A small sample from the gold is placed into a testing Resolution containing the right acid. If the gold does not react on the acid, which include changing color or dissolving, then It's a sign of high-quality, pure gold.

Well I just finished two unoffical tests on refining pentium pro cpu chips. I crushed two (2) pentium pro chips very wonderful and ran them through an Aqua Regia of Nitrate soda and hydrocloric. I then neutrilized the nitric acid to .60 PH and after that precipitated with Sodium Met. Permit a single batch of two sit for eight several hours and afterwards decanted off liquid and washed the mud with distilled water along with the aqua ammonia then rewashed once again for thrice with distilled water, dried mud on incredibly hot plate and then set it in my oven.

After the acid treatment, the ensuing solution is filtered to get rid of any solid residues. The remaining liquid contains a mixture of dissolved metals, such as gold, which really should be additional processed to separate the specified treasured metal.

The difference involving a porcupine as well as a CPU is that all those little “quills” are gold-plated and might be worth sending to a professional gold refinery for processing.

It truly is essential to warmth the gold concentrate evenly to stay away from any burning or scorching. As being the gold concentrate melts, you will discover that it takes on a shiny, metallic visual appeal, indicating that it's been successfully smelted.

Although the level of gold within a CPU is small, the collective amount from several CPUs can be significant. Recycling initiatives permit with the extraction and recovery of this useful metal, contributing to useful resource conservation and sustainable methods.

Although the gold in CPUs may not be suitable to be used in jewelry as a consequence of its industrial-grade purity, it might nonetheless be used in many industrial apps, such as electronics manufacturing and chip packaging.
