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 rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which produces

It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content. Goethite and turgite come between hematite and limonite in composition, and are found with both, but are comparatively rare. Iron ores cannot be profitably mined unless they occur in large bodies.
India’s exports of ores and minerals went up by 42% between 2001-02 and 2003-04; an increase mainly due to the rise in exports of cut diamonds and (76% of value of total minerals exported) and iron ore (10.5% of the value), the key minerals exported from India.
Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical, and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium.
necessary to categorize the ore samples. On the basis of their chemical composition and chemical properties, the categorization makes the opening of an ore easy and logical. Following are the main categories of ores on the basis of their chemical composition. 1. Carbonates 2. Sulphides and Pyrites 3. Oxides 4. Sulphates 5. Silicates
