Implementation of an Integrated Technology for Processing Brines of the Calcium Chloride Type to Obtain a Bromineless Lithium Concentrate
The structural features of halide varieties in an analogous series of double compounds of aluminum and lithium are studied. The possibility of transition of a bromine-containing version of the double compound of aluminum and bromine into a lithium concentrate is shown. Methods are found for preparing a lithium concentrate without bromine admixture. After bromine is industrially removed, the resulting lithium concentrate is used to obtain the following lithium products: lithium carbonate and lithium hydroxide monohydrate. In an integrated scheme, magnesium hydroxide after separating bromine and lithium products is precipitated to produce a calcium chloride solution.
