Isifinyezo Sokuhola kanye nama-Zinc Mineral Agents

1. Ukuhola kanye ne-Zinc Flotation Collector

Abaqoqi abavame ukusetshenziswa kwe-Lead-Zinc Ores bafaka:

1. Xanthate. Lolu hlobo lwe-ejenti lufaka i-xanthate, i-xanthate ester, njll.

2 Inekhono eliqinile lokuqoqa le-Galena ne-Chalcopyrite, kepha amandla abuthakathaka okuqoqa i-pyrite, ukukhethwa okuhle, isivinini esisheshayo se-flotation, kanye nokusetshenziswa okumbalwa kune-xanthate. Inesilinganiso sokuqoqa esiqinile sezinhlayiya zama-sulfide ore. Uma isetshenziselwa ukuhlunga ama-ores athile we-Copper-Lead-Sulfur, ingathola imiphumela engcono yokuhlela kune-Xanthate.

Umuthi we-3.Black

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.

2. Ukuhola kanye noMlawuli we-Zinc Flotation

Ngokweqhaza labo enqubweni yokugcwala, ama-adverers angahlukaniswa: ama-inhibitors, ama-acticeators, ukuguqulwa okuphakathi kwe-PH, ukuhlakazeka kwe-slime, ama-coabulents kanye nama-reagulants.

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-inhibitors:

1. I-Lime Lime (CAO) inomunwe oqinile wamanzi futhi iphendule ngamanzi ukuze kwakhiwe i-hydrate lime ca (oh) 2. Kunzima ukuncibilikisa emanzini futhi kuyinto eqinile ye-alkali. Ukusabela lapho kungezwe ku-slurry flotation kungokulandelayo:

Cao + h2o = ca (oh) 2

Ca (oh) 2 = caoh ++ oh-

Caoh + = I-CA2 ++ 0h-

I-Lime ivame ukusetshenziselwa ukwandisa inani le-PH le-Slurry futhi livimbela amaminerali we-Iron Sulfide. E-sulfide yethusi, ukuhola, kanye ne-zinc ores, zivame ukuhambisana ne-iron sulfide ores (i-pyrrhotic, i-parcasite, i-marcasite, ne-arsenopyrite). Ukuze kufakwe ngcono ithusi, ukuhola, kanye namaminerali e-zinc, kuvame ukwengezwa ukuvimbela amaminerali we-iron sulfide.

2. 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-hydrolyzed in the slurry ukukhiqiza i-HCN ne-CN-

Kcn = k ++ cn-

Cn + h2o = hcn ++ oh-

Kungabonakala kusuka ku-equation ekhawulelwe ngenhla ukuthi e-Alkaline Slurry, ukugcwala kwe-CN- 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.

3.Zin 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 ++ SO442-

I-ZN2 ++ 2h20 = ZN (O) 2 + 2H +

I-ZN (OH) 2 iyingxenye ye-Amphoteric ehlakazayo nge-acid ukwenza usawoti.

Zn (oh) 2 + h2s04 = znso4 + 2h2o

E-Alkaline Medium, Hzno2- naseZno22- ziyatholakala. Ama-adsorption abo amaminerali athuthukisa i-hydrophicity yezindawo ezinamaminerali.

Zn (oh) 2 + Naoh = nahzno2 + h2o

I-ZN (oh) 2 + 2naoh = NA2ZNO2 + 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-sodium carbonate, njll.

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.
