 These molecules are going on a short journey here in the States. Gretz leads the tour. Then you get pumped down to that leaching tank there where you'll be dissolved in sulfuric acid. Some of the minerals, like nickel and cobalt, dissolve. The graphite in the mix doesn't. That helps sort them apart. Then you're going to go over to our impurity removal station. The exact combination of minerals gets fine-tuned, and finally it's dried back into a powder, currently sitting on a shelf in 25-pound bags.
