Eco-friendly Gold Leaching Reagent ndi Sodium Cyanide Synergistic Leaching of High-Grade Gold Ore

Mu makampani opanga migodi, kutunga bwino golide kuchokera ku miyala yamtengo wapatali n'kofunika kwambiri. Pamene nkhawa zokhudzana ndi chilengedwe zikukula, chitukuko ndi kugwiritsa ntchito njira zotulutsira golide zomwe siziwononga chilengedwe zakhala nkhani yofunika kwambiri. Nkhaniyi ikupereka zotsatira za kuyesa kogwirizana kwa miyala yamtengo wapatali ya golide pogwiritsa ntchito mankhwala otulutsira golide omwe ndi otetezeka ku chilengedwe komanso Sodium Cyanide.

Eco-friendly Gold Leaching Reagent

Sodium cyanide

Introduction

Makampani opanga golide akhala akugwiritsa ntchito njira zachikhalidwe zochotsera golide kuchokera ku miyala yamtengo wapatali. Komabe, cyanide ndi poizoni kwambiri ndipo imabweretsa zoopsa zazikulu pa chilengedwe ndi chitetezo. Chifukwa chake, pakufunika mwachangu kupeza njira zina kapena kupanga ukadaulo womwe ungachepetse kugwiritsa ntchito cyanide pomwe ukusunga magwiridwe antchito apamwamba ochotsera golide. Chothandizira chochotsera golide chomwe chimagwiritsidwa ntchito mu kafukufukuyu ndi njira ina yabwino, ndipo mphamvu yake yogwirizana ndi sodium cyanide idafufuzidwa kuti adziwe kuthekera kogwiritsa ntchito kuphatikiza kumeneku ku miyala yamtengo wapatali ya golide.

Zida Zoyesera ndi Njira

Makhalidwe a Ore

Mwala womwe unagwiritsidwa ntchito poyesera uku unali ndi golide wa 12.24 g/t ndi giredi yasiliva 131.91 g/t. Magiredi apamwambawa amapangitsa kukhala woyenera kuwunika momwe ntchito ya synergistic leaching ikugwirira ntchito.

Zoyeserera

• Kupukuta bwino: ~ 74 μm ndi 95%. Kupera bwino kumeneku ndikofunikira chifukwa kumawonjezera gawo la tinthu tating'onoting'ono, ndikupangitsa kuti leaching ichitike.

• Mlingo wothirira golide wochezeka ndi chilengedwe: 2 kg/t. Kuchuluka kwapadera kudatsimikiziridwa kudzera muzoyeserera zoyambira kuti zikwaniritse zotsatira za leaching.

• Mlingo wa sodium cyanide: 1 kg/t. Kuchepetsa mulingo wa cyanide ndikusunga magwiridwe antchito abwino ndi chimodzi mwazolinga zazikulu za kafukufukuyu.

• Mlingo wa laimu: 4 kg/t. Laimu amawonjezeredwa kuti asinthe pH ya zamkati, zomwe ndizofunikira kuti pakhale bata komanso kuchita bwino kwa njira yoperekera leaching.

• Kukhazikika kwa zamkati: 40%. Izi ndende amapereka malo oyenera kuti reagents leaching kuchita ndi particles ore.

• Nthawi yopuma: 24h. Pamafunika nthawi yokwanira yochotsa golide kuti golide ndi siliva zichotsedwe.

Zotsatira Zoyesera

Pansi pa mikhalidwe yoyesera yomwe yatchulidwa pamwambapa, kuchuluka kwa kuchotsedwa kwa golide ndi siliva kunayesedwa. Zotsatira zake zinasonyeza kuti kuchuluka kwa kuchotsedwa kwa golide kumatha kusungidwa bwino pa 98.07%, ndipo kuchuluka kwa kuchotsedwa kwa siliva kunafika pa 86.30%. Kuchuluka kwa kuchotsedwa kumeneku kukusonyeza kuti njira yogwirizanitsa yochotsera golide pogwiritsa ntchito chinthu choteteza chilengedwe chochotsa golide ndi Sodium cyanide ndi yothandiza kwambiri pa miyala yamtengo wapatali ya golide iyi.

Kukambirana

Kuchulukirachulukira komwe kumapezeka pakuyesaku kungabwere chifukwa cha kuphatikiza kwa golide woyezera zachilengedwe komanso sodium cyanide. Wothandizira zachilengedwe atha kupititsa patsogolo kuyambiranso kwa ore, kupangitsa kuti cyanide isavutike kuchitapo kanthu ndi golide ndi siliva. Panthawi imodzimodziyo, kuchepetsa mlingo wa sodium cyanide sikungothandiza kuchepetsa kuopsa kwa chilengedwe komanso kumachepetsanso ndalama zopangira pamlingo wina. Kusintha kwa pH ndi laimu kumathandizanso pakulimbikitsa kachitidwe ka leaching.

Kutsiliza

Kafukufukuyu akuwonetsa kuthekera kogwiritsa ntchito njira ya synergistic leaching yokhala ndi golide woyezera zachilengedwe komanso sodium cyanide pamwala wagolide wapamwamba kwambiri. Kuchulukirachulukira kwa golide ndi siliva komwe kumapezeka pansi pamikhalidwe yabwino kumawonetsa kuthekera kwakukulu kogwiritsa ntchito mafakitale. Njirayi sikuti imangowonjezera bwino m'zigawo komanso imachepetsanso kukhudzidwa kwachilengedwe komwe kumakhudzana ndi chikhalidwe cha cyanide - njira zowotchera zokha. Kufufuza kwina kungathe kuchitidwa kuti muwongolere magawo a ndondomekoyi ndikukulitsa kuchuluka kwa ntchito ku mitundu yosiyanasiyana ya golide.
