Limestone is a sedimentary rock composed primarily of calcium carbonate with the occasional presence of magnesium. Most limestone is biochemical in origin meaning the calcium carbonate in the stone originated from shelled oceanic creatures. Limestone can also be chemical in origin as is the case with travertine.
In the current research, isothermal experiments of kinetic analysis were performed at different temperatures (800–1050 °C) and particle sizes (885 to 10,763 μm) to investigate the calcination kinetics of high-purity limestone. Thermal analyses were carried out in a zirconia crucible, 1 cm in height, for different temperatures and particle sizes. The …
An analysis is made of the tools and methods for quarrying limestone and sandstone in ancient Egypt. It is concluded that the chisel, originally of copper and later of bronze or iron, was the principal quarrying tool during all periods, with chisels becoming longer (over 50 cm) at the beginning of the New Kingdom (about 1500 BC).
Limestone Mining Methods. Today, as in the past, the most demanding task of limestone mining was the cutting and lifting of the blocks of stone out of the ground, then hauling them to the mill. As has been said, it was not just the high quality of the limestone that developed the industry here, but the rock was close to the surface. ...

Egyptian limestone is used for both outdoor and indoor applications. In flooring one needs to be careful in high traffic areas in the sense that more treatment of the surface is needed. With Egyptian limestone it is easy to make staircases 3m in length of one piece, something that can be more difficult with some other limestones. .
Environmental Impact Assessment (EIA) is a prominent technology to assess the environmental changes in the open cast Limestone mining region. However, traditional EIA methods and Limestone deposit identification involves time consuming, cost effective and manpower requirements. We cope-up these problem and incorporated with different …
Spectral remote sensing mapping methods were applied for mapping apatite mineral as a key indicator of phosphate ore outcrops at the eastern side of Abu Tartur Plateau, Western Desert, Egypt, using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Landsat series imagery. Previous investigations of …
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long …
