Hi,

The usual method of filtering mercury is to use a
small folded filter
paper, with a very small hole torn in the point of the cone. The
mercury will run through the small hole, but most of the rubbish, which
floats on the top, will stay behind. You usually need to do this a
couple of times.
I just rang my brother, who used to use mercury a lot when assaying
metal ores, and that's what they used to do to clean up the mercury
after use. They used to run it through concentrated hydrochloric acid
first to dissolve any ore residue.
