In this work, we analysed the impact of adding several previously untested Sorbacal calciumbased substances to the raw limestone that is currently used for dry desulphurisation of browncoal fluidisedbed boilers. Our focus was to examine whether these additives could potentially improve the limestone SO 2 adsorption capacity. The main criterion was the time period for which each enriched ...

Extraction and processing. Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.. The excavated materials are transported to the crushing ...

Sinter is the primary feed material for making iron in a blast furnace. During the iron ore sintering process in iron and steel manufacturing, sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous beltfed furnace. The production of highquality sinter is crucial for assuring ...

Calcination is the main process of clinker production, calcining calcium carbonate (CaCO 3) at about 900 °C to form calcium oxide, CaO, lime, and the release of carbon dioxide gas (CO 2).In the next step of the socalled clinker treatment, calcium oxide (CaO) is exposed to temperatures of 1400 °C to 1500 °C together with silica (SiO 2), aluminum oxide (Al 2 O 3), and ferrous oxide (Fe 2 O 3).
