GCC optimization - Gentoo Wiki

-ftree-vectorize is an optimization option (default at -O3 and -Ofast), which attempts to vectorize loops using the selected ISA if possible. The reason it isn't enabled at -O2 is that it doesn't always improve code, it can make code slower as well, and usually makes the code larger; it …

Model Predictive Control for Froth Flotation Plants

The optimization horizon should be long enough in order to cover the time constant of the process. Since a flotation circuit is a rather slow process, the sampling time of the controller can be chosen such as to allow enough time in order to perform the computations for solving the optimization problem.

Flow of Flotation Feed Process in Mining | FLEXIM Meters

Overview. The hydrometallurgical processing of copper sulfide ore - as well as other minerals, such as iron ores, etc. - starts with crushing it into a fine powder and then separating the valuable minerals by means of a flotation process. Volumetric flow measurements are required to maintain a proper process control and efficiency.

Floatation on the other hand by definition is the act, process, or state of floating or of causing or allowing something to float. In order to gain more floatation minimize the ground bearing pressures to increase the buoyancy or floatation of the machine. The heavier the machine the more ground contact area is needed to carry that load.
