Multimetco has a patented process for reclaiming precious metals from the catalyst. The heart of the recovery operation is a plasma arc furnace.

The catalyst materials are fed into the plasma arc furnace. A 10,000 degree centigrade electric flame moves across the surface of the catalyst heating them to temperatures that range from 1,500 to 1,600 degrees centigrade. The plasma arc is moved above the molten bath to distribute the tremendously intense heat over the entire surface, keeping the bath fluid and providing a stirring effect, causing the precious metals to collect together and settle to the bottom of the furnace in a layer of molten metal.

The slag flows continuously from the furnace, is cooled, crushed and sold to steel manufacturers for use in manufacturing high grade steel. The precious metal alloy is tapped, cooled, milled, then refined into Platinum, Palladium and Rhodium.
