Designing the number of flotation cells of Nochun copper mine based on the ideal flow pattern
Abstract:
Flotation circuit design including the number of cells and their arrangement in terms of series and parallelism to achieve maximum recovery of important issues in mineral processing plants Is. Most factories use past experiences and predefined patterns for design. In this study, achieving the piston flow pattern was considered as a reference and pattern and the resulting retrieval was used to calculate and design the number of primary cells (raffer) of the flotation circuit of the copper ore ore of Nochun mine. In the kinetic study of flotation of the mine sample, the kinetics constant (k) and the recovery at the extreme ( ∞ R) are equal to 0 / 13 (min / 1) and 96, respectively. / 88% and retention time was 28 minutes. By modeling this flow with a common pattern in mineral processing plants and according to the plant capacity (180 cubic meters per hour) flotation unit in Three parallel lines consisting of 7 series cells were designated as raffer. Thus, with 21 cells with a residence time of 4 minutes each and a volume of 4 cubic meters per cell, the overall recovery of 94 / was 34%. This value corresponds to the recovery from a laboratory cell with a retention time of 28 minutes that follows the piston flow pattern.
