kuneXanthate. Inekhono eliqinile lokuqoqa le-Galena ne-Chalcopyrite, kepha amandla abuthakathaka okuqoqa i-pyrite, ukukhethwa okuhle, isivinini esisheshayo se-flotation, kanye nokusetshenziswa okumbalwa kune-xanthate. Inamandla okuqoqa okuqinile kwezinhlayiya ezihlanganayo zama-sulfide ores, futhi uma isetshenziselwa ukuhlunga ama-ores athile we-Copper-Sulfur, kungafinyelela imiphumela engcono yokuhlunga kune-xanthate.
Umuthi Omnyama
I-Black Powder ngumqoqi ophumelelayo we-sulfide ores, kanye nekhono lawo lokuqoqa abuthakathaka kunalokho kwe-xanthate. Umkhiqizo we-solubity we-dihydrocarbyl dithiophosphate we-ion efanayo yensimbi mkhulu kunalokho kwe-xanthate ye-ion ehambisanayo. Umuthi omnyama unezinto ezigwebu. Ama-powders ajwayelekile asetshenziswa embonini afaka: Cha. 25 Black powder, i-Butylammonium Black Powder, Amine Powder Powder, kanye ne-Naphthenic Black Powder. Phakathi kwazo, i-Bubylammonium Black Powder (Dibutyl Ammonium Dithiophosphate) iyimpuphu emhlophe, incibilika kalula emanzini, iphenduka ibe mnyama ngemuva kokuhlehlisa, futhi inezakhiwo ezithile ze-fooming. Ilungele ukugcwaliswa kwe-arfide ores enjengethusi, ukuhola, i-zinc, kanye ne-nickel. . E-alkalily alkaliry slurry, amandla okuqoqa ama-pyrite ne-Pyrrhotite abuthakathaka, kepha amandla okuqoqa weGalena aqinile.
Umlawuli we-Holid Flotation
Ama-aguqukayo angahlukaniswa ngama-inhibitors, ama-activators, ama-activaters e-PH PH, ukuhlakazeka kwe-slime, ama-coabulants kanye ne-flocculants ngokuya ngeqhaza labo kwinqubo yabo. Ama-aguqukayo afaka amakhompiyutha ahlukahlukene we-inorganic (afana nosawoti, izisekelo kanye nama-acid) kanye nezinhlanganisela ze-organic. Umenzeli ofanayo uvame ukudlala izindima ezahlukahlukene ngaphansi kwezimo ezahlukahlukene ze-flotation.
I-Cyanide (NACN, KCN)
I-Cyanide iyi-inhibitor esebenzayo ngesikhathi sokuhola ne-zinc ukuhlela. I-Cyanide ikakhulukazi i-sodium cyanide ne-potassium cyanide, ne-calcium cyanide nayo iyasetshenziswa. I-Cyanide ngusawoti okhishwe isisekelo esinamandla ne-acid elibuthakathaka. I-Hydrolyzes in the slurry ukukhiqiza i-HCN ne-CNˉ
KCN = K⁺ + CNˉ CN + H₂O = HCN⁺ + Ohˉ
Ukusuka ku-equation elwela ngangenhla, kungabonakala ukuthi epulpini ye-alkaline, ukugcwala kwe-CNˉ kuyanda, okuzuzisa ukuvinjwa. Uma i-PH yehlisiwe, kwakhiwa i-HCN (HCDOCYANIC Acid) futhi umphumela wokuvimbela uncishisiwe. Ngakho-ke, lapho usebenzisa iChanide, imvelo ye-alkali ye-alkali kumele igcinwe. I-Cyanide ingumenzeli onobuthi kakhulu, kanye nocwaningo lwama-cyanide-free noma ama-cyanide - ama-inhibitors aqhubeka iminyaka eminingi.
I-Zinc Sulfate
Umkhiqizo omsulwa we-zinc sulfate u-crystal omhlophe, unyibilika kalula emanzini, futhi uyisixhumi se-sphalerite. Imvamisa inomphumela ovimbayo kuphela e-Alkaline Slurry. I-PH ephakeme i-PH ye-Slurry, umphumela osobala ngokwengeziwe. I-Zinc Sulfate ikhiqiza ukusabela okulandelayo emanzini:
Znso₄ = zn²⁺ + so₄
Zn²⁺ + 2h₂o = ZN (oh) ₂ + 2h⁺zn (oh) ₂ iyingxenye ye-Amphoteric ehlakazekile nge-acid ukwenza usawoti
Zn (oh) ₂ + H₂so₄ = znso₄ + 2h₂o
E-Alkaline Medium, Hzno₂ˉ noZno₂²ˉ batholakala. Ama-adsorption abo amaminerali athuthukisa i-hydrophicity yezindawo ezinamaminerali.
Zn (oh) ₂ + Naoh = nahzno₂ + h₂o
I-ZN (oh) ₂ + 2naoh = naɪzno₂ + 2h₂o
Lapho i-zinc sulfate isetshenziswa yedwa, umphumela wokuvimbela umpofu ampofu. Imvamisa isetshenziswa ngokuhlanganiswa ne-cyanide, i-sodium sulfide, i-sulfite noma i-thiosulfate, i-soosulfate, i-sodium carbonate, njll. Ukusetshenziswa okuhlanganisiwe kwe-zinc sulfate ne-cyanide kungathuthukisa umphumela wokuvinjwa ku-sphalerite. Isilinganiso esisetshenziswa njalo yile: Cyanide: Zinc sulfate = 1: 2-5. Ngalesi sikhathi, ifomu le-CNˉ ne-ZN²⁺ leColloidal Zn (CN) ₂ liqonde.
