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.

Gneiss ("nice") is a rock of great variety with large mineral grains arranged in wide bands. It means a type of rock texture, not a composition. This type of metamorphic was created by regional metamorphism, in which a sedimentary or igneous rock has been deeply buried and subjected to high temperatures and pressures.

TALC Talc is a mineral composed of hydrated magnesium silicate. Its chemical formula is Mg3Si4O10(OH)2. It is very soft and can be cut with a knife. Talc is insoluble in water, but it is slightly soluble in dilute acids. • Talc is a very soft mineral that is colorless when pure and appears white in powder form.

Qualified talc ...

platy minerals that develops a Figure 4.1. Effects of stress (pressure) on platy minerals in a shale. Mica minerals are first aligned perpendicular to the direction of pressure, and then grow larger with increasing grade of metamorphism. Eventually, complete mineral separation occurs giving the diagnostic layering found in gneiss.

The loss of water from hydrated minerals can effect its mechanical properties and volume. The transition from gypsum to anhydrite, for example: CaSO 4.2H 2 O --> CaSO 4 + 2H 2 O Similarly when a non-hydrated mineral accepts water: Fe 2 O 3 (hematite) + 3H 2 O - …

Schist form within the P-T field of upper low-grade to medium-grade metamorphism. The increase in degree of metamorphism is accompanied by an increase in the size of platy crystals. The platy minerals in slate are too small to be seen. In phyllite, the flakes have grown larger as evidenced by an increase in luster.

Most mineral processing operations are conducted with water as the medium. This is called wet process against dry process, which is performed without wate r. The reason for this is mainly for the advantage or the necessity of the separation process. Normally processing of a ton of ores, several tons of water is needed, even if part of the water

The products from AG or SAG mills typically feed secondary grinding mills with particles that range in size from 5 cm down to below 100 microns (0.1 mm). The final particle size is determined by downstream processing requirements. Grinding is carried out as a wet process with water content between 50 – 70% by weight.

Model of galvanic interaction occurring between a single sulphide mineral (pyrite or chalcopyrite) and grinding media is illustrated in Figure 4(a) based on mixed potential model . Pozzo et al. (1990) described an electrochemical model for a two-sulphide mineral/grinding medium system as shown in Figure 4(b).
