Spinel Manganese Oxide as a Selective Adsorbent for Cobalt Recovery from Metal-Rich Waste Streams
A spinel phase of MnO2 (“λMnO2”) was synthesized and characterized as a sorbent for cobalt (Co) and 5 other metals common to Co-rich waste streams (Ba, Ca, Mg, Ni, and Sr). Sorption was characterized in both single and multi-metal solutions to understand potential applications for metal recovery under realistic condi...
