Froth flotation of scheelite has regained new focus since the 2010s and research regarding floatability and reagents has made great progress over the years. The main objective was and remains the selective flotation of scheelite from other calcium bearing minerals, in particular calcite, fluorite and apatite.
In addition, three distinct generations of scheelite and two types of wolframite can be clearly distinguished. Type 1 wolframite has a semiautomorphic grain or brecciated vein structure with a high heavy rare earth element content and an obvious negative Eu anomaly.
Scheelite, is an important ore of tungsten, but not on a worldwide basis. Most non US ore is derived from wolframite WO 4, whereas scheelite is the dominant source of tungsten ore in the US.
