Incamake ya Master hamwe na zinc

1. Kuyobora na zinc flotation ya flotation

Abakundwa bakoreshwa kubice bya kinc birimo:

1. Xanthate. Ubu bwoko bwa agent burimo Xanthate, Xanthate Ester, nibindi.

2. Sulfur azote, nka Ethyl Sulfuru Azote, afite ubushobozi bwo gukusanya bikomeye 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 igipimo gikomeye cyo gukusanya kubice bifatanye bya sulfide. Iyo ikoreshwa mugukemura amabuye yumuringa-sulfur yihariye, irashobora kubona ingaruka nziza zo gutondeka kuruta xanthate.

3.Byumuvuzi

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.

2. Kuyobora na zinc flotation regilator

Dukurikije uruhare rwabo muri gahunda ya Flotation, abahawe ababitswe barashobora kugabanamo: ababujijwe, abahanga, abadayimoni bashinzwe ubuyota, abapata Simoni, abapatanyabutumwa, coagulants no kongera kumera.

Abayobozi barimo ibice bitandukanye byihangana (nk'ubwinyundo, ibishingiro na acide) n'ibigo kama. Umukozi umwe akunze gukina inshingano zitandukanye mubihe bitandukanye.

Abagizi babuza:

1. Lime lime (cao) yinjira mumazi kandi yitabira amazi kugirango akore hyded lime ca (OH) 2. Biragoye gusezerera mumazi kandi ni alkali ikomeye. Reaction iyo yongewe kuri flotation slurry niyi ikurikira:

Cao + h2o = ca (oh) 2

Ca (oh) 2 = caoh ++ Oh-

Caoh + = ca2 ++ 0h-

Lime ikoreshwa kenshi kugirango wongere agaciro ph ya slurry kandi ibuza ibyuma bya senral. Mu sulfide y'umuringa, iyobowe na zinc, akenshi iherekejwe na fer sulfide ores (pyrite, pyrhotite, marcasite, na arjoartenyrite)). Kugirango urusheho kuri flotate umuringa, kuyobora, na zinc myanels, lime akenshi yongerwaho kugirango ibuza ibyuma bya sulfide.

2. 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 hydrolyzed mubusinzi kugirango itange HCN na CN-

KCN = K ++ CN-

Cn + h2o = hcn ++ Oh-

Irashobora kugaragara mubigereranyo byavuzwe haruguru ko muri alkaline slurry, kwibanda kuri CN- kwiyongera, nibyo bigirira akamaro kubuza. Niba PH yamanuwe, HCN (Acide ya Hydrocyanic) yakozwe kandi ingaruka zibanga zagabanutse. Kubwibyo, iyo ukoresheje cyanide, imiterere ya alkaline yubusinzi igomba gukomeza.

3.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 ++ Sol2-

Zn2 ++ 2H20 = ZN (OH) 2 + 2H +

Zn (oh) 2 nintoki za amphoteric zishonga muri aside kugirango zibe umunyu.

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

Muri Alkazi, hzno2- na Zno22- barabonetse. 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, sodium karubone, nibindi.

Gukoresha isura ya zinc sulfate na cyanide birashobora kuzamura ibanga kuri sphalerite. Ikigereranyo cyakoreshejwe gikunze gukoreshwa ni: cyanide: zinc sulfate = 1: 2-5. Muri iki gihe, CN- na ZN2 + ishusho ya colloidal zn (cn) 2 imvura.
