Role of frothers in column flotation of coarse phosphates
2003年11月1日 The use of column flotation has become increasingly popular. Although normally used for the flotation offline particles, column flotation was successfully used by the University of Florida for the flotation of phosphate from coarse feed (0.85 × 0.42 5-mm), fine feed (0.425 × 0.106-mm) and even unsized feed (0.85 × 0.106 mm). The application of

Comparative analysis of dolomite/francolite flotation
1996年8月1日 The results of bench-scale testing of five flotation processes for the separation of dolomite from phosphate are discussed. Each process is compared in terms of phosphate recovery, MgO content of the concentrate and reagent consumption. Water quality was found to play a major role in the performance of these processes. The effect

SELECTION OF MECHANICAL FLOTATION EQUIPMENT
2021年6月24日 Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry , the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower, , and pumped down the
