Evaluation of Maghemite-Rich Iron Oxide Composite Prepared from Magnetite as Adsorbent for Gold from Chloride Solution

The capacity and effectiveness of a composite magnetic iron oxide, consisting mainly of maghemite ( γ Fe 2 O 3 ) , prepared by oxidation of synthetic magnetite at 350°C have been evaluated. X-ray diffraction analysis of the synthesized product indicated an iron oxide with 44%, 33%, and 23% of maghem...
