Executive Summary
The Karatau Uranium Mine operates an established process plant that has been expanded over time to increase throughput and add calcining and packaging circuits. The facility processes uranium-rich solutions pumped from wellfields, including solutions from the adjacent Akbastau Uranium Mine. The plant utilizes ion exchange columns loaded with uranium-selective resin to adsorb uranium from the pregnant solutions, targeting a resin loading of 20 kg U/m3.
Following adsorption, the uranium-bearing resin is transferred to desorption columns where uranium is stripped using ammonium nitrate solution. The resulting strip solution is precipitated using hydrogen peroxide, dewatered, and calcined before packaging in drums for shipment. The process recovery of uranium delivered to the plant is forecast to average approximately 97.5%, a performance level currently achievable based on operating experience. The plant has a capacity of 3,000 t U per annum.
