Method for producing low nickel matte through vulcanization of calcined sand

The invention discloses a method for producing low nickel matte through the vulcanization of calcined sand. The method comprises the following steps of: (1) mixing and calcining a lateritic nickel ore, a reducing agent and a first slag forming agent to obtain the calcined sand; (2) vulcanizing the calcined sand to obtain sulfur-containing calcined sand; (3) smelting the sulfur-containing calcined sand in an electric furnace to obtain the low nickel matte and waste residues. According to the method for producing the low nickel matte through the vulcanization of the calcined sand of the embodiment, the calcined sand is obtained through calcination and then is vulcanized and smelted in the electric furnace so that the nickel matte product is obtained. The method is strong in operability and can be used for carrying out smelting operation on the lateritic ore in regions lacking of electric power; coals can be used as energy sources of the whole production process; and in the production process, a waste heat power generation technology can be used for recycling heat energy after high temperature flue gases are dedusted, thereby achieving the effect of effectively reducing the energy consumption in the whole smelting process.
