Cyanidation Leaching

Ho ntsha ha cyanidation ke motheo wa tshebetso. Majwe a kgauta, ka mora ho silwa, ho silwa le ho ntshwa, a kopanngwa le tharollo ya cyanide . Tlasa maemo a loketseng a pH, mocheso le phepelo ya oksijene, kgauta e ka hara ore e arabela le di-ion tsa cyanide ho etsa di-complex tsa cyanide tsa kgauta tse qhibilihang. Karabelo ya dikhemikhale e ka hlaloswa ka tsela e bonolo tjena:

Karabelo ena e lumella khauta hore e qhibililoe ho tloha matrix a ore ho ea tharollong, ho e arola ho liminerale tsa gangue.
