A broad spectrum of the subject from basic research to plant applications has been covered. Flotation and hydrometallurgy have attracted a good deal of interest in view of their growing importance in the processing of complex ores. Physical methods including magnetic and gravity separation techniques have received attention in the processing of tantalum, niobium and tungsten. In addition, a set of papers is devoted to expert systems and their applications in mineral processing plants.
