摘要：

Flotation cells have an operating gas rate range. A method to define the range objectively using the relationship between gas holdup and gas rate (epsilon(g) vs. J(g)) is introduced. This is made tractable by the necessary sensors becoming available. Examples in three cell types at three plants illustrate the procedure. (c) 2005 Elsevier Ltd. All rights reserved.
