Precious Metals Research Paper

When mining gold there is about 1 ounce of gold per ton though when mining on the surface that statistic drops to about 0.5 ounce of gold per ton. Gold is highly valued at about $120,000 per truck this is because gold is malleable, and it never loses luster or rusts. Next, copper which is also a valued metal because of its specific properties, it conducts electricity and bacteria doesn’t like to come in contact with copper. Many people have found the value in copper and trade copper in the same way stocks and shares of companies are traded. And finally bronze which is made of 80% copper and 20% tin, bronze is used in the manufacturing of bells. Bronze is used in the making of bells because when copper, a pure substance, is hit it creates a ripple effect making the bell easy to dent, with tin the rows of copper atoms are more stabilized, but too much tin can result in a bell cracking as the Liberty bell did.

Is the recycling of electronics (e.g. mobile phones) a more economically viable method of sourcing rare earth metals than mining?

1. Suppose you find a yellow piece of metal in a stream. How could you tell if it is real gold?

For example, silver nitrate formed a white precipitate when it was tested with ammonium chloride. In contrast, unknown 3 did not formed any precipitate with ammonium chloride. Ammonium chloride change the color of unknown 3 to a light green while the solution of silver nitrate and ammonium chloride was cloudy white solution. Likewise, the metal in unknown 3 could have been Calcium neither. Data and observation shows that calcium nitrate whether formed a white precipitate or did not react at all while unknown 3 formed an orange precipitate. Therefore, silver and calcium are not the two metal present in unknown

Copper is formed by the melting and cooling of molten rock and found fairly close to the Earths’ surface, alongside with silver it has sulphite within the ores as they are created in brine which is a boiling salty water deep within the Earths’ crust and then pushed up through ocean vents and create a chimney like effect. Gold is formed through Hydrothermal-hot water-fluids of which are extremely rich in sulphur and found generally near or in

The unknown contained silver, as both the unknown and silver solutions turned red and formed red precipitates with the addition of potassium chromate.

In well 3A there was a chemical reaction between the sodium phosphate and copper sulfate. There was a light blue precipitate formation which proves there was a chemical reaction.

Government agencies are just protecting themselves and don’t care about the Native American communities or people! Gold King Mine was an abandon gold mine, which stored mine waste water for many years and neglect by Environmental Protection Agency (EPA) has led to (the Environmental disaster of 2015.) The waste water stored was of heavy metal rust, Lead, Arsenic, Cadmium and Copper. Which was breached during an excavation of the mine, “…excavating above the old adit, pressurized water began leaking above the mine tunnel, spilling about three million gallons of water stored behind the collapsed material into Cement Creek” (Environmental Protection Agency), on August 5, 2015, at Gold King Mine near Silverton,

The German alchemist, Albertus Magnus from the 13th century, is the man who is known for first identifying Arsenic. Being number 33 on the periodic table, arsenic falls inside the metalloid line because of its characteristics. According to the Green Facts website “Arsenic is a naturally occurring element that can be found in the Earth crust.” (Arsenic n.d.) It

Sterling silver is a combination of silver containing 92.5% by mass of silver and 7.5% by mass of different metals, like copper and other. The sterling silver standard has a base millesimal fineness of 925. When we talk about fine silver it is of 99.9% pure which is soft and shiny in quality. It is used for making various types of silver jewelry, coins and many other precious objects.Sterling silver is quite different form pure silver. It contains 92.5% silver and the rest are other metals used in it to make something. The silver is generally alloyed with copper to give it quality while protecting the pliability and appearance of the valuable metal. It is originated in Europe as early as the 12th century in the area that is now northern Germany.

Platinum was first discovered by a man named Julius Scaliger. Julius Scaliger first discovered Platinum in an Inca village in 1577. Julius wrote the first written account about platinum. In 1735, Antonio de Ulloa, a spanish explorer encountered platinum with the Incas. Antonio de Ulloa decided to start to study the new element. It was recognized as an element in 1735, not 1577. Scientists now know that Incas started using platinum in hieroglyphics hundreds of years before any european explorer “discovered” it. Platinum currently is almost as rare as gold, but less valuable. It is currently found in South Africa, Canada, United States, and Russia. Platinum is extremely rare to find by itself, but is found as a byproduct

Aluminum is made from extracting aluminum oxide from bauxite. Traces of aluminum have been found as far back as 5300 BC, in ancient Persia strongest clay cooking vessels. In the early 1800s Sir Humphrey Davy was the first to establish its existence, and name it. Around ten years later a French scientist found red clay that contained large amounts of aluminum, which was called Bauxite. Aluminum never occurs naturally in nature; even today no one has ever found pure aluminum. In 1825 a small

The way phosphorus was discovered I find to be interesting. Henning Brand a German in 1669 was conducting an experiment using urine to turn into philosopher's stone that can turn certain metal into gold ("The Element Phosphorus." It's Elemental -. Web. 23 Dec. 2015. ) He then isolated a white material that glowed and little did he know that it was white phosphorus. Phosphorus is represented by the letter P on the periodic table of elements. It in group 3 and its atomic mass is 15. It is part of the pnictogen family. It general classification is non-metal.
