Basa rePotassium Permanganate muMurwi Leaching Goridhe Kuchera Maitiro

Munzvimbo ye kutorwa kwegoridhe, ivo murwi leaching maitiro akabuda senzira inodhura uye inoshanda, kunyanya kune yakaderera-giredhi goridhe ores. Pakati peakasiyana reagents anoshandiswa mukuita uku, potasium permanganate (\(KMnO_4\)) inoita basa rakakosha uye rine mativi mazhinji rinokanganisa zvakanyanya kushanda kwese uye kushanda kwekuchera goridhe. Ichi chinyorwa chinotarisa mune chaiwo mabasa uye zvakanakira potassium permanganate mumurwi leaching goridhe kudhirowa maitiro.

Chemical Properties yePotassium Permanganate

Potassium permanganate ine simba oxidizing agent, inoratidzwa neyakadzama yepepuru ruvara muchimiro chakasimba uye kugona kwayo kunyungudika mumvura, ichigadzira mhinduro yepepuru. Munzvimbo ine mvura, \(KMnO_4\) inoparadzanisa kuita potassium ions (\(K^+\)) ​​uye permanganate ions (\(MnO_4^-\)). Iyo permanganate ion inoshanda zvakanyanya uye ine tsika yakasimba yekugamuchira maerekitironi, zvichiita kuti ive yakanakisa oxidant mukuita kwemakemikari. Iyi oxidizing pfuma ndiyo hwaro hwekushanda kwayo mumirwi leaching process.

Oxidation yeSulfid Minerals

Rimwe remabasa ekutanga e potassium permanganate mumurwi leaching ndeye oxidation yemaminerari e sulfide anowanzo kuwanikwa mune goridhe ores. Sulfides, senge pyrite uye arsenopyrite, kazhinji inoputira zvimedu zvegoridhe, kudzivirira leaching agent kubva pakusangana negoridhe. Potassium permanganate oxidizes aya sulfide zvicherwa kuburikidza nekuita redox. Iyi oxidation process inopwanya matrix esulfide, ichifumura zvimedu zvegoridhe zvakavharirwa. Nekuda kweizvozvo, iyo inotevera leaching agent, kazhinji cyanide kana thiourea, inogona kunyatsonyungudutsa goridhe, ichiwedzera chiyero chekuchera.

Pre-oxidation yeEnhanced Gold Dissolution

Pamusoro pekuputsa zvipingamupinyi zve sulfide, potassium permanganate pre - oxidizes pamusoro pegoridhe. Ndarama, munharaunda yayo, ine reactivity yakaderera. Nekudaro, kuburikidza neoxidation ne potassium permanganate, mutete mutete wegoridhe oxide unoumbwa pamusoro. Iyi oxidized goridhe layer inowedzera kuita kune leaching agent. Semuyenzaniso, kana uchishandisa cyanide sechinhu chinopinza, iyo oxidized goridhe pamusoro inobata zviri nyore ne cyanide ions kuita goridhe rinonyungudika - cyanide complexes. Nekusimudzira iyi pre-oxidation, potassium permanganate inowedzera zvakanyanya mwero wekunyungudika kwegoridhe, nekudaro ichivandudza kudzoreredza kwegoridhe rose mumurwi wekucheka.

Kudzora Iyo Leaching Environment

Potassium permanganate inoitawo basa mukudzora mamiriro emakemikari mukati memurwi weleach. Inobatsira kuchengetedza yakakodzera oxidation - kuderedza mukana (ORP) mune leaching mhinduro. ORP yakakodzera yakakosha pakushanda kunoshanda kwemaitiro ekuleaching. Nekugadzirisa iyo ORP, potassium permanganate inova nechokwadi chekuti leaching reactions inoenderera pasi pemamiriro akakwana. Uyezve, inogona kuokisisa zvimwe zvinhu zvinodzikisira zviripo muore, senge organic matter, izvo zvinogona kuvhiringa maitiro egoridhe leaching. Nekubvisa izvi zvinokanganisa zvinhu, potassium permanganate inobatsira kusimudzira kusarudzwa kwekunyungudika kwegoridhe, kuderedza huwandu hwetsvina yakanyungudika pamwe negoridhe.

Zvakanakira Murwi Leaching Goridhe Kuchera

Kushandisa potassium permanganate mumurwi leaching kunopa zvakati wandei zvakanakira. Chekutanga, inonatsurudza mwero wekudzoreredzwa kwegoridhe rose, izvo zvakakosha zvakanyanya pakubudirira kwehupfumi hwekucherwa kwegoridhe. Nekunyatso oxidizing zvicherwa zvesulfide uye kusimudzira kunyungudika kwegoridhe, zvinoita kuti kutorwa kwegoridhe rakawanda kubva kune yakaderera-giredhi ores. Chechipiri, inoderedza kutsamira kune ane hukasha uye anogona kukuvadza nharaunda leaching agents. Sezvo ichiwedzera kuitazve kwegoridhe uye kuputsa zvipingamupinyi zve sulfide, kusangana kweiyo main leaching agent dzimwe nguva inogona kudzikiswa, ichideredza kukanganisa kwezvakatipoteredza. Pamusoro pezvo, potassium permanganate iri nyore kubata uye kuchengeta, uye maitiro ayo zvigadzirwa kazhinji hazvina muchetura kana zvichienzaniswa nemamwe maoxidizing agents anoshandiswa mumigodhi.

Mukupedzisa, potassium permanganate inoshanda seyakakosha reagent mumurwi wekucheka goridhe maitiro. Mabasa ayo mune oxidizing sulfide zvicherwa, pre-oxidizing goridhe yekuwedzeredzwa kunyungudika, uye kutonga nharaunda yeLeaching inobatsira zvakanyanya mukuvandudza goridhe kudzoreredza mitengo uye kugona kwese kwemaitiro ekubvisa. Sezvo indasitiri yezvicherwa ichiramba ichitsvaga nzira dzakasimba uye dzakasimba dzekuchera, basa re potassium permanganate mukudonha kwemurwi rinogona kuramba rakakosha, uye kumwe kutsvagisa kunogona kuburitsa nzira dzakanyatsogadziriswa dzekushandisa iyi kemikari inogoneka.
