    2011-12-8  cle size studies of ores of Bihar as applicable in general to the mining and mineral industries is discussed. It is well known that a decrease in particle size of matter implies an increase in surface area for the same volume of matter. On breaking a mineral into two parts, new surface is created without changing the volume of ore/mineral.

  • Production and Processing of Fine Particles

    Successful preconcentration of ores grading 0.9% Nb 2 O 5 to products of 6 to 12% Nb 2 O 5 is possible at particle sizes down to 10 μm provided that size-classified feeds as well as reagents are used to modify the behaviour of particles in the concentrating film. The high degree of gangue rejection suggests that the method could possibly be combined with flotation to circumvent some of the selectivity problems in an

Sadawy (2013) reported that Fe grade was reduced with both decreasing particle size and increasing magnetic field intensity (0.2–1.4 T) for dry magnetic separation of Aswan iron ore. This ore was classified as oolitic, and comprised hematite, goethite, quartz and kaolinite.
