FROM WASTE TO RESOURCE: EXTRACTING VALUABLE ELEMENTS FROM MINING SOLUTIONS USING BIO-BASED SURFACTANTS
Hogan, D., C. Boxley, and R. Maier. | Technical Sessions: Smart Mining: Resources for a Connected World, 24-27 Feb 2019, Denver, Colorado. p 135, 2019

Mining and mining-impacted solutions are often enriched in non-target metals during typical operations. These solutions must be treated or managed to ensure elevated metal concentrations do not pose human or environmental health risks. One management option is metal recovery using ion flotation. The green, bio-based surfactant rhamnolipid is known to be selective for valuable elements, including the rare earth elements, but has not been screened for efficacy in ion flotation of mining solutions. Rhamnolipids were examined as a collector in ion flotation for the treatment of mining solutions to achieve environmental and economic benefits.
