Lime is one of the oldest and vital materials used by humans. Lime word refers to products derived from burnt limestone, such as quicklime and hydrated lime. It is naturally occurring and consist high levels of calcium and magnesium carbonate with small amounts of other minerals. Lime is extracted from underground mines all over the world.
Ground limestone: Ground limestone contains CsCO3 and some impurities. But some limestone also includes MgCO3. If ground limestone contains 1-6% Mg is called Calcite limestone and if it has 6%Mg or more it is called Dolomitic Limestone.
Burned limestone: It is a ground limestone that is obtained after exposed to high temperature to remove carbon dioxide. Magnesium oxide (MgO) will also be present if it was in the ground limestone prior to being cooked. It must be handled carefully because it reacts quickly with water creating hydrated lime and releasing large amounts of heat.
Hydrated Lime: It is calcium hydroxide (Ca(OH)2). It is very fast acting and powdery lime material. It is caustic and can easily burn plants that are already established.
It is a fundamental aspect of soil, which is playing a major role in overall business profitability and environmental diversification recognized by farmers. Soil is a vital resource to the farmers and it is therefore crucial that he looks after it in both the short and long-term.
It is one of those usually unseen products that have a profound effect on our daily lives. It is used in manufacturing process such as food industry, agriculture and many environmental applications.
