The deposit of copper was explored with drilling from the surface. Research has established relatively low, evenly distributed contents of copper and gold. An experimental study of the leaching process of flotation tailings is done in the aim of valorization the present copper. The degree of copper leaching was about 60%, which is exactly the participation of oxide copper forms regarding to the total copper content of the flotation tailings.
