Umkhuba wobuchwepheshe be-Flotation-leaching of ore yethusi-igolide eRussia

Emayini ethile yegolide eRussia, i-ore yegolide ibonakala ngokuyinhloko ngethusi eliningi. Ngemva kwenguquko yezobuchwepheshe, imayini ibhekane nezinselelo ezimbalwa ezithiya ukukhiqizwa okuphumelelayo.

Izinselelo Zokuqala Kuhlelo Lokuhlomula kanye Nensimbi

• Izinga Lokubuyisa Igolide Eliphansi : Ngemva kokuguqulwa, izinga lokubuyisa igolide lehle laya ezingeni elingagculisi, lahluleka ukuhlangabezana nemigomo yokukhiqiza elindelwe.

• Ukusetshenziswa Okuphezulu kwe-Sodium Cyanide : Ukusetshenziswa kwe -Sodium cyanide kwanda kakhulu, kwakhulisa izindleko zokusebenza kakhulu.

• Ukuqongelelana kwama-Ion e-Copper : Ama-ion e-Copper ahlala eqongelela ohlelweni, okubangela ukukhiqizwa okungajwayelekile ezinqubweni zokuzuza kanye nezokubumba insimbi.

Ukuthuthukiswa Okuzuzwe Ngocwaningo Nokwenza

Ukuthuthukisa I-Copper Flotation

• Ukwanda Kokuqoqwa Kwethusi : Ukuqoqwa kwethusi kulungiswe ngempumelelo kusuka ku-0.25% kuya ku-0.75%.

• Amazinga Okululama Aphezulu : Amazinga okululama kokusebenza kwegolide nethusi ekujuleni kwethusi abonise ukwanda okukhulu. Izinga lokululama kwegolide lenyuke lisuka ku-20% laya cishe ku-35%, kanti izinga lokululama kwethusi lenyuke lisuka ku-34% laya cishe ku-52%.

• Ukwanda Kokubuyiselwa Kwegolide Eliphelele : Izinga lokubuyiselwa kwegolide eliphelele lenyuke lisuka ku-87% laya ku-89%, okubonisa ukusebenza kahle okuthuthukisiwe.

Ukuthuthukiswa Kwenqubo Ye-Leaching

• Isikhathi Sokukhuculula Esincishisiwe : Isikhathi sokukhuculula sincishisiwe kusukela emahoreni angu-85.48 kuya emahoreni angu-56.61, okwenza umjikelezo wokukhiqiza ube lula.

• Ukuhlushwa kwe-Sodium Cyanide Ephansi : Ukuhlushwa kwe -Sodium Cyanide kwehlisiwe kusuka ku-1000 mg/L kuya cishe ku-600 mg/L.

• Ukwehla Kokusetshenziswa kwe-Sodium Cyanide : Ukusetshenziswa kwe -sodium cyanide kwehle kusuka ku-7.49 kg/t kuya ku-3.60 kg/t, okwaholela ekongeni izindleko.

• Izinga Eliphansi Lokukhuculula Ithusi : Izinga lokukhuculula ithusi lehle lisuka ku-27.18% laya ku-20.09%, okuwusizo enqubweni iyonke.

Ukwelashwa Kwe-Copper Ion Reduction

I-Hydrogen Peroxide Cyanide Ukubhujiswa kanye Nokususwa Kwethusi

Ngokusekelwe ocwaningweni lokuhlola mayelana nokususwa kwethusi yi-hydrogen peroxide ukuze kubhujiswe i-cyanide , ekukhiqizweni, kwamukelwa indlela ehlanganisiwe. I-Sodium metabisulfite kanye ne-hydrogen peroxide kwasetshenziswa ndawonye ekwelapheni ngaphansi kwezimo ezinama-alkali amaningi. Le ndlela yanciphisa ngempumelelo okuqukethwe kwe-copper ion ku-ore yokubhujiswa kwe-cyanide kusuka ku-330.47 mg/L kuya ku-24.55 mg/L, okunciphisa kakhulu ama-copper ion ohlelweni.

Imiphumela yale mikhuba yokukhiqiza ikhombisa ngokusobala ukuthi kule nsimbi yegolide enethusi eRussia, amasu afana nokwandisa izinga lokutholwa kokuntanta kwethusi, ukwenza kahle izimo zokucwilisa ukusika ukusetshenziswa kwe-sodium cyanide, ukucekela phansi i-hydrogen peroxide cyanide, nokususa ithusi ngaphansi kwezimo ze-alkali ephezulu kungaveza imiphumela emihle kakhulu yokukhiqiza. Leli cala linomhlahlandlela omkhulu wokuthuthukisa izinqubo zokuhlomula nezokusansimbi kanye nezinqubo zokukhiqiza zamatshe egolide anethusi afanayo.
