With acid leaching using 10-20% solids, 98-100% Li, Fe and P could be extracted. The leach liquor was subjected to a selective sequential precipitation route to extract 90-95% pure lithium as lithium carbonate/lithium hydroxide and 98% pure iron phosphate. Purified graphite was a derivative in the process. Low-cost acid leaching and low-temperature process . High pure (>90-95%) lithium product(s) . High pure 98% iron phosphate . 85% pure graphite is a by-product . Easily replicable on a large scale . Closed-loop recycling of reagents . Low Incubation time and high returns
