Largest Gold Nuggets Discovered: Welcome Stranger And Hand Of Faith...

Gold nuggets are naturally occurring large masses of native gold found in alluvial deposits. Often they are concentrated by watercourses and recovered by placer mining. In other instances, gold nuggets are found in piles of residue in sites where mining operations once took place. Two gold nuggets are noted for being the largest masses of gold ever discovered. These are the “Welcome Stranger” and the “Hand of Faith”. Their respective “largest” titles, however, carry further qualifications. The Welcome Stranger Gold Nugget: The exact distinction given of this gold nugget is: “the largest alluvial gold nugget ever found”. It was discovered on February 5, 1869 at Moliagul, a small township...

Ruthenium: Most Versatile Of The Platinum Group Metals...

Arranged by name alphabetically, ruthenium is the last of six metallic elements in the platinum group. This precious metal is characterized as being both polyvalent and versatile. In fact, it is known to be more versatile than any of the other five precious metals in the platinum group. A hard, white metal, ruthenium is known to have four crystal modifications. While it does not tarnish under normal temperature, it does oxidize readily when exposed to air. It can be plated by means of two methods: thermal decomposition and electrodeposition. Following is a list of some of the properties of ruthenium: General: • Chemical Symbol: Ru • Atomic Number: 44...

Silver: Precious Metal With The Highest Thermal And Electrical Conductivity...

Silver is generally described as a soft, white, lustrous metallic chemical element. It occurs naturally in its pure form, as an alloy with other metallic elements (especially gold), and in chlorargyrite and other minerals. As one of three coinage metals (the other two being copper and gold), silver is very malleable and ductile. Of the different metals, silver is known to have the highest thermal conductivity. Similarly of the different known elements, silver has the highest electrical conductivity. Provided below are some of the properties of this precious metal. General: • Chemical Symbol: Ag • Atomic Number: 47 • Category (as an element): Transition Metal • Group/ Period/ Block...

Krugerrand: Most Well-Known Precious Metal Coin...

There are thirty-three known bullion coins in the world. Of these, 5 are made of platinum, 1 of palladium, 9 of silver, and 18 of gold. And of all these precious metal coins, the South African gold bullion coin Krugerrand is perhaps the most popular. In 1967, the South African Mint Company introduced the Krugerrand, with the intention of circulating it as currency. Its status as a legal tender was seen as the best way for marketing South African gold around the world. In fact, thirteen years after its introduction, this precious metal coin accounted for about ninety percent of the gold coin market. The Krugerrand comes in four varieties: 1. One-tenth ounce coin (0.11 troy ounce in...

Iridium: Most Corrosive Resistant Precious Metal...

Iridium is a transition metal belonging to the platinum group. Its main characteristics are that of being hard and brittle and of being silvery-white in appearance. It ranks next to osmium in being the densest element. As to its main property, this is best expressed in its being considered the most corrosive resistant of all the precious metals. In fact, this is shown even in temperatures of as high as 2000°C (3632°F or 2273.15°K). Iridium was discovered in 1803 by the English chemist Smithson Tennant. It was identified from the residue of platinum ore which was dissolved in nitro-hydrochloric acid (also known as aqua regia). Platinum ores are still the main sources today of iridium. The precious metal...

Gold Standard: Definition And The Three Distinct Kinds...

The gold standard is defined in many different reference materials as a monetary system in which the unit of currency used is a fixed quantity or weight of gold. Under this system, all forms of money, including notes and bank deposits, were freely converted into gold at the fixed price. There are three known kinds of gold standard that have been adopted since the early 1700s – the gold specie, gold exchange, and gold bullion standards. Following is the definition and a brief historical account of each. Gold Specie Standard: In this gold standard, the unit of currency is linked to the gold coins that are in circulation. More specifically, the monetary unit is associated with the unit...

Gold As An Investment: Ways Of Investing In Gold...

posted on: Aug 3, 2014 | author: admin

Four of the nine known precious metals are regarded as investment commodities. Of these four, gold is the most popular. Investing in gold is a way of protecting against crises that may be brought about by economic or political instability or by social unrest. There are at least six ways of investing in gold: Buying gold coins: This is the most popular way of investing in gold. Gold bullion coins are typically priced based on their weight; a premium is added to the gold spot price. Gold coins may be bought or sold over the counter in most Swiss banks. Buying gold bars: This is the most traditional way of investing in gold. As in gold bullion coins, bullion gold bars can be bought or sold over the counter in most Swiss banks, as well as in major banks in Liechtenstein and Austria. There also are bullion dealers that...

Gold And Silver: The Two Precious Traditional Coinage Metals...

posted on: Aug 3, 2014 | author: admin

Four transition metals make up group 11 of the periodic table of elements. All, except one, are considered traditional coinage metals. Qualifying this further, only two of these three traditional coinage metals are considered precious metals. These are gold and silver. Gold and silver are rare and have high economic values. These things can’t be said of copper, the other traditional coinage metal. Occurring in nature in metallic form, these two precious metals can be produced sans the use of extraction metallurgy. These other characteristics of gold and silver make them both well suited for coinage: • They are not radioactive. • They are more ductile or softer than most other elements. • They are less reactive compared with other elements. • They have excellent luster. • They have higher melting points compared with other metals. The high-ductility property of gold and silver means they can be easily damaged...

Bullion: Mass Of Precious Metals

posted on: Aug 3, 2014 | author: admin

Bullion is a mass of any one of the known precious metals. By strict definition, precious metals are those metallic elements that are rare. Bullion is commonly made of either gold or silver. Its value is determined by the worth of the metal rather than by its face value as money. To put it another way, bullion is valued based on the mass and purity of the metal used, instead of its artificial currency value. New sources of ore have been discovered and there also have been improvements in the mining and refining processes. These two factors may cause the values of gold, silver, and the other precious metals to diminish. Also, the “precious” qualification of a metal is determined by the market value or high demand. Bullion is traded on commodity markets in two forms: bulk ingots or coins, the latter minted by the government of a country....
