Eco-inoshamwaridzika Goridhe Leaching Reagent uye Sodium Cyanide Synergistic Leaching yePamusoro-Giredhi Goridhe Ore

Muindasitiri yezvicherwa, kutorwa kwakanaka kwegoridhe kubva mumatombo kwakakosha zvakanyanya. Sezvo kunetsa kwezvakatipoteredza kuchikura, kusimudzirwa uye kushandiswa kwemaitiro ane hushamwari ekuchera kwave kuri kutarisisa. Ichi chinyorwa chinopa mhedzisiro yesynergistic leaching kuyedza pane yepamusoro-giredhi goridhe ore uchishandisa nharaunda inoshamwaridzana leaching agent uye Sodium Cyanide.

Eco-inoshamwaridzika Goridhe Leaching Reagent

Sodium cyanide

ziviso

Indasitiri yemigodhi yegoridhe yakagara ichivimba nemaitiro echinyakare cyanide leaching kuburitsa goridhe kubva mu ores. Nekudaro, cyanide ine muchetura zvakanyanya uye inokonzeresa njodzi dzezvakatipoteredza nekuchengetedza. Naizvozvo, pane kudikanwa kwekukurumidzira kutsvaga dzimwe nzira kana kugadzira matekinoroji anogona kuderedza kushandiswa kwecyanide uchichengetedza hunyanzvi hwekuchera. Iyo inochengetedza goridhe yekuchenesa goridhe agent inoshandiswa muchidzidzo ichi ndeimwe nzira inovimbisa, uye mhedzisiro yayo sodium cyanide yakaferefetwa kuona kugona kwekushandisa musanganiswa uyu kune yakakwira giredhi regoridhe ore.

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 ekuedza ataurwa pamusoro apa, kuyerwa kwemazinga egoridhe nesirivha akayerwa. Mhedzisiro yacho yakaratidza kuti chiyero chekuburitswa kwegoridhe chinogona kuchengetedzwa zvakadzikama pa98.07%, uye chiyero chesirivha chakasvika pa86.30%. Aya mareti epamusoro ekuleaching anoratidza kuti iyo synergistic leaching nzira uchishandisa nharaunda inoshamwaridzana goridhe leaching agent uye Sodium cyanide inoshanda zvakanyanya kune iyi yepamusoro-giredhi yegoridhe ore.

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.
