The equipment is used for the high temperature smelting of ores taking use of the microwave's selectivity and heating 

characteristic from the inside to the outside. Its most outstanding feature is the smelting temperature is low, which can 

save the heat energy needed by the high temperature furnace slag melting in the traditional smelting process. It has the 

advantages of reasonable structural design, strong operability, high production efficiency, continuous production, low cost 

and high recovery rate.     http://www.microwave-world.com
