The Flotation Cell is aerated to produce bubbles and agitated to keep the solids particles in suspension in the pulp. A flotation cell is an appliance in which froth flotation of ores is performed. It has provision for receiving conditioned pulp, aerating this pulp, and for separate discharge of the resulting mineralized froth and impoverished ...

The assessment of mineral surface hydrophobicity at the industrial scale is a challenge. In some industrial situations, such information is indirectly obtained from other proxy variables. A well-known example of this is observed in the Cu-Mo selective flotation operation, where sodium hydrosulphide is used to change the redox potential and, …

In contrast, other published papers reported that better Cu flotation efficiency was achieved due to enhanced pyrite depression in the presence of thiosalt and calcium ion impurities . Bıçak et al. also found that the presence of dissolved metal ions, such as Cu 2+ and Pb 2+, increased the flotation rate and recovery of sphalerite. Thus, …

1. Introduction. Mining activities consume billions of m 3 of water annually. The water withdrawn by mining industries could achieve 17 m 3 per ton of processed ore while the water consumption required in processing varies between 0.34–6.27 m 3, according to data from 359 industries reports [1].Seeing that the world iron ore …

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 …

The flotation separation of Cu–Fe sulfide minerals at low alkalinity can be achieved using selective depressants. In the flotation system of Cu–Fe sulfide minerals, depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector. This review summarizes …

The results demonstrated that mild steel rods produced a higher recovery of Cu, Ni, and pyrrhotite, meanwhile a higher Fe amounts extracted by EDTA and a lower Do level than stainless steel rods. The effect of collector addition site was different for two kinds of medium. For mild steel rods, collector added in cell produced a higher Cu recovery.

Low-cost and environment-friendly green froth flotation modifiers of plant origin, such as guar gum, carboxymethyl cellulose (CMC), and starch, have been used in flotation of some sulfide and non-sulfide minerals. Certain green modifiers may be used as dispersants, flocculants, depressants, or activators. The functions of green modifiers in …

Abstract: The main problem in the flotation of Cu-Mo sulfide ores in seawater is poor floatability of molybdenite at pH>9.5. Froth stability plays a very important role in determining concentrate grade and recovery in flotation operations and in this paper both floatability and frothability have been tested. The frothability have been studied ...

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …
