| Abstract: | The conditions and the selection of the optimization process that rare earths are extracted by the ammonium hydrocarbonate precipitation are studied. The results indicate that rare earths extracted by the ammonium hydrocarbonate precipitation method obtain mixed oxidized rare earths products content (RE2O3%)over national output standard (92%). |
