Scheelite

Scheelite is the mineral form of calcium tungstate, CaWO₄. It is one of two main ores of tungsten. The other is wolframite (ferberite and hübnerite).^[1]

Scheelite was historically called "tungsten". Carl Wilhelm Scheele discovered a new mineral acid could be made from this mineral, and named it "tungstic acid". Scheele believed this acid contained a new chemical element, but could not make it.^[2] After the element was discovered and named "tungsten", the mineral was renamed after Scheele.^[3]
