Environmentally friendly leaching?
Most are not that good for environment. cyanide, thiourea, acid solvents. then we have mercury (very bad). Hmmm.

I think cyanide & thiourea heaps will decompose in sunlight. Thiourea is much more expensive that cyanide.

Wonder if anything will come of the black sands gold recovery that the company has been mentioning for a year now.
