· Spread the sand, salt and iron mixture on a flat surface. Wrap the magnet in the paper towel. Use the magnet to remove the iron by pulling it across the surface of the mixture. The filings stick to the magnet while the sand and salt are left behind. Remove the paper towel from the magnet to collect the filings. Use warm water to dissolve the salt.
The authentic discovery of element 61 had to await the development of a new separation technique, ion-exchange chromatography, and work on the atomic bomb during World War II. Finally, in 1947, Marinsky, Glendenin and Coryell announced the discovery of the unstable element 61, which they named promethium after the Titan who stole fire from the ...

Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.
