Kwambara Ore | Gusobanukirwa inzira ya Flotation ya Mala-zinc sulfide ore

Ihame ryakoreshejwe rya Fritation rikoreshwa mugutunganya umurongo-zinc sulfide amabuye y'agaciro arimo kopi yibanze, flotation ivanze hamwe na flotation ingana.

Nubwo inzira ikoreshwa, uzahura nibibazo byo gutandukana na zinc no gutandukana na zinc-sulfuru. Urufunguzo rwo gutandukana ni uguhitamo abishyira mu gaciro kandi hasi.

Kubera ko Galena nyinshi ari nziza kuruta uko yaguye, uburyo bwose bwo guhagarika Zinc na Manist Kureremba bikoreshwa. Ibisubizo byimiti yo kubuza zinc birimo uburyo bwa Cyanide na cyanide uburyo bwa cyanide. Muburyo bwa Cyanide, lulfate ya zinc ikoreshwa muguhuza na cyanide kugirango izamure ibanga. Kurugero, uruganda runaka rutunganya rukoresha sodium cyanide na zinc sulfate kugirango igabanye igipimo cya cyanide kugeza 20 ~ 30G / T, ndetse bamwe bakayigabanya kuri 3 ~ 5g / t. Imyitozo yagaragaje ko idagabanya gusa dosiye, ahubwo yongera igipimo cyo gukira.

Mu rwego rwo kwirinda umwanda wa cyanide kubidukikije, Free-Ubuntu cyangwa Cyanide-nkeya kuri ubu hazamurwa mu rugo no mu mahanga. Uburyo bwa cyanide ikurikira bukoreshwa mubuyobozi bwinganda na zinc:

1. Kureremba Kurere Kubuza Zinc

(1) zinc sulfate + sodium karubone (cyangwa sodium sulfide cyangwa lime);

Ibyanjye bimwe na bimwe bya kinc-sulfutu byasabye inzira yihariye ya Flotation. ZNSO4 + NA2CO3 (1.4: 1) yakoreshejwe muguhagarika imbaraga mugihe ureremba. Ugereranije n'ubwo buryo bwa Cyanide, umuyobozi uyobora icyiciro cyiyongereye kuva ku 31.12% kugeza kuri 41.80%, amanota ya Zinc yiyongereye kuva kuri 43.59% kugeza 48.43%, na Igipimo cyo gukira cyiyongereye kuva 88.54% kugeza 90.03%.

(2) zinc sulfate + sulfite;

(3) zinc sulfate + thiosulfate;

(4) sodium hydroxide (PH = 9.5, yakusanyirijwe hamwe nifu yirabura);

(5) koresha zinc sulfate wenyine kugirango ubuza zinc;

(6) Koresha gaze ya So2 kugirango uhagarike Zinc.

2. Kureremba Zinc Guhagarika kuyobora

(1) lime;

(2) ikirahuri cy'amazi;

(3) Ikirahure cy'amazi + sodium sulfide.

Uburyo butatu bwavuzwe haruguru bukoreshwa mugihe Galena yabyaye cyane kandi kureremba kwayo kuba umukene.

Kureremba hejuru, imiti yumukara na xanthate akenshi ikoreshwa nkabahuzu, cyangwa ethyl sulfide wenyine hamwe nuburyo bwiza bukoreshwa nkukusasu. Ibimera bimwe byubuhanga nabyo bivanga aside sulfosuccine (a-22) hamwe na xanthate.

Kubera ko lime ifite ingaruka zibuza Galena, mugihe hari piyaho ntoya mubyatsi, nibyiza gukoresha tarbonate ya sodium nka ph ishishikarizwa kureremba. Iyo ibirimo pyrite muri ore ari hejuru, nibyiza gukoresha lime nka ph adgraster. Kuberako lime ishobora kubuza pyrite ijyanye na Pyrite, nibyiza kureremba.

Kuzura SPHOLERITE yahagaritswe ukoresheje sulfate yumuringa. Kugirango wirinde sulfate yumuringa na xanthate ikora umuringa xanthate mugihe cyo kuvanga cyangwa kugabanya ibikorwa bya agent, muri saperi yongeyeho mbere, hanyuma xanthate yongeyeho nyuma yo gukangura iminota 3 kugeza kuri 5.

