Hi Durockguy,
Could you tell me a bit more about this please.
Is it a wet filter, or a dry filter ?
Why do you want to remove metal particles ?
Is it fine grained sand ?
Is it because the sand is used in ceramics
and metals discolour the result ?
Are you going to make a substantial machine to
handle large quantities, or do you just want a
modest unit to supply small amounts ?
You realise that a magnet will not attract most
metals, in practice only one type. But it will
also pull a bit on cobalt i think, not that
theres much of that lying about.
Could you say what metals might be in the sand,
and roughly the sizes of the particles ?
Cheers, John
