'Because gold powder is left'
Have you positively determined that it actually is gold powder and not wishfull thinking?
An alloy with gold consumed by nitric will leave behind brown or black powder, maybe even purple, but gold colored, no. Too small pieces to glitter. Or it was a really bad uneven alloy or gold plating, which makes no sense.
25% of gold with 75% silver leaves a brown skeleton behind, not shiny gold powder.
Then: is it Brass? IF SO: then it would dissolve in nitric yes, but is it in fact or is that another assumption?
Don't waste your time. Not all that glitters is gold. Sorry.
You could use it to smash things with.
