Summary:The calcium carbonate can be processed into quicklime and quicklime becomes slaked lime by adding water, While the component of limestone is calcium carbonate. Processing and mining of limestone is very important.
Quicklime VS Slaked Lime VS Limestone
The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are widely used as building materials and are also important raw materials for many industries. Calcium carbonate can be directly processed into stone and burned into quicklime, but it is also dangerous in the production process. Quicklime becomes slaked lime by absorbing moisture or adding water, and slaked lime is also called hydrated lime.
Lime includes quicklime and slaked lime. The main component of quicklime is CaO, which is generally lumpy, pure white, and light gray or light yellow when it contains impurities. The main component of slaked lime is Ca(OH)2. The slaked lime can be formulated into lime slurry, lime paste, lime mortar, etc., which are used as coating materials and brick adhesives.
Limestone is mainly formed in a shallow sea environment. Limestone generally contains some dolomite and clay minerals. When the content of clay minerals reaches 25% to 50%, it is called argillaceous rock. When the dolomite content reaches 25%~50%, it is called dolomitic limestone. Limestone is widely distributed, uniform in lithology, easy to be mined and processed, and is a kind of very versatile building material.
Status Quo Of Limestone Mining And Utilization
The mining and utilization situation is uneven. The current problems are:
1. Low Resource Utilization
At present, the utilization rate of limestone mines that are officially mined has reached more than 90%, while the utilization rate of civilian mining resources is only 40%. Because the amount of civilian mining is greater than that of mechanized mining, it is estimated that the utilization rate of the entire limestone is about 60%.
2. The Scale Of The Mine Is Small And The Mining Technology Is Backward
There are several or even more than a dozen small mining mines around a mountain. This backward mining method not only has low labor efficiency, great safety risks and serious waste of resources, but also causes large-scale destruction of mountain and vegetation, causing serious harm to the ecological environment around the mining area.
How to incorporate the technological progress of the mine into the overall plan of the technological progress of the enterprise, carry out the overall plan for the development of the mine, and deal with the relationship between recent mining and transportation mining, high-grade and low-grade, high-quality and inferior quality, reasonable mining, comprehensive utilization, reducing the stripping ratio, and expanding the utilization rate of mine resources are very worthy of study.
In view of this, SBM Group specially introduced special limestone processing equipments, which can effectively improve the limestone mining efficiency:
