During the extraction of iron from haematite ore, limestone acts as a flux. Limestone decomposes froming CaO which reacts with silica forming slag. CaCO3 → CaO + CO2 CaO + SiO2 → CaSiO3 (slag)
Environmental Hazards of Limestone Mining The mine site conditions can affect the impact of dust generated during extraction, including rock properties, moisture, ambient air currents and prevailing winds, and the proximity to population centers. Fugitive dust can escape from trucks traveling on excavation haul roads and from blasting. This airborne dust can travel long distances from a
Extraction Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made. This study investigates the existence and quantity of stone at the site and also the economic viability of the process
Limestone is calcium carbonate ( Ca CO3 ) and it is added to the blast furnace to remove the impurities in the iron ore . Calcium carbonate is decomposed by heat in the furnace to give calcium
Answer:The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.

Dust is one of the most visible impacts associated with limestone quarrying due to the drilling, crushing and screening of the rock. The mine site conditions can affect the impact of dust generated during extraction, including rock properties, moisture, ambient air currents and prevailing winds, and the proximity to population centers.

The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide. \[ CaCO_3 \rightarrow CaO + CO_2 \tag{5}\] This is an endothermic reaction, absorbing heat from the furnace. It is therefore important not to add too much limestone because it would otherwise cool the furnace. Calcium oxide is a basic

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
