In this form it is not concentrated enough to use as an ore to produce iron metal. However, it is possible to concentrate the magnetite grains from the silica sand using gravity separation, as magnetite is heavier than silica sand. So, I made a sluice box from a spare roof tile I made in an earlier video. The curved tile acts as a chute and grooves were carved into the concave surface perpendicular to it's length. When sand was put into the sluice and water was run over it, the heavier magnetite got trapped in the grooves and most of the lighter sand was washed away. The trapped iron sand was then tipped into a collection pot. This sand was then sluiced a second time to concentrate it further. From experiment, it was found that sluicing twice yields the best result for effort, sluicing a
