Lead Oxide Inosimudzira Kubuda kweGoridhe muCyanide Tailings

ziviso

Cyanidation inzira inoshandiswa zvakanyanya kuburitsa goridhe kubva mumatombo. Zvisinei, cyanide miswe kazhinji iine huwandu hwegoridhe rasara, iro rakaoma kudzoka nekuda kwesimba rezvicherwa zvakabatana. Kuvandudza kukwenenzvera kwegoridhe kubva cyanide tailings yakakosha zvikuru pakugadzirisazve zviwanikwa uye mabhenefiti ehupfumi. Mukutsvakurudza kwemazuva ano, zvakaonekwa kuti lead oxide inogona kuita basa rakanaka mukusimudzira kudonha kwegoridhe mumaswe ecyanide.

Dambudziko reKudzika Goridhe Leaching Rate muCyanide Tailings

Dambudziko guru mukudzoreredza goridhe kubva kune cyanide tailings riri mune yakaoma mineralogical kuumbwa. Residual cyanide mumiswe inogona kuita kuti goridhe riite nemasulfides esimbi yakabatana (senge pyrrhotite). Kuita uku kunoumba Au/Sx passivation firimu pamusoro pezvikamu zvegoridhe. Iyi firimu yekufambisa inoita sechipinganidzo, ichidzivirira kubata kunoshanda pakati pegoridhe necyanide mhinduro, zvichikonzera kuderera kwakajairika. leaching rate yegoridhe.

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 yekuedza yakaratidza kuti kuwedzerwa kwe lead oxide kwakawedzera zvakanyanya kukwenenzverwa kwegoridhe mumaswe ecyanide. Kuenzaniswa neboka rekutonga pasina lead oxide yekuwedzera, iyo goridhe richidonha mwero wakawedzera nechikamu chinoshamisa. Semuyenzaniso, mune zvimwe zviedzo, mwero wegoridhe wekutengesa wakawedzera kubva pamutengo wakaderera kusvika pamusoro pe [X]%. Panguva imwecheteyo, kushandiswa kwe Sodium Cyanide yakaderedzwawo kusvika kumwero wakati. Ongororo yeSEM ​​neXPS yakasimbisazve kuti lead oxide yakanyatsoita neiyo passivation firimu pamusoro pegoridhe, uye zvinhu zvitsva zvemakemikari zvakaonekwa pamusoro pezvimedu zvegoridhe mushure mekuwedzera kwe lead oxide, iyo yaienderana neyakarongwa kuita maitiro.

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.
