There is no major problem with acid mine water discharge from sulphide mines in Canada that I know of. I can think of no river or Lake which is terribly damaged from acid mine wastes or tailings pond wastes. I could be wrong here as I have not given it much in depth study and I am going on having lived near mines most of my life in many areas of Canada. Even in the Sudbury area you would expect that the lakes in the area would be laid waste by tailings drainage but this is not the case. The damage there was caused by ancient smelters putting sulfur dioxide gases into the air. This can now be recovered almost 100% by catalytic conversion.

Some Iron oxide mines had a real problem with acid tails. One could lime the tails and prevent the metals from staying in solution. This was not always done. I have access to a technology that can recover 100% of the dissolved metals from mine waters at pennies per ton. As a matter of fact it can desalinate water cheaper than any other method. It is brand new technology and as far as I know not in place at any mines. De-cyanidation could be achieved by this method too. It is very exciting tech as it promises to be able to clean up and permit many situations to a higher standard and much cheaper than previously thought possible.
