METHOD FOR PURIFYING LITHIUM-CONTAINING WASTE WATERS DURING THE CONTINUOUS MANUFACTURE OF LITHIUM TRANSITION METAL PHOSPHATES |
摘要 |
The present invention relates to a method for continuously producing lithium transition metal phosphates of the formula LiMPO4, comprising the steps of: a) providing an aqueous reactive mixture containing LiOH, H3PO4, and a transition metal sulfate; b) reacting the reactive mixture to form a lithium transition metal phosphate; c) separating the solid lithium transition metal phosphate from the soluble part of the reactive mixture; d) subjecting the soluble part (diluate) to electrodialysis; e) isolating the part of the electrodialysate which contains an aqueous LiOH solution.
