In a cost breakdown of large flotation cells by Rinne and Peltola [15], it was found that about 68% of the cells' total operating cost comes from energy consumption. The power draw of the mixing mechanism in a mechanically agitated flotation cell is proportional to a third of the impeller rotation speed [15].

01 What is a Flotation Cell? Back. Flotation cell is the equipment that can realize froth flotation and separate the target minerals from the ore. Nearly 2 billion tons of ore around the world are separated through the froth flotation process. Flotation cell is suitable for separating non-ferrous metals, ferrous metals, precious metals, non ...
Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

Flotation process within a column. Typically, columns are suitable for ores with a particle size bellow 150 µm. Larger particles tend to be too heavy to be kept in suspension. This size limit may vary depending on the ore density. Lighter ores, such as phosphate, are amenable to column flotation at larger particle sizes.
In a typical plant, the mechanical cell tanks are arrangedinaseriescalledabank.Thenumberofcells in a bank varies depending on cell size, application and plant circuit conRguration.
