My understanding of the process is that no chemicals are really added into the process. Everything that we have in the tailings ponds, all the heavy metals, everything that we see in the tailings ponds, was actually naturally occurring. It either got pumped in through the process.... It was naturally occurring in the Athabasca River, or it was naturally occurring in the soils.
Is that true, or is there a chemical solvent, a diluent or something like that, that's added into the process we should know about?
