Jameson Cells in Coal Flotation The Australian Coal Industry served as a rigorous testing ground for the Jameson Cell in the 1980s culminating in the first full scale Jameson Cell coal installation at Newlands in 1990. The Jameson Cell is now the industry standard with over 100 coal cells installed by 2010 in Australia alone.

Get PriceThe operational proof-of-concept for the flotation cell class of 500 m3 and larger is discussed in this paper. Two different sites are used as case studies and metallurgical and hydrodynamic performance is evaluated as the means of comparison. Frother selection criteria are also discussed and a redesign on standard practices for scaling up to full-scale from lab and pilot-scale is proposed.
Get PriceFeb 08, 2019Although CFD has been used for flotation equipment design, the literature about its use for the scale-up of flotation cells is scarce. An example of the use of CFD in flotation equipment design and flotation modelling is the work of Koh et al. [90], who developed a 3-D CFD flotation model.
