1. Fluxing Agent: Limestone is commonly used as a fluxing agent in the iron and steel industry. It is added to the blast furnace during the production process to remove impurities and facilitate the formation of slag. The slag helps in the removal of impurities like sulfur and phosphorus from the molten iron [ 3 ]. 2.

In limestone mining, the waste deposit ratio is too high. To minimize waste extraction activities, hyperspectral remote sensing imagery utilized to identify the purest form of calcite in the examination area. This report reviewed papers on the possible impacts of the mining region's limestone quarrying activities on the atmosphere and climate ...

The effects of temperature and particle size on the calcination process were assessed by calcination experiments, and the calcination kinetics and the activation energy were obtained. In addition, the produced quicklime was characterized. 3.1 Characterization of the Sample. The obtained limestone had relatively high purity.

Mining is the extraction of economically v aluable minerals or other geological materials from the e arth. surface. It may be from an ore body, lode, vein, seam, reef or placer deposits. Since the ...

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 …

The rock failure process is associated with acoustic emission (AE). Hence, violent rock failure processes such as rock burst under different stress paths in laboratory can be studied using the AE monitoring technique.In this paper, single-face dynamic unloading tests under true-triaxial condition were carried out for Paleozonic marine …

Limestone is a basic type of ore which is abundant in the world. It is primarily used to produce Concrete, an essential material in factory construction.
