2. Our Proposed Initial Concept Ideas
Pre-Separation of Automotive Parts at Scrapyard
Pig Iron and Slag Recycling Method
Using the Mass Spectrometry Technique
Using Melting Points to Separate Alloy Metals

3. 1.) Pre-Separate Automotive Parts
Pre-separate the materials at scrapyard
Eliminates amount of unneeded scrap
Makes for a faster high alloy steel separation process
Saves time and money by not using advanced techniques
Manual labor would be used to separate car parts
Less harm would be caused to steel quality

4. 2.) Pig Iron/Steel Recycling
Pig iron would be worked into steel.
Pig iron is melted and a strong current of air is directed over it while it is being stirred or agitated
Causes the dissolved impurities (such as silicon) to be thoroughly oxidized.
More slag formers are introduced and more oxygen is blown into the bath
This burns out impurities such as silicon, sulfur, phosphorus,aluminium, manganese, and calcium, and removing their oxides to the slag.
Using an Electric Arc furnace, Pig Iron is blasted with slag in order to create a higher quality steel.

5. 3.) Mass Spectrometry Technique
Follows basic principles of electromagnetism
The magnetic field curves the ions based upon their unique charge to mass ratio
Different elements/ compounds will end up at different locations

6. 4.) Separation By Melting Points
Alloys put together in air-tight mixer
Mixer heats to different temperatures based on melting points
Melted metals separate from alloy and are transported using gravity
