How do you make limestone from lime?

Jun 04, 2020 · Beside this, how is lime made from limestone? Lime is produced through the calcination of limestone (calcium carbonate) in a lime kiln at temperatures at or above 2000 degrees Fahrenheit. The product of calcination of high calcium limestone is "quicklime" or calcium oxide. Quicklime in turn can be reacted with water to produce hydrated lime (calcium hydroxide).

First a vault of limestone blocks is built over the furnace, above which the rest of the limestone is stacked. The fire is lit and kept stoked for several days until all the limestone has been calcined. The kiln is then unloaded, the lime sent to the slaking pits, and the process repeated with the next batch of limestone.
