This issue can be prevented or reduced by adding appropriate froth crowding to reduce the surface area and thus effective froth volume required. This will allow a relatively deep and stable froth to be maintained even at the rear of the flotation bank

Comparative evaluation between mechanical andmatic Conventional flotation technology employing mechanical machines and columns in the iron ore industry mechanical cells and columns are not effective for collecting lead, nickel and zinc, for the precious metals platinum, gold, and silver
FLSmidths other major innovation is its Hybrid Energy circuit configuration, which addresses a problem of inconsistency in float cells. Because some ore is being recovered in each cell of a circuit, the mineralogical characteristics are changing from cell to cell but the cell design itself is not
During the past decade significant efforts have been made to develop and improve flotation equipment. Large-scale systems and the utility of column flotation cells have been established. Manufacturers improvements in flotation equipment have been focused on larger units (on the order of 140 cubic meters), but markets for large flotation cells may be limited because of short-circuiting problems and because many operations are small (less that 1,000 tons per day), and the volume of the flotation cell may not be the dominant factor
In addition to the jellyfish-hunters, comb jellies come in a wide variety of other body types and ecological niches. One spherical species, known most excellently as the sea gooseberry, dangles long tentacles that snag smaller prey such as copepods. Then there are some that look a bit like biplanes, known as lobates, which cruise along like crop dusters, according to Haddock. Instead of dangling their tentacles, theirs are situated along their mouth to snag prey and ferry it inside. Still other species have adapted their cilia into serrated teeth. "They have this whole field that looks almost like a velcro strip or something, with all of these teeth pointed in the same direction," said Haddock. "And they can actually ratchet themselves over and bite off chunks of other jellies that they've captured."
Mechanical cells usually consist of long troughs with a series of mechanisms. Although the design details of the mechanisms vary from manufacturer to manufacturer, all consist of an impeller that rotates within baffles. Air is drawn or pumped down a central shaft and is dispersed by the impeller. Cells also vary in profile, degree of baffling, the extent of walling between mechanisms, and the discharge of froth from the top of the cell
