This suggests that the lithium is not the residue of brines from a land-locked salt lake." "Nitric acid was tried for selective leaching with positive results. At low temperature and with no pressure, 100% of the lithium was put into solution while avoiding the leaching of metals and most of the other elements. Other leached materials were carbonates (1/2 of the present iron was found under carbonate form) and salts (Mg, Ca including sodium and lithium). With the expected mined volume of over 7 million tons annually for 20,000 tons of lithium hydroxide produced, this type of leaching strategy could help keep capital costs down by, amongst other things, allowing for the design of a low-cost leach tank." |
