There are no primary mine sources for Scandium and the present supply is from stock piles and byproducts. Scarcity of reliable supply and high production costs hinders the use of Scandium in high end technologies. In this report, we discuss the development of a recovery process for scandium from the red mud. A recovery process based on roasting, leaching and selective precipitation is designed from available literature and optimized by lab scale experiments. A detailed economic analysis of the process using Monte Carlo simulations is presented. Uncertainties associated with the operating conditions like commodity prices, market etcis accounted for in this approach. The analysis shows that the developed process is profitable even at the lowest historical price of Sc 2 O 3. The cumulative NPV cost profiles generated correlating the historical prices of different purity Sc 2 O 3 (99 -99.99%) also were positive indicating that the developed process has a large scope in terms of commercial feasibility. © 2019 Elsevier Ltd.
