: Plasma Arc Recycling of Precious Metals
Before the charge is introduced the furnace is preheated with the plasma to a temperature of around 1600°C. The plasma itself runs from a plasma torch, which is a water cooled metallic device that uses electrical energy to ionise gas and create a plasma arc. A plasma arc is a very intense, flexible heat source with a high temperature capability.

Melting e-scrap in an arc furnace | Gold Refining & Metal Extraction Forum
I have an arc furnace, capable of melting steel in seconds, and I was wondering if anyone had ever used such a furnace to melt down e-scrap so that all of the metal components form a bead. I have not tried this myself yet, but I do not know why it wouldn't work. Once I have metal buttons, I would use a cyanide bath to remove any precious metals.
