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.
Magnetite may form a yellow-brown rust coating if washed or kept in a moist area. If a specimen is washed, it should be dried to prevent rusting. Rust can easily be removed by soaking the Magnetite in a rust-removing solvent such as Iron Out. The mineral Hematite is known to form pseudomorphs over Magnetite.
Aug 07, 2011· *Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the ore.
