REV-C: Rare Earth Element Value Chain Optimization Tool

The Challenge

Navigating the rare earth element (REE) market is challenging due to imbalances in REE abundance and value. For instance, while cerium and lanthanum are plentiful and relatively inexpensive, REEs used in permanent magnets, like neodymium, praseodymium, and dysprosium, are both rarer and higher in demand. This imbalance complicates supply and demand dynamics, particularly for industries attempting to apply abundant REEs to improve mining economics. As new applications for these elements are researched, understanding their potential impact on individual REE commodities is crucial but remains largely unknown.

How It Works

The REV-C tool models the complex interactions within the rare earth element value chain. Using a system dynamics approach, REV-C forecasts market size, pricing trends, and potential supply impacts to aid decision-making for new applications. When an industry considers REE use, the model can identify which form (such as intermediate, oxide, or metal) best suits the end-use application, based on real-time supply and pricing forecasts. For instance, when evaluating the aluminum-cerium (Al-Ce) alloy, the model identifies cerium oxide as the most sustainable choice due to its larger market size, despite cerium carbonate's lower initial price.
