Two formulas have been derived by the author for assessment of kernel-electron interaction energy in minerals: the first one represents summing of ionization potentials developed in atomic kernels formation and atomization energy, while the second one (based on Fersman's approach) defines this energy as a sum of atomic kernels and binding electrons energy coefficients. The author of this paper suggests and demonstrates a method for assessment of mineral atomization energy with calculation error not exceeding 2 % by the use of both above mentioned formulas. This method appears to be especially advantageous for calculation of atomization energy in metal bonds possessing minerals (such as pyrite, galena, troilite, molibdenite, chalcocite etc.) which are principal minerals of the corresponding metallic ores. The practical application of this method consists in that by the use of atomization energy parameters found after calculation there arises possibility to explain and foretell a wide specter of physical and chemical properties (including ore processing amenability) of various minerals. The corresponding formulas for assessment of mineral properties are given in the reference (Zuyev, 2005) cited in the paper. It is to be emphasized that the calculation methods suggested provide only tentative theoretical estimations of substances atomization energy which is to be specified more precisely after the experimental data have been available.
