Muindasitiri yemigodhi, kuburitsa goridhe kubva mumatombo zvine hungwaru kwakakosha zvikuru. Sezvo kunetseka nezvezvakatipoteredza kuri kuwedzera, kuvandudzwa nekushandiswa kwenzira dzekubvisa goridhe zvine hungwaru kwave chinhu chikuru chakanyanya kutariswa. Chinyorwa chino chinopa mhedzisiro yekuyedza kwekubatanidza goridhe repamusoro-soro uchishandisa chinhu chinobvisa goridhe chine hungwaru uye Sodium Cyanide.
Eco-inoshamwaridzika Goridhe Leaching Reagent
Sodium cyanide
ziviso
Indasitiri yekuchera goridhe yagara ichivimba nemaitiro echinyakare ekubvisa cyanide kubva mumatombo. Zvisinei, cyanide ine chepfu yakawanda uye inokonzera njodzi huru dzezvakatipoteredza nekuchengetedza. Nokudaro, pane chikonzero chekukurumidzira kutsvaga dzimwe nzira kana kugadzira matekinoroji anogona kuderedza kushandiswa kwecyanide uku ichichengetedza kushanda zvakanaka kwekubvisa goridhe. Mushonga wekubvisa goridhe usina njodzi kunharaunda wakashandiswa muchidzidzo ichi inzira yakanaka, uye kushanda kwayo pamwe chete nesodium cyanide kwakaongororwa kuti zvionekwe kuti zvinokwanisika here kushandisa musanganiswa uyu kune matombo egoridhe epamusoro.
Kuedza Zvishandiso uye Nzira
Ore Hunhu
Chicherwa chakashandiswa muchiyedzo ichi chaive negiredhi regoridhe re12.24 g/t uye sirivheri giredhi re131.91 g/t. Aya mamakisi akakwira anoita kuti ive mumiriri akakodzera wekuongorora kushanda kweiyo synergistic leaching process.
Experimental Conditions
Kukuya fineness: ~ 74 μm yakaverengerwa 95%. Uku kukuya kwakanaka kwakakosha sezvo kuchiwedzera nzvimbo yepasi pezvimedu zveore, kufambisa maitiro ekudonha.
Nezvakatipoteredza goridhe leaching agent dosage: 2 kg/t. Iyo chaiyo mari yakatemerwa kuburikidza nekutanga kuyedza kugadzirisa iyo leaching maitiro.
Sodium cyanide dosage: 1 kg/t. Kudzikisa muyero wecyanide uku uchiramba uchiita basa rekuita zvakanaka ndicho chimwe chezvinangwa zvikuru zvechidzidzo ichi.
Lime dosage: 4 kg/t. Lime inowedzerwa kugadzirisa pH yepulp, iyo yakakosha pakugadzikana uye kushanda kweiyo leaching process.
Pulp concentration: 40%. Uku kusungirirwa kunopa nharaunda yakakodzera kune iyo leaching reagents kuti iite neiyo ore zvimedu.
Nguva yekushanda: 24h. Nguva yakakwana yeleaching inodiwa kuti ive nechokwadi chekuti goridhe nesirivha zvanyatsoburitswa.
Zviongorudzo Zvitsva
Pasi pemamiriro ezvinhu ekuyedza ataurwa pamusoro apa, mwero wekubviswa kwegoridhe nesirivha wakayerwa. Zvakabuda zvakaratidza kuti mwero wekubviswa kwegoridhe unogona kuchengetedzwa zvakanaka pa98.07%, uye mwero wekubviswa kwesirivha wakasvika 86.30%. Mwero uyu wepamusoro wekubviswa kwegoridhe unoratidza kuti nzira yekubatanidza gold leaching inoshandisa zvakatipoteredza uye Sodium cyanide inoshanda zvikuru kune iyi gold ore yepamusoro.
hurukuro
Huwandu hwepamusoro hwakawanikwa mukuyedza uku hunogona kuverengerwa kune yakasanganiswa chiitiko chezvakatipoteredza goridhe leaching agent uye sodium cyanide. Mushandi ane hushamwari kwezvakatipoteredza anogona kuwedzera kudzoreredzwa kweiyo ore pamusoro, zvichiita kuti zvive nyore kuti cyanide iite negoridhe nesirivha. Panguva imwecheteyo, iyo yakaderedzwa dosage yesodium cyanide haingobatsiri kuderedza njodzi kwezvakatipoteredza asiwo inodzikisa mutengo wekugadzira kune imwe nhanho. Iko kugadziridzwa kwepH neraimu kunoitawo basa rakanaka mukusimudzira leaching reaction.
mhedziso
Chidzidzo ichi chinoratidza kugona kwekushandisa nzira yesynergistic leaching ine nharaunda inochengetedza goridhe leaching agent uye sodium cyanide yemhando yepamusoro yegoridhe ore. Huwandu hwepamusoro hwegoridhe nesirivheri hunowanikwa pasi pemamiriro akakwenenzverwa hunoratidza kugona kukuru kwekushandiswa kwemaindasitiri. Iyi nzira haingonatsiridza mashandiro ekutora asi zvakare inoderedza kukanganiswa kwezvakatipoteredza kwakabatana neyechinyakare cyanide - chete leaching maitiro. Kumwe kutsvagisa kunogona kuitwa kukwirisa maitiro maparamendi mberi uye kuwedzera chiyero chekushandisa kune akasiyana marudzi egoridhe ores.
