Anyone know about CDE2, CDE3 leaches?

[apkmetal]

I came across a company called Rocky Ledge Mining Supply. They sell a CDE2 and CDE3 gold leach that can supposedly be used with all ores. They also offer an Citric Wash pre-leach and Iron Oxidizer.

There CDE5 solvent leach sounds like Butyl Diglymine.

Anyone have any experience or information on these items?
