CFD Simulation Research on Fluid Dynamics of Flotation Machines
With the rapid progress of computer science and technology, the computational fluid dynamics (CFD) simulation technology, which has gradually emerged and developed since 1960s, makes it possible to research the flotation equipment, a kind of complex three-phase mixing equipment, by the computational fluid dynamics method and Advanced flotation controllers based on froth image analysis have been developed in recent years. Machine vision can, for example, determine some characteristics of the froth surface at the top of a flotation cell, such as the number of bubbles, bubble size, bubble shape, density, speed and stability (Fu and Aldrich, 2019).Modelling for froth flotation control: A review ScienceDirect

A Review of Flotation Physical Froth Flow Modifiers
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the Specifically designed to maximise fine particle recovery, the Dorr-Oliver flotation cell is the most energy efficient, technically advanced, forced-air flotation machine on the market. Its air dispersion capabilities exceed all competitive forced air designs an important consideration for fine particle recovery.Forced-air flotation cell FLSmidth

Coarseness of Particles in Flotation in Impeller-Type Cells
The flotation efficiency depends on a few variables. The particle size is one of the most important; for example, the rate of flotation is maximum for the particles ranging 10–150 \(\mu\ \) m. When processing some ores, increasing the coarseness of particles recovered by flotation enhances the recovery of useful component and reduces the cost The design of cell-based flotation circuits is often completed in two distinct phases, namely circuit structure identification and equipment sizing selection. While recent literature studies have begun to address the implications of stochastic analysis, industrial practice in flotation circuit design still strongly favors the use of deterministic metallurgical Minerals Free Full-Text Design of Cell-Based Flotation
