Seminar On :

Limestone is a Sedimentary rock Composed

Primarily of Calcium Carbonate (CaCO3) in the form of the Mineral calcite. It most Commonly forms in clear, warm, Shallow marine waters.

It is an Organic Sedimentary rock that forms from the Accumulation of shell, coral, algal and fecal debris. It can also be a Chemical Sedimentary rock formed by the Precipitation of Calcium Carbonate from lake or ocean water.

What Is Limestone?

Limestone often Contains Variable Amounts of

silica in the form of Chert or Siliceous Skeletal Fragment, and Varying Amounts of clay, silt and sand Carried in by Rivers.

Some Lime stones do not Consist of grains at all, and are Formed Completely by the Chemical Precipitation of calcite or Aragonite, i.e. Travertine.

Secondary calcite may be Deposited by Supersaturated Ground waters (Groundwater that Precipitates the Material in caves).

CONTENT OF LIMESTONE

1) Cement Industry 2) Iron & Steel Industry 3) Chemical Industry 4) Sugar Industry 5) Glass Industry 6) Fertilizers Industry

REQUIRMENT OF LIMESTONE IN VARIOUS

INDUSTRIES

Gujarat state is richly with the various types of limestone

deposits ranging in age from Precambrian age to Pliocene age.

GSI and CGM (Govt. of Gujarat) have Investigated and Assessed the limestone Deposits in the State and large reserves of the limestone have been Indicated by detail work Including Investigation by Drilling Techniques and a total of 90,37,337 Million Tonnes of limestone have been Assessed as Recoverable reserves. Proved category of limestone Reserves 3,71,512, Probable category 1,10,583 and Possible category 73,59,987 Million tonnes of limestone reserves have been Estimated.

District Wise Capacity of Limestone Deposits

Nummulitic Limestone Deposits Of the Western Kutch

Map of Limestone Deposits of the Kutch District

There are Mainly Two Methods are Involved : 1) Conventional miningThe main activities involved in the Conventional Mining of the Limestone Deposits are:1. Ground preparation2. Drilling3. Blasting4. Loading, Transport and unloading5. Crushing6.Transportation through Belt conveyor.

Mining of Limestone

2) Surface mining :~ Surface miner performs in site crushing while mining, which cases out the problems encountered in transportation of limestone to crusher. The system needs no separate loading arrangement and the machine loads the material directly to the trucks or dumpers. ~ The need for haul road maintenance is drastically reduced, since the mine surface with the surface miner is very gradual and uniform.
