Extraction of minerals from unconventional waste sources
Abstract
Systems and methods are provided for multiplexed extraction of target minerals from a variety of separate or combined desalination brines and/or wastewater sources. The use of multiple pretreatment, extraction, and posttreatment apparatuses with intelligent, directed flow control can allow for a single system to extract multiple target minerals. Improved extraction methods including zwitterionic simulated moving bed chromatography with target-specific zwitterions can allow for improved extraction efficiency and recovery rates with a dramatically reduced environmental footprint compared to existing methods.
