High Temperature Pressure Oxidation of a Low-Grade Nickel ...

High temperature pressure oxidation of a low-grade nickel concentrate was examined to demonstrate the potential benefits and shortcomings of this approach. The high iron sulfide content ensured that acid generation was much greater than for higher grade concentrates. This results in the formation of basic iron sulfate phases and a significant amount of sulfuric acid.

Iron | Minerals Education Coalition

Iron is the third most common element making up the Earth. Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite (70% iron) and magnetite (72% iron). Taconite is a low-grade iron ore, containing up to 30% magnetite and hematite.

Column Leaching of Greek Low-Grade Limonitic Laterites

In this study, column leaching experiments were carried out to investigate the extraction of Ni and Co from low-grade limonitic laterites from Agios Ioannis mines in central Greece. Tests were carried out in laboratory Plexiglas columns using H2SO4 as leaching solution. Parameters determining the efficiency of the process, i.e., acid concentration (0.5 M or 1.5 M) and addition of 20 or 30 g/L ...

Leaching of Low Grade Nickel Sulphide ... - AusIMM

A low-grade disseminated nickel sulphide serpentinite ore from W.A. had a relatively high permeability after drying. Various techniques indicated that the permeability resided within a fine network of fibrous vein- lets and especially within coarse cracks along which the sulphides lay. The ore minerals were therefore open to selective extraction by chemical leaching.

The deposit of nickel ore in Indonesia is very abundant. High grade ore has been processed to produce ferronickel, but low grade nickel ore is still left as by product without being processed. This kind of ore has been attempted to be processed through atmospheric leaching and carbon reduction, separately. In atmospheric leaching process, it is found that iron and nickel can be separated from ...
