Title: The Economics of the Search Minerals Direct Extraction Process for Rare Earth Element Recovery
Abstract: The Foxtrot deposit of Search Minerals contains a range of rare earth element containing minerals including allanite, fergusonite and bastnasite. The Search Minerals Direct Extraction Process for treating these minerals involves coarse crushing of the ore to-6 mesh (3.45 mm), acid treatment at 200 °C in a novel reactor configuration, water leaching, various purification steps to reject iron, aluminum and uranium/thorium (present in small amounts) and finally precipitation of rare earths as a oxalate and calcination to form a mixed rare earth oxide product for refining. The economics of the process are presented.
