Texas Rare Earth Resources Corp.’s phase I metallurgical testing and characterization at its Round Top flagship project was completed by Mountain States R&D International, Inc. as of October 2011. Initial laboratory analysis and testing was completed under the direction of Dr. Roshan Bhappu, a world-renowned expert in metallurgical process development.
Phase I results confirmed earlier expectations of ore characterization that indicates simplistic rare earth element associations suggesting favorable metallurgical processing options. According to the test results, the rare earth elements (REEs) are finely disseminated throughout the rhyolite host rock.
Phase II testing has begun and is focused on gravity and flotation concentration testing, as well as diagnostic leaching tests.
