What is inside a game console?

A game console is a compact computer: one large main board under a heat sink, a power supply, a cooling fan and, in some models, a disc drive or a hard drive. The main board is what makes it worth recovering, because that is where its precious metals are; the chassis and the heat sink add steel, aluminum and copper.1

Drawing of a representative living-room game console, not a specific product, standing on its stand with its near side panel removed and a controller beside it. Inside: the main board with the processor under a copper heat sink and heat pipes; a large blower fan with its hub cap cut away to show the ring magnet in its brushless motor; the optical disc drive, cover off, with the disc on a small spindle motor and the laser pickup with the two tiny magnets of its focus and tracking actuator; an M.2 SSD and the power supply. One controller grip is cut open to show its rumble motor, its two curved magnets and its off-center weight.

How a game console is recycled

A console stores accounts and saved games, so it is reset, or its drive is removed, before it is handed over.2 A recycler typically opens the case and lifts out the main board, which is graded with other boards and sent to a copper smelter; there the copper gathers the gold, silver and palladium, and refining separates them.3 The steel chassis and shields are pulled from the shredded remainder by magnets and the aluminum fins by eddy-current separators, and the copper of the heat sink and heat pipes goes on to be smelted and refined.45 Its magnets are small ones, in the fan, the disc drive and the rumble motors of the controllers. A console with a hard disk drive is the exception: that drive carries a pair of stronger magnets, commonly neodymium, and it can be taken out whole so that they are separated from the rest.67 The tantalum in its capacitors and the gallium in its laser diode are among the metals rarely recovered from old products.8
