Reducibility of nickeliferous limonitic laterite ore from

Limonitic nickel laterite from Sivrihisar reserve in Turkey was reduced at 7001100°C 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.

Selective Leaching Nickel from the Pre-Reduced Limonitic

In this paper a novel method for selective leaching nickel from pre-reduced laterite ore at atmospheric pressure was reported. The reduced calcine was leached in thin acid liquor to liberate the nickel and iron together firstly. By properly controlling the leaching condition, the leached iron ion could hydrolyze as goethite precipitate and regenerate the acid consumed in the leaching procedure.
