Seeing the pictures, seems a very good equipment.
The advantage of using a mill and shaker table with a magnetic separator lets you work as clean as you can, generates low toxic waste and create a lots of base materials for other products.
I use the fiberglass to mix it with concrete and make decorative pavement bricks, the plastics(granules) can be used to make road covers(asfalt, mixed with the ash and bitumen and other components) the magnetic material can be processed(if) containin any gold, in a sulfuric cell then recycled as metal at any junkyard.
You can make more money then jus burning everything and creating waste and poisoning your neighbourhood.
If labor is cheap, recovering and sorting would be an economic and feasable way to separate everything before proceeding to other processes, and there is more money to make from copper and silver, gold would be the clean profit this way.
There are several solutions for processing the material your friend has, some of them already presented by the members of this forum...but planning everything in advance could help very much.
Be safe,
Pete.
