Minerals And Ores
Economic development continues to be dependent on the exploration of
natural Mineral Resources and their availability. The bulk of energy, fuel
requirement and raw materials come from the mineral wealth of the country,
which has enabled the industries to expand their activities, leading to the
economic development of the country.
However, there is a great need for ensuring the safety and quality of
materials being used. SRI assists the industries by providing accurate,
reliable and prompt testing services for evaluating minerals and Ores and
other building materials as per National and International norms.

Minerals Ores - An Overview
Civilization began when man learnt to put Minerals to use. The Earth's
Crust is made up of Minerals. The rocks ,in general ,contain two or three
minerals, although mono-Mineralic rocks e.g. Rock Salt, Marble etc. are not
rare. While minerals are generally composed of two or three elements, though
a few minerals e.g; Sulphur, Diamond ,Graphite etc. have only one element.
Minerals are the Inorganic substances having definite chemical composition
and certain characteristic properties. Though most of the minerals are of
Inorganic origin, some like Amber, Petroleum and Coal are of Organic origin.
These may not have fixed chemical composition or crystalline structure. Any
substance in which geological process is involved in their formation has
been grouped under mineral.
An ore is one that maybe used to obtain one or more Metals. Most of them
are metallic such as Galena, which is mined for Lead. A few are non-
metallic Ores such as Barite, Calcite, Kaolinite which are not mined for
minerals
