Limestone - Sedimentary rocks

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly

High-Calcium and Dolomitic Limestone Graymont

High-calcium Limestone Graymont mines some of the best limestone deposits available. As a result, we can produce a chemical-grade limestone that satisfies a wide range of industrial and agricultural specifications. Applications of this product include the supply of high-calcium sized stone as a lime kiln feedstock, in order to meet the specific raw-material needs of the various PCC markets and ...

Optimizing the Choice of Limestone Deposits for the ...

2018-10-9  Despite the presence of raw materials (limestone and clay) deposits for Portland cement production, the major part of cement sold in Cameroon is from crushed imported clinker. This contributes to high cost of this material and reduction of local employment. In this study and based on existing data, a multi-criteria analysis tool was developed and applied to guide decision in the choice of ...
