Hydraulic Classification. A number of tests were made with quartz paired with galena, antimony, arsenopyrite, magnetite, sphalerite, etc., in different proportions, and with a velocity varied between wide limits, in order to determine whether a fixed ratio existed as to the diameters of the grains of the two minerals.

Figure 3.5.5 3.5. 5: Limonite, hydrated oxide of iron. After carbonates, the next most common non-silicate minerals are the oxides, halides, and sulfides. Oxides consist of metal ions covalently bonded with oxygen. The most familiar oxide is rust, which is a combination of iron oxides (Fe 2 O 3) and hydrated oxides.

The angles tested were 0°, 5°, 8°, 10°, 15°, 20°, 25°, 28° 30′ and 30°. Of these, 5° to 10° gave the narrowest angle of wedge with all the different water-quantities. This conforms with Rittinger's and Linkenbach's requirement, namely, that fine slimes must be prevented from settling on the feed-sole.

Galena is by far the greatest ore of lead. Galena is the most common mineral containing lead, and contains mostly lead. Since the extraction process is so simple, lead has been extracted from Galena since the earliest times. To quote Allen N Wollscheidt, "Galena, back 75 years ago, was the stuff -- the crystal -- of crystal radio sets.

3. LUSTER (specimens 12 -19) (Pellant, p. 27) Luster is a qualitative judgement about the way in which the mineral reflects light. We are really concered with one thing: does the mineral appear metallic (it looks like a piece of metal), or is it non- metallic (it looks glassy, or like pitch, or clay, or pearly, etc. It just doesn't look like metal.) ...
Galena, Cubic, Approximately 2.5″-3″ Length, 1 1/4lbs., Single Piece. Galena is a mineral composed primarily of lead (II) sulfide (PbS).
