As for what makes money in the 21st century, waste collection has become a popular "industry".

       In recent years, waste recycling professionals have summed up the experience that in cemented carbide recycling practice, due to increasingly strict environmental protection requirements, some of the recovery process will bring pollution due to discontinuation of use. Currently widely used in mechanical pulverization, zinc melting appliances and electrochemical selective dissolution. The hard phase tungsten carbide cobalt binder phase forms the microstructure under powder metallurgy sintering at a certain temperature.

How dense and cemented carbide can be decomposed, the first step in rebonding the hard phase and separation during metal recovery is a critical step to address. For the dissolution of carbides, many researchers have adopted different recycling process routes and different ideas. For the evaluation of these processes, it is difficult to choose more reasonable and more economical, and should be widely used, because the first basic principle of the selection of the process route is to use high-quality recycled products, the process is simple, and the environment will not produce two less polluted, clean and safe working conditions.

      Now a brief introduction to several common recycling processes. Custom carbide recycling has been a concern of the industry since its inception. Since calcium carbide is the main raw material, tungsten carbide and cobalt metals whose economic value and production cost are relatively high, the recovery of cobalt and tungsten is a very valuable collection field.
