Kinetic study on carbonation of crude Li2CO3 with CO2
... The recovery of CO2 and production of pure Li2CO3 precipitate can be accomplished by heating the purified lithium bicarbonate solution under vacuum conditions. The precipitation process (see Eq. (6)) is conducted at 353 K and 0.035 MPa, which will not be further covered in this paper. 2LiHCO3(aq) Li ...
