Executive Summary
This section of the NI 43-101 Technical Report details the recovery methods employed at the Akbastau Uranium Mine, specifically focusing on the operations at the Karatau processing plant. The plant has been operating for several years and handles solutions from wellfields associated with the Akbastau No. 1 and No. 3 deposits. The process involves pumping uranium-rich pregnant solutions to a lined pond, followed by ion exchange using uranium-selective resin in columns.
The uranium is stripped from the resin using ammonium nitrate solution and precipitated using hydrogen peroxide. The resulting precipitate is dewatered, calcined, and packaged as yellowcake for shipment to refineries. Processing rates for Akbastau No. 1 ranged from 290 to 400 m³/h in 2011, while No. 3 increased to approximately 200 m³/h. Acid consumption data is also provided, averaging 21.6 kg/kg U for No. 1 and 49.7 kg/kg U for No. 3.
Processing Profile
- Ion Exchange: 50 m³ columns with uranium-selective resin.
- Desorption: 100 m³ columns using ammonium nitrate.
- Precipitation: Hydrogen peroxide.
- Finishing: Calcining and packaging.
