froth flotation processfroth flotation process

Froth flotation method is used to separate particles based on the differences in the ability of air bubbles to selectively attach to specific mineral surfaces in a mineral-water slurry. A finely crushed ore is suspended in water and a blast of air is passed through the suspension. The wet particles to which air bubbles are attached float as a froth which is skimmed, whereas the particles to which air bubbles are …

froth-based modeling and control of flotation processes

froth-based modeling and control of flotation processes

Aug 01, 2008 · This paper discusses and illustrates a new method for froth-based flotation modeling and control that can be used as part of comprehensive flotation control systems. The new method is based on the causal process model predicting future froth appearances from the given values of manipulated variables and observed values of the process variables

Mar 27, 2016 · The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which are floated are sulphides of

flotation process in mining

Flotation is a mineral separation process done in the water medium. It is based on the difference in the surface properties of the mineral and gangue. The surface of the selected mineral is made hydrophobic (water repellent) by the use of selective reagents and these particles get attached to the air bubbles that are introduced in the system and collected as froth whereas the hydrophilic

froth flotation analysis of oxidized lead-zinc ore

froth flotation analysis of oxidized lead-zinc ore

Sep 24, 2019 · Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic,which is suitable for lead-zinc ore. But the flotation of oxidized lead-zinc ore is a difficult one. In the treatment of lead-zinc oxide ore, it is complicated to choose flotation reagent and process flow

froth flotation - an overview | sciencedirect topics

The froth flotation process is more than a century old and was developed over a long period of time [8]. It takes advantage of the surface chemistry of fine particles—if one particle’s surface is hydrophobic and another is hydrophilic, upon generation of air bubbles, the hydrophobic particles tend to attach to the air bubbles and float, allowing for a separation between particles in the froth and those in the main body …

how does pulp concentration and ph affect froth flotation

Sep 20, 2019 · In froth flotation process, the pH value of the pulp needs to be paid close attention to at all times. The pH value needs to be measured with a test paper every once in a while to ensure that the pH value remains at a stable value. And the pulp concentration and liquid level need to be stable, ensure scraping, foam to scrape out the full plate
