A fairly simple chemical test for any tungsten ore is to grind to a fine powder and boil with concentrated hydrochloric acid for 15 minutes. If tungsten is present, the solution turns cloudy yellow and will turn blue if a piece of aluminum, zinc, solder, or tin is added. The yellow residue is soluble in ammonia.

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name.
