Isishwankathelo sokukhokela kunye ne-winc mineral menders

I-1. Khokela kunye ne-zinc qokecy qokector

Abaqokeleli obuqhelekileyo abasetyenziswa ngokuqhelekileyo ukuze i-iresi ye-zinc iquka:

1. IXATHATE. Olu hlobo lwe-arhente lubandakanya i-XATHATE, XSEHATE ESTER, njl. Njl.

2. I-Sulfure Nitrogen, njenge-Emey Sulfur Nitrogen, inamandla okuqokelelwa komelele ngakumbi kuneXanthate. Inamandla okuqokelelwa kwe-galena kunye neCilcoprite, kodwa amandla obuthathaka ukuqokelela iPyrite, ukukhetha okuhle, isantya sokudakumba esikhawulezayo, kunye nokusetyenziswa okumbalwa kuneXanthate. Inomyinge wokuqokelelwa kwengqokelela yamasuntswana ahlanganisiweyo ye-ore ye-sulfide. Xa isetyenziselwa ukuhlelwa-ukukhokela i-oresper-i-isure, inokufumana iziphumo zokuhlekisa okungcono kuneXanthate.

3.Black iyeza

Umgubo omnyama ngumqokeleli ofanelekileyo wokuqokelelwa i-ores ores, kunye nobuchule bayo bokuqokelelwa bubuthathaka kunaleyo yeXanthate. Imveliso ye-solidaity ye-dihydrocarby i-rithiophosphate yentsimbi enye inkulu kune-xenthate ye-Ion ehambelana ne-ion. Amayeza amnyama anepropathi.

I-powders eziqhelekileyo ezisetyenziswayo kumzi-mveliso zibandakanya: Hayi. Umgubo omnyama, i-blamlammonium emnyama, umgubo oMnyama oMnyama, kunye nomgubo omnyama we-naphthether, kunye nomgubo omnyama. Phakathi kwazo, i-byylammoium emnyama yomgubo (i-hamonium ye-diimiiophosphate) ngumgubo omhlophe, inyibilikiswe ngokulula emanzini, ijika imnyama emva kokuphelisa iipropathi ezizezona, kwaye zinepropathi ethile. Ilungele ukuqhwatywa kwe-orest ye-sulfide enje ngobhedu, ukukhokela, i-zinc, kunye ne-nickel. . Kwisilayidi se-alkaline, ubuchule bokuqokelela kwePyrite kunye nePyrrhotite buthathaka, kodwa amandla okuqokelela kweGalena yomelele.

I-2. I-Collefic kunye ne-zenic flotation yomlawuli

Ngokwendima yabo kwinkqubo yokufuduselwa, i-adjusisters inokwahlulwa ibe:

Abavumisi beqokelela imilinganiselo eyahlukeneyo ye-Inorganic (ezinjengeetyus, iziseko kunye ne-acids) kunye nee-organic. Iarhente efanayo idla ngokudlala indima eyahlukeneyo phantsi kweemeko ezahlukeneyo zeflota.

I-inhibitors:

I-1. I-Lime Lime (i-Cao) inolwazi lwamanzi olomeleleyo kwaye iphinde isebenze ngamanzi ukwenza i-CADED CA TA (O) 2. Kunzima ukunyibilikisa emanzini kwaye yi-alkali eyomeleleyo. Ukuphendula xa kongezwa kwiflory slicry ngolu hlobo lulandelayo:

I-Cao + h2o = ca (oh) 2

I-CA (oh) 2 = I-Caoh ++ Owu-

Caoh + = ca2 ++ 0

I-Lime ihlala isetyenziselwa ukwandisa ixabiso le-pH ye-slickry kunye ne-inhibit yentsimbi yentsimbi. Kwisilivere yobhedu, khokela, kunye ne-ininc, zihlala zihamba kunye ne-Iron Sulfide Ores (Pyrite, Pyrrhotite, i-Pyroarnite, njengePyroarchrite). Ukwenzela ukuba ube bhetele ubhedu, khokela, kunye neeminerals ze-zinc, i-lime ihlala yongezwa kwi-in the the the the the tilfide yentsimbi.

I-2. ICynide (NCN, KCN)

I-cynide yi-inhibitor esebenzayo ngexesha lokukhokela kunye nokuhlelwa kwe-zinc. I-cynide ikakhulu i-sodium ye-sodium cynide kunye ne-potassium cynide, kwaye i-calcium isetyenziswa.

I-cynide ityiwa ityuwa eveliswe sisiseko esomeleleyo kunye ne-acid ebuthathaka. I-hydrolyzed kwi-slingry yokwenza i-hcn kunye ne-cn-

Kcn = k ++ cn-

I-CN + h2o = hcn ++ o-

Ingabonwa kwi-equation elungelelanisiweyo ngentla koko kwi-Alkaline Slarry, ukuhanjiswa kwe-CN- Undiso, oluyingenelo kulo. Ukuba i-pH ithotyelwe, i-HCN (HYDDOCCINCIC Acid) yenziwa kwaye isiphumo sokuthintela siyancitshiswa. Ke ngoko, xa usebenzisa i-cyAnide, imeko ye-alkali ye-alkali yesilayidi kufuneka igcinwe.

3.Ziyi

Imveliso ecocekileyo ye-zulc supelfate i-crystal emhlophe, inyibilikiswe ngokulula emanzini, kwaye i-inhibite ye-schalerite. Ihlala inefuthe kuphela kwi-alkaline ye-alkaline. I-PH ye-PH ye-slickry, eyona nto icacileyo yokungazithembi. I-Zinc swelfate ivelisa le ndlela ilandelayo emanzini:

ZNSO4 = ZN2 ++ Is42-

ZN2 ++ 2h20 = ZN (O) 2 + 2h +

I-ZN (O) 2 yindawo ye-ampPhoteric equbene kwi-acid ukwenza ityiwa.

ZN (O) 2 + H2S04 = ZNON4 + 2O

Kwi-alkaline ephakathi, i-HZNo2- kunye ne-Zno22- ifunyenwe. I-adsorption yabo kwiminatha iphucula i-hydrophicicicicicicicicicicicicicicicicity eziphezulu.

ZN (oh) 2 + u-nah = nahzno2 + h2o

Zn (oh) 2 + 2NOOH = na2 + 2o

Xa i-zinc sulfate isetyenziswa yedwa, isiphumo sokuthintela kungamahlwempu. Ihlala isetyenziswa ngokudibeneyo neCynide, iSodium sulfide, i-Sulfite okanye i-thioulfleate, i-sodium ye-sodium, njl.

Ukusetyenziswa okuhlanganisiweyo ze-zulc i-chinc kunye ne-cynide kunokuphucula isiphumo sokuthintela i-schalerite. Umyinge oqhelekileyo osetyenzisiweyo: cynide: i-zulc sulfate = 1: 2-5. Ngeli xesha, i-CN- kunye ZN2 + iFobloidal ZN
