Limonite: The mineral Limonite information and pictures
Limonite commonly forms as a pseudomorph over other minerals, especially Pyrite, Marcasite and Siderite. These pseudomorphs are very identifiable by their partial rusting look and yellow staining. Chemical Formula. FeO (OH) · nH2O. Composition. Hydrous basic iron oxide, with an indefinite composition. Color. Yellow, brown, reddish-brown.

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.
