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

M'makampani amigodi, kutulutsa bwino kwa golidi kuchokera ku miyala ndikofunika kwambiri. Pamene nkhawa za chilengedwe zikukula, chitukuko ndi kugwiritsa ntchito njira zochotsera zachilengedwe zakhala zofunikira kwambiri. Nkhaniyi ikupereka zotsatira za kuyesa kwa synergistic leaching pa miyala yagolide yapamwamba kwambiri pogwiritsa ntchito njira yoteteza zachilengedwe komanso Sodium Cyanide.

Eco-friendly Gold Leaching Reagent

Sodium cyanide

Introduction

Makampani opanga migodi ya golide kwa nthawi yayitali amadalira njira zachikhalidwe za cyanide kuti azichotsa golide ku ores. Komabe, cyanide ndi poyizoni kwambiri ndipo imabweretsa zoopsa zachilengedwe komanso chitetezo. Chifukwa chake, pakufunika mwachangu kupeza njira zina kapena kupanga matekinoloje omwe angachepetse kugwiritsa ntchito cyanide ndikusunga magwiridwe antchito apamwamba. Wothandizira zachilengedwe wowotchera golide wogwiritsidwa ntchito mu kafukufukuyu ndi njira ina yodalirika, ndipo zotsatira zake ndi sodium cyanide adafufuzidwa kuti adziwe kuthekera kogwiritsa ntchito kuphatikiza kumeneku ku miyala yagolide yapamwamba.

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 paziyeso zomwe zatchulidwa pamwambapa, kuchuluka kwa golide ndi siliva kunayesedwa. Zotsatira zake zidawonetsa kuti kutsika kwa golide kutha kusungidwa bwino pa 98.07%, ndipo kuchuluka kwa siliva kumafika 86.30%. Miyezo yayikuluyi ikuwonetsa kuti njira ya synergistic leaching yomwe imagwiritsa ntchito njira yowotchera golide ndi chilengedwe. Sodium cyanide ndi othandiza kwambiri pazitsulo zagolide zapamwambazi.

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.
