The experiments on the sulfuric acid leaching of main ore-bearing rocks of gold deposit Lyubov (Zabaikalsky Krai) were carried out for the determination of mobile chemical elements in acidic landscapes weathering processes. The chemical composition of ore samples, major and minor minerals have been determined. The composition of the ore and rock-forming minerals were studied by X-ray diffraction and chemical analyses and electron microscopy. According to the results of the experiments has been revealed a group of mobile chalcophile elements (Pb, Zn, Cu, Cd), V group elements (As, Sb, Bi) associated with sulfide minerals and a group of rare and trace elements. It has been determined that with contents below clarkes abundance the lanthanides, cesium, chromium, germanium are rapidly moved in acidic solution.
