Non-thermal process for extracting rare earths from

1998-1-1  The third step is leaching of the washed powder with HCl or H 2 SO 4 solutions at room temperature, extracting the rare earths. The extractive yield of rare earths is improved with an increase in milling time. Furthermore, HCl solution is superior to H 2 SO 4 as a leaching medium. In the present work, more than 90% of the rare earths in the bastnaesite sample was extracted by dilute HCl solution from
