Abstract: In this article are considered possibility of drawing into treatment off-balance copper ore for the purpose after extraction from their valuable components. On the basis of learning chemical and mineralogical compounds off-balance ores are defined, what optimal ways their treatment are piles leaching. Shown results by sulfuric acid leaching minerals of copper considered in consist of off-balance ores and defined, what optimal conditions sulfuric acid leaching are concentration sulfuric acid 50-75 g/l, duration 15 days, degree of extraction oxide copper from solution is 98,5-99%, sulfuric copper is 5,6%
Keywords: Off-balance copper ores, Harmful influence, Leaching process, Heap leaching organization (HL), Iron (III) sulfate solution, Copper recovery degree, Dynamic equilibrium of leaching process.
