Flotation Machine - an overview | ScienceDirect Topics

Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%. The hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.

Eliminate Flotation Bottlenecks | E & MJ

Traditionally, mechanical flotation design has focused on the pulp zone or residence time, with little emphasis on the mineral’s froth phase. How it performs in the froth is critical—if the mineral doesn’t manage to travel up through the froth from the pulp and then from the froth surface to the launder, there is simply no recovery.

Froth Flotation of Iron Ores - sapub

In the reverse flotation of iron ores, froth washing was found effective in reducing the loss of FINE iron oxide particles to froth. It was reported that the cost of installing a column flotation circuit is approximately 25% - 40% less than an equivalent flotation circuit of mechanical flotation cells[60].
