[QUOTE="grubstake, post: 361013, member: 4012"] It's a bit laborious, but if you put a magnet inside a plastic bag, you should be able to selectively pick up magnetite on the outside of the bag. Then hold the bag over a bucket while removing the magnet, to release the magnetite into the bucket. Repeat the process until you get enough magnetite. If there's contamination with white limestone sand, washing in a gold pan will concentrate the magnetite component. [/QUOTE]
