Njira Zokometsera ndi Mpweya Wogwiritsidwa Ntchito

Njira zosiyanasiyana zochotsera golide zimagwiritsidwa ntchito potulutsa golide kuchokera ku miyala yaiwisi yophwanyika. Njirazi zimapangitsa kuti golideyo apezeke kuti atulutsidwe m'madzi. cyanide Yankho. 

KHABONI MU NDANDANDA 

CIC imagwiritsidwa ntchito kwambiri pobweza golide kuchokera ku ntchito zochotsa golide m'matanthwe, njira zomwe Sodium Cyanide Madzi oyeretsera amalowa mu "mulu" wa miyala yophwanyika ndi yosakanikirana, zomwe zimapangitsa kuti golide alowe mumadzi oyeretsera. Madzi oyeretsera okhala ndi golide amapopedwa ku mizere yambiri yoyatsira yomwe ili ndi mphamvu yogwira ntchito. CarbonKuchotsa miyala mu heap leaching kutsatiridwa ndi ma CIC circuits ndi njira yabwino kwambiri yopezera golide kuchokera ku zinthu zotsalira pamwamba ndi miyala yotayira chifukwa cha ndalama zake zochepa komanso ndalama zogwirira ntchito. 

KHABONI MU PULP

Mu ntchito za CIP, miyala yodulidwa imaphwanyidwa ndikusakanizidwa ndi madzi ndi zokhuthala, zomwe zimapangitsa kuti miyala ndi madzi zikhale ngati pulp. Kenako pulp imapopedwa kupita ku ziwiya zotulutsira golide zomwe zimagwedezeka ndi mpweya, komwe golide amatulutsidwa kuchokera mu miyala pogwiritsa ntchito njira ya sodium cyanide yankho. Zamkati zimasamutsidwira ku matanki angapo a adsorber okhala ndi Carbon Woyendetsa, yomwe imasakanikirana ndi pulp yotuluka madzi ndipo imapita motsutsana ndi pulp m'matanki angapo. Mpweya wopangidwa ndi golide umalekanitsidwa ndi pulp ndi chophimba cha maukonde chomwe chimatseka carbon kuti isadutse, pomwe tinthu tating'onoting'ono ta pulp timasefedwa. 

Kaboni-Mu-Kutuluka 

Ntchito za CIL zimafanana kwambiri ndi CIP, koma mpweya wopangidwa umawonjezedwa mwachindunji m'mitsempha yomwe imachitika cyanidation. CIL ndi njira yopindulitsa kwambiri pamene miyala ili ndi zinthu zambiri za carbonaceous. Mpweya wachilengedwe umapikisana ndi mpweya wopangidwa kuti utenge golide mu njira yotchedwa "preg robbing," yomwe imayambitsa kutayika kwa golide. Chifukwa chake, mu CIL, njira ya cyanidation imachitika nthawi imodzi ndi madzi pa mpweya wopangidwa kuti ugwire ntchito, womwe umakhudzana mwachindunji ndi zamkati mu yankho la cyanide. Njira ya CIL imachepetsa nthawi yomwe golide wopangidwa kuti ugwire ntchito ndi mpweya wotsutsana ndi kaboni wochokera ku miyala.
