Polycrystalline diamond tables and compacts and related methods

A polycrystalline diamond body produced by a process comprising:

• providing a polycrystalline diamond body including bonded diamond grains defining interstitial regions comprising at least one interstitial constituent disposed in the interstitial regions;
• at least partially leaching the polycrystalline diamond body with a leaching agent comprising a mixture having:
• a ratio of weight % hydrofluoric acid to weight % nitric acid of about 1.0 to about 2.4;
• and
• water in a concentration of about 50 weight % to about 85 weight %;
• producing an at least partially leached polycrystalline diamond body by removing at least a portion of the at least one interstitial constituent from the polycrystalline diamond body;
• and
• producing the at least partially leached polycrystalline diamond body such that a portion of the leaching agent and/or a byproduct of the leaching agent remains within the at least partially leached polycrystalline diamond body.
