Limestone to lime

In this activity, students view the interactive Calcination – lime from limestone, which shows the industrial processing of limestone into lime, and use the information to complete a matching activity.

By the end of this activity, students should be able to:

• describe the effect of heat on limestone
• define the term ‘calcination’
• outline the main process steps in the production of lime from limestone
• recall the meanings of the terms ‘exothermic’ and ‘endothermic
• write word and symbol equations for the main chemical reactions occurring
• distinguish between the terms ‘limestone’, ‘lime’ and ‘slaked lime

Calcination

Lime, produced by calcining limestone, plays a key role in a multitude of industrial, manufacturing and agricultural processes.

This interactive outlines the process steps taken at the McDonald’s Lime Limited Ōtorohanga plant.
