    1/1/2020· In this work, air recovery was used as a measure of froth stability to determine the flotation response of a copper tailings ore to changes in particle size distribution and superficial gas velocity. The system exhibited a maximum in air recovery, which correlates well with the local peak in dynamic froth stability presented in previous work.

    8/31/2017· An intermediate particle size of 74–250 μm resulted in the deepest and most stable froths. When a mixture of particle sizes was considered, a combination of approximately 55% fines −74 μm with 45% coarse particles at 250–500 μm resulted in the greatest recovery of coal to the concentrate.

    The particle size range of the flotation feed can be substantial because of ore hardness changes and changes in the operation of the grinding circuit. This can cause extreme variation in the performance of flotation even under constant operating conditions. Flotation operators must react and make changes without always understanding the primary cause for

  • 3 Factors Affect Froth Flotation Process? Mining-pedia

    Before the froth flotation operation started, the ore needs to be ground to optional particle size range. Generally it is ground to less than 0.1 mm. When the froth flotation is too coarse, the the particles size of ore (greater than 0.1 mm) will increase the exfoliation force of the ore due to the larger weight.

    Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is
