Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

Abstract. Limestone deposits are primary raw material for cement manufacturing plants. An ore grade model is generated based on estimation methods to control quality of the raw materials. However ...

Limestone occurs as regular beds in sedimentary sequences. In metamorphosed terrain they tend to occur as thin narrow bands and show complex structures. Depending on size, shape and deposition, three types of limestone deposits are recognised - …

These emissions are primarily associated with (1) the burning of fossil fuels to heat cement kilns and (2) the release of CO 2 during limestone calcination. One proposed strategy for CO 2 reduction includes the use of functional limestone fillers, which reduce the amount of portland cement in concrete without compromising strength.

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.

The ownership of Obu mines has been a subject of dispute between the Africa's leading Cement manufacturers, Dangote Cement Plc and Bua Cement, which the Federal Ministry of Mines had asked to vacate the mines because they were exploiting limestones in the area illegally. The Federal Government lamented that the country lost about $9billion in ...

The extra siliceous limestone sample of the Lower Eocene from the abandoned cement quarry part of the limestone deposit from the area of Bizerte (Extreme North East of Tunisia) has been investigated for its suitability for cement making. Petrological as well as X-ray diffraction pattern studies indicated that the limestone …

India: Shree Cement has offered the highest bid in an auction for limestone deposits at Karhi Chandi, Baloda Bazar in Chhattisgarh. The site has estimated reserves of 155Mt of limestone in …

Sri Lankan limestone deposits are well spread from Puttalam, Jaffna to Mullaitivu cities over the coastal belt. This limestone region is commonly named as Jaffna limestone region.

Some limestone mines contain reserves that are massive, thick deposits with small variances in the chemistry of the limestone. Provided there are no complicated geologic structures within the deposit, the mine can rely heavily on the original core testing data to predict the quality of the limestone feeding the plant. Core holes can be widely spaced …

Cement firms jostle for Kenya's Kitui's limestone. The vast mineral resources in Kitui County have seen several firms work overtime to elbow out their rivals in a bid to stake a claim to the ...

Crushed limestone is often the main raw ingredient in the manufacture of portland cement clinker that eventually becomes cement. Other raw material sources of calcium carbonate include shells, chalk or marl, which are combined with shale, clay, slate, blast furnace slag, silica sand or iron ore.

He briefed that NCCBM in association with IBM has been compiling National Inventory for cement grade limestone. Based on the exploration data generated at present, total available limestone reserves are 124 billion ton-nes which appears to be huge. Further, out of these total limestone reserves, only 26 % i.e. 32 billion tonnes are under …

Prior to the design and planning of a mine and during its early stage of operation, one crucial step to take in order to ensure proper design, planning and optimum productivity is the determination of the deposit's geotechnical parameters. The study was therefore conducted to investigate some key geotechnical properties of Ibese Mines limestone …
