RE:RE: Thinking long for a payoffnopoo gotta thank you for all the work you have done on cyp. Wonder if we can do better than this nevada clay project......It was found that this process was effective in extracting lithium from the clay fines, but an acid dose of near 1150 lb acid per ton of mineralized material was required for 95% extraction. It was also revealed that extraction of lithium was nearly proportional to the acid dose. Overall results obtained by Hazen were consistent with those found by Chevron Research Company
