Tungsten Metallurgy

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.
