This method only works to search for negative gravitational mass
mirror matter that is lightly bound to ordinary matter. Ordinary
mirror matter can only be concentrated using a high speed centrifuge
to separate the mirror matter from the ordinary matter to which it
binds. Folks on a tight budget like me would prefer to use the cheap
medical style centrifuges available on ebay, so this method might
provide an alternative to panning for gold for recreation. A tiny
amount of negative gravitational mirror matter could be worth a
million times its weight in gold.
So, here is a possibly useful method. Chemically digest the material
in question. (An alternative method might involve pulverizing it and
placing in liquid with density such that the normal variety of the
material achieves neutral buoyancy or even very slightly positive
bouyancy.) A good material to start with might be sea water because
it avoids this step entirely and the stuff should be found near the
surface. The ocean is a great collector for mirror matter cosmic
rays. The negative gravitational mirror matter containing stuff
should be right on the surface.
Let the solution sit in a holding tank and then take the top half and
reject the bottom half. This is gravimetric separation so the top
half should tend to contain the desired mirror matter. Place the
remaining material in a centrifuge. This is inertial separation so
the mirror matter should end up in the bottom of the tube. Reject
the top half of the contents of the centrifuge tube. This completes
one stage of separation, Stage 1.
The stages can be repeated as often as necessary. The material
remaining from Stage N is fed into Stage N+1. Two stage N runs may be
necessary for one stage N+1 run.
If it is known mirror matter is actually in the solution, or once
(and if) it ever happens that enough material is separated at stage N
to show its presence thermally, then the reject material from stage N
can be fed back into stage N-1, mixed with material from stage N-2 to
make the input for stage N-1.
The process can stop at a stage N where the temperature drop for a
fixed mass of material output from stage N is the same as the for
the output from the prior stage, in other words when the separation
process no longer improves the concentration of mirror matter.
For commercial purposes a high speed centrifuge is a much better
method because the separation can occur in one stage, as suggested by

Universe, Universal Publishers, ISBN 158112645X
However, this his method does not search for negative gravitational
mirror matter. Finding either kind would be like winning a lottery.
