RE:Why no data for the purity?What are you talking about??? They said they recovered upwards of 90+ percent of the cathode metals from one pass in the stages 1and 2. Now they say they have subsequently generated high purity filter cake of metals that can go right back into a new battery with minimal downstream processing. But metals obtained from mining sources would require significantly more processing and cost to go into a new battery manufacturing. How much more purity do you want?????? Gezzzz, give Larry a break!!!
