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 mu cyanide solution.

KHABONI MU NDANDANDA 

CIC imagwiritsidwa ntchito kwambiri pobweza golide kuchokera ku ntchito zochotsa miyala, njira zomwe yankho la Sodium Cyanide limadutsa mu "mulu" wa miyala yophwanyika ndi yosakanikirana, zomwe zimapangitsa kuti golide alowe mu yankho. Yankho lokhala ndi golide limapopedwa ku mipiringidzo yambiri yothira madzi yokhala ndi Carbon yogwira ntchito . Kuchotsa miyala motsatira ma CIC circuits ndi njira yabwino kwambiri yobweza golide kuchokera ku malo otsika 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 pakhale matope a miyala ndi madzi otchedwa pulp. Kenako pulp imapopedwa kupita ku ziwiya zotulutsira golide zomwe zimagwedezeka ndi mpweya, komwe golide amatulutsidwa kuchokera mu miyala pogwiritsa ntchito sodium cyanide solution. pulp imasamutsidwira ku matanki angapo a adsorber okhala ndi Activated Carbon , omwe amasakanikirana ndi pulp yotulutsidwa ndi madzi ndikuyenda motsutsana ndi pulp m'matanki angapo. Carbon yotulutsidwa ndi golide imalekanitsidwa ndi pulp ndi chophimba cha mesh 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.
