Kuyoborwa na Zinc ni ibikoresho byingenzi byibanze byiterambere ryubukungu bwimibereho. Hamwe n'iterambere ry'ubukungu bwihuse, icyifuzo cya Kill na Zinc gikomeje kwiyongera, no gutunganya neza kandi bigoye-guhitamo uburyo bwakozwe na zinc yarushijeho kwihutirwa. Ni muri urwo rwego, abakozi basanzwe batunganya amabuye y'agaciro, cyane cyane abakusanya ibikorwa bikomeye hamwe no guhitamo neza, ndetse no kwibasirwa mu bidukikije, ibiciro bike, hamwe n'ibikoresho binini, bifite akamaro gakomeye ku gutandukana neza no gutunganya ubuyobozi- amabuye ya zinc. Ibikurikira bizaguha gusobanukirwa byuzuye ubwoko bwa reagents ikoreshwa mubuyobozi-zinc or flotation.
Kuyobora na zinc flotation ya flotation
xanthate
Abakozi nkabo barimo Xanthate, Xanthate Esters, nibindi
Sulfuru na azote
Kurugero, Ethyl Sulfide ifite ubushobozi bwo gukusanya gukomeye kuruta xanthate. Ifite ubushobozi bukomeye bwa Galena na Chalcopyrite, ariko bafite intege nke zo gukusanya PYRITE, guhitamo neza, umuvuduko wihuse, kandi gukoresha bike kuruta xanthate. Ifite imbaraga zikomeye zo gukusanya uduce duto duto twa sulfide yo mu mabuye ya sulfide, kandi iyo dukoreshwa mu rwego rwo gutondekanya imisanzure-sulfur yihariye, irashobora kugera ku bisubizo nziza kuruta xanthate.
Ubuvuzi bwabirabura
Ifu yumukara ni ukusanya neza kwimitsima ya sulfide, hamwe nubushobozi bwo gukusanya bufite intege nke kuruta iya Xanthate. Ibicuruzwa byonyine bya diyddrocarbybyl dithiophoshate yicyuma kimwe ni kinini kuruta icya xanthate ya ion ihuye. Ubuvuzi bwirabura bwafite imiterere ifuro. Bikunze gukoreshwa ifu mu nganda zirimo: No. Ifu ya Gray, Butylammonium ifu yumukara, Amine yijimye yifu, na Naphherecinale yirabura. Muri bo, Butylammonium ifu y'umukara (Dibutyl Ammonium Dithiophoshate) ni ifu yera, byoroshye gushonga mu mazi, ahinduka umukara nyuma yo gukuramo, kandi afite imitungo ifungizo. Birakwiriye kuri flotation ores sulfide nkawe nkumuringa, kuyobora, zinc, na nikel. . Muburyo butandukanye bwa alkaline, ubushobozi bwo gukusanya bwa PYRITE na Pyrrhotite ni intege nke, ariko ubushobozi bwo gukusanya Galena burakomeye.
Kuyobora na zinc flotation regilator
Abayobozi barashobora kugabanywamo abibujijwe, abambere, abatangazamakuru PH, abapatanyabutumwa, coagulants na pricchelin ukurikije uruhare rwabo muri gahunda yabo muri Flotation. Abayobozi barimo ibice bitandukanye byihangana (nk'ubwinyundo, ibishingiro na acide) n'ibigo kama. Umukozi umwe akunze gukina inshingano zitandukanye mubihe bitandukanye.
Cyanide (Nacn, KCN)
Cyanide ni inzitizi nziza mugihe cya sasita na zinc itondekanya. Cyanide ahanini ni Sodium cyanide na potasim cyanide, na Calcium cyanide nayo irakoreshwa. Cyanide ni umunyu watewe na shingiro rikomeye na aside ifite intege nke. Ni hydrolyzes mubusinzi bwo kubyara HCN na CNˉ
KCN = K⁺ + CNˉ CN + H₂o = HCN⁺ + OHˉ
Duhereye kuri buringaniye hejuru, birashobora kugaragara ko muri alkaline, kwibanda kuri CNˉ byiyongera, bikaba byiza kubuza. Niba PH yamanuwe, HCN (Acide ya Hydrocyanic) yakozwe kandi ingaruka zibanga zagabanutse. Kubwibyo, iyo ukoresheje cyanide, imiterere ya alkaline yubusinzi igomba gukomeza. Cyanide ni umukozi wuburozi cyane, nubushakashatsi kumuntu wa Cyanide cyangwa cyanide-nkeya yagiye imyaka myinshi.
zinc sulfate
Igicuruzwa cyera cya Zinc SUlFate ni kirisiti yera, byoroshye gushonga mumazi, kandi ni inhibitor ya sphalerite. Mubisanzwe bifite ingaruka kubihimbano gusa muri alkaline. Isumbabyose ph of deurry, niko byanze bikunze ingaruka zayo. Zinc lulfAte itanga reaction ikurikira mumazi:
ZNSO₄ = ZN²⁺ + SO₄
Zn²⁺ + 2h ₂o = zn (OH) ₂ + 2h⁺zn (OH) ₂ ni uruganda rwa amphoteric rushonga muri aside kugirango ikore umunyu
Zn (OH) ₂ + H₂so₄ = ZNSO₄ + 2h₂o
Muri Alkazi, hzno₂ˉ na zno₂²ˉ baraboneka. Abamamaza amabuye y'agaciro yongera hydrophilicity y'amabuye y'agaciro.
Zn (oh) ₂ + naoh = nahzno₂ + h₂o
Zn (oh) ₂ + 2Naoh = na₂zno₂ + 2h₂o
Iyo zinc sulfate ikoreshwa wenyine, ingaruka zitemewe zirakennye. Mubisanzwe bikoreshwa hamwe na cyanide, sodium sulfide, sulferi cyangwa thiosulfate, edionate, nibindi bikorwa bya vinc sulfate na cyanide birashobora kuzamura ibibujijwe kuri sphalerite. Ikigereranyo cyakoreshejwe gikunze gukoreshwa ni: cyanide: zinc sulfate = 1: 2-5. Muri iki gihe, CNˉ na Zn²⁺ bagize colloidal zn (cn) ₂.
