Production of Ferroalloys and Recycling in the Continuous Oxygen Reactor


A new technology for the production of ferronickel in a new type of unit – a continuous oxygen reactor (COR). The heat source of the process is heat from the afterburning of the exhaust gases. High recovery rate is achieved by carrying out the recovery process in the ore-coal briquettes. Briquettes are located on a carbon substrate. The products are metal and slag granules. The process is characterized by satisfactory performance and low cost of ferronickel.
