Flotation, which used "frothing" machines to mix air bubbles with oil and finely ground ore, emerged by the early twentieth century to do the same thing. Miners then shipped the resulting concentrates to smelters for further processing. Miners used chemicals, heat, and electricity to process more complex metal and mineral compounds.

A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a piece of equipment designed to assist a wearer to keep afloat in water. The wearer may be either conscious or unconscious.
In the late 19th century, due to the increasing demand for metals, the resources of coarse-grained lead, zinc and copper sulphide ore that could be re-selected gradually decreased. In order to select fine-grained ores, flotation was clearly put forward as a beneficiation method . ... With the increase of the volume of flotation equipment and ...

Kapok's use as a filler for personal flotation devices lost favor once new fibers began being mass produced. For instance a regenerated cellulose fiber known as rayon was being spun as early as 1901. Other manufactured materials were helping to evolve life saving equipment and clothing, but most were decades away from mass production.
