Influence of laterite nickel ore on extracting iron from ...

2021-3-19  In view of the difficulty of extracting iron from Bayer red mud, a new idea of adding laterite nickel ore into red mud was proposed to prepare a high value-added product. Toward this, the influences of laterite nickel ore on thermodynamic reaction, slagging and smelting reduction of extracting iron from red mud were studied. The results indicated that the product of extracting iron from red ...

Ochreous laterite: a nickel ore from Punta Gorda,

2001-7-1  Nickel laterite profiles generally comprise a saprolitic zone in which Ni is combined with silica (garnieritic ore) overlain by a leached zone in which Ni is associated with iron oxyhydroxides (oxidised ore). The oxidised ore is especially abundant in the Cuban lateritic nickel deposits (De Vletter, 1955, Lelong et al., 1976).

Nickel-Bearing Laterite Deposits in Accretionary

2019-6-24  Nickel production is vital to modern economic development. Of the different ore types, supergene Ni-laterite production, as open-cast mining exploitation, is on the rise and surpassing the more conventional hypogene sulfide type. This trend will likely continue. Assessing the global resource of Ni laterite is therefore of crucial importance.

The reason for the 1.7% nickel extraction increase from 80 oC to 90 C was attributed to the increase in the iron extraction since nickel and iron minerals were associated in the same minerals. Since the nickel extraction increased marginally at 80 0C, compared with iron extraction, 80 oC was seen to be an optimum.
