Chromium is an element that is found abundantly in ocean waters and the earth’s crust.1 It exists in nature in many forms including a metallic and trivalent state. It also exists in a hexavalent state, not normally found in nature, that is highly toxic.1,2 The food and supplement sources are trivalent chromium, which has a low toxicity level.1 Interest in chromium’s role in human nutrition dates to the 1950’s where it was first identified as having a role in glucose metabolism.1 Today, it is considered

Is Slope Determination a valid method to calculate the density of a metal? Slope determination is a valid way to calculate density because the slope of the data and the actual slope were close in value. When looking at the slope of the graph with the points, they were all relatively close. Three of the five point were even on the slope line. The formula of (y2-y1/x2-x1) allowed the finding of the slope of the line graphed and it also allowed the comparison to the actual slope of silver. This allowed

Captain Carbon explains the Creation of the Legion of Steel To understand the Legion of Steel, you must go back to its roots and learn why the Legion of Steel has been called upon to take on the steel wire forming and fastener manufacturing industries most challenging demands. It all takes place many years ago, during the dark days of poor and inconsistent steel wire supply. The long work day was coming to a close at Beta Steel with paperwork churning, manifests being completed and orders being

All metal assembling incorporates a cementing procedure. The metal is either atomised to a powder, or it is thrown. There is a few throwing strategies utilized today. A considerable lot of the techniques utilize the shape once, for instance sand form throwing, the lost-wax strategy and accuracy throwing. For bigger amounts of fluid metal, there are essentially two techniques: ingot throwing and persistent throwing. Ingot throwing typically utilizes a perpetual form made by cast press secluded by

What would we do without Iron? Iron is seen on the periodic table as the symbol Fe, how do you get Fe from the word iron? Well like most words we use, it came from the Latin word”Ferrum”. It was considered an important metal back in the ancient days because it was used from many purposes, such as what swords were made of to fight battles or to make hinges on castle doors (Forbes , 1965 , p 247). It has an atomic mass of 55.847 and its atomic number is 26 (Haynes, 2015). Iron is used all around us

Tungsten is a chemical element with atomic number 74 and symbol of W. The word tungsten comes from the language Swedish which means heavy stone. This is a rare, hard metal under normal conditions when it’s uncombined. Tungsten is found naturally on Earth only in chemical compounds. It was identified as a new element in 1781. Its ores contain wolframite and scheelite. The element is remarkable for its robustness. It has the highest melting point of all the elements. Also its high density of 19.3

We, the state of Minnesota, have a big decision coming up when it comes to mining the copper and nickel in the boundary waters. Sulfide mining has been stereotyped as a major pollutant to nearby waterways. As this may have been proven true with other mining corporations, PolyMet Mining has found a new way of reusing the sulfide as renewable energy instead of flushing it back into the waterways. Minnesota is home to one of the largest deposits of copper, nickel, and other precious metals. Currently

This is then placed in a furnace that is heated to temperatures up to 1000°C. Combustion of the coal releases heat, the sand and lime act as a fluxing agent, which removes the impurities of the iron, for example Iron (II) silicate. These impurities then float to the top where they are removed and discarded. Copper matte is then formed, a mixture of Copper (I) oxide and copper (I) sulphide which contains about 50-70% copper. The copper matte is then mixed

New studies have revealed that lead production varied in ancient Europe with production mirroring the rise and fall of the Roman empire in Western Europe but remaining strong throughout the rise and fall of the Roman empire in Eastern Europe. Lead production and toxicity persists to this day. Historical lead production Lead has fallen out of favor due to its toxicity however it was commonly used in ancient times. Some of the first evidence of lead is found in the form of metallic lead beads

EXPERIMENT : Iron in Breakfast Cereal by Atomic Absorption Spectroscopy OBJECTIVES : 1) To determine the actual iron content of different brands of cereals 2) To compare the experimental results with the values listed on the manufacturer’s labels. INTRODUCTION : Iron is one of the important minerals that is required for our bodies to function properly. Most of the iron in our body is found in the blood such as haemoglobin, approximately 60 -70% of the human body’s iron is found in
