Fundamental Improvement In The Tribocharging Separation .

Electrostatic separation has great potential as a fine particle separator (i.e. < 1mm) in industrial minerals processing application, especially in arid areas where water supply is limited. In the current study, particle tribocharging kinetics was evaluated using a model system comprised of copper, pure coal, silica and ceramic.

US6098810A - Flotation process for separating silica from feldspar .

The process first separates silica from feldspars, preferably feldspar, in concentrate and tailings fractions, respectively, and subjects the concentrate and tailings fractions to magnetic separation to remove the magnetic impurities. As used herein, "magnetic impurities" refer to heavy minerals that demonstrate magnetic.

Triboelectric effect - Wikipedia

Amber, for example, can acquire an electric charge by contact and separation (or friction) with a material like wool. This property was first recorded by Thales of Miletus. The word "electricity" is derived from William Gilbert's initial coinage, "electra", which originates in the Greek word for amber, ēlektron. The prefix tribo-.
