Hint: to highlight K-feldspar, switch to a medium or low magnification objective (usually 4 or 10X works well), mostly close the substage iris, and raise the stage slightly (yes, raise). Though the image will be somewhat out of focus, the low index K-feldspar grains will be surrounded by bright Becke lines just inside the grain boundaries.

The graphite/ore-rock slurry is then fed to froth floatation cells. Froth floatation is a method of beneficiation which relies on the differences between the surface chemistry of the country rock and the mineral being extracted, in this case graphite flake. In the cell the ore is mixed with water and "floatation agents".

The variations in structure result in minerals with different morphologies. Indeed most phyllosilicate minerals have a platy morphology, although the variations in mineral structure affect the degree of layering, irregularities in stacking behaviour, crystallinity and cleavage of the minerals (Deer et al., 1992).

Talc is a platy mineral which is commonly used in TPO formulations in order to increase the modulus, strength, and HDT of polyolefins. Although talc is not as reinforcing as GF, it enables good surface finish and dimensional stability to the parts, both of which could be an issue with GF filled TPO systems.
