Laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content.
They develop by intensive and prolonged weathering of the underlying parent aureusid.comal weathering (laterization) is a prolonged process of chemical weathering which produces.
tification of laterites is the large area of the tropical and subtropical zones involved and the different degrees of laterization encountered in the various parts.
Martm and Doyne Laterites book used the silica-alumina ratio as a classification criterion: Soil Type Laterite soil Lateritic soil Non-lateritic soil Si02/Al 1.
Limonitic laterites are usually leached by concentrated sulfuric acid at °C and kPa in acid-resisting brick-lined autoclaves. Nickel and cobalt sulfides are then precipitated from solution by H 2 S and sent for further processing.
Serpentinic laterites contain appreciable amounts of. This book analyses and discusses the laterites in the Bengal Basin. It uses field-based studies, quantitative analysis and thematic mapping to cover areas of palaeogeography and regolith geology in connection with laterite genesis, palaeoweathering, tectonic geomorphology, and more.
The purpose of this book is to describe how these metals are produced from the ores that are mined. Nickel is mined from two types of ores, laterites and sulfides which are given in a detailed flow chart.
Laterites book are found mostly in tropical regions and sulfides are mostly found in Canada and North Siberia. Note: Citations are based on reference standards.

Feb 28, · Laterites, products of tropical weathering, cover about one third of the world land surfaces. Inventories and interpretations concerning the worldwide distribution of laterites have considerably.
Laterites consist mainly of quartz, zircon, and oxides of titanium, iron, tin, aluminium and manganese, which remain during the course of weathering. Quartz is the most abundant relic mineral from the parent rock. Laterites vary significantly according to their location, climate and depth.
Laterites are regoliths developed under tropical to subtropical conditions and are host to key deposit types, notably bauxites (major sources of Al, derived from weathering of aluminosilicate rocks) and Ni-Co laterites (derived from ultramafic rocks). Related Book Content.

Nickel oxides (laterites) were first processed by hydrometallurgy in at Nicaro in Cuba (by the Caron Process) and in the first sulphuric acid pressure leach plant came on line at Moa Bay, Cuba; thereby adding nickel laterites as a significant source of by-product cobalt – a source that would grow in importance subsequently.
Dec 08, · LATERITE STORY Of the various soil types that occur in the tropics and sub-tropics, laterites are of special interest in conjunction with building construction. These are highly weathered soils, which contain large, though extremely variable, proportions of iron and aluminium oxides, as well as quartz and other minerals.
It's a shame that the highly depressed nickel market led to the cancellation of MEI's October Nickel and Cobalt Processing conference, as there are enormous challenges in the processing of nickel ores, particularly the laterites.
The majority of the world's nickel resources occur as laterite ores, which are complex, low grade, and expensive to treat using conventional smelting and high. This book presents a collection of authoritative papers covering the latest advances in all aspects of nickel and cobalt processing, including fundamentals, technology, operating practices, and related areas of Platinum-Group Metals (PGM) processing.
Laterites are very uncommon in North America. Because laterites are formed in tropical climates any laterites in North America are exhumed ancient soils from a time when the soils were in a tropical latitude. Aluminum laterites, such as bauxite, found in Arkansas and some other southeastern states, and the Carribean are the source of aluminum foil.
