Magnetite is known to be highly magnetic, and this will help in the separation process. Hematite on the other hand is only slightly magnetic. It does not hold near the attraction to a magnet that magnetite does, but will still draw to a magnet if it is extremely strong. This will be to the miner's advantage further in the separation process.

Gold normally exhibits a chemical valence of one or three. Gold is the "noblest" of the noble metals (gold, platinum, palladium, and rhodium), so termed because of their inertness, or reluctance to enter into chemical reactions. Gold will not react with common acids but is attacked by a three-to-one mixture of hydrochloric and nitric acids.
