Apart from the entrainment of normal fine particles during flotation, clay minerals with a particle size normally smaller than 5 μm also undergo aggregation, generating aggregate structures which compound the entrainment problem. The aggregation behavior of clay minerals is attributed to their complex crystal structure, …

A 2 m diameter REFLUX™ Flotation Cell was fed at roughly 210 m 3 /h, equivalent to a flux of 1.9 cm/s, about twice the maximum rate used in conventional flotation cells. The coal feed slurry had 59–64 wt% head ash and nominal size range −0.100 mm (Sauter mean size 0.004 mm). The air, wash water and underflow rates …

The Direct Flotation Reactor (DFR) is a flotation cell that works on the principle of preventing the formation of a froth and froth slurry interface. Independent bubbles are removed from the collection zone in a gas phase/slurry phase. The flotation cell has a particle collection regime in the lower half of the vessel and the loaded bubbles are ...

Flotation tests were carried out in a 1.5 L lab flotation cell, at 150 g solids/L pulp density. Both flocculants were found to strongly depress coal flotation: the higher the flocculant dosage, the smaller the yield of the concentrate, higher its ash content, and lower ash content in the flotation tailings.

The flotation equipment with a downcomer such as the Jameson Cell has proven a significantly reduced residence time compared to conventional flotation cells (Harbort et al., 2003a). This design also increases the throughput through a reduced residence time while maintaining a small footprint ( Lawson, 2016 ).

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …

grades and the demand for improved flotation selectivity, all bring new challenges to minerals processing flowsheets. The Outotec Concorde Cell technology helps flotation circuits overcome these challenges and achieve improved efficiency in fine and ultra-fine particle recovery. Concorde Cell™ is an ideal flotation solution due to:

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 are mostly used to produce final grade concentrates because they are capable of high selectivity.

The methodology was based on using solid radioactive tracers, which was implemented in a two-dimensional flotation cell. The prototype cell represented a radial section of an industrial flotation cell (130 m 3) and was operated at steady state using a two-phase (air-water) system. The experimental tests consisted of adding a small …
