Ukukhokela kwaye i-zinc zizinto eziphambili eziluhlaza zolwaphulo-mthetho kuphuhliso loqoqosho lwangoku. Ngokukhula ngokukhawuleza kwezoqoqosho, ibango lokukhokela kwaye i-zinc iqhubeka inyusa, kwaye isebenze ngokutsha kwezinto ezikhoyo kwaye inobunzima-ukukhetha-ukukhetha i-Commass kwaye i-zinc yezixhobo zeZimbile kwaye iZinc ziye zakhawuleza. Kule meko, iiarhente ezintsha zezimbiwa, ngakumbi abaqokeleli okusebenza ngokuqinileyo kunye nokukhetha okuhle, kunye nexabiso eliphantsi, kunye nezinto ezinobuchule, zibaluleke kakhulu kwi-Cound- I-ininc i ores. Oku kulandelayo kuya kukunika ukuqonda okubanzi kweentlobo ze-regentnts esetyenziswe kwi-Collection-ye-chinc ore.
Khokelela kunye ne-zinc qokecy qokeleli
Xanthate
Iiarhente ezinjalo zibandakanya i-chanthate, i-xenthate Esters, njl.
I-Sulfuur kunye ne-nitrogen
Umzekelo, i-seryol sulfeide 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. Inamandla omeleleyo ahlangane amasuntswana ahlanganisiweyo ze-ores, kwaye xa isetyenziselwa ukuhlela i-ores-sulper-i-ores, inokufezekisa iziphumo ezingcono kakhulu kuneXanthate.
Amayeza amnyama
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.
INDAWO YOKUKHUSELEKILEYO NOKUVIWA KWE-ZINAT UMGAQO-NKQUBO
Abathengisi banokwahlulwa-hlulwa bahlulwe baba yi-inhibitors, abathengisi, abathengisi bemidiya, abasasazi beemidimi, abakhweli kunye nepeyili ngokwendima yabo kwinkqubo yenkqubo. 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-cyanide (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-hydrolyzes kwi-slickry yokwenza i-hcn kunye ne-cnˉ
Kcn = k⁺ + cn + h₂o = hcn⁺ + ohˉ
Ukusuka kule mpazamo ilunge ngasentla, inokubonwa ukuba kwi-alkaline Pulp, uxinzelelo lwe-CNˉ, oluyingenelo kwi-infinition. 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. I-cynide yiarhente enetyhefu kakhulu, kunye nophando nge-cyanide-free-free-encinci yokuthintela i-inhibitors iye yaqhubeka iminyaka emininzi.
I-Zinc sulfate
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:
Znsso₄ = Zn²⁺ + So₄
Zn²⁺ + 2h₂o = ZN (O) ₂ + 2h⁺zn (O)
Zn (oh) ₂ + h₂so₄ = Zons + 2h₂o
Kwi-alkaline ephakathi, i-HZNo₂ˉ kunye ZNo₂²ˉ zifunyenwe. I-adsorption yabo kwiminatha iphucula i-hydrophicicicicicicicicicicicicicicicicity eziphezulu.
Zn (O) ₂ + Nahh = Nahzno₂ + H₂o
Zn (oh) ₂ + 2NOOH = na₂zno₂ + 2h₂o
Xa i-zinc sulfate isetyenziswa yedwa, isiphumo sokuthintela kungamahlwempu. Ihlala isetyenziswa ngokudibeneyo neCyAnide, iSodium sulfide, i-Sulfite okanye i-Sulfium okanye i-Sulfium, i-Sodium Carbonate, iSodium ye-SODIM, njl njl. Umyinge oqhelekileyo osetyenzisiweyo: cynide: i-zulc sulfate = 1: 2-5. Ngeli xesha, i-CNˉ kunye ne-ZN²⁺ for colloidal zn (cn)
