Abstract: The present invention relates to a method for the refining of a material comprising iron oxide and at least one contaminant selected from the group consisting of halogen and sulfur by reducing the content of the at least one contaminant, characterized by calcining the material in the presence of a gas containing water vapor. The invention also relates to a refined material obtainable from such a method and the use for catalyst production.

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.
