Coal fly ash samples from different power plants of India have been collected and studied for their rare earth content and recovery. These samples were dissolved in nitric acid by (1) acid-digestion method and (2) by fusion with NaOH + NaNO 3 mixture at 600 °C followed by successive hydrothermal treatment of the fused mass. The analysis of major and trace elements was done by ICP-AES.All the ...
