The slurry is mixed up with chemicals in a conditioner and its pumped into the flotation cell. The flotation encounters as the air fed into the flotation cell is dispersed into the little bubbles with the rotor and stator and the adhesive force attracts the hydrophobic minerals and air bubbles together in the slurry.

MODEL BASED PREDICTIVE CONTROL OF A ROUGHER

The rougher otation circuit layout is shown in Figure 1, whose instrumentation considers Courier analyzers for feed, general, and concentrate grade. Additionally, PI level controllers are considered. The manipulated variables are the pulp level references, the measured disturbances are the feed ow, chemical reagents, and feed mineral grade.

Jun 21, 20130183;32;The remaining un floated mineral slurry will be discharged as tailings. Most flotation circuits include an initial stage of rougher flotation, tailed by a scavenger stage of flotation in order to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5 15 weight percent of the ore feed.

Froth Flotation Chemicals Market Growth, Trends, and

Flotation of various minerals, such as feldspar, quartz, calcite, potash, barite, phosphate, fluorspar, etc., is carried out using the chemicals. Direct and reverse flotation are the two flotation methods, depending on the attachment manner of the mineral. Froth flotation chemicals play a major role in the mining and processing of mineral ores.
