摘 要：<正> Since the low and medium grade oxide ores in the Main and Eastern Mining Areas at the Bayan OboMine have a high grade of Nb2O5 and large ore reserves and are rich in many elements,they are of greatervalue to use in development and recovery than other kinds of niobium minerals resources.The disseminationcharacteristics and processing properties of four types of niobium minerals are summarised and methods andresults of niobium mineral processing are also described.
