Its rare . The ingots are then sliced into wafers about 1 millimeter thick. Then, the cylinder is sliced into thin wafers. These wafers are cleaned mirror-smooth before going through a sophisticated procedure to generate chips. Our best advice is to always check into the rarity and collect-ability of your computer chip before considering sending it to a precious metal recycler with the intent of scrap gold refining.It may be worth quite a bit more due to it's collectible value than in it's . When the World runs out of rare earth metals we wont be worried about computers we will have been extinct for years. It is capable of pressing samples in supporting steel rings as well as in the standard unsupported format. Also some other parts inside may be aluminum, like the heatsink that sits on top of the CPU chip. I doubt the US will run out of rare earths; its more a question of when the practical cost of extracting them becomes lower or higher than the cost of importing them that tips the equation. There will have to be an increase in its supply to meet the world's growing demand for electronics. Molycorp Minerals, the current owner, is now reopening it with the goal of producing 20,000 tons of rare earths in the near-term, and 40,000 tons by mid-decade. The majority of processing capacity for these metals is located in China, which supplied 80% of the United States' rare earth imports between 2014 and 2017.
