I know I asked what was a silly question about the chemicals and got the replies expected. It is interesting what people do with different chemicals and is why I asked. I go through a bit of liquid pool chlorine in the cleaning work I do.
The chemicals are used to refine precious metals most of what I know about metallurgy came from Hokes Refining Precious Metals Wastes.

Ammonium chloride is what makes the unique flavor in Black Licorice, it's used in certain baked goods to add crispness, also used to add patina to copper, used as a soldering flux.
The ammonium chloride is inexpensive to purchase however quality is questionable. And I need a chemically pure product.
To make it chemically pure the ammonia chloride crystals will be re-hydrated then once again the liquid evaporated then cooled to allow the crystals to reform any liquids left over discarded. The procedure is carried out twice more.
Ammonium chloride is then used to precipitate platinum from a multi species liquor containing nickle, platinum, palladium, rhodium with perhaps a bit of gold ions in solution.
There's more than one way to skin a cat, ammonium chloride is one of many reagents selective to platinum.
