Rare Element Resources’ Proprietary Process Increases REO Concentrate to 90+%

Rare Element Resources Ltd. (NYSE:REE, AMEX:REE, TSX:RES) announced updates in regards to their proprietary process technology which focuses on the efficiency of rare earth recovery.

As quoted in the press release:

The new metallurgical process consists of Hydrochloric (HCl) acid leaching at moderate temperature, selective precipitation of rare earth elements (REEs) with oxalic acid, and calcination of REE oxalates at elevated temperature to produce a high purity mixed REO powder, with accompanying capture of kiln flue gases.

Rare Element Resources’ COO,  Jaye Pickarts, said:

We are extremely pleased with the development to-date of this exciting technology, and the potential benefits the proprietary process brings to the project and our customers. As we continue our lab scale testwork, the final results will support our upcoming definitive feasibility study, scheduled to start in mid-2013.
