The invention provides a pollution-free reuse method for iron-based grinding waste, involving the technology of recycling economy, with special reference to the metallurgical industry, iron-based grinding waste green recycling technology. The present invention of the iron grinding waste recycling and reuse methods includes degreasing, heat treatment, sieving, matching, and obtains iron-based alloyed powders, which can be used in SHS lined steel pipe, powder metallurgy structural component, magnetic grinding, thermal spray. More than 95% iron-based alloyed powders can be recycled from wide source of iron-based grinding waste. The invention has the advantage of low cost, no secondary pollution and wide application.
