Procedure

422.4 g citric acid were dissolved in 600 ml water, heated to about 80° C., and reacted at a temperature of 100° C. with a mash of 315.2 g cobalt (II) hydroxide carbonate in 1400 ml water, which was added slowly. After filtration and spray drying, 704.4 g cobalt citrate of a cobalt content of 24.8% by weight was obtained, which is about equivalent to 99% by weight of the cobalt feed.
