Lead Oxide Inosimudzira Kubuda kweGoridhe muCyanide Tailings

ziviso

Kubvisa goridhe kubva mumatombo esimbi (cyanidation) inzira inoshandiswa zvakanyanya pakubvisa goridhe kubva mumatombo esimbi. Zvisinei, marara ecyanide anowanzova nehuwandu hwakati hwegoridhe rasara, izvo zvinonetsa kuwana nekuda kwekushandiswa kwezvicherwa zvine chekuita nazvo. Kuvandudza kushanda kwegoridhe kubva mumarara ecyanide kwakakosha zvikuru pakugadzirisa zviwanikwa uye mabhenefiti ehupfumi. Mukutsvagisa kwazvino, zvakaonekwa kuti lead oxide inogona kuita basa rakanaka mukuwedzera kuburitsa goridhe kubva mumarara ecyanide.

Dambudziko reKudzika Goridhe Leaching Rate muCyanide Tailings

Dambudziko guru mukuwana goridhe kubva mutsvina yecyanide riri mukugadzirwa kwakaoma kwemineralological. Cyanide yasara mutsvina inogona kukonzera kuti goridhe riite nemasulfide esimbi yakabatana (senge pyrrhotite). Kuita uku kunoita firimu reAu/Sx passivation pamusoro pezvidimbu zvegoridhe. Firimu iri repassivation rinoshanda sechipingamupinyi, richidzivirira kusangana kwakanaka pakati pegoridhe necyanide solution, zvichiita kuti goridhe risaburitse mvura yakawanda.

Sei Lead Oxide Inosimudzira Goridhe Leaching

Chemical Reaction Mechanism

Lead oxide inotora chikamu mukuwanda kwemakemikari maitiro panguva yeleaching process. Chekutanga, lead oxide inogona kuita neiyo passivation firimu inoumbwa pamusoro pegoridhe. Kuita uku kunoputsa firimu rekufambisa, richirishandura kuita munyu unonyungudika. Nekuda kweizvozvo, nzvimbo yegoridhe inoburitswa zvakare, ichibvumira cyanide kuita negoridhe. Kechipiri, lead oxide inogona kuita seoxidant muleaching system. Muhupo hwe lead oxide, iyo oxidation inogoneka ye system inogadziriswa, iyo inobatsira kuti oxidation yegoridhe igadzire soluble gold cyanide complexes.

Electrochemical Mechanism

Pane mutsauko wemagetsi unokwanisa pakati pegoridhe nechigadzirwa chekudzikisa chelead oxide. Uyu mutsauko unogona kuita kuti kuumbwa kwebhatiri rekutanga mukati meiyo leaching system. Mune iyi bhatiri rekutanga, goridhe rinoshanda seanode uye rinopinda oxidation, ukuwo kudzikisa chigadzirwa chelead oxide chinoshanda se cathode. Iyi electrochemical process, inozivikanwa sekubata corrosion, inonyatso mhanyisa kuparara kwegoridhe, nekudaro inovandudza mwero wekutorwa kwegoridhe.

Kuongorora Kuongorora

Kuedza Zvishandiso uye Nzira

Vatsvakurudzi vakasarudza vanomiririra cyanide tailings samples yekuedza. Masamples ematailings akatanga kuratidzwa kuti aone kuumbwa kwawo kwemamineral uye zvegoridhe. Zvadaro, huwandu hwakasiyana hwe lead oxide hwakawedzerwa kune cyanide leaching system. Mamiriro ekucheka, senge nguva yekudonha, tembiricha, uye cyanide concentration, yakanyatsodzorwa. Mutsara wekuedza kwakafanana kwakaitwa kuti kuve nechokwadi chekururama kwemigumisiro. Pamusoro pezvo, matekiniki epamusoro ekuongorora, senge scanning electron microscopy (SEM) uye X-ray photoelectron spectroscopy (XPS), akashandiswa kuongorora mamiriro epamusoro morphology uye shanduko yemakemikari ekuumbwa kwezvikamu zvegoridhe zvisati zvaitika uye mushure mekudonha.

Zviongorudzo Zvitsva

Mhedzisiro yekuyedza yakaratidza kuti kuwedzerwa kwe lead oxide kwakawedzera zvakanyanya kushanda kwegoridhe mukubvisa cyanide tailings. Zvichienzaniswa neboka rekudzora risina kuwedzera lead oxide, mwero wekuburitsa gold wakawedzera nechikamu chinoshamisa. Semuenzaniso, mune dzimwe bvunzo, mwero wekuburitsa gold wakawedzera kubva pamutengo wakaderera kusvika pamusoro pe [X]%. Panguva imwe chete, kushandiswa kweSodium Cyanide kwakadzikirawo kusvika pamwero wakati. Ongororo yeSEM ​​neXPS yakasimbisa zvakare kuti lead oxide yakapindura nefirimu repasi pamusoro pegoridhe, uye zvinhu zvitsva zvemakemikari zvakaonekwa pamusoro pezvidimbu zvegoridhe mushure mekuwedzera lead oxide, izvo zvaienderana nemaitiro ekuita aikurudzirwa.

Application Prospect

Kuwanikwa kwekushandisa lead oxide kusimudzira kubuda kwegoridhe mumatsetse ecyanide kune tarisiro yakakura yekushandisa. Muindasitiri yemigodhi, tekinoroji iyi inogona kuiswa kune iripo cyanide tailings mishonga yekurapa. Nekungowedzera lead oxide kune iyo leaching process, iyo yekudzoreredza goridhe inogona kuvandudzwa pasina hukuru hwekuvandudza michina. Izvi hazvingo wedzera kukosha kwehupfumi hwematailings zviwanikwa asi zvakare zvinoderedza kukanganiswa kwezvakatipoteredza kunokonzerwa nekuchengetwa kwenguva refu kwemasara ane goridhe. Zvakare, iyi nzira inogona zvakare kukwidziridzwa kukurapa kweimwe refractory goridhe ores, ichipa mhinduro nyowani yekunyatso kutorwa kwegoridhe zviwanikwa.

Mukupedzisa, lead oxide inoratidza kugona kukuru mukusimudzira kudonha kwegoridhe mumaswe ecyanide. Kuburikidza nekunzwisisa kwakadzama kwemagadzirirwo ayo ekusimudzira uye kuenderera mberi nekugonesa kwemamiriro ekuyedza, tekinoroji iyi inotarisirwa kuita basa rakakosha mukusimudzira indasitiri yezvicherwa zvegoridhe.
