Ilmenite also known as manaccanite is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide which is used in paints printing inks fabrics plastics paper sunscreen food and cosmetics.
Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining in which the overlying rock is left behind and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface .
The underground mining methods we use include room and pillar narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them

Laterite is both a soil and a rock type rich in iron and aluminum 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 .

There are four main mining methods underground open surface pit placer and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels beach sands or other environments.
