摘要:The prent invention provides a method for recycling waste cemented carbide by molten salt chemistry, comprising the steps of: () carrying out vacuum dehydration on a molten salt media; () carrying out oxidation-dissolution reaction on waste cemented carbide in the molten salt media; () carrying out deoxidation treatment on a molten salt system; () carrying out thermal reduction reaction on the molten salt system; and () washing filtering and vacuum drying obtained mixture by thermal reduction reaction to carry out paration and collection of the molten salt media and waste cemented carbide nano powder. Compared with existing method for recycling waste cemented carbide, the invention has the advantages of short flow, simple equipment, low energy consumption, and excellent recycled products. Moreover, the invention doesn't produce
solid/gas/liquid harmful substances to pollute the environment, and can create enormous economic and social benefits.
