Method for processing laterite nickel ore with direct production of ferronickel |
| abstract |
The invention relates to the field of non-ferrous metallurgy and specifically to a method for processing laterite (oxidized nickel) ores with the direct production of ferronickel in the form of metal granules. The method comprises mixing the ore with a solid reducing agent and with fluxing additives, briquetting the resultant mixture, a reduction firing of the briquetted charge in tubular rotary furnaces forming ferronickel lumps and separating ferronickel from ground clinker. The fluxing additives are input into the mixture in the amounts of 6-12% CaCO3, 6-12% Al2O3, 0-10% SiO2 of the mass of the ore, the maximum temperature in the lump formation zone is maintained in the range of 1300-1350ºC, and the content of carbon residue in the clinker slag is maintained in the range of 0.05-0.55%, and preferably within the range of 0.1-0.4%. A mixture of bituminous coal and anthracite or coke is used as the solid reducing agent. The method allows for achieving high performance when firing in order to increase the effectiveness of directly producing ferronickel from high-magnesium silicate nickel ores. |
