Lime mud is a byproduct produced in pulp mills as part of the process that turns wood chips into pulp for paper. The pulp mill cooks wood chips with sodium hydroxide to extract the wood fiber used to make paper from the lignin that binds the wood together. During this process, sodium hydroxide is converted to sodium carbonate. The pulp mill than adds calcium oxide, also known as quicklime, to ...

Limestone is needed in steelmaking as a fluxing agent. Some steel mills add limestone to the blast furnace and use unfluxed taconite pellets, while others have found that pellets fluxed at the taconite plant will produce higher tonnages of steel more efficiently. In event of the latter, the limestone thus arrives by

ABSTRACT. Wet flue gas desulfurization (WFGD), using limestone with forced oxidation (LSFO), is a common Flue gas desulfurization (FGD) process where limestone reacts with SO 2 to produce gypsum (CaSO 2 O). In South Africa, Eskom's Kusile Power Station utilizes conventional wet ball milling to grind highgrade limestone (96% CaCO 3) to 95% passing 45 µm prior to use in the FGD scrubber.
