This short communication presents residence time distribution (RTD) measurements and modeling in a 16 m3 Siemens flotation cell, as the first RTD characterization in an industrial-scale pneumatic cell. The Siemens cell was installed as a pre-rougher machine in a Cu-Mo selective plant. This plant recovered molybdenite as Flotation Plant. The actual process of concentrating the minerals by flotation is but one of a sequence of operations, The labor, of course, will vary with the size of the plant. At one plant consisting of 60 cells, two men per shift operate the entire plant, equivalent to a cost of 1¼c. per ton.Flotation 911 Metallurgist

This paper presents a characterization of the different minerals recovered along industrial flotation circuits. Plant sampling campaigns, performed in a copper industrial concentrator in Chile, provided the data for the study. Two rougher flotation banks consisting of cells of 130 m 3 and 300 m 3, were evaluated.Mineral carrying rates across the pulp-froth interface in the range of 1.4-3.2 tph/m 2 and bubble surface coverage between 7 and 22 %, have been determined in large rougher flotation cells (100DESIGN OF FLOTATION CIRCUITS WITH CONVENTIONAL FLOTATION CELLS
