Flotation ore dressing Britannica
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water The flotation process was developed on a commercial scale early in the 20th century toJan 01, 2016 Since then, flotation has grown to be the prime mineral processing operation for both hard rock and coal separations Flotation is a separation process that has found prominence because of the need to treat complex or lowgrade ores where the average particle size for liberation is too small for efficient gravity separation or where the gravity Flotation ScienceDirect20 mesh is treated by 2stage flotation The flotation process uses hydrophilic or hydrophobic chemical reagents with aeration to separate suspended particles Phosphate rock mined in North Carolina does not contain pebble rock In processing this type of phosphate, 10mesh screens are used Like Florida rock, the fraction that is less than 10 1121 Phosphate Rock Processing
