Gold & Platinum Refining Metal Cleaning
When refining using the aqua regia method, it is necessary to add urea before the gold is precipitated. Typically, especially with nitric-acid-based aqua regia, there are free nitrogen ions in solution. This can cause some gold to redissolve after it has precipitated. Adding urea neutralizes free nitrogen ions and prevents gold from redissolving.
