  • Plasma power: increasing precious metal yields from ...

    Apr 01, 2014  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.

  • PLASMA SMELTING OF UNCONVENTIONAL ORES AND MINE

    The plasma furnace consists of a refractory lined steel vessel, which is water cooled in the roof and upper shell areas, and with either a graphite electrode or a water cooled plasma torch as the plasma device, which is inserted through the furnace roof. The molten bath forms the anode of the circuit and the plasma device acts as the cathode.

    Sep 24, 2014  There is much concern in routine gold refining in a controlled furnace about volatizing the gold into vapor or coating the inside of the furnace. Taking the process to a higher level, forming a plasma, would introduce a larger realm of potential losses versus any practical expectation of increased recovery. That's an opinion.
