Limestone is a rock comprised mainly of calcium carbonate (chemical structure: CaCO3). This is a mineral called calcite. It typically forms in calm, clear, warm, shallow oceans. Limestone is usually a sedimentary rock, meaning that it is formed by an accumulation of layers. These layers are the shells, coral, algae, fec…See more on yesdirt

A limestone water treatment plant in Finland has successfully reduced the amount of ammonia present in the drinking water to just 20%. ... It assists in softening water as well as water purification and pH coagulation. In short, limestone affects the quality of water positively.
What is pellet softening? Pellet softening is a fluidized bed reactor technology for precipitation-based water softening. It uses caustic soda or lime to raise the pH of the water to create a precipitation reaction to reduce calcium in the water. The chemistry principles behind pellet softening is similar to that of lime softening, which has been traditionally used in drinking …
Here's how it works: Cement is made by grinding up limestone and then heating it, along with clay or shale, in a kiln. The temperature of the kiln ranges from 2,700 – 3,000 degrees Fahrenheit. During this process, CO2 is released in two ways: 1) from the fossil fuels used to heat the kiln and 2) from gases released from the limestone itself.
The largest use of lime is in steel manufacturing where lime is used as a flux to remove impurities such as phosphorus and sulfur. Lime is used in power plant smokestacks to remove sulfur from the emissions. Lime is also used in mining, paper and paper pulp production, water treatment and purification, and in wastewater treatment.
Africa, isolated high-grade deposits of limestone occur. This has resulted in lime production being limited to a few plants, with a fairly large output. Thus some South African plants are, by global standards, considered large production plants. Secondly, South Africa's well-developed uranium and gold operations are strongly dependent on
