For froth flotation, an aqueous slurry of the ground ore is treated with the frothing agent. An example is sodium ethyl xanthate as a collector in the flotation of galena (lead sulfide) to separate it from sphalerite (zinc sulfide). The polar part of xanthate anion attaches to the ore particles and the non-polar hydrocarbon part forms a ...
An example of properly steamed milk, considered ideal to pour latte art The basic requirements for formation of foam are an abundance of gas, water, a surfactant, and energy. [ citation needed ] The steam wand of an espresso machine supplies energy, in the form of heat, and gas, in the form of steam.
Sea foam washed up or blown onto a beach. Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter (including proteins, lignins, and lipids) derived from sources such as the offshore breakdown of algal blooms.

In open-cell foam, gas pockets connect to each other. A bath sponge is an example of an open-cell foam: [not verified in body] water easily flows through the entire structure, displacing the air. A sleeping mat is an example of a product composed of closed-cell foam. [not verified in body] Foams are examples of dispersed media.

Historically the problems considered in the early days of soft matter science were those pertaining to the biological sciences. As such, an important application of soft matter research is biophysics, with a major goal of the discipline being the reduction of the field of cell biology to the concepts of soft matter physics.
