How to Identify Tungsten Ore-2

5.Measure the crystal's specific gravity -- its weight compared with its volume. It is a good way to identify minerals. The specific gravity of wolframite is 7.40 grams per cubic centimeter. The specific gravity of scheelite is 6.01 grams per cubic centimeter. If you do not obtain access to such equipment, heft the sample in your palm. Both minerals should feel quite heavy for their sizes.

6.Place a magnet on a mineral thought to be wolframite. Wolframite includes iron, making it slightly metallic.

7.Shine a UV light on a mineral considered to be scheelite. Scheelite fluoresces bright white-blue under a UV light if it is very pure, and creamy yellow if it contains molybdenum.

8.Examine the other minerals that may have formed on your specimen. Wolframite often develops with topaz and quartz. Scheelite often develops with tremolite, tourmaline, topaz, vesuvianite, cassiterite, fluorite, diopside and apatite. What’s more, wolframite and scheelite are usually found together.
