Pfupiso yetungamira uye zinc mineral vamiririri

1. Tungamira uye Zinc Flotation Collector

Vanowanzo shandiswa vanounganidza kuti vatungamire-Zinc Ores vanosanganisira:

1. Xanthate. Rudzi urwu rweMumiriri runosanganisira Xanthate, Xanthatene Ester, nezvimwe.

2. Sulfur nitrogen, yakadai seEthyl sarufa nitrogen nitrogen nitrogen yekuunganidza simba rekuunganidza kupfuura xanthate. Iyo ine yakasimba yekuunganidza kugona kweGalena naCalcopyrite, asi kushaya simba kuunganidza pyrite, sarudzo yakanaka, kukurumidza kwekumhanyisa, uye mashoma anoshandiswa kupfuura Xanthate. Iyo ine yakasimba yekuunganidza ratio yeiyo coarse zvidimbu zve sulfide ore. Kana ichishandiswa kurongedza mhangura-inotungamira-sarufa yakatarwa maOres, inogona kuwana zviri nani kugadzirisa mhedzisiro kupfuura Xanthate.

3.Black Mushonga

Denga dema muunganidzi anoshanda weSulfide Ores, uye kugona kwekuunganidza kwacho hakuna kusimba pane izvo zve xanthate. Iyo solubility chigadzirwa che dihydrocarbyl dithhiohosphate yeiyo yakafanana simbi ion yakakura kupfuura iyo ye xanthate yeiyo inoenderana ion. Mushonga mutema une foaming zvivakwa.

Kazhinji inoshandiswa Black Pody muindasitiri inosanganisira: Kwete. 25 dema poda, but 1 Pakati pavo, butylammimu nhema poda Iyo yakakodzera kuronga kweiyo sulfide eeres senge the they yemhangura, kutungamira, zinc, uye nickel. . Mune isina kusimba alkaline slurry, kugona kwekuunganidza Pyrite uye Plrrhotite haina kusimba, asi kugona kwekuunganidza kwaGalena kwakasimba.

2. Tungamira uye Zinc Flotation Regator

Zvinoenderana nebasa ravo muhurongwa hwavo hwekurima, vanogadzirisa vanogona kukamurwa kuita: vanoratidzira, vamiriri, vepakati ph anogadzirisa, zvidhinha zvinopararira uye zvikwangwani.

Vagadzirisi vanosanganisira akasiyana-siyana inorganic makomputa (akadai semaronda, zvigadziko uye acids) uye organic commund. Mumiririri mumwechete anowanzotamba akasiyana mabasa pasi pemamiriro akasiyana ehurongwa.

Inhibitors:

1. Lime lime (cao) ine mvura yakasimba yekubata uye inobata nemvura yekuumba hydrate lime ca (OH) 2. Zvakaoma kunyungudutsira mumvura uye inonzi alkali yakasimba. Kuita kwakawedzerwa kuflotation slurry iri seinotevera:

Cao + H2O = CA (OH) 2

CA (OH) 2 = CAH ++ OO-

Caoh + = ca2 ++ 0h-

Lime inowanzoshandiswa kuwedzera iyo pH kukosha kweiyo slurry uye inhibit iron sulfide zvicherwa. MuCopper Sulfide, tungamira, uye Zinc Ores, ivo vanowanzo kuperekedzwa nesimbi sulfide Ores (Pyrite, Pyritite, Pyrrotite, Marcasite, uye Pyroarsenite (yakadai seArsenopyrite)). Kuti ubate zviri nani mhangura, kutungamira, uye zinc zvicherwa, lime inowanzowedzerwa kuti inhibit simbi sulfide zvicherwa zvicherwa.

2. Cyanide (nacn, kcn)

Cyanide inyanzvi inoshanda panguva yekutungamira uye zinc kuronga. Cyanide inonyanya kuderera sodium cyanide uye potassium cyanide, uye calcium cyanide inoshandiswawo.

Cyanide munyu wemunyu unogadzirwa neakasimba chigadziko uye chisina kusimba acid. Iyo hydrolyzed mune iyo slurry yekugadzira hcn uye cn-

KCN = K ++ CN-

Cn + h2o = hcn ++-

Zvinogona kuoneka kubva pane zviri pamusoro zvine mwero pakati zvine mwero zvekuti muAlkaline slurry, kusunganidzwa kweCN- kunowedzera, uko kunobatsira kurira. Kana iyo pH ichisunungurwa, HCN (hydrocyanic acid) inoumbwa uye inhibitory mhedzisiro yakaderedzwa. Naizvozvo, paunenge uchishandisa Cyanide, iyo alkaline chimiro cheiyo slurry inofanira kuchengetedzwa.

3.Zinc Sulfate

Iyo yakachena chigadzirwa cheZinc Sulfate ine chena kristaro, inonyudza mumvura, uye ishibitori yeSphlerite. Iyo inowanzove ine inhibitory inoshanda chete muAlkaline slurry. Iyo yakakwira iyo pH yeiyo slurry, zvakanyatsojeka inhibitory mhedzisiro. Zinc Sulfate inoburitsa inotevera maitiro mumvura:

ZNSO4 = ZN2 ++ SO42-

ZN2 ++ 2H20 = ZN (Ah) 2 + 2H +

Zn (oh) 2 ndeyemphoteric comput iyo inodonha mu acid kuti iite munyu.

ZN (OH) 2 + H2S04 = ZNSO4 + 2H2O

MuAlkaline Svikani, Hzno2- naZno22- vanowanikwa. Adsorption yavo kune zvicherwa inowedzera iyo hydrophilicity yemaminerari maficha.

ZN (OH) 2 + NAHO = Nahzno2 + H2O

ZN (OH) 2 + 2naoh = Na2zno2 + 2h2o

Kana zinc sulfate inoshandiswa yega, inhibitory inoshanda murombo. Izvo zvinowanzoshandiswa musanganiswa neCyanide, Sodium Sulfide, Sulfa kana Sudium Carbonate, nezvimwe.

Kushandiswa kwakabatanidzwa kweZinc Sulfate uye Cyanide inogona kusimudzira iyo inhibritory mhedzisiro paSphalerite. Iyo inowanzoshandiswa ratio ndeye: Cyanide: Zinc Sulfate = 1: 2-5. Panguva ino, CN- uye ZN2 + Fomu COLLOIDAL ZN (CN) 2 likepitate.
