Laterite Soil - an overview | ScienceDirect Topics

10.1.3.9.3 Laterite soils. These soils are found in the areas with heavy rainfall, particularly near coasts of India. It is the acidic soil and is rich in iron; hence, the soil provides red appearance. This soil is utilized for growing more tropical crops, like rubber, cashew, coffee, coconut, and tea.

Processing of Nickel Laterite Ores on the Rise

The SX-EW Method. SX-EW, or the Solvent Extraction – Electrowinning approach to lateritic ore beneficiation, is a hydrometallurgical method that relies on leaching, extractants, and electrowinning to produce nickel from ore. This process is often referred to as Leach Solvent Extraction – Electrowinning for its employment of a leaching step.

Mineralogical Characteristics of the Nickel Laterite, …

With the sharp decrease of sulfide nickel resources, the nickel laterite is becoming more attractive as nickel oxide, nickel matte, and nickel-iron. This study investigated the mineral phase structure, chemical analysis, thermal properties, and element distribution characteristics of the rotten rock layer deposited in the Southeast Sulawesi Ophiolite Belt. The results show that …

Mineralogy and geochemistry of the Berong Ni-Co laterite …

The laterite profiles investigated in the present study developed after the emplacement of a slab of oceanic crust and upper mantle sequence (the Semail ophiolite) onto the East Arabian margin during the Late Cretaceous. The laterites formed as a result of prolonged weathering of the ophiolitic assemblage under tropical to subtropical conditions.
