Progress on lithium and magnesium separation and recovery from the salt lake brines

According to the test result, the corrosion characteristic of flake cast iron in salt lake bittern is analyzed in this article.

The steps are as follows:(1)the salt-lake brine was treated via flocculating and adsorbing with active carbon,(2) the solution treated reacted with barium hydrosulfide,(3)the pH value of solution was adjusted to decrease the content of boron in production,(4)the in.

Researching the method and effects of Lithium Magnesium by bittens extraction liquid,sovled the difficults of low Lithium condition and prepared grade I Lithium Magnesium products,thus,it is possible that preparing Lithium Magnesium by bitterns in the field of technology.

The thesis is mainly intrducing the process and technology of Lithium and Magnesium, Saparated from bitterns and Analysed the key factors, conclueded the rate of solvent extraction, the optimum condition of extraction was choosed.
