A salt, water and carbon dioxide.
Carbonate rocks such as limestone, composed mostly of the mineral calcite (CaCO3) are very susceptible to dissolution by groundwater during the process of chemical weathering. Such dissolution can result in systems of caves and sinkholes.
Limestone is initially crushed using crushers like jaw crushers, impact crushers, and hammer crushers. The crushed limestone is then screened to classify it into different sizes suitable for subsequent lime production process. Limestone, a sedimentary rock, comes in different density ranges: 1. Low-density limestone: 1,760-2,160 kg/m³. 2.
Although it is a slower process in nature, this same reaction happens to limestone acidic rain reacts with it, producing carbon dioxide. Cite Top contributors to discussions in this field

Your solution's ready to go! ... Question: What is the purpose of adding limestone (CaCO3) when smelting iron ore? What is the purpose of adding limestone (CaCO 3) when smelting iron ore? There are 2 steps to solve this one. Solution. Step 1. Limestone (C a C O 3) is commonly used in the smelting process of iron ore as a fluxing agent. The ...
Solution – minerals are dissolved in the water and carried along in solution. This typically occurs in areas where the underlying bedrock is limestone or chalk; Suspension – fine, light material such as alluvium is carried along in the water. This is known as suspended load.
Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with …

There are different types of chemical weathering, the most important are: Solution - removal of rock in solution by acidic rainwater. In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation). Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts.
Biochemical rocks form from organisms that were once alive, such as limestone from marine shells, whereas inorganic chemical rocks form from non-biological processes, such as salt that is left behind when a lake evaporates.
Since limestone most frequently comes from particles in water, Limestone deposits often form in or near a water supply. Coral reefs often have a limestone base with living creatures that depend on the limestone creating a layer over the rock. In certain areas, you might also find limestone formations around lakes and on dry land.
