Limestone – Its Processing and Application in Iron and
Application of limestone and lime in iron and steel plant. During the production of iron by blast furnace (BF) route, limestone is added either in the process of sintering or as a direct feed in the blast furnace. Limestone is normally added during ironmaking for obtaining either neutral or slight basic BF slag.

Limestone is a naturally occurring white to off-white, mineral comprising calcium carbonate, CaCO3, whereas dolomite is a white to light brown mineral mostly comprising a bi-molecular struc-ture of calcium and magnesium carbonate. Colour differences reflect impurities such as clay, sand, organic remains and trace mineral constituents.

Moreover, barium carbonate has also been used as a reactive matrix in a passive remediation system, removing 90% of the sulfate from an alkaline mine water (Gomez-Arias et al., 2015). Unlike limestone, however, barium carbonate is scarce in nature (the mineral witherite), and therefore, the manufactured powder is expensive.

Your question doesn't clarify why you'd rather drop stones in the pump than to replace the stones in a filter cartridge. Regardless, the reaction between acidic water and caustic stone is going to take place anywhere they meet. I've seen limestone dropped into acidic rain water barrels to raise the pH for watering gardens.

The material was produced by calcining raw limestone powder at a rate of 10 °C/min to a temperature of 950 °C using a high-temperature furnace. The maximum temperature was maintained for 60 min to optimize decarbonation before a cooling regime was applied to the ambient temperature at a rate of approximately 1.9 °C/min.
