Study for Process Mineralogy of Refractory Rare Metals Ore
Rare metal ores have those features of high industrial value and bad performance in ore separation. Most of rare metals ores are with low grade of valuable components, rareness of useful minerals, complicated combination of associated minerals and high difficulty in separation and enrichment of minerals. For those single (Ta, Nb) or (Ta, Nb, Sn) ore occurred in granite and pegmatite,the ways of gravity separation and magneto electric separation toconcentrate (Ta, Nb) minerals are adopted. There are many mines being explored successfully both at home and aboard. While, for complex (Nb-Zr-REE) ores associated with Be and Ti minerals, they are commonly considered as rich rare metals ore but more difficult to process.One of rare metals mine in Inner Mongolia has the features as with large reserves and high grade of columbium and zirconium and accompanies with REE and beryllium, therefore with significant industrial value. After the utilization of research method of process mineralogy, detailed mineralogy research has been made on the rare metals ore. The test results show that there are abroad isomorphism replacements among such elements, such as Ti, Mn, Fe, Nb and Ta, between Be and REE in metallic oxide minerals of that ore, which makes the mineral composition of that ore extremely complicated. This research identifies clearly the mineral composition, and investigate at the technological property and the occurrence of those elements as Nb, Zr, Be and REE in the rare metal ore.The achievements of this research provide important mineralogy basis for ore dressing research of refractory rare metallic ores.
