When quarrying stone there may be areas in the Quarry where there is a large amount of clay contamination. These occur particularly in Limestone Quarries where the clay sediments collect in fissures in the stone. This clay slows down the Crushing and Screen process, so it is scalped off at a size generally 80mm 100mm.Waste incineration and many other industrial processes generate flue gases. These often contain pollutants such as sulfur oxides SO2 SO3, hydrochloric acid HCl, hydrofluoric acid HF as well as heavy metals, dioxins and furans. Lime, hydrated lime and limestone-based products are highly efficient reagents for capturing contaminants. When mixed with other components,
