Abstract: Disclosed herein is a process for removing water from a particulate material selected from (oxy)hydroxides and carbonates containing at least one of nickel cobalt, and at least one metal other than nickel. The process includes the step of introducing at least one particulate material with a water content in the range of from 1 to 30% by weight, referring to said particulate material, into a rotary kiln with external heating elements and moving it through the rotary kiln together with a flow of a gas. The residual moisture of the resultant product is in the range of from 50 ppm to 1.5% by weight.
