cost of mechanical cells vs flotation columns

Column Flotation Cells - 911 Metallurgist

2016-2-28  Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns

Flotation Cell - an overview ScienceDirect Topics

The 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 25–40% less than an equivalent mechanical flotation circuit (Murdock et al., 1991).

Column Flotation - SGS

Flotation columns differ dramatically from mechanical flotation machines in . several ways: • there is no mechanical agitation/shear • the cell is relatively tall and narrow • gas bubbles are generated by sparging • froths typically are deeper, and wash water typically is liberally applied to the surface of the froth.

Column and Contact Cell Flotation SGS

Column Flotation. Flotation columns work on the same basic principle as mechanical flotation cells – mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic (water-repellent) by conditioning with selective flotation

advantages of column flotation over mechanical cell

The advantages of pneumatic flotation cells over mechanical flotation cells, as well as flotation columns, for the flotation of sulfide ore were demonstrated. Test results indicated that the Cu grade and recovery for concentrates obtained when using the pneumatic flotation cell were 1% to 2% and 4%, respectively, higher than those obtained when
