Technology of using exhausted copper-magnesium catalyst and copper-containing waste of circuit boards etching

Application: the technology is designed to prepare copper-containing waste and their further use for low-alloying gray cast iron with the aim of improving its brand.

Advantages: the use of secondary resources, safety and ecological purity of the process.

Key features: technology allows using for alloying of cast iron waste without prior processing, which reduces the cost of products compared with the use of pre-made alloying alloys.

Developed: Research and Innovating Laboratory of New Constructional Materials, Prof. Dr. Oleg Komarov, D.Sc. (Doctor of Techn. Sci.).
