14.09.2011· Key variables and considerations in the control of flotation. Froth flotation is a three phase separation process for complex ores based on the manipulation of the difference in hydrophobicity of the solids. Suspended, hydrophobic metal-rich particles are contacted with, and subsequently combine to, air bubbles — whilst the more hydrophilic gangue particles sink and are recovered to the tails stream. The valuable-mineral loaded bubbles report to a froth …

Froth flotation is one of the most versatile and flexible of all mineral separation processes. Reasonable results are fairly easy to obtain but outstanding performance from a circuit requires constant attention and good understanding of the process and ore. Some of the variables that affect the operation and control of a flotation process are classified as follows:

01.03.2014· This experimental work on sphalerite flotation investigated the effect on flotation performance of three particle size fractions, namely, coarse (d 80 = 100 μm), medium (d 80 = 39 μm) and fine (d 80 = 15 μm), bubble size distribution, superficial air velocity, and collector dosage. Bubble size distributions were characterized with the image analysis technique. The two-phase (liquid–gas) …

Frothers are very important reagents playing a multiple role in flotation of particulate matter. The frothers facilitate formation of either foam or froth and favourably modify the structure of films between bubbles as well as solid particles and bubbles [1–7]. Frothers also interact with collectors

of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles. Within this general macroscopic view of the flotation process as a whole, several distinct micro processes can be identified. Each of these plays a role in determining how individual solid ...
