Cobalt From Li-Ion Batteries - Part 3

We've almost given up on extracting lithium from our batteries now, so a cobalt extraction is plan B. Others have extracted cobalt from batteries before, but I haven't seen too many people effectively purify the product from nickel contamination (which is also in batteries, and extremely similar to cobalt from a chemical perspective). We'll be doing that in a future video, but for now we're extracting the transition metals from the precipitate we made in the last instalment.
