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.

Abstract: Process for precipitating a carbonate or (oxy)hydroxide comprising nickel from an aqueous solution of a nickel salt wherein such process is carried out in a vessel comprising (A) a vessel body, (B) one or more elements that control the hydraulic flow of the slurry formed during the precipitation and that induce a loop-type circulation flow, and (C) a stirrer whose stirrer element is in the vessel but located separately from the element(s) (B).

Abstract: Disclosed herein is a process for precipitating a mixed hydroxide of TM where TM includes Ni, at least one of Co and Mn, and, optionally, one of Al, Mg, Zr or Ti from an aqueous solution of salts of such transition metals or of Al or of Mg. The process is carried out in a stirred vessel and includes the step of introducing a 10 to 40% by weight aqueous solution of ammonia and an aqueous solution of transition metal salts through at least two inlets into the stirred vessel. An aqueous solution of alkali metal hydroxide is added separately from the at least two inlets.
