Fig. 10,Fig. 11 show the grade of feed, dropback and tailing samples as a function of particle size for various superficial velocities on Day 1 and Day 2, respectively.Jameson cell Wikipedia,The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for

Greater recovery to the rougher concentrate for ORE 1 is due to better liberation of copper bearing particles (as shown in Section 3.2.1), i.e. in ORE 1, 63% of copper bearing particles have >70% liberation. In the case of ORE 2, only 49% of copper
