Study of selective reduction in lateritic nickel ore ...

+

The difference between magnesium and silicon oxide in lateritic nickel ore plays an important role in the selective reduction process. Therefore, in this work, the selective reduction of saprolite and limonite was carried out to reveal the effect of lateritic nickel ore basicity (MgO/SiO2ratio) on phase transformation and microstructure of reduced nickel ore. The raw materials, such as nickel ...

lateritic ore. METHODS Low grade nickel layer of lateritic ore was obtained from a mining site in South East Sulawesi, Indonesia. This low grade layer was ground and milled to obtain a 200 mesh (74 micron) particles. The milled layer was mixed with coal in weight ratio of coal to ore at 8:2 prior being pelletized. The pellet was put in muffle furnace to be heated at temperature range of 800 ...

The nickel lateritic ore is normally the overburden (in the present case, it is the overburden of chromite mines), which is nothing but the soil and dust removed in order to access an ore or mineral body. The huge amount of overburden (nearly 8 to 10 times that of the ore) that is generated during chromite mining and dumped nearby has found a very little use so far. With the continuous ...

Laterite ore is one of the important sources of nickel (Ni). However, it is difficult to liberate Ni from ore structure during reduction roasting. This paper provided an effective way for a robust recovery of Ni from laterite ore by H2 reduction using sodium thiosulfate (Na2S2O3) as a promoter. . It was found that a Ni content of % and a Ni recovery of % were achieved with 20 wt ...

 · Most nickel laterite deposits were first found during the nickel boom but not considered at that time to be economically significant. A large surge in exploration activity, much of it focused on resource delineation rather than true greenfields exploration, occurred between 1996 and 2001, triggered by the advent of the Pressure Acid Leach (PAL) technology in the mid1990s.
