  • Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarsely crystalline, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy. Outcrops of granite tend to form tors, and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels.
  • Granite is nearly always massive, hard and tough, and it is for this reason it has gained widespread use as a construction stone. The average density of granite is 2.75 g·cm-3 with a range of 1.74 g·cm-3 to 2.80 g·cm-3. The word granite comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a crystalline rock.
  • There are, four operations that are involved in the processing of granite. They are: Dressing,Cutting/Sawing,Surface Grinding and Polishing and Edge-Cutting-Trimming. Mining for granite is done manually. For drilling and channeling hand chisels and hammers are used. There are very few quarries that have mining machinery, such as compressors and drilling machines for drilling and blasting, cranes for lifting big blocks, and dampers and trucks for transport.
  • Granite has been extensively used as a dimension stone and as flooring tiles in public and commercial buildings and monuments. With increasing amounts of acid rain in parts of the world, granite has begun to supplant marble as a monument material, since it is much more durable. Polished granite is also a popular choice for kitchen countertops due to its high durability and aesthetic qualities. Currently 33% of the kitchen countertops being made are of granite.
  • The granite industries involved in cutting, polishing and finishing have some common problems. Most problematic of them are related to stains on the finished products arising out of various factors such as contamination, use of steel pellets, treatments for the machinery, water quality, the quality of granite itself, the environmental factors and many others related to them. The stains on the finished products have a profound effect on production cost and as a whole on the financial side as the stained products cannot be marketed or has to be disposed of at a lower price. Sometimes the pile up of such non-marketable stained products becomes a problem to the company. The company sometimes incur heavy losses due to the same.
  • Conventional methods of quarrying granite are becoming increasingly expensive in real and environmental terms. The existing flame torch is, for example, a slow, destructive and noisy method of creating slots. In order to overcome the problems of current equipment, a high pressure water jet slotting device has been developed, field evaluated and is now in commercial production. Water jet cutting has also advantage in secondary preparation of monument stone, where the jets can create straight surfaces and right angled cuts to an adequate level for final surface acceptance.
  • Accruent, Inc., the leading provider of contract management solutions, announced today that it closed $12 million in a new round of funding. Accruent has now raised more than $35 million in capital since the company's inception in 1995.
  • Finland is one of the major exporters of granite and a world-leader in soapstone production. The annual turnover of the industry is approx. 200 million Euro, divided equally between soapstone and granite products. The value of export is approx. 40% of the turnover. Approx. 200 actively operating companies are found in the line of natural stone business in Finland, employing approx. 2000 persons (with spin-off approx. 3000 persons).
  • Granites are now mined in most of the Indian states for use as construction material and road metal but production of dressed granite blocks and slabs from Andhra Pradesh, Karnataka, Rajasthan and Tamil Nadu are highly priced. In India there are 43 granite processing units of which 12 are in Andhra Pradesh, 13 in Karnataka, 3 in Rajasthan, 14 in Tamil Nadu and 1 in Orissa.
  • The recovery of marketable grade granite is reported to be 32 to 40 per cent in Karnataka, 25 to 75 per cent in four quarries around Jalore, the main granite mining centre of Rajasthan, and 20 to 40 per cent in Tamil Nadu. Granite exports from India last fiscal were worth Rs 3,018 crore. While Andhra Pradesh accounted for 35 per cent of exports, Tamil Nadu’ share was 33 per cent and Karnataka’s 32 per cent.
  • Indian granite industry has been demanding the government to implement the GCDR 1999 in all States which would make available the required quantum of raw material to the industry, by liberalising the quarry leasing policy.
  • Chinese companies have the advantage of a liberal policy and are able to lead the market. The government there gives several incentives
  • India leads in the production of natural Stones with 35342 million tonnes followed by Chinawith only 31000 tonnes
  • India could export more but China seem to have definite advantage
  • China imports natural stones from several countries, including India, and re-exports them in the International Market @ prices which the India Stone Industry cannot compete with .
  • China imports natural stones from several countries, including India, and re-exports them in the International Market @ prices which the India Stone Industry cannot compete with .
  • In India, at present import of Granite is not allowed ; Chinese companies import natural stones from around the world and re-export after value addition
  • China exported 16 million tonnes of stone valued at $ 3.04 Billions in 2010 while India could export only $ 600millions
