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.


Plasma recycling claims to be able to tackle all these kinds of waste safely and with little or no harm to the environment. What is plasma arc recycling? To answer that question, it helps to understand how plasma recycling differs from conventional incineration: simply tossing waste on a fire.
