Wemco flotation cells are manufactured by Baker Process, which also makes Agitair cells and pyramid column cells. There are two major Wemco designs, the Wemco 1 + 1 design and new SmartCell design (Figure 12). The 1 + 1 design comes in cell sizes from 0.57 to 85 m3. The SmartCell design comes in sizes from 8.5 to 160 m3.
FL Dorr-Oliver Eimco pioneered the way for large cell technology. From its first Wemco 257m3 cell installed in 2003, to now even bigger 300m3 cells being installed in Chile. These 26 x 300m3 Wemco cells will be the first major installation of 300's for a new plant and the first used in rougher/ scavenger duty!

Dorr-Oliver Eimco Summary Dorr-Oliver Eimco is a global leader in process systems for the physical separation of materials and the treatment of water and wastewater. Dorr-Oliver Eimco products are used by industries world-wide in the production of minerals, chemicals, food, power and pharmaceutical products, and by municipalities to
All experiments were carried out using a fully automated, pilot-scale 0.8 m 3 Dorr-Oliver flotation cell. Bubble images were taken from multiple locations within the cell.
The largest mechanical flotation machines available today have unit volumes in the range of 38 to 42 m³ (1,350 to 1,500 cft). In fact, the motivating forces of increasing capital and energy costs and decreasing ore grades, which created the need for large flotation cells, not only still exist, but are becoming more critical.

High-efficiency and cost-effective classification . KREBS ® hydrocyclones have been the preferred separation technology in mining and industrial applications since the 1950s. Today's gMAX cyclones and revolutionary REFLUX Classifier ® and GradePro ™ Classifier continue that legacy, delivering optimum performance and sharper separations at high capacities.
The earliest application of CFD to understand flotation microprocesses was performed by Koh et al. [6], who studied bubble-particle collisions in mineral flotation cells.Closely following their pioneering work, Koh and co-workers published a number of papers in which they developed flotation kinetic rate model for lab scale flotation cells [5], [7], [8], [9].
