Shing Laterite Iron Ore. Lateritic nickel ore deposits . Lateritic nickel ore deposits are surficial, . 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low grade iron ore.
Upgrading low nickel content laterite ores using Since traditional beneficiation processes are impractical, it would seem attractive to introduce a pre treatment process to reduce the nickel oxide in the laterite ore to metallic nickel, whilst controlling the iron oxide reduction and then separate the valuable product from the large quantities of iron bearing gangue using magnetic separation.
(1) A thermodynamic model was developed to describe the carbothermic reduction roasting process of a limonitic laterite ore using HSC Chemistry 7.1 and was utilized to predict the grade of the ferronickel alloy and the nickel recovery to the ferronickel alloy.
Nickel is sourced from sulphide and laterite ores. While 70% of the nickel resources are contained in laterites, these ores are often complex and expensive to treat using conventional methods.
Lateritic weathering of metamorphosed Proterozoic banded iron formation (BIF), locally named itabirite in Brazil, produced large deposits of iron ore.
The method(s) chosen is dependent on the composition of the unique ore source. Most laterite ore deposits are made up of both limonite (iron rich) and saprolite layers, with the thickness of each layer varying significantly across different deposits.
Iron ore deposits are mostly covered by laterite. The laterite at places appears to be very hard and compact. At some places, the laterite is having hard lumpy ore pieces. The chemical composition of the laterite ranges from 20 to 38% Fe and alumina ranging from 2 to 30%. Ferruginous/Phyllitic clay is exposed at very small place.
