Limonitic nickel laterite from Sivrihisar reserve in Turkey was reduced at 700-1100uC by the addition of 5?74, 8?61 and 11?48 wt-% coal under an argon atmosphere. The run-of-mine ore and the reduced samples were studied using X-ray diffraction. The metallisation of Fe was found to be limited up to 900uC, but increased rapidly at higher temperatures. The metallisation of Ni and Co increased when the temperature was increased from 700 to 800uC, almost levelled off up to 900uC and then increased up to 1100uC. The results also showed that increased coal additions did not affect Fe metallisation up to 900uC. At 1000uC the metallisation of Fe became slightly better, but its effect was more pronounced at 1100uC. The increased coal addition affected the nickel reduction equally at all temperatures, while it had no effect on the metallisation of Co.
