Abstract

With the excessive demand and continuous exploitation of traditional materials such as marble & granites for building material and phosphorites, nitrates and others for fertilizers it has become essential and inevitable to search for new alternatives and divert attention towards the utilization of unexplored and/or unexploited deposits along with the utilization of their co-products produced during mining in view of their extreme localization, exhaustibility and non-renewability. Finding the new modes of utilization of wastes not only enlarge the life of minerals but also help to foster the development of mineral resources (Rao and Reddy, 1985). Keeping this in mind, the present study was carried out. So, the recycling of solid waste produced by the processing of natural raw materials is very important in Indian context.

In the north eastern Indian Ocean there lies Andaman-Nicobar group of islands which are geologically very important and extend for more than 850 km. in the form of an arcuate chain. The Island Arc, which separates the Bay of Bengal from the Andaman Sea, lies in the form of two circular concentric arcs. The western sedimentary outer arc forms the major part of the Island while eastern inner arc is volcanic, exposed mainly in Narcondam and Barren Island which occur as conical volcanoes above sea level and south Andaman around Carbyn’s Cove, Birchaganj, Chidia Tapu near Portblair. A third arc to west of Andaman-Nicobar is in the process of emergence (Eremenco and Shastri, 1977). The exposed volcanic rocks are mainly basic to ultrabasic in nature.
