1 Froth Flotation Fundamental Principles

2009-8-27  The basis of froth flotation is the difference in wettabilities of different minerals. Particles range from those that are easily wettable by water (hydrophilic) to those that are water-repellent (hydrophobic). If a mixture of hydrophobic and hydrophilic particles are suspended in water, and air is bubbled through the suspension, then the hydrophobic particles will tend to attach to the air bubbles

Interactive effect of minerals on complex ore flotation:

2019-10-13  Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation of iron ores, magnesite ores, and scheelite ores

Chapter 15: Flotation of Copper-Lead-Zinc Ores

15.1.1 Hydrothermal Vein Deposits. The copper lead-zinc vein deposits are usually characterized by coarse-grained banded to massive aggregates of pyrite, galena, sphalerite and chalcopyrite. The bulk mineralogy is quite similar to that of strata-bound sulfide deposits, except that galena tends to be much more abundant in the vein deposit.
