Flotation columns: Getting the most from fine

Flotation columns comprise a tall tank, in which the separation between froth and pulp occurs, an aeration system, a pulp level control system, a wash water system, a discharge barometric leg and a set of control instruments, besides pipe connections for feed, concentrate and tailings. Figure 1 illustrates a typical column. Figure 1.

Flocculation and Sedimentation of Bauxite

Flocculation and sedimentation of fine bauxite from flotation tailing pulp were studied using different flocculants to investigate the possibility of its application. The results of this investigation indicate that inorganic flocculants of PAC and PAS have better flocculating effect than organic flocculants of PAM1# and PAM2# when keeping the original pH (7.5~8.0) of tailing pulp, however its

Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water
