Liquefying Slag with CDE 2

[Joeyboots]

Has anyone ever used the CDE 2 Leeching process? There is a website Rocky Ledge Mining that has this process. Is it as effective as described? Anyone out there using Aqua Regia or Nitric Acid to recover precious metals who knows of any package setups for this?

Hello Joe

read up on goldrefiningforum.com for the most info on leaching and what people are trying.

We have used or tried many things. At the moment we are concentrating on bio leaching with microbes. This has the promise of not using near as much acid to treat the material in the initial stages.
