Mokhoa oa ho leaching oa Cyanide

Ho tlosa cyanide ka hara oli ke mokhoa o tlwaelehileng wa ho tjheka le ho hlwekisa kgauta. Sodium cyanide (NaCN) e sebedisetswa ho qhibilihisa kgauta ho tswa lerung. Ha ho na le oksijene, Sodium Cyanide e arabela le kgauta ho etsa di-complex tsa cyanide tsa kgauta tse qhibilihang. Mohlala, ha ho qhibilihisa ka hara oli, ditharollo tsa cyanide di fafatswa hodima diqubu tsa oli e sithabetseng e hasaneng hodima di-pad tse kgolo tsa pokello. Tharollo ya cyanide e phunyeletsa ka hara oli, e qhibilihisa kgauta, ebe e bokellwa ka hara tharollo. Ha ho qhibilihisa ka hara tanka, e etswang dibakeng tse laolwang haholo jwalo ka ditanka tse kgolo, tshebetso e tshwana, empa e hlahisa masala e le sehlahiswa sa ditshila.
