简介 | Methods for the extraction of cerium and/or thorium from metal compounds and solutions. A single step or two-step extraction method may be applied to selectively precipitate thorium and/or cerium as hydroxides under controlled pH conditions such that a substantially thorium-free and/or cerium-free rare earth element (REE) solution may be formed, such as for the subsequent separation of individual rare earth elements. |
