Life+Cycle+Analysis

An explanation of the life cycle of the coin is given. This section is a list of steps describing the steps of mining/making of materials, production of coin, dissemination of coin, and the recycling/waste process; including an approximate timeline for each step in the cycle. This section is less detailed than the material source data and may include information from that section. An estimate of the overall life expectancy of the coin is based upon actual data from real world sources, which have been listed in the references. Provisions for reuse or recycling of the coin are built into the design and identified. (This section should be no less than 2 frames of the presentation). Images may be added to the description, if applicable, but should not be used as a substitute for the explanation or to increase the number of frames.

"Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites. Most iron is found in minerals formed by the combination of iron with other elements. Iron oxides are the most common. Those minerals near the surface of the earth that have the highest iron content are known as iron ores and are mined commercially. Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon content and adding other elements such as manganese and nickel to give the steel specific properties"

In its nearly pure state, copper is a reddish-orange metal known for its high thermal and electrical conductivity. It is commonly used to produce a wide variety of products, including electrical wire, cooking pots and pans, pipes and tubes, automobile radiators, and many others. Copper is also used as a pigment and preservative for paper, paint, textiles, and wood. It is combined with zinc to produce brass and with tin to produce bronze"

Copper mining usually takes place in very large, open pits. Although the figures vary from location to location, it can take over 3 tons of rock to yield 1 ton of copper. The process of mining requires the rock to be loosened by blasting with a combination of ammonium nitrate and fuel oil (called ANFO), so that the rock can be scooped up and examined. The process begins by drilling the rock to place the explosive. The blasted rock is then scooped up into large dump trucks that haul it to another location for crushing. Every mine has an area where waste rock, or overburden, is dumped. This is the rock that has to be removed before the ore is located. The ratio between ore and this stripped rock is referred to as the stripping ratio.
