Flotation-leaching tekinoroji tsika yemhangura-goridhe ore muRussia

Mune mumwe mugodhi wegoridhe muRussia, ore yegoridhe inonyanya kuratidzwa nehuwandu hwemhangura. Mushure meshanduko yehunyanzvi, mugodhi wakatarisana nematambudziko akati wandei aitadzisa kugadzirwa kwakanaka.

Matambudziko ekutanga muBeneficiation uye Metallurgy System

• Mwero weKudzoserwa kweGoridhe Rakaderera : Mushure mekushandurwa, mwero wekudzoka kwegoridhe wakaderera kusvika padanho risingagutsi, zvichitadza kuzadzisa zvinangwa zvebudiriro zvaitarisirwa.

• Kushandiswa kweSodium Cyanide Yakawanda : Kushandiswa kweSodium cyanide kwakawedzera, zvikaita kuti mari yekushandisa iwedzere zvakanyanya.

• Kuunganidzwa kweCopper Ions : Copper ions dzinogara dzichiungana musystem, zvichikonzera kugadzirwa kusina kujairika mumabasa ekuvandudza uye ekugadzira simbi.

Kuvandudzwa Kunowanikwa kuburikidza neKutsvakurudza uye Kuita

Copper Flotation Optimization

• Kuwedzera kweCopper Concentrate Goho : Goho reconstant copper rakagadziridzwa zvinobudirira kubva pa0.25% kusvika pa0.75%.

• Mwero Yekudzoreredza Yakakwira : Mwero wekudzoreredza kushanda kwegoridhe nemhangura pakudonha kwemhangura wakawedzera zvikuru. Mwero wekudzoreredza goridhe wakakwira kubva pa20% kusvika pa35%, uye mwero wekudzoreredza mhangura wakawedzera kubva pa34% kusvika pa52%.

• Kuwedzera muKudzoserwa kweGoridhe Yese : Huwandu hwegoridhe rese rekudzoka hwakakwira kubva pa87% kusvika pa89%, zvichiratidza kushanda zvakanaka kwakawedzerwa.

Leaching Process Optimization

• Nguva Yokubvisa Mvura Yakaderedzwa : Nguva yekubvisa mvura yakaderedzwa kubva pa85.48 h kusvika 56.61 h, zvichiita kuti kutenderera kwekugadzirwa kuve nyore.

• Kuwanda kweSodium Cyanide muropa : Kuwanda kweSodium Cyanide muropa kwakadzikira kubva pa1000 mg/L kusvika pa600 mg/L.

• Kuderedzwa kweKushandiswa kweSodium Cyanide : Kushandiswa kwesodium cyanide kwakadzikira kubva pa7.49 kg/t kusvika pa3.60 kg/t, zvichikonzera kuchengetedza mari.

• Mwero Wakaderera weKubviswa kweCopper : Mwero weKubviswa kweCopper wakaderera kubva pa27.18% kusvika pa20.09%, izvo zvinobatsira pakuita kwese.

Kurapa kweCopper Ion Reduction

Hydrogen Peroxide Cyanide Kuparadza uye Kubvisa Mhangura

Zvichibva paongororo yekuyedza pamusoro pekubvisa mhangura nehydrogen peroxide kuti iparadze cyanide , mukugadzirwa kwayo, nzira yakabatana yakashandiswa. Sodium metabisulfite nehydrogen peroxide zvakashandiswa pamwe chete pakurapa pasi pemamiriro ealkali yakawanda. Nzira iyi yakaderedza zvakanyanya huwandu hwemaion emhangura muore inoparadza cyanide kubva pa330.47 mg/L kusvika pa24.55 mg/L, zvichideredza zvakanyanya maion emhangura musystem.

Mhedzisiro yemaitiro ekugadzira aya anoratidza zvakajeka kuti kune iyi mhangura-ine goridhe ore muRussia, nzira dzakadai sekuwedzera mhangura flotation kudzoreredza mwero, optimize leaching mamiriro kutema sodium cyanide kushandiswa, kuitisa hydrogen peroxide cyanide kuparadza, uye kubvisa mhangura pasi pepamusoro-alkali mamiriro anogona kuburitsa yakanakisa kugadzirwa mhedzisiro. Mhosva iyi ine kutungamira kwakakura kukosha kwekugadzirisa kwebeneficiation uye metallurgy maitiro uye maitiro ekugadzira ezvakafanana mhangura-inobereka goridhe ores.
