The addition of ag-lime elevates soil pH to increase crop yields across a wide range of soil conditions. Ag-lime is often used to improve the physical structure of the soil by reducing surface crusting, increasing water retention and reducing soil erosion. Ag-lime treatment helps crops to better tolerate drought and wet conditions by increasing both root penetration and water percolation through the soil.
Quicklime is an essential chemical required to treat low quality soils in order to improve the soils workability and load bearing characteristics. Quicklime, hydrated lime and hydrated lime slurry are all utilized for these purposes along with providing an improved working surface. Hydrated lime has been recognized for years as an excellent anti-stripping agent for asphalt pavements.
Throughout the pulp and papermaking processes quicklime is essential. Quicklime is used to recover valuable caustic soda in the pulping process. It is also used in the water softening processes for pulp and paper mills. Pulverized limestone (PLS) or rock dust is used in underground mines to minimize methane concentrations and combustible dusts as well as enhance mine illumination.
Quicklime is utilized by the steel industry to effectively remove phosphorus, sulfur and silica in the basic oxygen furnace and electric arc furnace. Electric arc furnace steel makers may also use a ladle metallurgical furnace as a secondary refining process to produce cleaner steels for more demanding applications.
