Carbon Slurry Cyanidation: Njira Yobwezeretsa Golide kuchokera ku Copper Tailing

Introduction

Mu makampani opanga migodi, kupeza bwino zitsulo zamtengo wapatali kuchokera ku zitsulo za m'mbuyo ndikofunikira kwambiri pakugwiritsa ntchito chuma komanso kuteteza chilengedwe. Phunziroli likuyang'ana kwambiri mgodi wa mkuwa ku Central Asia, komwe CarbonNjira yothira mchere mu pulp (CIP) inagwiritsidwa ntchito pa mipata ya mkuwa kuti golide apezekenso.

Njira za Flotation

Michira yamkuwa yoyandama idakonzedwa koyamba. Kupyolera mu kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Pambuyo pa kuyandama, ma tailings anali ndi mkuwa wa 48.50%, pakati pawo cyanide-mkuwa wokhoza kutuluka unali 0.12%.

CIP Cyanidation Njira

Ma tailings oyandamawo adasinthidwa ndi carbon-in-pulp cyanidation. Munjira iyi, Sodium cyanide kumwa kunali 3.1 kg/t. Kutsika kwa golide kukufika pa 74.71%. Chiwopsezo chonse cha golide pophatikiza kuyandama ndi leaching chinali 88.26%, ndipo kuchira kwa mkuwa kunali 62.16%.

Zotsatira ndi Ubwino

Kugwiritsa ntchito njira ya CIP cyanidation ku nsonga zamkuwa pamenepa wapeza zotsatira zodabwitsa. Choyamba, yapeza bwino golide kuchokera ku michira, ndikuwonjezera kupanga golide wonse mumgodi. Kachiwiri, ndondomekoyi yathandizanso kuti mkuwa ukhale wogwiritsidwa ntchito bwino, kuchepetsa kuwonongeka kwa zitsulo zamtengo wapatali. Kuphatikiza apo, poyerekeza ndi njira zochiritsira zachikhalidwe za michira, njirayi imakhala ndi mphamvu zochepa komanso ntchito yosavuta, yomwe imathandizira kuwongolera mtengo komanso kuteteza chilengedwe.

Kutsiliza

Kafukufukuyu akuwonetsa kuti njira ya carbon-in-pulp cyanidation ndi njira yotheka komanso yothandiza yopezera golide ku michira yamkuwa. Ndi kukhathamiritsa ndondomeko kuyenda ndi magawo, mlingo kuchira kwa zitsulo zamtengo wapatali akhoza kupititsidwa patsogolo bwino, kupereka umboni kwa migodi yofanana mu kubwezeretsa chuma ndi chitukuko zisathe.s
