The Energy Cost of Extracting Critical Raw Materials from …
For tantalum, energy costs still represent only a small fraction of current commodity prices (10%). If energy prices were to double, energy costs would represent 50% of current commodity prices, putting the viability of its extraction at risk. Tailings 2 scenario would be unfeasible even at current energy prices.
