Smelting

Sub-Saharan trade route was the basis of the economy and politics in southern Africa. There was great lack of outside exposure so the entire political system was based on what people had to trade and how advanced in skills and practices they were. Iron smelting and trading was one thing that majorly influenced the…

to tell Fugui that all students must go smelt steel at school. Despite Jiazhen telling Fugui that his son needs more sleep, he refuses and ignores her and sends Youqing to school in his drowsy state. Fugui’s response to Jiazhen’s reasoning was: “Smelting steel is a duty. We can’t be politically backward. Mr. Niu praised us in front of everyone! Youqing has to go (to school).” As a result of his exhaustion, he falls asleep where he shouldn’t have and is crushed under a knocked-over wall. Fugui’s…

British dominance over China after Britain defeated China in the Opium War of 1839-1842. Some of the inventions that the Chinese made that we use today in the American society are: alcohol, the mechanical clock, tea production, silk, iron and steel smelting, porcelain, compass, gunpowder, movable-type printing, papermaking, etc. There was a law against the Chinese immigrating which proves that the Chinese were more hated than the Irish and the…

Due to today’s media which has sensationalized and embellished the more magical aspects of alchemy, the layman may imagine dark spirits and flasks overflowing with noxious chemicals. The layman may also think of alchemy as a trial and error process, in which the aspiring alchemist fumbles blindly towards his next success or failure. This is far from the truth. The infancy of alchemy is located in a Greece influenced Egypt ("Alchemists, Ancient and Modern."). Ancient Egypt, Alexandria, had…

1.0) The Ellingham Diagram 1.1) Introduction The Gibbs free energy (∆G) of a reaction is defined as the measure of the thermodynamic force that drives a reaction to occur. When ∆G is positive, it indicates that a reaction will not occur spontaneously while when ∆G is negative, the reaction is spontaneous. The Gibbs free energy equation is given by : ∆G = ∆H –T∆S ∆H refers to the enthalpy and is a measure of the actual energy that is released when the reaction occurs. A negative…

England is suffering, but the people are not fully aware of its impacts. They don’t know how industrialization can affect the future of our children and our grandchildren. While industrialization has made the lives of people better, the negative impacts vastly outweigh the positive. Before discussing the negative impacts of industrial revolution in this article, the positive effects should first be brought to light. For example, the Industrial Revolution is changing the role of women in…

purest value. It comes from ores, which are mined rocks rich in metals such as copper, gold, iron, and also lead. These rocks can go through various extraction methods and processes to separate the waste rock from the useful metals; methods such as smelting, milling, leaching, and electrolytic refining. Two of the strongest methods of refinement is electrolytic refining and leaching where copper is refined to 99.9% of its pure substance. This pure element has a reddish tone, doesn’t rust like…

Industrial robotics are quasi-intelligent machines that increase production rates, efficiency, quality, and safety in all aspects of manufacturing and assembly. They have the ability to pick up single or multiple objects and place them anywhere within their reach, weld simple and complex parts together, and use sensors to inspect material or parts at any point in the manufacturing process. Although robotic arms and automation are a newer technology, both are taking the manufacturing industry by…

Aluminum extraction consumes 49x106 Joules per kilograms of Aluminum recovered and Copper recovery by the smelting operation consumes 50x106 Joules per kilogram of Copper recovered (Woollacott and Eric, 1994) [2]. Hand picking or manual sorting can be utilized to sort Zorba, but it’s a highly labor intensive slow process and it is inefficient to separate optically…

Canada at the end of the second World War had started to make a name for itself. Canada was no longer seen as a country not strong to defend itself, but a country filled with brave men and women. As time went on and the war was being pushed back into the background Canada started to develop a close relationship with a very powerful country. Canada and America’s relation had started to take off and in every aspect made Canada stronger and more dangerous every single day. Canada and America’s…
