Design And Performance Aspects Of Coal

Design And Performance Aspects Of Coal Figure 1 Flotation triangle showing the factors affecting performance. The Jameson Cell technology was first introduced in the late 1980s to overcome the design and operating inadequacies that were being experienced with column and conventional flotation cells. FromFigure 1 Flotation triangle showing the factors affecting performance. The Jameson Cell technology was first introduced in the late 1980s to overcome the design and operating inadequacies that were being experienced with column and conventional flotation cells. FromThe major operating difference between column and mechanical cells is the lack of agitation in column cells that reduces energy and maintenance costs. Also, it has been reported that the cost of installing a column flotation circuit is approximately 2540 less than an equivalent mechanical flotation circuit Murdock et al., 1991 .a new flotation cell that offers high capacity, reduction in both size and horsepower and superior metallurgical performance. This leap in technology is based on the application of flotation fundamentals. While column flotation will still be a requirement for some applications, this new approach offers a flotation alternative that
