The one major advancement has been the use of Column Flotation as a cleaner float cell in the copper industry (and a few other industries). It produces a cleaner product, and is more efficient as a cleaner cell, generally, than conventional flotation cells.
Solid-phase extraction (SPE) is a sample preparation process by which compounds that are dissolved or suspended in a liquid mixture are separated from other compounds in the mixture according to their physical and chemical properties. Analytical laboratories use solid phase extraction to concentrate and purify samples for analysis.

Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate).

The flotation experiments were carried out in a small laboratory column-type cell with fine bubbles with typical average diameter of about 150 mum. No wash water was used.
As with a flotation column, the froth may be water washed meaning the contact cell can also be used as a cleaner cell. The contact cell is mainly used in rougher flotation circuits. It is compact, highly efficient, simple to operate, and has low energy and maintenance costs.
