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.

Process A process for removing water from a particulate material selected from the group consisting of (oxy) hydroxides and carbonates containing at least one transition metal selected from the group consisting of nickel, cobalt, and at least one metal other than nickel, said process comprising 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 the at least one particulate material through the rotary kiln together with a flow of a gas, wherein an average residence time of the particulate material is in the range of from 30 minutes to 5 hours and wherein a residual moisture of the resultant product is in the range of from 50 ppm to 1.5% by weight.
