1-8-2005 · The concept of leaching copper–gold ores using leach solutions which contain Cu(CN) 3 2− was investigated. Gold leaching occurs in air saturated Cu(CN) 3 2− solutions at a much slower rate than in free cyanide solutions. A similar gold leach rate is observed when copper is alloyed with the gold.

The copper will not only leach into the water (which copper poisoning is detrimental to human health), but the low TDS water will also cause "pitting" in the copper pipes that leads to pin-hole leaks. Okay, what does all of this have to do with RO water? RO water is low enough in TDS that it will cause copper leaching.
