Generally when we speak of precious metals we think of Platinum, Gold, and Silver.
In a broader sense, however, the "precious metals" currently traded on the Precious Metals Exchanges includes not only those 3 metals but also palladium, iridium, rhodium, osmium, and ruthenium.
Historically Aluminum was once considered a precious metal because of the difficulty of refining it to its pure form. Modern refining methods have caused a precipitous drop in its price since the 1800s to where it is now one of the cheapest metals.

What does 14ktg mean?
"14ktg" typically refers to 14-karat gold, which is an alloy containing 58.3% pure gold and 41.7% other metals, such as copper or silver, to enhance durability and alter color. The "g" may denote "gold" in some contexts. This standard is commonly used in jewelry to balance quality and affordability.
What are some things that are mined?
Some common materials that are mined include metals such as gold, silver, copper, and aluminum, as well as minerals like coal, limestone, and salt. Additionally, precious stones like diamonds and various industrial minerals such as gypsum and potash are also extracted through mining. Each of these resources plays a crucial role in various industries, from construction to technology.
what does a p mean on gold?
A "P" on gold typically indicates that the item is made of gold that has been alloyed with other metals, often referring to its purity. For example, "P" can denote that the gold is "plumb," meaning its actual gold content is as stated, without any hidden impurities. Additionally, in some contexts, it may represent a specific karat weight; however, it's essential to consider the accompanying markings for precise identification.
What is 10 percent gold?
If metal is 10 percent gold, it is an alloy in the proportion of 1/10 gold and 9/10 some other metal (usually silver).
What do the letters 14k f mean on gold band?
14k F means gold fill not gold plated gold fill is better than plated but not solid gold just a thin layer of gold applied to some other metal
What are some precious metals for jewelry other than gold?
There are multiple types of gold aside from the traditional yellow gold. White gold and rose gold are commonly used in jewelry making. Other precious metals commonly found in jewelry are silver and platinum. Silver is a soft metal and is typically mixed with other metals such as copper. Platinum is much more rare than gold or silver and tends to be far more expensive.
What are some example of the precious metals?
Gold and Silver are the best known precious metals. Others are ruthenium, rhodium, palladium, osmium, iridium, and platinum. A metal is considered precious if it is rare.
What is non precious metals?
Non-precious metals, such as copper, aluminum, iron, nickel, zinc, tin, lead, and titanium, are common industrial materials that lack the rarity and high value of precious metals like gold and silver.
What are some of the purposes for a metal detector other than looking for coins on the beach?
Advanced metal detectors can check for the difference between coins and gold nuggets. You can look for other precious metals or gold rings.
Why can Gold occur in a free state but sodium cannot?
Sodium is much more reactive than gold or other precious metals. Even metals will form oxides, chlorides, and other minerals. Sodium, however, reacts with air and especially with water, and with some hydrated minerals.
What precious metals are in a freon compressor?
Freon compressors typically contain small amounts of precious metals such as gold and silver, primarily in the electrical contacts and circuit boards. Additionally, some may have palladium in their catalytic converters. However, the overall quantity of these metals is minimal compared to other electronic devices, making them less significant in terms of precious metal recovery.
What is the difference between precious metals to metals?
Gold and Silver were some of the early "precious metals" to be isolated. They are relatively rare. Gold is relatively nonreactive and thus maintains a wonderful luster. It also has tremendous workability. Silver is somewhat similar, not as rare as gold, but has a nice luster, and good workability.Other metals such as Platinum and Palladium also are relative rare and non reactive.This would compare to copper which was probably initially isolated in the form of bronze, but later purified. Somewhat more common than the precious metals, and corrodes quickly. Iron and other metals were refined later in our history. It has great strength, but oxidizes quickly.The "Ancients" discovered the beauty and workability of gold and silver, and started using them for currency and jewelery.In recent times, gold and silver have been used in electronics due to their high workability and low resistance, and resistance to corrosion. Yet much of the value still is attributed to the value given by the ancients as "precious".
What were crowns from medieval times or the middle ages made from?
The kings crown was made of gold and sported some of the largest diamonds and other precious stones ever found in the world, called the crown jewels.
What is L mean on gold?
The "L" in the context of gold typically refers to the purity of the gold, specifically indicating "carat" (often abbreviated as "K" for karat). For example, 24K gold is considered pure gold, while 18K gold contains 75% gold and 25% other metals. In some contexts, "L" may also refer to "London," as in the London Bullion Market, which is a major trading hub for gold and other precious metals.
What are the some example of metal?
Gold and Silver are the best known precious metals. Others are ruthenium, rhodium, palladium, osmium, iridium, and platinum. A metal is considered precious if it is rare.
Is copper weighed in troy ounces?
These units are used only in some countries; in the SI system gram, kilogram, ton are used.
Who created gold?
Gold is not a man made material it is a precious metal found in some metals and stones gold can only be purified by man. Gold purity level can only ever be up to 99%.
