Why did the white limestone come by water?
Limestone can and does appear in shades of green, due to impurities.
What is the purpose of limestone in the blast furnace?
Limestone is added to the blast furnace as a flux material. It helps to remove impurities in the iron ore by forming a molten slag that floats on top of the molten iron. This slag can then be easily separated from the iron.
What does a limestone smell like?
Limestone is primarily composed of calcium carbonate, which is a mineral with no inherent odor. However, limestone can sometimes have a faint earthy smell due to the presence of organic matter or impurities in the rock. Overall, limestone itself does not have a distinct smell.
How does calcium carbonate purify iron?
Calcium carbonate (limestone) is used in blast furnaces to capture impurities and form a slag that floats above the molten iron to keep the impurities from mixing back into the iron.
How do limestone roofs in Bermuda disinfect rainwater?
Limestone roofs in Bermuda naturally disinfect rainwater as it passes through the porous material. The high pH level of the limestone helps kill bacteria and impurities in the rainwater, making it safe for collection and use. Additionally, the limestone filters out debris and contaminants as the water seeps through.

Why are some limestone yellow or green?
Limestone can appear yellow or green due to the presence of impurities like iron oxides, organic materials, or clay minerals. The coloration is often a result of these impurities being present in the limestone during its formation process.
What is the function of limestone in the furnace?
Limestone is added to the furnace as a flux to help remove impurities from the iron ore during the iron-making process. It reacts with the impurities to form slag, which can be easily removed from the molten iron.
Why limestone is used in the blast furnace?
Limestone is used in the blast furnace as a flux material to help remove impurities such as silica, which would otherwise form a slag that interferes with the smelting process. When limestone is added, it combines with the impurities to form a molten slag that can be easily separated from the molten iron.
Why is limestone added to the blast furnace during the extraction of iron?
Limestone is added to the blast furnace during the extraction of iron to act as a flux. It helps to remove impurities, such as silica, from the iron ore by combining with them to form slag. The slag can then be easily separated from the molten iron.
How can iron be removed from ores?
Usually be melting the ores and adding limestone to the mix to gather the impurities which rise to the surface of the container. The impurities are then skimmed off.

Why is Limestone is used to purify sugar?
Limestone is used to purify sugar because it helps remove impurities like sulfur dioxide, which can affect the taste and quality of the sugar. Limestone reacts with sulfur dioxide to form calcium sulfite, which then precipitates out along with other impurities, leaving behind a purer sugar solution.
Why is Limestone added to a Blast Furnace for producing Iron?
Limestone is added to a blast furnace to act as a flux, which helps remove impurities from the iron ore being smelted. It reacts with the impurities to form a slag that can be easily separated from the molten iron. This process helps increase the purity of the iron being produced.
How does calcium carbonate purify iron?
Calcium carbonate (limestone) is used in blast furnaces to capture impurities and form a slag that floats above the molten iron to keep the impurities from mixing back into the iron.
Is limestone used for smelting iron ore and making cement?
Yes, limestone is used in both processes. In smelting iron ore, limestone acts as a flux to remove impurities from the ore. In cement production, limestone is one of the main ingredients, along with clay or shale, to make clinker that is then ground into cement.
