Abstract
Hydrometallurgical systems, methods, and compositions are described in which amine-based lixiviants are utilized in substoichiometric amounts to recover alkaline earths from raw or waste materials. The lixiviant can be regenerated and recycled for use in subsequent iterations of the process or returned to a reactor in a continuous process. Extraction of the alkaline earth from the raw material and precipitation of the extracted alkaline earth is performed in the same reactor and essentially simultaneously.
Claims14
A method for the recovery of an alkaline earth from a raw material comprising;
- providing a raw material comprising an alkaline earth to a reactor;
- in the same reactor, exposing the raw material to a precipitant, thereby generating an alkaline earth precipitate, and an extracted raw material;
- and
- separating the alkaline earth precipitate from the extracted raw material,
- wherein the method is performed in the absence of an added lixiviant.
