Latest Patents

One of Kim's latest patents is a method for crushing hard tungsten carbide scraps. This method involves mixing tungsten carbide scraps, which are often discarded metalworking tools, with aluminum and heating the mixture to high temperatures. This process forms intermetallic compounds and metal oxides, which can then be crushed for further processing. Additionally, Kim has developed a method for recovering tungsten and cobalt from tungsten carbide scrap powder through alkaline and acid leaching methods.

Another significant patent addresses the separation and recovery of iron from waste non-ferrous slag generated during the smelting of metals like copper, zinc, and lead. This method utilizes a reducing agent and a reaction catalyst to convert amorphous iron oxides into crystalline iron and iron carbide. The resulting material is then crushed and separated using magnetic techniques to recover iron concentrates.
