quick lime - Raj Associates - Mining Of Limestone and Manufacturing of Lime

Quicklime, more formally known as calcium oxide (CaO), is a caustic alkaline substance which is produced by heating limestone in specially designed kilns. There are a wide range of uses for quicklime, ranging from mortar to flux, and the substance has been used by humans for centuries

We are engaged in offering good quality Quick Lime that is free from impurities. Quick Lime are the highly reactive product is essential in many industrial processes. Moreover, we offer Quick Lime in various grades and at market leading prices.

Limestone decomposes into quicklime and carbon dioxide

CaCo3              –>  CaO +  CO2

By weight 100 –>  56    + 44

hydrated lime - Raj Associates - Mining Of Limestone and Manufacturing of Lime

Hydrated Lime is produced by reacting Quick Lime with water in continuous hydration. The end product is a fine dry powder. If a precisely controlled amount of water is added to quicklime, a (violent) reaction ensues with much evolution of heat. In the chemical reaction with water, the lumps of quicklime break down to a dry fine white powder known as hydrated lime.

Quicklime   + (a controlled amount of ) water à hydrated lime (also called lime hydrate)

CaO             +                  H2O                          à  Ca(OH)2

Hydrated lime is used for water treatment, Soil stabilization, in construction, caustic soda, bleaching powder, pickling of steel, sanitation protective points for buildings, as whitening agents in sugar industry, in Putty plants etc

Limestone is a sedimentary rock composed principally of calcium carbonate (calcite-CaCO3). It is commonly composed of tiny fossils. It is generally gray in color.
Limestone has a wide range of applications. It is basic raw material for manufacturing of Quick Lime, Cement industries. It is used as a flux in steel and aluminum industries. Recently thermal plants have started using limestone for Flue-gas desulfurization.

Dolomite - Raj Associates - Mining Of Limestone and Manufacturing of Lime

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock is known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.
