Recently, Zhejiang Huayou Cobalt Industry Co., Ltd. has obtained a patent named "A method of producing high ice nickel and ferric iron from ferronickel", with the authorisation number CN116162804B and the application date of February 2023, which marks an important breakthrough in technological innovation and industrial upgrading in the field of ferronickel production. The acquisition of this new patent marks an important breakthrough in the technological innovation and industrial upgrading of the company in the field of ferronickel production.

The patent discloses a method of producing high freezing nickel and iron in ferronickel, which adopts the process of "Oxygen-rich continuous blowing + P-S converter deep blowing + hot slag iron extraction". In this process, low ice nickel and/or ferronickel are used as raw materials, and are continuously blown in a continuous blowing furnace with oxygen enrichment to produce medium ice nickel and continuous blowing slag. Then the medium ice nickel is transported to the P-S converter for deep blowing to get high ice nickel, and the continuous blowing slag is settled and then reduced to extract iron to get iron.
