Medallion's Metallurgical Tests Yield 91% of 10 Rare Earth Elements

Medallion Resources Ltd. (TSXV:MDL) announced that bench-scale metallurgical tests from by-product monazite sand recovered an average of 91% of 10 rare-earth elements and yielded a mixed rare-earth concentrate, containing 47% rare-earth oxide (REO) content. This high-purity concentrate is anticipated to be suitable for input into standard commercial rare-earth refineries or separation plants.
As quoted in the press release:

The tested by-product monazite sand sample contained approximately 47% rare-earth oxide (REO) content – with the rare-earth elements found predominately in the mineral monazite, a rare-earth phosphate. The test recovery percentages for the ten commercial rare-earth elements (and yttrium) ranged between 72% and 96%, with a weighted average recovery of 91%. Although this is an excellent recovery percentage, the Company is confident that further metallurgical testing can improve the recovery values to even higher levels and also optimize individual rare-earth element recoveries based on market pricing.
Significantly, the tests showed that the magnet-related elements (Nd, Pr, Dy, Tb) are critical to the project’s economics, as in this case they represented 86% of the value of the concentrate, using current standard Chinese FOB prices (source: Asian Metal August 2015).
