The Framework Silicates. Quartz and feldspar are the two most abundant minerals in the continental crust. In fact, feldspar itself is the single most abundant mineral in the Earth's crust (see pie chart).The main feldspar minerals are potassium feldspar, (a.k.a. K-feldspar or K-spar) and the continuum of sodium- to calcium-rich plagioclase feldspars where …

Since they are both highly abundant crystals, there are plenty of variations. In many cases, though not always, feldspar is cloudy in appearance, while quartz is clear. If you held a piece of quartz to a light source, the light would shine through. If you do the same with feldspar, much less light would be seen.

Mica. Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.

Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 ( O'Meara, 1939 ). (1979) reported that HF creates a large difference in the minerals ...

Mica. Mica is a group of minerals. Mica is a sheet silicate and the sheets are easy to separate from each other because there are weak chemical bonds holding them together. This gives them perfect cleavage — the most characteristic feature of mica minerals. The term "mica" is, however, not easy to define. If we try to do it structurally ...

The latter is simple enough: add a drop of vinegar to both the desired crystals and the bedrock. If it fizzes then it reacts with acids. The most frequently treated specimens with acid are quartz specimens. You'll also find people treating feldspar and a few other non-reactive minerals this way.
