A method of processing a composite body comprising a super-hard structure and refractory metal material exposed proximate a boundary of the composite body, the refractory metal material comprising refractory metal. The method includes providing a basic corrosive agent, heating the corrosive agent to at least its melting point, contacting the composite body with the corrosive agent in the molten state and treating the composite body with the corrosive agent for a period of time to remove refractory metal material from the composite body. |
