1. Process for preparing nickel hydroxide by alkaline precipitation from nickel salt solutions in the presence of complexing agents, wherein the nickel salt solutions are introduced into a mother liquor via several spatially separated inlets in such a way that precipitation takes place in at least two different locations, with different precipitation kinetics, in the mother liquor and the mother liquor is stirred prior to agglomeration of precipitated primary crystals.
