Data-driven system for intelligent monitoring and optimization of froth
From the production point of view, there are two dominant parameters to consider when evaluating froth flotation circuits performance: (1) the quality of the final product (i.e. concentrate grade) and (2) the recovery of useful component(s) in concentrate [15]. The purpose of this work is twofold: firstly, to construct a reliable predictive ...

Froth Flotation Process
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
