摘要： LiFePO4 or LiMnxFe(1-x)PO4-containing black mass or a material that is derived from LiFePO4 or LiMnxFe(1-x)PO4-containing black mass is acid baked or salt baked and leached with water to extract Li+, one or more types of non-lithium cations, and SO42−. A basic reagent is added to the acidic leachate to precipitate salts of the non-lithium cation(s) to form solid leachate tailings. After separating the lithium-enriched liquor from the solid leachate tailings to produce a product liquor, the product liquor is optionally contacted with a precipitation agent in order to precipitate product Li2CO3 or LiOH.

摘要： Methods for extracting lithium from brines may include evaporating at least a portion of a brine using a number of one or more solar evaporation ponds to form a first slurry. A first solid may be separated from the first slurry and combined with an amount of a first precipitation additive to form a second slurry. A first liquid may be separated from the second slurry and at least a portion of the first liquid may be evaporated in a solar evaporation pond to form a third slurry. A second liquid may be separated from the third slurry and combined with an amount of a second precipitation additive to form a fourth slurry. A second solid may be separated from the fourth slurry and rehydrated, forming a fifth slurry. About 90 wt % or more of a salt in a solid product separated from the fifth slurry may be lithium carbonate.

摘要： A process recovers metals from a black mass. The process includes the following steps in the following order: step (a) providing the black mass, which comprises Li; step (b) adding water to the black mass and creating a suspension of the black mass in the water; step (c) dosing ozone as an oxidant to the suspension while stirring the suspension; and step (d) filtering and separating a filtrate containing LiOH dissolved in water from a Li depleted residue of the black mass. In step (c), the suspension is stirred with a shear rate greater than 11000 s−1 within the suspension.

摘要： The method for recovering lithium hydroxide from a lithium secondary battery allows a powder comprising lithium and valuable metals to be prepared from the lithium secondary battery. The powder is reduced to form a preliminary precursor mixture including a preliminary lithium precursor and valuable metal-containing particles. The preliminary precursor mixture is primarily washed with water (H2O) to generate a lithium precursor aqueous solution and a precipitate. The lithium precursor is recovered through solid-liquid separation of the lithium precursor aqueous solution and the precipitate. The lithium precursor is recovered, through additional washing and solid-liquid separation, from the precipitate obtained through the solid-liquid separation. A calcium compound is added in the primary washing operation or the additional washing operation. Therefore, a highly-pure lithium precursor can be obtained without a complex leaching process and additional processes resulting from a wet process of an acid solution.

摘要： The present disclosure relates to a method of producing a lithium concentrate from a calcined ore comprising spodumene particles and other mineral particles. The spodumene particles are selectively screened from the calcined ore to obtain the lithium concentrate. The spodumene particles have a beta crystal structure and the other mineral particles have a crystal structure substantially similar prior to and after calcination.

摘要： A gas injection module for separating minerals is disclosed. The gas injection module injects a gas to a supersaturated solution containing at least one mineral. The gas injection causes at least a portion of the supersaturated solution to crystallize. The supersaturated solution can be created using a clay, such as a raw Zeolite clay and a liquid (e.g., water). The Zeolite clay can contain lithium and be crushed before it is mixed with the liquid. A non-crystallizing portion of the supersaturated solution can be recirculated within the gas injection module for additional exposure to the gas and/or be processed by a reverse osmosis system.
