Thanks for the information, I was not aware of this ASL hydromet process, I will try to find more information. Please return my regards to Dr. Martins.
Cheers,
Dio

There are several technoligies still in the piloting or demonstration stage.

Agnico Eagle uses bitumen pads for clarifier ponds and waste-dumps when processing Au ore with high As content. And they are mighty proud of them. How prone they are to leakage? No one knows..
