Hello: I have some silver powder that is contaminated with stone
(came from mortar and pestle, marble or something similiar). Can
anyone tell me how to clean the silver powder? Any help will be
appreciated.

G’day;If what you have with your silver dust is really marble or
natural chalk, then almost any acid other than nitric will dissolve
the marble and leave the silver alone. Nitric acid will dissolve
the silver too.
