 The fluorine reaction has the advantage that, since fluorine is more [[electronegative]] than oxygen, fluorine will displace oxygen from any composition of lunar rock.  Hence, in principle, the process chemistry does not require finding any particular mineral source, or beneficiation of the soil to enhance the content of a particular mineral.

 Recently [[Geoffrey A. Landis]] of NASA's [[John Glenn Research Center]] has proposed that the use of the fluoride reaction sequence could be a method by which processing lunar materials could be done to produce [[silicon]] as well as [[iron]], [[aluminum]], and the basic oxide components of [[glass]], which could be used in manufacturing, as well as producing oxygen.  In his proposal the fluorine is brought to the moon in the form of [[potassium fluoride]], and is liberated from the salt by electrolysis in a eutectic salt melt. [[Tetrafluorosilane]] produced by this process is reduced to silicon by a [[plasma reduction]] stage; and the fluorine salts are reduced to metals by reaction with metallic [[potassium]] to form potassium fluoride, [[K]][[F]], the original starting material). Fluorine is recovered from residual [[Mg]][[F]] and [[Ca]][[F]]<sub>2</sub> by reaction with [[K]]<sub>2</sub>[[O]].

	While a far more complex reaction sequence, the primary benefit of the HF acid leach system is much lower reaction temperatures. Lower temperature requirements result in a lower energy input and power savings which can be used for other life support functions.
