A method of using nickeliferous laterite to reduce ferronickel directly in tunnel kiln relates to a method of reducing ferronickel. Comparing with high furnace smelting ferronickel and electric furnace smelting ferronickel having problems such as great invest, high manufacturing cost and produced ferronickel with high carbon content, the method of the invention is finished as: selecting nickeliferous laterite as material, the nickeliferous laterite contains 0.75-2.60% by weight of nickel, 8.00-55.0% by weght of iron; adding weight ratio of nickeliferous laterite and reductant as 1.00:0.25-0.55 into reducing pot, then putting the reducing pot in tunnel kiln, through preheating and stoving, heating reducing, cooling, taking off to get qualified reduced directly nickeliferous laterite. The invention selects natural nickeliferous laterite as material to reduce nickeliferous laterite, having advantages such as technology which easy to control, simple operation, low dissipation of energy, environment protection without pollution, low manufacturing cost, low installion cost and produced ferronickel with low carbon content.
