Disclosed herein is a method of calcining particulate material, such as
kaolin. The method comprises providing a feed mixture comprising a
particulate material, such as hydrous kaolin, wherein at least a portion
of the particulate feed is coated with a liquid fuel. The method further
comprises heating the particulate feed mixture to calcine the particulate
feed and burn the liquid fuel to form a calcined product. The liquid fuel
coating can act as a secondary, indirect heat source for calcining. The
overall calcining temperatures and/or times can be reduced as a result of
adding the liquid fuel.
