ore using many different methods depending on the ore itself. The process includes heating it up with silicon dioxide or and oxygen in a furnaces and then the parts of copper in the chalcopyrite are made into copper sulphide which then is made into metal copper then the sulphur in the chalcopyrite is created into sulphur dioxide which is used to make sulphuric acid and the equation for all this is known as 2CuFeS2 + 2SiO2 + 4O2 ------> Cu2S + 2FeSiO3 + 3SO2. After all those steps the copper sulphide

origin of the galaxy seems a mystery. But over time, the pieces of the puzzle are coming together. Scientists believe a supernova or star may have formed the universe. When the Earth first formed, it contained gasses which dissolved into the Earth’s molten planet. When this formation happened from the smaller bodies, these were called planetesimals. But not all planets are the same. The Jovian planets are shrouded by thick atmospheres that are rich in hydrogen and helium. These planets were formed

The Art of Welding Welding is defined as the process of joining together metal pieces or parts by heating the surfaces to the point of melting using a blowtorch, electric arc, or other means, and putting them together by pressing or hammering. Welding is more of an art rather than a skill. It takes a special person to be able to completely master the art. Skills that a welder would need to have would be a very detail-orientated mind set. (Welding Basics) anyone can weld, but nobody is going to

Chris Healy 12/08/2014 Nav. 350 Final Exam Question 1: The pattern of west to east is the result of "prevailing winds.” Is the pattern the same in the Southern Hemisphere? It’s commonly known that the winds rotate as the earth rotates, meaning prevailing winds are present in both the northern and southern hemisphere. In terms of the southern hemisphere, the belts are reversed. The southeast trade winds blow from the southeast toward the equator, rather than away from the equator which the northern

Bal Aluminum 2618 is melted in a graphite crucible and a stirrer is used to stir the melt. When the temperature of the melt reaches 510°C, the dried K2ZrF6 and KBF4, Si3N4 and AlN salt powders with weight ratio x wt%(x=2,4,6,8) were added to the molten aluminum. The stirrer assembly consisted of a graphite turbine stirrer fixed to a steel rod. Approximately 1Kg of alloy was then melted at 820°C in the resistance furnace of stir casting setup. Preheating

Andrew Carnegie was one of the most successful businessmen and most recognized philanthropists in history. He led the enormous expansion of the American steel industry in the late 19th century and became one of the richest men in the world. He used his innovative ideas and his determination to succeed to build one of the greatest family fortunes in the history of America. Not similar to others, Carnegie’s idea of being rich meant having the ability to help others; he contributed to the construction

as well as how the B4C technology compares to other surface treatment processes within the metal finishing industry in general. At present, over ninety-five percent (95%) of all functional surface treatments are surface coatings such as hard chrome, HVOF, PVD, and CVD / nitride; all of which extract an element from a secondary source then apply it to the work piece. Overall, the greatest challenge in metal finishing production is in achieving the required balance between the desired surface properties
