Which is the only liquid in which gold is dissolved?
Submitted by: AdministratorSince gold is very a noble metal, it does not dissolve in conventional solvents used to leach. Gold cannot be easily converted to Au2+ cations, so in practice, it becomes dissolved in the form of complex cations Au((CN)2)-, using the alkaline cyanide solutions like sodium cyanide, indeed in the presence of oxygen as oxidant(usually air agitation is used).
