Grinding together quartz and feldspar grains in an agate mortar results in crushing the feldspar fraction due to its smaller hardness. Later sieving of the grinded mixture enables simple separation of both fractions. Then it is possible to save the feldspar fraction for later analyses instead of losing it as it occurs when using acid etching. Also,

feldspar and quartz as a function of pH adjusted by HF in addition of amine (200 g/ton). From the zeta potential-pH plot, point of zero charge (PZC) of quartz is pH 3.4. Nonetheless the PZC of feldspar cannot be observed due to its highly negative 6 2-) on Table 1. Grain counting of ground ROM feldspar; Feldspar (Feld.), Quartz (Qtz.),
Aug 10, 2019· Feldspars are hard minerals, all of them with a hardness of 6 on the Mohs scale. This lies between the hardness of a steel knife (5.5) and the hardness of quartz (7). In fact, feldspar is the standard for hardness 6 in the Mohs scale. Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff.
Apr 14, 2016· Feldspar Ore Grinding. The Rod Mill is standard for grinding feldspar ore, producing a granular product with a minimum of slime and fine size material. Grinding is always done to minus 20 mesh on account of market requirements. Feldspar this coarse will float very nicely and if liberation is obtained at this size no further grinding is necessary.
Mary McMahon Making up about 60% of the earth's crust, feldspar is a blanket term used for a large group of minerals.

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.
