EXPRESSIONS OF INTEREST
Many customers of my products have requested some simple means to remove iron stone and magnetite from their concentrates.
I have some ideas to develop this product but first need to evaluate demand.
Could you please reply to this email with your thoughts.
example image of magnetite, sand and gold:-

Black magnetite was removed from a sample to recover white
sand and very fine gold particles.
You can observe a gold particle bottom right in petrii dish.
The small pin will give you same perspective as to the size fraction of the magnetite, sand and gold.
