Abstract
A method for recycling metallic sludge material includes collecting and precipitating a metallic sludge, and dehydrating the metallic sludge into a dehydrated metallic sludge. The dehydrated metallic sludge is then heated to a temperature ranging from 550 to 850° C., in order to remove hydrogen materials form the dehydrated metallic sludge, and to convert the dehydrated metallic sludge into oxidized metallic particles. The dehydrated metallic sludge may further be crushed into small metallic particles, before heating the dehydrated metallic sludge. The oxidized metallic particles may further be heated to a temperature ranging from 1100 to 1600° C., in order to convert the oxidized metallic particles into a metal ingot.
