The leaching kinetics of iron during the atmospheric direct leaching (ADL) of marmatite concentrate was studied under the following conditions: reaction temperature of 343–383 K, slurry pressure of 0.3–0.7 MPa, and particle sizes of (−74 μm, +63 μm), (−63 μm, +44 μm), and (100% −44 μm). The statistical effects of reaction temperature, total pressure, and particle size of concentrate on the extraction and leaching rate of iron were analyzed. The results show that reaction temperature is a significant factor, while slurry pressure and particle size are not statistically meaningful with respect to either the extraction or the leaching rate. The extraction of iron fits better to the mixed-controlled shrinking core model, and the apparent activation energy was calculated to be 37.66 kJ/mol. The leaching of iron is therefore mixed-controlled by the interfacial chemical reaction and diffusion across the product layer.
