Calcination step 2: At the quarry

Transcript

Narrator

After identifying the desirable limestone rock for extraction, a drill and blast method of extraction is used. An excavator loads the loosened limestone into dump trucks for delivery to the on-site crushing plant. This continuous-feed process crushes limestone chip into a range of sizes. Limestone chip 15–50 mm in size is sent to the calcination plant, while other sizes are used in other processes.
