About Salt
Worldwide, table salts are refined to the point that they are almost Sodium Chloride. All trace elements and minerals, which natural unrefined sea salt should contain, have been washed out in the refining process. Chemicals are then added to keep salt free-flowing and dry. Some salt pans bleach their salt if it is of poor quality.

Recovery of gold from PGC.
PGC is the most common gold plating salt. It is used in both acid gold baths (pH usually about 4.3 - 6.0) and cyanide gold baths (pH of usually 10.3 or higher). Most all gold plating on electronics is done in acid baths containing PGC, which also often contain a little nickel or cobalt as a hardener.
