Аннотация: Based on the comprehensive analysis of the crystal structure and chemical and phase composition of natural arsenopyrite of the "Panimba" deposit (Krasnoyarsk region), an analytical expression for calculating the impurity density in the structure of minerals like marcasite is received. Calculation of impurity density in crystal struПоказать полностьюcture of natural arsenopyrite of various chemical compounds is made and compared with the gold content in samples. As a result of theoretical calculations, the analysis of X-ray spectra, a chemical composition by electron-probe micro-analysis (EPMA), the dependence of the concentration of impurity atoms in the crystal structure from various chemical compound of arsenopyrite, and the gold content in the rock is established. The maximum content of gold corresponds to arsenopyrite in which ratio ((S + As)/Fe) >2. The chemical formula for content representation of the minerals like marcasite containing crystal structure atoms distinct from atoms of a forming matrix is offered.
