Abstract
This invention relates to a method of enhancing the leaching rate of a given material. The material is provided with a plurality of pores 16 each of which contain a gas, such as for example air, which is intermittantly exposed to the leaching solution 20 by the action of said leaching solution and acts to promote the rapid removal of the reaction product away from the core/leading solution interface 22.
