About the program
Relevance

Kazakhstan has generated 4 billion tons of waste of mining waste. The mining wastes collected in tailings management facilities and their safety and environmental impact are now under consideration. In 2023, the United Nations Economic Commission for Europe (UNECE) started an initiative in Central Asia to promote an understanding of the risks associated with tailings and raise awareness of tailings as a hazardous activity. UNECE has created a map of mining tailings in Kazakhstan. The 2024-2026 plan of UNECE includes the improvement of shared understanding and risk management across countries on mining waste. However, the literature review revealed no attempt to study CO2 mineral trapping using mining waste rocks in Post-Soviet countries, and this project will pioneer CO2 mineral trapping in the CIS.

Goals
  • Characterization of mining waste rocks in Kazakhstan
  • Development of feasible mineral carbonation technology using Kazakhstan mining waste rocks
  • Novel Carbonation development with heavy metal detoxification
Expected Results

By the end of the program, we aim to achieve:

Detailed characterization of Kazakhstan mining waste for using modern physicochemical research methods which include radiography, electron microscopy, thermogravimetry, IR spectroscopy, pH-metry, etc.

Study of the potential for technological application of mining waste rocks in Kazakhstan which includes nemalite-serpentinite minerals.

Development of feasible and effective mineral carbonation technologies in Kazakhstan.

Determination of influence of grinding, thermal and mechanical activation of minerals on the processes: transfer and injection of CO2 into minerals (rocks) (in-situ, direct carbonization processes) and carbonization in a reactor using the pH fluctuation method (ex-situ, indirect carbonization processes), optimization using experimental design to obtain better process results.

Achievements (as mid of 2025)
