AQUA REGIA RECYCLING

Aqua regia is a potent acid made by mixing one part aqua fortis with three parts acidum salis. Alchemists and industrialists alike covet the highly corrosive substance for its ability to dissolve gold, making it a vital part of the gold supply chain.

Here, the aqua regia has bonded to a gold atom from some freshly excavated ore. This binding needs to be undone to retrieve the gold and reuse the aqua regia. Optimizing this process means remaining competitive in the gold industry.
