The objective of this project is to develop and test an accelerated reactive carbonation process to enable improved mineral liberation, energy-efficient comminution, and enhanced separation of rare earth elements (REEs) from metamorphic ores containing bastnaesite and low-grade REEs bearing overburdens from Mountain Pass deposit.
Our team contributes on the techno-economic assessment (TEA), and process and economic modeling to support this effort including base case models and the proposed technology approach. A detailed computational process model will be developed to model performance under various operating conditions. The process model will include detailed material and energy balances of the main unit operations, namely (a) pre-treatment, (b) XRT sorting, © packed bed compression, (d) ball milling, and (e) flotation, as these are the main energy consuming unit operations.
Financial support for this project is provided by the ARPA-E MINER Program.
