Designing flotation cell

Aug 26, 2021

Engineering and Science in Flotation Cell Design. In the 1990s round flotation tanks were introduced as a result of the. lower fabrication costs for larger cells. It was soon observed that round tanks. held a number of further advantages over the traditional rectangular cells, such. as better hydrodynamics, lower costs and reduced footprint per
