Metallurgy

 What is Metallurgy? Metallurgy is the science and study of the interactions of metals and their properties. Also used for the extraction of raw ores. It is also the art of working metals, used for the process of seperating the materials in the ore by smelting, parting, or refining them. Nearly everything in our modern society is made up because of metals. Steel, Aluminium, Titanium, and Copper are used for bridges, boats, automobiles, and as well as the machinery that was required to produce them.

 Environmental Issues  For metals and raw ores to be extracted, they will need a great amount of energy for it to be extracted and processed properly. Therefore the use of fossil fuels come into for most countries. Ultimately polluting the air and atmospher e with greenhouse gases. But Industries such as "Air Liquide" are trying to strengthen environmental friendliness of metallurgy. The world is now heading towards a more "green" outlook of things such as expanding the use of clean technology and minimizing pollutant emissions, reduction of up to 90% of Nitrogen Oxide, and developing a new oxy-combustion solutions to drastically reduce CO2 and pollutant emissions.

 What we can do? Each dirty fuel relies on our money to support to turn a profit. The government refines liquid coal, authorizes new pipelines and refineries for tar sands, opens pristine, public lands to oil shale strip mining, and requires oil companies to use dirty biofuels, in addition to other government support for these fuels.
