Phase 1A, Standard Lithium's first commercial lithium extraction plant, is proposed to be located at the South Plant, approximately 13 kilometers (8 miles) southwest of the City of El Dorado in Union County, Arkansas. ... nor the construction of additional brine supply and disposal wells which could result in increased lithium carbonate ...
The results show that a better leaching effect of Li can be achieved at a lower pulp density because of the larger contact area between the solids and the liquid, but the difference in leaching efficiency of Li is not significant for pulp densities in the range of 100–350 g/L. ... Selective lithium extraction and regeneration of LiCoO2 ...
