The QX3 Computer Microscope
Introduction. Any microscope that uses visible light to illuminate the object is restricted to magnification of about 200 times. In order to see a feature of the object, the feature must scatter the visible light. In order to scatter visible light, the feature must be at least as wide as the wavelength of the light.

Porphyry Copper Gold Ore Under the Microscope
Jan 13, 2016· This could be possible but it is very hard to tell even under 175X magnification. One of the things that interferes with the identification is actually the light on the microscope. Minerals are better identified under natural light or ambient light, where they don't gain any color from reflections.

If an ore reacts positively to shear stress, a combination of compressive and shear is used. The Loesche patented shearfree grinding is used where pure compressive comminution is desired. Through the use of shearfree grinding the percenage of finest grain can be additionally t reduced with regard to the already steep product particle size curve.
Sharpening Plane Irons Chisels
Put the tool in your honing guide and set it so the cutting bevel is dead fl at against the stone. Most tools come ground at a 25° bevel, which is good for most tasks. Mortising chisels should be ground at 30°; tools for light par ing only can be set for 20°.
Influence of raw material particle size on quality of pellets
Ore is dried before grinding. At present iron ore Þnes and limestone Þnes of 10 mm size are ground together in a ball mill to get proper size with a thoroughly mixed product. The schematic diagram of pellet plant grinding circuit is shown in Fig. 1. The required ball mill product size for pelletisation process is shown in Table 1. Pellet plant receives 60 to 80% NMDC rake iron ore
