    Lithium Li is the most valuable metal in spent lithium LiFePO4 batteries, but its recovery has become a challenge in electronic waste recovery because of its relatively low content and inconsistent quality. This study proposes an acid-free and selective Li process to successfully achieve the isomorphic substitution of Li in LiFePO4 crystals with sodium Na. The ...

    Bacterial Extraction of Phosphorus from Iron Ore

    Some ore sources have significant levels of phosphate minerals that are difficult to remove, and so use of ore from these sources requires the and steel plants to remove the excess from the molten metal. If can be removed from the ore at the ore concentrator, the value of the ore concentrate can be increased.
