In the iron ore industry, froth flotation is either used as a primary method for concentrating iron ores, such as Cleveland-Cliffs’ operations in Michigan, United States, or in combination with magnetic separation, which has become a popular practice in Minnesota, United States[1].

Schreiber says that process control in a flotation plant can be onerous with controlling slurry level and froth proving inherently difficult in a row of flotation cells. “The slurry level in any cell affects the driving head in adjacent cells and this can easily create unstable control conditions.

Flotation is an incredibly robust and versatile process that is well accepted around the world. It works equally well on mixed sulfide, oxide, silicate and other ores. It relies on generating a population of bubbles of suitable size that can carry the hydrophobic target mineral (usually but not exclusively sulfide minerals) up to be recovered.

The flotation phases employ conventional large-size mechanical cells, in addition to flotation columns. This process uses starch (depressant) and amine (quartz collector) as reagents to promote the separation of the contaminant mineral (quartz) from the …

Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution. The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a froth.

Copper ore may be separated from crude ore using a flotation pro-cess that takes advantage of the physical (as opposed to chemical) properties of small copper ore particles. To maximize the copper yield, pH control is necessary in the flotation tanks. The copper flotation process Crushed ore, along with water and lime slurry, is fed into a …