Iyo hari ibice bibiri byoroshye kureremba hamwe nibigoye kureremba muri sphalerite, kugirango barohereze imiti iyobowe na zinc, inzira ireremba irashobora kwemezwa, ikoresha cyane cyane iyobora kandi ireremba na zinc.

3.Medid kuri zinc no gutandukana

(1) Kureremba Zinc Guhagarika Sulfure

1. Uburyo bwa lime

Ubu ni bwo buryo bwo guhagarika sulfure. Ubu buryo burashobora gukoreshwa mugutunganya inkweto mbi hamwe na zinc-sulfure ivanze yibanda. Mugihe ukoresheje ubu buryo, koresha lime kugirango uhindure pH, mubisanzwe hejuru ya 11, kugirango uwahaguruke. Ubu buryo bworoshye, kandi imiti ikoreshwa ni lime, ihendutse kandi byoroshye kubona. Ariko, gukoresha lime birashobora gutera gupima ibikoresho bya flotation, cyane cyane imiyoboro, kandi sulfure yibanda ko bidahwitse kuyungurura, bikavamo ubuhemu bwinshi bwibanze.

2.Uburyo

Kuri pyrite zimwe hamwe nibikorwa byinshi bya plassique, guhagarika uburyo bwa lime akenshi ntacyo bikora. Iyo ibitotsi bishyuha, impamyabumenyi yubuso bwa sphalerite na pyrite baratandukanye. Nyuma ya zinc-sulfuru ivanze yibandaho irashyuha, igateganywa kandi irabyutsa, ivanze ya PYRIITE iragabanuka, mugihe ibisigaye bya sphalerite bisigaye.

Ubushakashatsi bwerekana ko Zinc na Sulfuru bashobora gutandukana no gushyushya ikositimu yo gutandukanya Zinc-sulfuru kuvanga. Ubushyuhe bwo gutandukanya ubupfura ni 42 ~ 43 ° C, no gutandukana neza tutarimo gushyushya cyangwa kongera imiti iyo ari yo yose irashobora gutandukanya Zinc na sulfure. Ironderero ryabonetse ni 6.2% hejuru ya zinc ikozwe muburyo bwa lime, kandi igipimo cyo gukira ni 4.8%.

3. Lime wongeyeho umubare muto wa cyanide

Iyo lime wenyine udashobora guhagarika isura yicyuma, ongeraho umubare muto wa cyanide (urugero: nacn5g / t mu ruganda rutunganya ya Hesan, Nacn20G / T mu gutunganya igihingwa) kugirango utezimbere ya zinc-sulfur.

(2) Kureremba Sulfuru Guhagarika Zinc

Dioxyde de + uburyo bwo gushyushya uburyo ubwo buryo bwakoreshejwe mu ruganda rwa minerral ya Brunswick muri Kanada. Zinc yibanda ku gihingwa kirimo Pyrite nyinshi. Kugirango utezimbere ubuziranenge, ibitonyanga bifatwa na gaze ya dioxyde de sulfur hanyuma akubita igikona kugirango ahagarike zinc na sulfure.
Uburyo bwihariye ni ukumenyekanisha gaze ya dioxyde deulfur kuva hepfo yikigega cyambere cyo gukangurira no kugenzura ph = 4.5 kugeza 4.8. Gutera inshinge mu bigega bya kabiri n'icya gatatu bitera imbaraga no gushyushya kugeza 77 kugeza 82 ° C. Iyo igikomere cya Pyrite, PH ni 5.0 ~ 5.3, na Xanthate ikoreshwa nkabakusanya. Imiyoboro ya flotation ni zinc ya nyuma. Usibye pyrite, ibicuruzwa byabi birimo zinc. Nyuma yo gutoranywa, ikoreshwa muburyo bwo hagati kandi isubira mubutatu bwo hagati imbere yinzira yo gusubirwamo. Igenzura ryukuri rya PH nubushyuhe nurufunguzo rwiki gikorwa. Nyuma yo kuvurwa, ibicuruzwa bya zinc byiyongereye kuva 50% kugeza 51% zinc kugeza 57% kugeza 58%.
