Thermal plasmas in material processing

Plasma torch is a device which produces a plasma beam in the form of an electric arc at atmospheric pressure. The plasma torch of conventional design consists of a tungsten rod cathode and a water cooled copper anode, shaped in the form of a nozzle (figure 2). The two electrodes are separated by an insulator which also has an inlet for plasma gas. When a gas is introduced in the electrode gap

Plasma gasification - Wikipedia

Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide.A plasma torch powered by an electric arc is used to ionize gas and catalyze organic matter into syngas, with slag remaining as a byproduct. It is used commercially as a form of waste treatment and has been tested

Plasma power: increasing precious metal yields

While only 34g of gold had been found per metric ton before the application of the RF plasma torch; the new technology uncovered an astonishing 500g of the precious metal for the same weight of complex ore. When scaled up to production level, this could equate to roughly $2m-$4m of income every quarter, according to TPT managing director Tony Heo.
