This invention relates to a method for preparing a lithium activated alumina intercalate solid by contacting a three-dimensional activated alumina with a lithium salt under conditions sufficient to infuse lithium salts into activated alumina for the selective extraction and recovery of lithium from lithium containing solutions, including brines.

Porous activated alumina based sorbent for lithium extraction

A method for the selective precipitation and recovery of manganese from a manganese containing solution, such as a geothermal brine is provided, wherein the geothermal brine is contacted with ammonia, an ammine, or ammonium salt at a pH of greater than about 8.0 to selectively precipitate manganese having a purity of at least about 95%. Also provided are methods for the selective recovery of manganese and zinc from a brine solution.

Separation of manganese from brine

This invention relates to a method for the selective recovery of manganese and zinc from geothermal brines that includes the steps of removing silica and iron from the brine, oxidizing the manganese and zinc to form precipitates thereof, recovering the manganese and zinc precipitates, solubilizing the manganese and zinc precipitates, purifying the manganese and zinc, and forming a manganese precipitate, and recovering the zinc by electrochemical means.
