Funding to extract rare earths from coal. Rare earth elements are vital in the production of various types of high tech electronic equipment, including computers, smartphones and rechargeable batteries, but currently, 85% come from China. In addition, a higher concentration of rare earth elements are found in the poor quality coal,...

Japanese Firm to Extract Rare Earth Elements from Red Mud

Japanese Firm to Extract Rare Earth Elements from Red Mud The Jamaica Bauxite Institute (JBI) has signed a Memorandum of Understanding (MoU) with Nippon Light Metal of Japan, for the establishment of a pilot project to extract earth elements from red mud.

From coal, a new source of rare earths

Although rare earths are much more concentrated in acid mine drainage sludge than in the acid mine drainage, it may be more economical to extract the rare earths from the acid water than the sludge.

Complete Rare Earth Extraction Plant EquipmentMine

Complete Rare Earth Extraction Plant Equipment from a 5 to 10 tons per hour plant to process a rare earth metal concentrate. Items include skid mounted ball mill, Outotek magnetic belt separator, (2) Eriez CrossFlow separators, (3) banks of flotation cells, rotary dryer, supersack filler, and lab equipment.

Extraction and Recovery of Cerium from Rare Earth Ore by ...

Rare earth elements are widely found in many minerals, some of which, such as bastnaesite, monazite, and xenotime, are of great commercial value. Cerium (Ce) is the rare earth element with the highest content in light rare earth ore. Solvent extraction is the most effective and efficient method to recover and separate Ce from other light rare earth elements.
