The lithium Ark process is able to produce lithium hydroxide directly from lithium chloride with significantly less energy than the lithium chloride electrolysis, a process that is already 40 years under investigation without achieving industrial application.

The process avoids the use of lime and soda ash.

 

The lithium chloride is produced from brines from

• salts flats (Salars) by solar evaporation or Direct Lithium Extraction (DLE) and

• geothermal and smackover brines by DLE.

​​

In the block diagrams below Lithium Ark process is compared with:

• conventional liming process that uses soda ash and lime

• lithium chloride electrolysis, a process patented 40 years ago, without any breakthrough due to chemistry limitations
