CHEMICAL HEAT TREATMENT OF DUMPED NICKEL SLAGS TO RECOVER NICKEL AND IRON

Abstract

Here is estimated the feasibility and efficacy of the application of the method of chemical-thermal treatment of dumped nickel slags chlorides with nickel deposition reagents on iron substrate in the charge. Magnetic separation of treated slags retrieves metal education after in concentrate smelting which allows get ferronickel. Not magnetic concentrate and slag from the furnaces of the magnetic concentrate can be used in the cement industry and in construction as rubble or filler concrete.
