Jigs may handle from 7 to 25 tons per hour, and can handle particles ranging from 75 mm to 25 mm. At some operations, jigs are also employed in the cleaning stage. (Macdonald, 1983; Silva, 1986). Shaking tables consist of small riffles over which a slurry containing fme ore is passed. The gold settles into the riffles and, through a vibrating ...

Germanium is mainly a byproduct of zinc ore processing. It is a hard, grayish-white element; it has a metallic luster and the same crystal structure as diamond; and it is brittle, like glass. In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator. The development of the germanium

The jigs are placed in a conveyer furnace where the emitter and collector dots alloy with the germanium dice, which at the same time is fused to the base tab. Footnote: Other sources (Watt History) contradict this, stating that the collector dot was alloyed in a first pass through the alloy furnace and the emitter dot alloyed in a second firing.
germanium devices look leaky compared to silicon), some earlier transistors, especially metal can devices, have a problem very similar to paper caps with. "leakage" of moisture past the lead seals. Motorola had a very expensive job in. the 80's of digging up replacement germanium transistors to go into early. 1960's solid state receiver strips ...

Germanium detectors are semiconductor diodes having a p-i-n structure in which the intrinsic (i) region is sensitive to ionizing radiation, particularly x rays and gamma rays. Under reverse bias, an electric field extends across the intrinsic or depleted region. When photons interact with the material within the depleted volume of a detector ...
The Analytical Shift Toward ICP-MS. Although ICP-MS was first developed over 30 years ago, a number of older techniques are still in use by some laboratories. 3 Table 2 lists advantages and disadvantages of ICP-MS compared to other techniques such as inductively coupled plasma atomic emission spectroscopy (ICP-AES), flame atomic emission (flame photometry), flame atomic absorption, graphite ...
Germanium is closely associated with and is an analogue of silicon. VINOGRADOV [15] states: "Thousands of tons of germanium are added to the atmos- phere daily with the smoke of burning coal and oil." If so, it should be present in polluted air. Germanium is a strongly siderophilic element, concentrated in meteoric iron (and in some terrestial ...

About product and suppliers: diaphragm jig are artificial fishing baits to allure fishes during fishing and work splendidly. Many diaphragm jig make use of either color or vibration to create a curiosity in the fishes and make them move towards the bait. The hooks attached to the diaphragm jig are then used to catch the fishes when they strike it. These lures come of various types that either ...
For a germanium diode, Vpn is approximately 0.3 V, while for a silicon diode it is close to 0.6 V. 3.3.2 The p–n diode as a circuit element Diodes are referred to as non-linear circuit elements because of the characteristic curve shown in Figure 3.8. For most applications the non-linear region can be avoided and the device can be modeled as ...
