Because of its uniform texture and hardness, Granite is preferred for external use. It is more durable as compared to Marble and is economical in maintenance. Granite does not need re-polishing once it is polished and fixed at the desired place, while Marble needs polishing every year or at least once in two years. The granular formation and compactness of Granite makes it non-porous and non-absorbent hence more hygienic for the use in laboratories, kitchen, washrooms and other water exposed areas. Uniformity in texture gives better look to Granite and is thus convenient in its application at the desired place. Majority of the cities located closer to the sea, provide greater markets for Granite as it can withstand the weather effects (moisturizing) better than Marble. Usage of Granite in special work, mainly involved in the making and fabrication of sculptures, decoration items etc. is lower as compared to Marble. This is simply because Granite is a harder material to work on due to its compaction and silica contents. The distribution of granite use is illustrated in the figure below.

Granite is included in the list of largest minerals extracted among coal, chromites, rock salt, lime stone, china clay, dolomite, fire clay, gypsum, silica sand etc. Since 1990 mining & quarrying as consistently contributed 0.5 percent to the Gross Domestic Product. Production of Granite has grown substantially in the last twenty five years with total standing at about 5 million tons in 2003. It has been accompanied with high quarry wastage ranging from 61-73% in addit ion to poor quality, mainly due to unwieldy blasting techniques.
Processing industry is using wide array of technological options for basic as well as finishing stage, all of vintage age. Due to technological imbalance, wastages are around 52% to 55%. Presently the processing industry relies upon local manufacturers of machinery and equipment with a very few calibrated and high efficiency machines from reputable international suppliers.
The Granite Processing industry is closely related to the development of building materials, the modernization and vitalization of which leads to the progress of the tile industry. It shows a trend towards increasing use in modern architecture.
