Laterite Ore an overview ScienceDirect Topics

Laterite Ore. Laterite ores are formed by the process of weathering and normally found in tropical regions where weathering extracts and deposits it in layers at varying depths below the ground surface. From: The Utilization of Slag in Civil Infrastructure Construction, 2016. Related terms: Iron Oxide; Titanium Dioxide; Ilmenite; Smelting; Leaching

THE KINETIC PROFILE OF IRON DISSOLUTION FROM

to process the laterite ore is the low temperature route of process. Such a process is quite simple, in which the laterite ore is dissolved in acid solution prior to the refining stage. Iron dissolution is a very important step; it determines the recovery of iron for the whole process (Solihin, Mubarok, et al. 2015).

Metallurgical Beneficiation of Iron Laterite Ores with

A new process is developed for metallurgical beneficiation of iron laterite nickel-containing (limonite) ores with the formation of a metallic nickel–cobalt concentrate. This process includes reducing roasting of the ores with sulfur-containing additions in the temperature range 1100–1200°C, the fragmentation of the roasting product, and the magnetic separation of metallic and slag phases.

Development of the iron-focused laterite (ARFe) process

The autoclave conditions facilitate rejection of the iron as an oxide-based residue (i.e., Fe 2 O 3 [haematite] or H 3 OFe 3 (SO 4) 2 (OH) 6 [jarosite]) while regenerating the acid consumed during leaching of iron minerals from the ore.In view of the dominant quantity of iron in typical limonite ores (i.e. 40 -50% Fe), it has long been desired to develop a commercial-scale process that is capable of

Extraction of Nickel, Cobalt and Iron from Laterite

Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte. High iron (> 35 % Fe) limonitic ores can be treated by high pressure leach using sulfuric acid.

Direct extraction of nickel and iron from laterite ores

2013-12-1  1. Introduction. Over the past 30 years laterite ores have become increasingly more important as a source of nickel metal (Dalvi et al., 2004).Several methods of nickel extraction from laterite ores have been piloted and some were put into full operation, including acid leach with sulphuric, nitric and hydrochloric acids, ammonia leach and the pyrometallurgical process (Superiadi, 2007).

Processing of Nickel Laterite Ores on the Rise

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. Limonite, which accounts for nearly double the amount of saprolite available globally, is more amenable to processing via hydometallurgical techniques, while saprolites are
