Abstract
The invention provides a method of steam stripping an inorganic powder by contacting the inorganic powder with a silylating agent to form a silylated mixture which is pneumatically transported and contacted with steam to form a vaporous stream. This vaporous stream is then transported to a separation stage and the volatile materials are separated from the inorganic powder.
