Mokhoa oa ho leaching oa Cyanide

Cyanide leaching ke mokhoa o tloaelehileng oa ho rafa le ho hloekisa khauta. Sodium cyanide (NaCN) e sebelisetsoa ho qhaqha khauta ho tloha ore. Ka boteng ba oksijene, Sodium cyanide e kopana le khauta ho etsa metsoako ea khauta e qhibilihang ea cyanide. Mohlala, ha qubu ea leaching, metsoako ea cyanide e fafatsoa holim'a liqubu tsa ore e sithabetseng e phatlalalitsoeng ho pholletsa le lipampiri tse kholo tsa pokello. Tharollo ea cyanide e phunyeletsa ka har'a qubu ea ore, e qhibilihisa khauta, ebe e bokelloa ka tharollo. Ka tanka leaching, e etsoang libakeng tse laoloang haholoanyane joaloka litanka tse kholo, mokhoa ona o tšoana, empa o hlahisa mehatla e le sehlahisoa sa litšila.
