Exploration studies in Uzbekistan revealed one graphite deposit (Taskazgan) and about 25 sites with varying perspective degree. In order to obtain the graphite for refractory industry uses insufficiently known Rupat, Zauchak and Zahchahona sites were studied. According to the research, Zahchahona site can be classified as a medium-sized field; the refined graphite content in the ore deposit is 3 to 15 %, which meets the requirements of the industry for this type of raw material. Graphite was refined by flotation and leaching process, brought to grade of 75 % carbon.
