Integrated anti-radiation and antiseepage shield wash at the tailings pond at Plant GMZ 1 of the Navoi Mining and Metallurgical Combinat

The article presents the research results on disposal of uranium mill waste at the tailings pond of a mining and metallurgical plant. The tailings pond is the largest accumulation of radioactive material in Central Asia [1]. The project provided mechanical disposal of uranium mill tailings using material from an open pit mine. It was proposed to use the hydraulic wash-in method bury gold ore processing waste. Suing the waste, an anti-radiation shield was washed by small layers with total and sufficient thickness of 2 m. As a result of disposal of uranium mill tailings by creation of the integrated (anti-radiation and anti-seepage) shield made of gold ore processing waste, background radiation was abated, seepage of liquid tailings in ground water was reduced and the cost of disposal was cut down by 4 times. From the implemented research and calculation, at the thickness of the inert coating of uranium mill tailings more than 1 m, the gamma radiation will be mainly governed by radiation of the tailings and by space radiation, and it will be within the range up to 1 mSv/h allowable by the Sanitary Code. It is also found that in ground water in the zone beyond the tailings pond boundary, the cyanide concentration is not higher than the maximum allowable value while the volumetric activity of radionuclides is much weaker than allowable concentrations.

Keywords: Tailings pond, anti-radiation and anti-seepage shield, radiation, permeation, slurry, slurry pipeline, wash-in, disposal.
