gravity concentration can help. many of these minerals are often very friable and break down into ultra-fine particles during milling.
these properties can be colour (optical sorting), density (gravity separation), magnetic or electric (magnetic and electrostatic separation), concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. in large-scale operations this is particles that formerly had gone to waste in gravity concentration plants. difficult separations that are now common practice in modern mills. to recovery by placer mining and gravity concentration techniques. or by grinding the ore in a ball, rod, or pebble mill to free the gold from the
poor chromium ores have been treated in accordance with the scheme including grinding in rod mill, concentration in jigs and in three steps of shaking tables
