Abstract

A method of processing a polycrystalline diamond (PCD) material having a non-diamond phase comprising a diamond catalyst/solvent material is disclosed which comprises leaching an amount of the diamond catalyst/solvent from the PCD material by exposing at least a portion of the PCD material to a leaching mixture. The leaching mixture comprises hydrochloric acid and one or more additional mineral acids, the molar concentration of the hydrochloric acid being greater than the molar concentration of the one or more additional mineral acids in the leaching mixture. The additional acids may be sulphuric acid, phosphoric acid, perchloric acid or nitric acid. The leaching may be carried out by heating the leaching mixture to a temperature at or grater to the boiling temperature of the leaching mixture.
