History
Earlier in history, from about the time zinc was discovered, or, from the 12th century, zinc was used in many ways. Starting in that same time period, zinc was brought into the industry and was used to improve peoples lives. In 1374 in India, when it was officially recognized as the eighth metal known to man, it was being used for medicinal purposes, such as a cure for sore eyes and healing wounds on the body.
As the timeline goes, zinc become a highly used element in the indian population. Then, in the early 17th century, zinc spread to to China, where it was mainly used in the brass industry as a way to make brass rust less. Finally, after more than 150 years, spreading around the world, the United States learns of it’s uses and begins its own industrial path with zinc.
Around the 1850’s to the 1900’s, zinc was only able to be obtained by being produced from oxide ores. Later, more abundant sulfides became easier to obtain and remove zinc from it, therefore becoming the major source of supply from then on.
After many hundred years after zinc was used, it finally became reported by Moras de Respour, that zinc had been sucessfully extracted from an ore. Though, most of Europe was still unaware of zinc at the time until, Germany’s Margraf, Paracelsus

It is usually used as a coating on different elements or objects. Zinc is used to coat iron things like shovels, hammers, and nails. This process is called galvanizing. The first step of the galvanizing process is heating zinc to its melting point, so it may take the shape of the object that is planned on being galvanized. On a platform of some sort, should rest the object. Once the melted zinc is in a liquid state of matter, the zinc should be poured evenly on the object, as not to leave any bumps or unevenness on the object. The same will be done after the zinc has cooled on the side, and then flipped over to repeat the the same step on that
One of the first attempts to locate and mine this copper was back in 1771 when the first mining expedition was organized. English miners were sent to the New World to locate and mine the copper heard of in Indian tales that had been passed along by the French. These miners had begun their excavation in a clay bank where they had previously seen trickling green copper-containing water with pieces floating in the water nearby. Unfortunately, the frozen roof of the tunnel had thawed and lead to a cave in resulting in the first failed attempt at mining copper in Michigan.
Silver has always been around but it wasn't until the 1500's to the mid 1700's that the
The creation of societies in the West resulted in the blossoming of three new industries: mining, ranching, and farming. Mining began at large with the discovery of gold in California in 1849 and continued with other discoveries and “rushes” later on; these rus...
Gold has been valued in our cultural history for as long as societies have been able to adopt this valuable metal’s unique properties. Gold is unique in its inherent marvellous glossy shine. Gold is particularly malleable, conducts electricity, doesn’t blemish and blends well with other metals. Because of these exclusive properties, gold creates its ways in our everyday life in many ways or form. Gold has always had remarkable significance, shown by most civilizations as a symbol of wealth and power. Gold has captivated most of cultures around the world and the passion for it brings to the extermination of some cultures and the growth in condition of others. This essay explores the use of gold over time and perception of the cultures that surround by gold.
The original penny, first produced in 1787 by a private mint, was made of 100% copper. This composition would continue into the 1800's. Tin and zinc were added to make the penny bronze, and eventually the tin was removed. A copper/zinc ratio of 95/5% was used until 198...
People discovered salt around 900 B.C. They would dig up salt near the Dead Sea and in South America. Salt has been important in the world’s culture for thousands of years. People used to use it to preserve meat or fish. Salt was so valuable that in several places, some would use it as money and others would trade it off for something else. (Aasen, et Al 1999).
Mr. Cronstedt discovered nickel in a mineral called niccolite. He originally planned to extract copper from this new mineral but got none at all. This is why nickel, at first, was called "false copper". Instead, Cronstedt got a silvery-white metal, which was eventually used for other things.
It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It is obtained by electrolysis of chloride or hydroxide.
Uranium, a radioactive element, was first mined in the western United States in 1871 by Dr. Richard Pierce, who shipped 200 pounds of pitchblende to London from the Central City Mining District. This element is sorta boring but I found something interesting, they used it to make an an atomic bomb in the Cold War. In 1898 Pierre and Marie Curie and G. Bemont isolated the "miracle element" radium from pitchblende. That same year, uranium, vanadium and radium were found to exist in carnotite, a mineral containing colorful red and yellow ores that had been used as body paint by early Navajo and Ute Indians on the Colorado Plateau. The discovery triggered a small prospecting boom in southeastern Utah, and radium mines in Grand and San Juan counties became a major source of ore for the Curies. It was not the Curies but a British team working in Canada which was the first to understand that the presence of polonium and radium in pitchblende was not due to simple geological and mineral reasons, but that these elements were directly linked to uranium by a process of natural radioactive transmutation. The theory of radioactive transformation of elements was brilliantly enlarge in1901 by the New Zealand physicist Ernest Rutherford and the English chemist Frederick Soddy at McGill University in Montreal. At dusk on the evening of November 8, 1895, Wilhelm Rontgen, professor of physics at the University of Wurzburg in Germany, noticed a cathode tube that a sheet of paper come distance away. He put his hand between the tube and the paper, he saw the image of the bones in his hand on the paper.
A wide variety of coating alloys and wrought alloys can be prepared that give the metal greater strength, castability, or resistance to corrosion or high temperatures. Some new alloys can be used as armor plate for tanks, personnel carriers, and other military vehicles.
Z Energy is New Zealand based company supplying fuel. Years ago, New Zealand company Infratil Limited and the Guardians of New Zealand Superannuation got together and bought Shell 's New Zealand downstream business. They were as Greenstone Energy in whole New Zealand. They get their business idea from whole kiwi peoples through their suggestion box and service stations, that what they want from Shell. They came up with the new idea and new name Z Energy.
...rms a thin, strong, water-resistant, layer of zinc carbonate, which protects the metal from further corrosion. (Galvanization 2014)
The history of gold is that experts of fossil study believe that bits of natural gold were discovered in Spanish caves back in 40,000 B.C, used
Zinc is an essential trace element for many living organisms. While this can be said about other essential metals, zinc is unique in its physiochemical properties that give it the ability to interact with donor groups of different ligands, resulting in a broad range of stability constants and diversity of the biological functions and processes that zinc is involved in. It was discovered and recognized as a new metal in the eightieth century, While its biological essentiality was found by Raulin for the growth of Aspergillus niger In 1869 [1]. In 1933 Zinc was found essential for the growth of animals while studying its effect on rats. [2]
