COLUMN FLOTATION. ABSTRACT. Industrial application of column flotation began in earnest in the early 1980’s, and is now accepted as a conventional application. For example, most of the world’s major copper producers use column flotation as the final stage of cleaning. In addition, the technology is common for final cleaning of zinc, lead ...

Aug 24, 2011 Ca (g/min cm2), the maximum solids concentrate rate or carrying capacity in column flotation, is expressed as the mass of solids from the overflow per unit of column cross sectional area. It can be measured for a given set of operating conditions by determining concentrate solids rate as a function of feed solids rate. Carrying capacity is expected to

As with a flotation column, the froth may be water washed meaning the contact cell can also be used as a cleaner cell. The contact cell is mainly used in rougher flotation circuits. It is compact, highly efficient, simple to operate, and has low energy and maintenance costs. There are a number of other benefits and capital savings that can be ...

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
