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

Technology can recover lithium in the most desired marketable form, apart from iron phosphate. The derived values can be used for multiple applications apart from new battery manufacturing.
