Fundamental bases of the organochemical leaching of the metals coloured, rare-earth and precious from mineral natural and second technogenic raw material

Investigation of the mechanisms of bioleaching minerals extractant can use their patterns for selective removal of target chemical elements. The estimation of possibility of organic acids to the reactions of lixiviating was executed after classic thermodynamics parameters – the change of energy of Gibbs (∆G0f), enthalpy of formation of reaction products (∆H0f), entropy of reaction (∆S0f), energy of activating of lixiviating process (Er), constant of equilibrium of reaction (Kr) and energy of crystalline grate of having a special purpose mineral (Ucryst).
