Detailed introduction
Elephants in the Nevada Desert: Carlin
Dec 12, 2019Carlin-type gold deposits account for 9% of the world's gold production. These deposits are typically low grade, high tonnage and they appear to be largely confined to Nevada, USA.While gold was first discovered in Nevada in the 1870's, it wasn't until 1961 when Newmont discovered and developed the first mine along a structurally faulted area now known as the Carlin Trend.

Airborne Geophysical Methods
Oct 17, 2019Specifically, this is used when exploring for magnetite-rich deposits during iron ore exploration. However, occasionally the variations can be caused by the iron sulphide mineral pyrrhotite, which may directly point to a sulphide-rich body containing valuable metals such as copper, lead, zinc, silver and even gold.

Ore sorting
Mar 04, 2019At Vista Gold's Mt Todd gold project in Australia the combination of XRT and laser-based ore sorting has shown a coarse fraction (+16 mm) high pressure grinding rolled product can efficiently be separated into waste and ore piles. The laser sensor, in this case, detects quartz in the ore after it has already gone through an XRT-based process. Get price

An interpretation of the infrared optical properties of gold smoke deposits is presented together with new experimental results. This interpretation is based on an application of classical electromagnetic theory. The gold smoke deposits are assumed to interact with infrared radiation as if they were sheets of an essentially uniform material which is characterized by an average electrical Get price
US7282727B2
A method and apparatus is disclosed for an electron beam directed energy device. The device consists of an electron gun with one or more electron beams. The device includes one or more accelerating plates with holes aligned for beam passage. The plates may be flat or preferably shaped to direct each electron beam to exit the electron gun at a predetermined orientation. Get price
Conceptual Design of a Nano
Typically, SPP waves propagate enclosed in the interface between a metal and a dielectric layer. Noble metals, such as gold or silver, do support the propagation of SPP waves, but at higher frequencies than graphene. Furthermore, SPP waves on graphene exhibit additional advantages including easy tunability and low ohmic losses [60,61,62]. Get price

The exact physical mechanism the archons use to influence humans may be by means of Electromagnetic fields. When your body hears a physical human voice, it is vibration which travels via electromagnetic frequency to your ear drum. Your ear converts this vibration to a signal that can be interpreted by your brain. Get price

Processing, smelting and refining gold
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. Get price
