How Lime is Produced - Arij Trading

Such sedimentary is a base for limestone formation. Lime production begins by extracting limestone from mines and quarries. Such extractions supplied from mostly open deposits adjacent to the lime factory, but in some cases known as subsea boreholes and even underground mines are also subject for extractions. A standard excavation process includes:
